Abstract:

The ocean attracts and inspires thousands of students every year to pursue degrees in science, engineering, and technology. Yet, in spite of all the attention paid to the oceans, students often lack the information needed to make wise decisions about choosing an ocean-related career. The Center for Ocean Science Education Excellence ? California (COSEE California) and the Marine Advanced Technology Education (MATE) Center have responded to this problem by developing a user-friendly interactive Web site on ocean careers (www.OceanCareers.com).

Abstract:

Merchant marine vessels have provided invaluable information about weather and climate over the seas. In this note, it is shown how these vessels also contribute to ocean research through systematic surveys of upper ocean temperature, salinity and currents. By repeatedly sampling a particular route, one can obtain an accurate picture of the mean state of the ocean and where and how it varies. With a few examples drawn from our own work we show how commercial shipping and cruise vessels, with their unparalleled access to the oceans, could give society far more extensive and valuable information about upper ocean and atmospheric conditions on a regular basis. But for this to happen, a new generation of ocean instrumentation needs to be developed that is optimized for completely automatic and unattended operation on such vessels. It also means working with the merchant marine community to develop guidelines and procedures for future cooperative efforts.

Abstract:

AbstractAccording to National Oceanic and Atmospheric Administration's (NOAA's) official economic statistics, over half of the U.S. population lives within 50 miles of the coast. At sea, maritime commerce has tripled since about 1960‐2010. The National Weather Service (NWS) Marine Program has a mission to provide marine forecasts and warnings for the U.S. coastal waters and Great Lakes, offshore and high seas portions of the Pacific and Atlantic Oceans, Gulf of Mexico, Caribbean, and for a portion of the Arctic Ocean (north of Alaska). This information helps protect people and their property while on our nation's waters. Weather and ocean data are critical to the mariner. This is due to a combination of hazards—such as strong wind and large waves—and the fact that the mariner is often isolated. When in peril, rescue of these vessels may be hours or days in coming. Not having accurate and timely weather information and the knowledge to properly apply it increases risk to mariners and their vessels. In coastal areas, NWS provides vital services and products to inform and protect residents, businesses, tourists, and others from hazardous weather and surf conditions. Typically in the coastal community, rip currents and inundation caused by storms and unusually high tides are the primary focus. Techniques of marine forecasting have come a long way, bringing us into the modern era of marine observations via satellite, radar, and buoys and forecasting using sophisticated computer programs. The role of marine weather forecasters worldwide is a complex one and will continue to change in response to evolving technology and user requirements.

Abstract:

Abstract Maritime and underwater cultural heritage (MUCH) is concerned with the relationship between people and the marine and coastal environment over time. Rooted in the past, MUCH is a resource that can help us understand and appreciate our current situation. But MUCH is also a medium through which we address the future to develop resilience and motivate adaptation. MUCH is both a source of inspiration and of evidence: to study and understand it requires and develops interdisciplinary skills across the social sciences, STEM, and SHAPE subjects.The UN Decade of Ocean Science for Sustainable Development 2021‐2030, in promoting a common framework for supporting stakeholders in studying the world's oceans, presents a vital opportunity to improve the integration of MUCH within the marine sciences. The Ocean Decade Heritage Network's Decade Action, the Cultural Heritage Framework Programme, focuses on ensuring that MUCH specialists—archaeologists and cultural heritage managers—can engage constructively with the marine sciences under the auspices of the Ocean Decade, and make the best of the opportunity that the Ocean Decade presents in addressing present and future challenges facing the world's oceans.

Abstract:

Abstract The “Measuring the Pulse of Earth's Global Ocean” project will attempt to quantify sound levels in what should be the quietest parts of the ocean—the five deepest locations—to gauge the baseline level of sound in these remote ocean areas. Ocean noise from human-made sources of sound (e.g., shipping) can have a detrimental effect on marine animals that use sound to sense their environment. Thus noise can negatively impact the health of marine ecosystems, which are the basis for many sectors of the global “Blue” economy, including commercial fisheries and aquaculture. This project will gather unique baseline data to monitor the “acoustic health” of the oceans. A novel, deep-ocean capable hydrophone-lander system will be deployed at each of these five deep-sea sites (all >7 km deep). The project will involve the collaboration of several U.S. governmental agencies, private industry and NGOs, and international partners to access these global locations. We will collaborate with scientists from each of these five sites to deploy, recover, and analyze this deep ocean acoustic data. Our ocean sound program aspires to develop a robust and inclusive education/outreach program, focusing on the impact of underwater noise on the health of marine ecosystems.

Abstract:

Abstract: According to the United Nations, aquatic pollution affects at least 800 species worldwide, with plastic responsible for up to 80% of the waste. Every minute, up to 13 million metric tonnes of plastic is expected to end up in the ocean, the equivalent of a trash or garbage truck load. Plastic is a design failure; it was never intended to end up in animals' stomachs or at the bottom of the food chain in humans. The fashion industry is a massive contributor to the plastic waste found in the oceans and so it becomes necessary for corporations to take sustainable steps in the direction of reducing Ocean Plastic Pollution. One of the ways to do so would be by recycling ocean plastic into clothes. Our study focuses on analysing global collaborations and suggesting a series of steps for recycling ocean plastic.

Abstract:

Humanity faces the global challenge of safely removing CO2 from the atmosphere to secure a stable climate. Broadly, there are three options: terrestrial, soils and ocean, and coastal blue carbon sinks. Each option has unique characteristics in relation to permanence, leakage, environmental integrity and co-bene?ts. This extended abstract explores opportunities for blue carbon projects and highlights the important role of engineers in advancing the success of these innovative techniques. Examples of blue carbon include salt marshes, mangroves, seagrasses, macro-algae, coral reefs and open-ocean micro-algae. Regional case studies for mangrove rehabilitation and pioneering research in Australia on micro-algae and open-ocean sequestration are also presented. The world’s oceans contain about 90% of the global carbon budget. Nearly half of global primary productivity occurs in the open-ocean; this productivity has been achieved using only 0.05% of the earth’s biomass. Coastal and marine systems are ef?cient at the continuous storage of carbon, retaining it for centuries. Co-bene?ts include coastal protection, ?sh nurseries, marine biodiversity and improved water quality. Blue carbon is therefore not only direct mitigation, but also a major contributor to the adaptation of changing climate, building a more resilient ecology and supporting long-term sustainability, including that of the major carbon-based industries. Engineers are well equipped to lead this blue revolution while working with scientists and carbon professionals. This extended absrtact highlights opportunities for fast-track implementation and the engineering challenges; it draws on case studies to show scaleable solutions for achieving climate and food security.

Abstract:

Ocean fertilization was first introduced as a carbon dioxide mitigation technique in the 1980s. However, its effectiveness to slow down climate change is uncertain and it is expected to damage the marine environment. Consequently, international law, including the London Convention/Protocol and the Convention on Biological Diversity, limits this activity to scientific research purposes. The applicability and scope of existing treaties for regulating this activity have been reviewed within international legal systems, in particular within the London Protocol. The establishment of a liability regime with respect to these activities has also been raised during a discussion on regulation of ocean fertilization under the London Protocol. One of the key purposes of the liability regime could be to make ocean users more cautious when exploring and exploiting the oceans through charging cleaning costs or imposing compensation for damage. This paper aims to identify such a preventative effect of the international liability regime, in particular, state liability.

Abstract:

The ocean is considered the new economic frontier due to its potential for resource wealth and economic growth driver. However, the ocean faces increasing pressures from overexploitation, pollution, biodiversity decline and climate change. In this context, the concept of Blue Economy emerges, which seeks to reconcile economic development with the environmental sustainability of the oceans and coastal areas. Its connection with the UN Sustainable Development Goals (SDGs), in particular SDG 14 - Life in Water, is a challenge due to possible competitions and conflicts between individual or industrial goals. The Blue Economy encompasses both established and emerging sectors, and is promoted as a strategy to protect the world's oceans and water resources. SDG 14 seeks to conserve and sustainably use the oceans, seas and marine resources, and has driven global efforts in this regard, such as creating marine protected areas and reducing marine pollution. Identifying the synergies between the Blue Economy and the SDGs is essential to harnessing the full potential of the ocean in a responsible and sustainable way.

Abstract:

The issues surrounding marine mammals and noise cannot be managed effectively without an understanding of the effects of that noise on individual mammals and their populations. In the spring of 2003 the National Research Council released Ocean Noise and Marine Mammals, a report that reviewed sources of ocean noise (natural and anthropogenic), the effects of noise on marine mammals, patterns and long-term trends in ocean noise, and included recommendations intended to improve understanding of the sources and impacts of anthropogenic marine noise. This paper provides a brief summary of observed effects of ocean noise on marine mammals and the factors that can change the response of the animal to the noise exposure. It introduces the reader to short- and long-term behavior changes that have been observed in marine mammals in response to ocean noise, and discusses future directions for marine mammal research.

Abstract:

AbstractMarine mammals are under growing pressure as anthropogenic use of the ocean increases. Ship strikes of large whales and loud underwater sound sources including air guns for marine geophysical prospecting and naval midfrequency sonar are criticized for their possible negative effects on marine mammals. Competent authorities regularly require the implementation of mitigation measures, including vessel speed reductions or shutdown of acoustic sources if marine mammals are sighted in sensitive areas or in predefined exclusion zones around a vessel. To ensure successful mitigation, reliable at-sea detection of animals is crucial. To date, ship-based marine mammal observers are the most commonly implemented detection method; however, thermal (IR) imaging–based automatic detection systems have been used in recent years. This study evaluates thermal imaging–based automatic whale detection technology for its use across different oceans. The performance of this technology is characterized with respect to environmental conditions, and an automatic detection algorithm for whale blows is presented. The technology can detect whales in polar, temperate, and subtropical ocean regimes over distances of up to several kilometers and outperforms marine mammal observers in the number of whales detected. These results show that thermal imaging technology can be used to assist in providing protection for marine mammals against ship strike and acoustic impact across the world’s oceans.

Abstract:

Ocean engineering is a broad branch of engineering covering all aspects of engineering associated with the design, construction and operation of fixed and floating structures in the marine environment. It differs from naval architecture which traditionally focusses on ships and related ocean vehicles, and is of relevance to engineers in the offshore oil and gas industry.The Australian Maritime College (AMC) commenced running Australia’s first Bachelor of Engineering (Ocean Engineering) degree in 1997, with the first students graduating in 2000. The program was designed to meet the growing need of the Australian offshore oil and gas industry for graduate engineers skilled in the analysis and design of structures and facilities capable of operating in ever-increasing water depths. It builds on the already successful naval architecture degree offered by AMC, and has the first year completely in common.AMC makes use of its uniquely maritime focus and its wide variety of specialist facilities to produce graduates with a strong hands-on approach to complement their theoretical studies. The program features a unique blend of traditional marine and ocean-related subjects with a thorough grounding in hydrodynamics, wave theories, reservoir engineering, drilling technology, well design, offshore operations, oil and gas production technology and sub-sea engineering. As such, it is believed that the syllabus has a composition that is basically unique in the world.To support this new degree, AMC has commissioned the construction of a new Model Test Basin to complement its existing towing tank. This will have a plan form of 35 x 12 m and will be equipped with multi-directional wavemakers, making it ideal for student use, as well as consulting and staff research.The aim of the program is to produce engineering graduates with a broad theoretical background and a practical approach to problem solving. The ocean engineering graduates from AMC will be exceptionally well equipped to pursue successful careers within the international oil and gas industry.This paper describes briefly the various subjects that are unique to the ocean engineering degree and shows how the subject syllabi come together into a coherent program which will produce systems engineers rather than specialists. The course has just recently received Full Accreditation from The Institution of Engineers, Australia (IEAust).

Abstract:

The Conceive Design Implement Operate (CDIO) initiative is an innovative engineering education framework aiming to produce industry-ready graduates. Over the past two decades, the approach has been increasingly popular, particularly in the mechanical engineering field, thanks to its practical approach and outcome-based assessments. However, the CDIO approach remains absent from the pedagogical tools employed in marine engineering education curricula. This paper argues that, although unrecognized as such, modern marine engineering courses have been employing an approach akin to that of the CDIO initiative. Four international case studies, in both undergraduate and postgraduate higher education, are employed to demonstrate that the marine engineering courses under consideration indeed utilize the CDIO approach to engineering education. Furthermore, this paper identifies the CDIO initiative as a relevant pedagogy for the development of novel marine engineering courses and activities. It is anticipated that this first recognition of the use of the CDIO initiative in marine engineering education will contribute to formalizing the implementation of the CDIO initiative in this field, as well as enable greater synergies between the various disciplines of engineering education.

Abstract:

Abstract The oceans make this planet habitable and provide a variety of essential ecosystem services ranging from climate regulation through control of greenhouse gases to provisioning about 17% of protein consumed by humans. The oceans are changing as a consequence of human activity but this system is severely under sampled. Traditional methods of studying the oceans, sailing in straight lines, extrapolating a few point measurements have not changed much in 200 years. Despite the tremendous advances in sampling technologies, we often use our autonomous assets the same way. We propose to use the advances in multiplatform, multidisciplinary, and integrated ocean observation, artificial intelligence, marine robotics, new high-resolution coastal ocean data assimilation techniques and computer models to observe and predict the oceans “intelligently”—by deploying self-propelled autonomous sensors and Smallsats guided by data assimilating models to provide observations to reduce model uncertainty in the coastal ocean. This system will be portable and capable of being deployed rapidly in any ocean.

Abstract:

The National Oceanic and Atmospheric Administration (NOAA) operates a network of automated moored buoys in the oceans whose installation began in the early 1970s. What began as a research and development program consolidating independent U.S. buoy projects, by the mid-1980s evolved into an operational activity when the National Data Buoy Center (NDBC) was moved into NOAA's National Weather Service (NWS). Except for a few reimbursable projects requiring ocean data, little effort was placed on sustained ocean monitoring, as NDBC focused upon satisfying NWS' mission requirements. NOAA's recent direction to become a “matrix” organization is leading to greater utilization of assets across its line offices. NDBC and its Marine Observing Network (MON) of moored buoys and fixed stations have become recognized as NOAA assets that can help meet NOAA-wide strategic goals. This paper describes some of NDBC's history and the future role it can play as part of a federal “backbone” system to support scientific needs of the community that works in the oceans.

Abstract:

The increase in partial pressure of CO2 in the oceans directly affects the productivity and survival of coastal industries and ecosystems. For marine aquaculture, the decreased alkalinity of seawater results in reduced availability of carbonates for marine organisms to build their shells, leading to decreased aquaculture quality and productivity. The industry has been implementing recirculating aquaculture systems (RASs) to reduce CO2 in feedwaters, but recent interest in ocean-based CO2 capture has led to additional strategies that may be relevant. The new methods in addition to CO2 removal offer capture options for enhanced aquaculture sustainability. Here, we review and compare early-stage and commercially available technologies for deacidification of seawater and their suitability for aquaculture. Most methods considered rely on a voltage-induced pH swing to shift the carbonate/bicarbonate equilibrium toward the release of CO2, with subsequent capture of the released CO2 as a gas or as solid mineral carbonates. The modular design and distributed deployment potential of these systems offers promise, but current demonstrations are limited to bench scale, highlighting the need for sustained research and development before they can be implemented for marine aquaculture.

Abstract:

AbstractMarine renewable energy (MRE) encompasses the harvest of energy from the movement of ocean waters in the form of either currents or waves, as well as temperature and salinity differentials. To date, most MRE development has focused on utility-scale electrical grid generation, but a growing body of work focuses on non-grid applications in the blue economy where MRE could provide power on-site and at the scale needed for specific maritime sectors. One of the blue economy sectors with promising applications for MRE is ocean observations using both mobile and stationary platforms. This paper documents the steps and results of engaging with experts across the myriad ocean observation platforms and capabilities to inform five use cases. These use cases include descriptions of specific ocean observation applications performing measurements of high societal value (e.g., data for weather forecasting and tsunami detection) that closely resemble specific sensing systems and, in most cases, are placed in a particular area of the ocean. Rapid resource assessments (i.e., first-order estimates) were performed at these locations to determine the suitability of marine and other renewable energy sources. From the information gathered so far, MRE has significant potential to enable improved ocean observation missions, expand ocean observing capacity, and develop as an industry in parallel with the needs of our changing oceans.

Abstract:

Abstract This paper presents a new approach to the existing training of marine control engineering professionals using artificial intelligence. We use optimisation strategies, neural networks and game theory to support optimal, safe ship control by applying the latest scientific achievements to the current process of educating students as future marine officers. Recent advancements in shipbuilding, equipment for robotised ships, the high quality of shipboard game plans, the cost of overhauling, dependability, the fixing of the shipboard equipment and the requesting of the safe shipping and environmental protection, requires constant information on recent equipment and programming for computational intelligence by marine officers. We carry out an analysis to determine which methods of artificial intelligence can allow us to eliminate human subjectivity and uncertainty from real navigational situations involving manoeuvring decisions made by marine officers. Trainees learn by using computer simulation methods to calculate the optimal safe traverse of the ship in the event of a possible collision with other ships, which are mapped using neural networks that take into consideration the subjectivity of the navigator. The game-optimal safe trajectory for the ship also considers the uncertainty in the navigational situation, which is measured in terms of the risk of collision. The use of artificial intelligence methods in the final stage of training on ship automation can improve the practical education of marine officers and allow for safer and more effective ship operation.

However, when the ocean was deeply explored, the pollution and deterioration of marine environment have become a worldwide issue. In order to maintain the growth of marine economy and protect the marine environment, it is necessary to employ the perspective of sustainable development to take the relationship between marine economy and marine environment as a coupling mechanism. In this paper, the data of marine economy and marine environment in China were analyzed and the development of marine economy and marine environment were divided into three steps. Based on this analysis, the symbiotic relationship of marine economy and marine environment was revealed.

Abstract:

Deep ocean science is poised to enter a new millennium characterized by cooperation among scientists of many different disciplines who are seeking to gain an understanding of the complex linkages between physical, chemical, biological, and geological processes occurring at and beneath the ocean floor in the world oceans. This multidisciplinary imperative has been spurred by unprecedented advances in understanding the complexities and interdependence of these phenomena made possible through research that used deep submergence vehicles over the past two decades. Marine scientists of all disciplines are forecasting that the next decade will see even greater linkage between oceanographic disciplines. The need to understand the temporal dimension of the processes being studied will sustain continued use of deep ocean submersibles and utilization of newly developed, remotely operated vehicles (ROVs) and autonomous underwater vehicles (AUVs) for conducting time-series and observatory-based research in the deep ocean and at the seafloor. These approaches will enable marine scientists to achieve a greater understanding of global processes and of climate change and geochemical mass balance. These same approaches will enable them to grapple with intriguing problems concerning the interrelated processes of crustal generation, evolution and transport of geochemical fluids in the crust and into the oceans, and origins and proliferation of life both on Earth and beyond.

Abstract:

Advanced marine observation infrastructures are the most significant scientific tool for the study of marine ecosystem trends and shifts. Ocean monitoring technologies, though highly demanding and expensive, are essential for the monitoring and long-term study of oceanic systems. The POSEIDON system for monitoring and forecasting the marine environment is an augmented research infrastructure, unique in the Eastern Mediterranean basin, contributing to the European Ocean Observing System implementation, focusing—among others—on biogeochemical observations and deep-sea ecosystem and geological processes. The technological evolution of the POSEIDON system through a science-coupled strategy supported by engineers and scientists, resulted in a state-of-the-art ocean observing system. There has been a continuous expansion of the infrastructure with new scientific platforms and supporting facilities. Innovative sensing technologies were introduced in the operational data acquisition and new methodologies and tools were developed to improve the system operations and efficiency. As a part of the scientific community of ocean observatories, POSEIDON contributes actively to the improving of the ocean observing. International access to engineering and field demonstrating services, data products and technology testing facilities has been offered to scientists and industry partners. POSEIDON is a widely recognizable international technology testing/demonstrating node specializing in marine technology providing high-level services.

Abstract:

Marine Environmental Education (MEE) is a vital activity, since the marine environment is impacted by industrial and technologies involved in this sector. MEE is in strong connection with marine engineering. The players from this industry have to comply with environmental protection protocols and conventions. A marine cluster is a good way of approaching issues specific to the exploitation of resources of the sea. In the present, a particularity of marine pollution is that in enclosed seas (such as Black Sea is) and on coastal areas, the pollution is higher than in the open ocean. In order to fight with this reality, it is also vital to increase the public environmental awareness throughout specific education, not only to train specialists in this respect. This paper is providing the pylons on which MEE relies. From this paper will succeed how the objectives of MEE (awareness, knowledge, attitude, skills, participation) and its specific actions (environmental education and training, involvement, bringing people together) are supported by a marine cluster. The most important result of this study can be stated as: processes developed within MEE will enforce the involvement of specialists in solving marine pollution issues and will rise the environmental consciousness of communities, in a framework provided by a cluster oriented towards MEE.

Abstract:

Abstract Animal-Borne Ocean Sensors—AniBOS—is an emerging network of the Global Ocean Observing System (GOOS). AniBOS makes freely available oceanographic measurements across the hard-to-observe world's polar and tropical oceans from miniaturized sensors attached to marine animals. These data complement conventional approaches by providing both physical and ecological data in remote ocean regions directly at the scale and resolution at which animals move. AniBOS fills an important observational gap by integrating animal-collected data within the GOOS to improve our ability to observe and predict global climate processes and animal behavior, both of which are essential components of the Decade of Ocean Science.

Abstract:

Abstract Oceans cover 72% of the Earth's surface, house immense living and non-living resources, and play a key role in regulating the planet's climate. Robotic vehicles are essential for exploring vast deep-ocean resources, spatiotemporal monitoring of oceans to understand the patterns of climate change, monitoring marine pollution, providing defense, and identifying assets lost in the oceans. The article discusses key design considerations for realizing safe, reliable, and efficient deep-ocean unmanned and manned robotic vehicles capable of operating in challenging environments characterized by high hydrostatic pressure, low temperature, salinity, darkness, dynamic medium, and soft seabed conditions. Strategic technologies to enable cost-effective and increased spatiotemporal monitoring including homing and docking stations, autonomous intervention vehicles, swarm robotic systems, and bio-inspired vehicle designs are discussed.

Abstract:

The development of marine equipment is an international trend. It is also a strategic choice for coastal countries, as the basis to construct a strong marine power. For this purpose, the Chinese government has strengthened the support for marine equipment research and development in recent years. For most researchers, however, they cannot test their marine equipment at an actual ocean site due to limited fund as well as because the devices are not easy to move. Hence, devices for simulating ocean waves are emerging on this basis. But these existing devices are not able to completely recreate the motion of an ocean wave. For this reason, this paper introduces a dynamic ocean wave simulator that is based on six-degrees of freedom parallel platform. The simulator consists of two components: a boat model placed on the sea and a six-degrees of freedom platform kept in a room. The boat is used to collect data of the ocean wave motion, and the data are simultaneously transferred, via a general packet radio service wireless network to a controller equipped on the platform. The controller will make calculation of the data and then control the platform to perform motions accordingly, whereby the ocean wave motion can be recreated. After being designed, the simulator is tested in the lab. The results show that the simulator can simulate simple ocean waves and satisfies the requirements of ordinary marine projects.

Abstract:

Abstract Persistent mobile ocean observation platforms, supported by arrays of subsea marine vehicle service stations, will enable direct study of oceanographic and geological processes that, due to their transient nature and spatiotemporal variability, are not well understood. These include, but are not limited to, ocean-seafloor interactions and crustal ecosystems, mid-ocean ridge volcanism, coastal circulation and shelf ecosystems, reef health, and arctic sea-ice interaction. Further, certain types of subsea events, such as erupting submarine volcanoes, instabilities in methane hydrate deposits, marine mass-wasting events, turbidite flows, the ecological impacts of major earthquakes, breaking internal waves, the fate of mid-water vortices, and episodes of anoxic upwelling, can be energetic, transient, and unpredictable, often having unverifiable consequences. These cannot be readily detected, characterized, or quantified owing to the difficulty of anticipating the onset of such phenomena. The intractability of launching major sea-going assets with short lead times to capture and document such evanescent system-level processes from beginning to end means that our understanding of these and related processes is not readily expandable with current oceanographic tools.Marine Vehicle Highways (MVHs) will change the way ocean science is conducted by making temporally and spatially distributed data sets more attainable and accessible, opening the door for broader participation in transformative ocean science.

Abstract:

Microplastics are the biggest pollutants in marine ecosystems. Each year, over 8 million tons of plastic enter the oceans. Via microbes, microplastics may transport toxic chemicals into food webs. It is therefore important to create a way to remove microplastics and reduce the impact of microplastics on the ocean’s food web. This paper discusses the plan of using kiln firing, laser firing, pollution control, and green energy production to reuse marine plastics. We used a wood-fired kiln to design a kiln boat. The “Patch” is a large ocean area with trash. The calorific value of plastics is comparable to that of fuels, around 40 MJ/kg. This makes plastic a good fuel for ceramic firing. Based on our Taiwanese invention patent for a laser ceramic firing technique (Taiwan, R.O.C Patent Number: I687394 and I750055), we integrated a variety of ceramic technologies to address the problem of marine plastic pollution. A kiln boat is a good plan. Creating a moveable kiln not only reduces transportation costs but also reuses the calorific value of plastics. This is important in guiding future marine litter research and ocean cleanup management strategies.

Abstract:

Abstract People depend on biodiversity—the heart of healthy ecosystems—in many ways and every day of our lives. Yet usable knowledge of marine life is a missing link in the way we have designed marine observing and information systems. We lack critical biodiversity information to inform sustainable development from local levels to global scales—information on Essential Ocean Variables such as how many types and how much plankton, seagrasses, macro-algae, mangroves, corals and other invertebrates, fish, turtles, birds, and mammals are in any location at any one time, the value we may derive from that combination of organisms, and how this is changing with time and why. Marine Life 2030 is a program endorsed by the Ocean Decade to develop a coordinated system to deliver such actionable, transdisciplinary knowledge of ocean life to those who need it, promoting human well-being, sustainable development, and ocean conservation. Marine Life 2030 is an open network that invites partners to join us with ideas and energy to connect communities, programs, and sectors into a global, interoperable network, transforming the observation and forecasting of marine life for the future and for the benefit of all people.

Abstract:

Climate change has induced ocean deoxygenation and exacerbated eutrophication-driven hypoxia in recent decades, affecting the physiology, behaviour and ecology of marine organisms. The high oxygen demand of visual tissues and the known inhibitory effects of hypoxia on human vision raise the questions if and how ocean deoxygenation alters vision in marine organisms. This is particularly important given the rapid loss of oxygen and strong vertical gradients in oxygen concentration in many areas of the ocean. This review evaluates the potential effects of low oxygen (hypoxia) on visual function in marine animals and their implications for marine biota under current and future ocean deoxygenation based on evidence from terrestrial and a few marine organisms. Evolutionary history shows radiation of eye designs during a period of increasing ocean oxygenation. Physiological effects of hypoxia on photoreceptor function and light sensitivity, in combination with morphological changes that may occur throughout ontogeny, have the potential to alter visual behaviour and, subsequently, the ecology of marine organisms, particularly for fish, cephalopods and arthropods with ‘fast’ vision. Visual responses to hypoxia, including greater light requirements, offer an alternative hypothesis for observed habitat compression and shoaling vertical distributions in visual marine species subject to ocean deoxygenation, which merits further investigation. This article is part of the themed issue ‘Ocean ventilation and deoxygenation in a warming world’.

Corrosion of ocean engineering steel structures leads huge economic loses each year. To decrease corrosive loses and guarantee the safety of ocean steel structures, on the basis of Database on Corrosion of Ocean Engineering Materials and Structures (DCOEMS), the overall architecture of a digital simulation system is proposed based on the collection of existing models of corrosion damage on marine steel structures. Typical models involving uniform corrosion, pitting corrosion, stress corrosion and corrosion fatigue are sorted out and integrated in the simulation system which makes a thorough analysis for calculation and principle of professional module. The effective integration of corrosion damage, structural simulation and visualization is implemented successfully. It achieves the applications of the digital simulation. In the case of prediction and evaluation, it lays a good foundation for the development of the simulation system with independent intellectual property rights.

Abstract:

The paper begins by highlighting the importance and contributions of the various types of ocean wealth to human well-being. These range from oil, food and minerals to a medium for the transportation of bulk goods and a source of renewable energy. The commercial goal to be satisfied in order to achieve success is then stated and a methodology, based on a tree diagram approach, for identifying ocean market opportunities is described. Four examples relating to support for ocean activities are used to illustrate its application. These deal with underwater navigation systems, intermodal marine transport maritime and offshore safety, and dredging. The criteria for fully realizing the engineering potential are considered. They range from the importance of meeting the commercial goal and the impact of safety on ocean activities to the role of human factors and fresh educational methods. The need for an integrated approach to ocean wealth generation and the contribution of research and development efforts are discussed. The main conclusion is that many other forms of wealth with a potential market as large as that of offshore oil and gas are waiting to be ‘discovered’.

Abstract:

This paper focuses on mariner-ship interaction from the practical end of the design spectrum. Statistical data on marine collisions, rammings and groundings attribute a considerable percentage of marine casualties to poor ship controllability. A vessel's controllability is of a dichotomous nature, constrained not only by its inherent controllability characteristics, fixed by the naval architect, but also by the skill and the expertise of the shiphandler in initiating a conclusive control strategy. The results of an international survey of naval architects and shiphandlers are presented. The techniques of frequency distribution and factor analysis were used to identify the key ship controllability effectors. This survey highlights where improvements in terms of interface design can be made. The survey identifies the key controllability effectors of naval architects and ship-handlers for effective mariner-ship interaction. A case study is presented which identifies the applicability of part-task ship simulation to improve confidence levels in practical ship control. For effective mariner/ship interaction, the designers of ships must use the various codes of practice for a ship's bridge in order to improve the bridge as a control station, and marine licensing authorities have to realize the potential benefits that training with computerized ship simulation can bring the industry.
