Full textAbstract:
The complex influences of the East Australian Current (EAC) and winds on the waters of the continental shelf were addressed with a ship survey, moored and drifting instruments, satellite images and wind and sea level measurements. The study revealed intrusions of continental slope water reaching the inner continental shelf when the EAC was near the shelf edge and wind stress was near zero or upwelling favourable (northerly). The process was the onshore movement of a southward flowing stream of water originally from the continental slope. One event was captured near Cape Byron and Evans Head when these waters upwelled to the surface. When the wind stress turned northward, it reversed the inner shelf current and drove downwelling. Variations in the wind stress also modulated the strength of the EAC out across the shelf to the upper slope. The strength of the EAC per se varied with a time scale of 2–3 months; these variations decreased in amplitude westward until they were undetectable at the inner shelf. The EAC had a subsurface speed maximum of up to 1.6ms–1 at 100–150-m depth above the continental slope and was seen to accelerate with both time and distance southward along the 190-km length surveyed by the ship.

AbstractThe East Australian Current (EAC) is the complex and highly energetic poleward western boundary current of the South Pacific Ocean. A full-depth current meter and property (temperature and salinity) mooring array was deployed from the continental shelf to the abyssal waters off Brisbane Australia (27°S) for 18 months from April 2012 to August 2013. The EAC mooring array is an essential component of the Australian Integrated Marine Observing System (IMOS). During this period the EAC was coherent with an eddy kinetic to mean kinetic energy ratio of less than 1. The 18-month, mean, poleward-only mass transport above 2000 m is 22.1 ± 7.5 Sverdrups (Sv; 1 Sv ≡ 106 m3 s−1). The mean, poleward-only heat transport and flow-weighted temperature above 2000 m are −1.35 ± 0.42 PW and 15.33°C, respectively. A difference in the poleward-only and net poleward mass and heat transports above 2000 m of 6.3 Sv and 0.24 PW reflects the presence of an equatorward EAC retroflection at the eastern (offshore) end of the mooring array. A complex empirical orthogonal function (EOF) analysis of the along-slope velocity anomalies finds that the first two modes explain 72.1% of the velocity variance. Mode 1 is dominant at periods of approximately 60 days, and mode 2 is dominant at periods of 120 days. These dominant periods agree with previous studies in the Tasman Sea south of 27°S and suggest that variability of the EAC in the Tasman Sea may be linked to variability north of 27°S.

Full textAbstract:
For decades, the presence of a seasonal intrusion of the East Australian Current (EAC) has been disputed. In this study, with a Topographic Position Index (TPI)-based image processing technique, we use a 26-year satellite Sea Surface Temperature (SST) dataset to quantitatively map the EAC off northern New South Wales (NSW, Australia, 28–32°S and ~154°E). Our mapping products have enabled direct measurement (“distance” and “area”) of the EAC’s shoreward intrusion, and the results show that the EAC intrusion exhibits seasonal cycles, moving closer to the coast in austral summer than in winter. The maximum EAC-to-coast distance usually occurs during winter, ranging from 30 to 40 km. In contrast, the minimum distance usually occurs during summer, ranging from 15 to 25 km. Further spatial analyses indicate that the EAC undergoes a seasonal shift upstream of 29°40′S and seasonal widening downstream. This is the first time that the seasonality of the EAC intrusion has been confirmed by long-term remote-sensing observation. The findings provide new insights into seasonal upwelling and shelf circulation previously observed off the NSW coast.

Full textAbstract:
The Hawkesbury Bioregion located off southeastern Australia (31.5–34.5oS) is a region of highly variable circulation. The region spans the typical separation point of the East Australian Current (EAC), the western boundary current that dominates the flow along the coast of SE Australia. It lies adjacent to a known ocean warming hotspot in the Tasman Sea, and is a region of high productivity. However, we have limited understanding of the circulation, temperature regimes and shelf transport in this region, and the drivers of variability. We configure a high resolution (750m) numerical model for the Hawkesbury Shelf region nested inside 2 data assimilating models of decreasing resolution, to obtain the best estimate of the shelf circulation and transport over a 2-yr period (2012–2013). Here we show that the transport is driven by the mesoscale EAC circulation that strengthens in summer and is related to the separation of the EAC jet from the coast. Transport estimates show strong offshore export is a maximum between 32-33oS. Median offshore transports range 2.5–8.4Sv seasonally and are a maximum during in summer driven by the separation of the EAC jet from the coast. The transport is more variable downstream of the EAC separation, driven by the EAC eddy field. Onshore transport occurs more frequently off Sydney 33.5–34.5oS; seasonal medians range -1.7 to 2.3Sv, with an onshore maximum in winter. The region is biologically productive, and it is a known white shark nursery area despite the dominance of the oligotrophic western boundary current. Hence an understanding of the drivers of circulation and cross-shelf exchange is important.

Abstract. Understanding phytoplankton dynamics is critical across a range of topics, spanning from fishery management to climate change mitigation. It is particularly interesting in the East Australian Current (EAC) system, as the region's eddy field strongly conditions nutrient availability and therefore phytoplankton growth. Numerical models provide unparalleled insight into these biogeochemical dynamics. Yet, to date, modelling efforts off southeastern Australia have either targeted case studies (small spatial and temporal scales) or encompassed the whole EAC system but focused on climate change effects at the mesoscale (with a spatial resolution of 1/10∘). Here we couple a model of the pelagic nitrogen cycle (bio_Fennel) to a 10-year high-resolution (2.5–5 km horizontal) three-dimensional ocean model (ROMS) to resolve both regional and finer-scale biogeochemical processes occurring in the EAC system. We use several statistical metrics to compare the simulated surface chlorophyll to an ocean colour dataset (Copernicus-GlobColour) for the 2003–2011 period and show that the model can reproduce the observed phytoplankton surface patterns with a domain-wide RMSE of approximately 0.2 mg Chl a m−3 and a correlation coefficient of 0.76. This coupled configuration will provide a much-needed framework to examine phytoplankton variability in the EAC system providing insight into important ecosystem dynamics such as regional nutrient supply mechanisms and biogeochemical cycling occurring in EAC eddies.

AbstractWestern boundary currents (WBCs) are highly variable narrow meandering jets, making assessment of their volume transports a complex task. The required high-resolution temporal and spatial measurements are available only at a limited number of sites. In this study a method is developed for improving estimates of the East Australian Current (EAC) mean transport and its low-frequency variability, using complementary modern datasets. The present calculation is a case study that will be extended to other subtropical WBCs. The method developed in this work will reduce uncertainties in estimates of the WBC volume transport and in the interannual mass and heat budgets of the meridional overturning circulations, improving our understanding of the response of WBCs to local and remote forcing on long time scales. High-resolution expendable bathythermograph (HR-XBT) profiles collected along a transect crossing the EAC system near Brisbane, Australia, are merged with coexisting profiles and parking-depth trajectories from Argo floats, and with altimetric sea surface height data. Using HR-XBT/Argo/altimetry data combined with Argo trajectory-based velocities at 1000 m, the 2004–15 mean poleward alongshore transport of the EAC is 19.5 ± 2.0 Sv (1 Sv ≡ 106 m3 s−1) of which 2.5 ± 0.5 Sv recirculate equatorward just offshore of the EAC. These transport estimates are consistent in their mean and variability with concurrent and nearly collocated moored observations at 27°S, and with earlier moored observations along 30°S. Geostrophic transport anomalies in the EAC system, including the EAC recirculation, show a standard deviation of ±3.1 Sv at interannual time scales between 2004 and 2015.

Full textAbstract:
The in situ dataset used in the current study consists of the Pacific Current Meter 3 (PCM3) array, which was a significant part of the Australian contribution to the World Ocean Circulation Experiment to study the variability of the East Australian Current (EAC), and was operational between September 1991 and March 1994. Area-preserving spectral analysis has been used to investigate the typical time scales observed by the current meters. As a general rule, the spectra from the top layers of the shallow (1, 2 and 3) and the deep (4, 5 and 6) moorings have a distinct peak in the temporal mesoscale band (periods between 70 and 170 days), with a general redistribution of energy towards the higher-frequencies near the ocean floor. This peak has been linked with eddy variability of the EAC system, which influences the fluctuations of the current main jet. The vertical modes of the velocity profile show that the strong surface-intensified baroclinic signal of the EAC dominated the variability at mooring 4 location. Further offshore the predominant configuration resembles more closely the barotropic mode. Ultimately, spatial empirical orthogonal functions (EOF) analysis point out the impact of the presence/absence of the EAC jet in the array.

Full textAbstract:
Changes to the global climate are driving alterations to boundary current-influenced marine ecosystems. The diet of a pelagic teleost, Arripis trutta, was examined in the East Australian Current (EAC)-dominated coastal waters of southeastern (SE) Australia. The diet of A. trutta was dominated by pelagic baitfish, primarily Australian sardine (Sardinops sagax) and scads (Trachurus spp.). Diet varied substantially with both latitude and season linked to variability in the distribution and abundance of key prey species. An ontogenetic diet shift occurred, with crustaceans and polychaetes making up a large proportion of the diet of small fish compared with the dominance of baitfish at larger sizes. The diet of A. trutta has undergone a dramatic shift from one dominated by krill (Nyctiphanes australis) historically to baitfish today. This change is consistent with a well-documented regime shift caused by the increasing intensity of the EAC on coastal SE Australian waters. Understanding the temporal dynamics of this ecosystem is crucial for management of coastal fisheries and also for understanding the impacts of climate change on boundary current-dominated marine ecosystems worldwide.

Full textAbstract:
A numerical simulation of the East Australian Current (EAC) has been used to investigate the nutrification of shelf waters at Jervis Bay, south-eastern Australia, prior to the massive coccolithophorid bloom that was first observed on 16 December 1992. The simulation suggests that a small cold-core eddy developed between the continental slope at Jervis Bay and the EAC jet further offshore during 7 and 14 December 1992. This unstable cold-core eddy is likely to have uplifted cold, nutrient-rich water onto the Jervis Bay shelf, and this upwelling, in combination with upwelling-favourable winds, probably transported nutrients from the deep ocean to the entrance of the bay.

Full textAbstract:
Virus- and bacteriophage-induced mortality can have a significant impact on marine productivity and alter the flux of nutrients in marine microbial food-webs. Viral mediated horizontal gene transfer can also influence host fitness and community composition. However, there are very few studies of marine viral diversity in the Southern Hemisphere, which hampers our ability to fully understand the complex interplay of biotic and abiotic factors that shape microbial communities. We carried out the first genetic study of bacteriophage communities within a dynamic western boundary current (WBC) system, the east Australian current (EAC). Virus DNA sequences were extracted from 63 assembled metagenomes and six metaviromes obtained from various depths at 24 different locations. More than 1700 bacteriophage genomic fragments (>9 kbps) were recovered from the assembled sequences. Bacteriophage diversity displayed distinct depth and regional patterns. There were clear differences in the bacteriophage populations associated with the EAC and Tasman Sea euphotic zones, at both the taxonomic and functional level. In contrast, bathypelagic phages were similar across the two oceanic regions. These data provide the first characterisation of viral diversity across a dynamic western boundary current, which is an emerging model for studying the response of microbial communities to climate change.

The relatively understudied intermediate waters of the world have been implicated as an important part of the global ocean circulation. This thesis discusses the intermediate waters of the Pacific over space and time. Initially, by using geochemical tracers to look at the present distribution, sources and mixing of the water masses. Secondly, by using oxygen and carbon isotopes from sediment cores to study changes in Antarctic Intermediate Waters (AAIW) over the late Quaternary in the north Tasman Sea. The sediment cores also provide sedimentological data on the hemipelagic sedimentation in the Capricorn Channel in the southern Great Barrier Reef as well information on changes in the East Australian surface current (EAC) over the last glacial-interglacial transition.

Full textAbstract:
Parasitic wasps of the genus Scelio play an important role in the regulation of orthopteran populations and are implicated in suppressing numbers of numerous pest locusts and grasshoppers. This landmark volume provides a full taxonomic treatment of the sixty species of Scelio found on the Australian continent and reviews in detail the biology and ecology and host relationships of Scelio on a worldwide basis.
Taking an international perspective, the text outlines our current knowledge on topics such as host finding, population biology, and methods and techniques for collection and study in the field. The use of Scelio as biological control agents is discussed and comprehensive checklists document the recorded host relationships of each known species worldwide.
There is a full taxonomic revision of all Australian species of Scelio, half of which are newly described. Each species description is complemented with high-quality line drawings, micrographs and distribution maps. In addition, an illustrated key to species enables easy identification of species by non-taxonomists. Biology, Ecology and Systematics of Australian Scelio provides wasp taxonomists, researchers of orthoptera and biological control workers with a basis for detailed studies elsewhere on this economically important group of insects.

This book covers the implementation of telemental health (TMH) in resource-limited global settings. This book focuses on the current state of the technology, the different modalities, and the emergence of mobile-health. The global applicability, especially in resource-limited settings, is a new frontier for implementation sciences, and one that is proposed to reduce the mental health gap. The book reviews the global application of TMH internationally with examples from each continent. Case studies of TMH implementation from India, Taiwan, Africa, the Middle East, and more are layed out in this book. In addition, the book discusses provision of such care to underserved resource-limited populations globally, such as refugees in Denmark, Native Americans in the United States, and Aboriginal populations in Australia. This book promises a collective review of global TMH and hopes to provide anchorage for scholars and researches interested in this developing field.

Full textAbstract:
Ecology of Australian Temperate Reefs presents the current state of knowledge of the ecology of important elements of southern Australian sub-tidal reef flora and fauna, and the underlying ecological principles.
Preliminary chapters describe the geological origin, oceanography and biogeography of southern Australia, including the transitional temperate regions toward the Abrolhos Islands in the west and to Sydney in the east. The book then explains the origin and evolution of the flora and fauna at geological time scales as Australia separated from Antarctica; the oceanography of the region, including principal currents, and interactions with on-shelf waters; and the ecology of particular species or species groups at different trophic levels, starting with algae, then the ecological principles on which communities are organised. Finally, conservation and management issues are discussed.
Ecology of Australian Temperate Reefs is well illustrated with line drawings, figures and colour photographs showing the many species covered, and will be a much valued reference for biologists, undergraduates, and those interested and concerned with reef life and its natural history.

Full textAbstract:
The Dingo Debate explores the intriguing and relatively unknown story of Australia’s most controversial animal – the dingo. Throughout its existence, the dingo has been shaped by its interactions with human societies. With this as a central theme, the book traces the story of the dingo from its beginnings as a semi-domesticated wild dog in South-east Asia, to its current status as a wild Australian native animal under threat of extinction.
It describes how dingoes made their way to Australia, their subsequent relationship with Indigenous Australians, their successful adaption to the Australian landscape and their constant battle against the agricultural industry. During these events, the dingo has demonstrated an unparalleled intelligence and adaptable nature seen in few species. The book concludes with a discussion of what the future of the dingo in Australia might look like, what we can learn from our past relationship with dingoes and how this can help to allow a peaceful co-existence.
The Dingo Debate reveals the real dingo beneath the popular stereotypes, providing an account of the dingo’s behaviour, ecology, impacts and management according to scientific and scholarly evidence rather than hearsay. This book will appeal to anyone with an interest in Australian natural history, wild canids, and the relationship between humans and carnivores.

Full textAbstract:
Since European settlement of Australia began in 1788, drought has been viewed as a major natural threat. Despite warnings by scientists (e.g., Ratcliffe, 1947) and many public inquiries, government policies have, in the past, encouraged closer land settlement and intensification of cropping and grazing during wetter periods. Not surprisingly, drought forms part of the Australian psyche and has been well described in poetry, literature (e.g., Ker Conway, 1993), art, and the contemporary media (newspapers and television). Droughts have resulted in social, economic, and environmental losses. Attitudes toward drought in Australia are changing. Government policies now consider drought to be part of the natural variability of rainfall and acknowledge that drought should be better managed both by governments and by primary producers. Nonetheless, each drought serves as a reminder of the difficult challenges facing primary producers during such times. We begin this chapter with a brief overview of drought in Australia and its impacts on agricultural production, the environment, rural communities, and the national economy. We outline some of the ways governments and primary producers plan for and respond to drought and describe in detail an operational national drought alert system. Australia has mainly an arid or semiarid climate. Only 22% of the country has rainfall in excess of 600mmper annum, confined to coastal areas to the north, east, southeast, and far southwest of the country (http://www.bom.gov.au/climate/ahead/soirain.shtml). Australia also has high year-to-year and decade-to-decade variation in rainfall due, in part, to the influence of the El Niño/Southern Oscillation (ENSO) phenomenon (http://www.bom.gov.au/climate/ahead/soirain.shtml). The Interdecadal Pacific Oscillation (IPO) also contributes to the rainfall variability at annual and decadal scales and modulates ENSO impacts on rainfall (Power et al., 1999). The current geographic boundaries of agricultural production were reached in the late 19th century, and the entire agricultural region has experienced drought, in some form, over the past 100 years. Protracted dry periods occurred during the period from late 1890s to 1902 in eastern Australia, during the mid to late 1920s and 1930s over most of the continent, during the 1940s in eastern Australia, during the 1960s over central and eastern Australia, and during 1991–95 in parts of central and northeastern Australia.

The rapidly increased use of Information and Communications Technologies (ICTs) has increased demand for electronic equipment such as mobile phones and computers. Individuals and government institutions worldwide are adopting ICTs at a fast pace. Increased consumption has resulted in huge amounts of e-Waste generated from scrapped electronics. E-Waste contains chemical substances that have adverse effects on the environment and human health. Consequently, handling of e-Waste needs to be organized in ways that minimize the adverse effects. This chapter investigates how the East African Community (EAC) governments, i.e., Kenya, Uganda, Tanzania, Rwanda, and Burundi, conceive their role in combating negative impact of e-Waste and how their views and current actions compare to the current state of the art practices in e-Waste management. As data on e-Waste handling in EAC countries is not publicly available, semi-structured interviews with high government officials and a literature review were conducted. The results show that EAC governments consider e-Waste to be an emerging problem. Despite this awareness and attempts to mitigate the problem in some of the countries, there are currently no solid solutions that have been crafted to rectify or mitigate this problem. The study suggests practical solutions for resolving e-Waste challenges in EAC.

The chapter outlines the design of a game to raise nutritional awareness within primary school-aged children. The game uses a blend of simulated and pervasive elements using ubiquitous technologies to enhance children’s capacity to make informed choices with regard to their own eating habits. Nute’s Adventures in Nomland is a project currently being undertaken at an Australian university to explore the potential of a casual game can be used to help parents and children understand the different nutritional values of the food they eat. The game contains both pervasive and simulation elements. The pervasive nature of the game is evident in the use of mobile phones to scan nutrition labels as part of a shopping activity. This shopping is then brought into a simulation game that allows learners to explore the effects of their decisions on a virtual pet, Nute, and then identify strategies to address shortfalls in that decision-making.

Such systems have seen a phenomenal growth in the last decade in the US, Europe and Australian markets. With the recent upturn in South-East Asian economies, an increase in demand for ERP systems is expected and opportunities clearly exist for provision of high-quality ERP education programs in this region. This paper describes the issues and barriers associated with integrating ERP systems into university curricula. It outlines the experiences of Victoria University in offering ERP education through a strategic alliance with SAP. The University is extending its offshore programs by incorporating ERP education to take advantage of the current increase in demand of ERP employment opportunities in the South-East Asian The proposed ERP eLearning Model incorporates four different technologies for the delivery of ERP education into the Asian region via the internet. Each technological solution is discussed and advantages identified.

ABSTRACT Energy is one of the key drivers of economic growth and development world over. Overcoming energy poverty is one of world's great challenges. All the countries in the East African Region (EAR) are not producing sufficient energy to meet their current needs. The energy mix in the EAR currently includes hydroelectric power, geothermal energy, solar, biomass and fossil fuels. The region's petroleum products consumption, the entire volume of which is currently imported, is estimated at 180,000 bbl/day and is growing at between 4 – 6% p.a. It is projected that the region will consume about 400,000bbl/day by 2030. The discovery of commercially viable oil and gas deposits in Uganda, Kenya, Tanzania and Democratic Republic of Congo however, marks a great opportunity to turn around the rather bleak state of the energy sector in the region. These resources however remain largely untapped due to lack of the necessary infrastructure such as road networks, upstream facilities, refinery, pipelines, and gas processing facilities, that are necessary to access, store, process and transport these resources. A number of countries in the EAR are planning for the development of such key infrastructure to enable the commercialization of the discovered these resources. The EAR needs to harmonise the planning and development of petroleum infrastructure in order to leverage the power of collaborative action to attract investment and ensure optimal development of this infrastructure. A case in point is Uganda which plans to commercialise its discovered oil and gas resources, estimated at 6.5 billion barrels as of 2016, through the development of an oil refinery, a crude oil export pipeline and power generation. These projects are being developed with joint participation of the East African Community (EAC) Partner States. Uganda estimates to spend over USD 10 billion on oil and gas infrastructure in the next five years. The region needs to provide a conducive investment environment in order to attract financing for these projects. This can be achieved through providing incentives such as attractive taxation regimes, streamlined decision making and security, among others, given the high CAPEX investments. Given that background, this paper will; Assess the current status of the oil and gas infrastructure in the region vis a vis the growing energy needsDiscuss the optimal infrastructure requirements for the successful development of the oil and gas industry in order to meet the region's growing energy needs.Highlight the investment requirements, incentives, challenges and financing options for the planned refinery in Uganda.

Abstract Multilateral wells have been proven over decades and have developed into a reliable and cost effective approach to mature field rejuvenation and extended commercial viability. This paper will discuss case studies demonstrating a number of techniques used to create infill multilateral wells in existing fields with a high level of reliability and repeatability. Techniques reviewed will cover cutting and pulling production casing to drill and case a new mainbore versus sidetracking and adding laterals to an existing mainbore. Discussion will also cover completion designs that tie new laterals into existing production casing providing significantly greater reservoir contact. Temporary isolation of high water-cut laterals brought into production later in the well's life through bespoke completion designs will also be discussed. Case studies will include discussion of workover operations, isolation methods, and lateral creation systems. Where available, resulting field performance improvements will also be discussed. In Norway, slot recoveries are commonly performed by cutting and pulling the 10-3/4" casing, redrilling a new mainbore, and running new casing. This enables junction placement closer to unswept zones and easier lateral drilling to targets. It does have drawbacks, however, related to the additional time required to pull the subsea xmas tree and challenges associated with pulling casing. In 2019, Norway successfully completed a 10-3/4" retrofit installation, whereas a sidetrack was made from the 10-3/4" and an 8-5/8" expandable liner was run down into the reservoir pay zone where two new laterals were created. The 8-5/8" liner saved time otherwise spent having to drill the section down to the payzone from the laterals. These wells have a TAML Level 5 isolated junction, Autonomous Inflow Control Devices (AICDs) in each lateral, and an intelligent completion interface across the junction, enabling active flow management and monitoring of both branches. In Asia, infill laterals were added to existing wellbores by sidetracking 9-5/8" casing and tying production back to the original mainbore. These dual laterals were completed with intelligent completions to enable lateral flow management and monitoring of both laterals. In Australia, dual laterals were created in a similar fashion; laterals are added to existing wells; however, a novel approach was used to manage water from existing lower mainbore laterals whereby they are shut in at completion and opened later when the new lateral is watered out. The older lateral now produces at lower water cut given the time allowed for water coning in the lateral to relax. Using this practice, production is alternated back and forth between the two laterals. In the Middle East, an older well has been converted from TAML Level 4 to Level 5 in order to prevent detected gas migrating into the mainbore at the junction. This conversion of a cemented junction well has enabled production to resume on this well. The well was converted to incorporate an intelligent completion to enable flow control of each lateral. This paper intends to provide insights into the various mature field re-entry methods for multilateral well construction, and a review of the current technology capabilities and well designs through the review of multiple case histories.
