Abstract:
Researchers use transcriptomics analyses for biological data mining, interpretation, and presentation. Galaxy-based tools are utilized to analyze various complex disease transcriptomic data to understand the pathogenesis of the disease, which are user-friendly. This work provides simple methods for differential expression analysis and analysis of these results in gene ontology and pathway enrichment tools like David, WebGestalt. This method is very effective in better analysis and understanding the transcriptomic data. Transcriptomics analysis has been made on rheumatoid arthritis sra data. Rheumatoid arthritis (RA) is a systemic autoimmune disease. T cells and autoantibodies mediate the pathogenesis. This article discusses the genes which are differentially expressed between the healthy (n=50) and diseased (n=51) and the functions of those genes in the pathogenesis of RA.

Abstract:
Abstract Recent high-throughput sequencing endeavors have yielded multigene/protein phylogenies that confidently resolve several inter- and intra-class relationships within the phylum Ciliophora. We leverage the massive sequencing efforts from the Marine Microbial Eukaryote Transcriptome Sequencing Project, other SRA submissions, and available genome data with our own sequencing efforts to determine the phylogenetic position of Mesodinium and to generate the most taxonomically rich phylogenomic ciliate tree to date. Regardless of the data mining strategy, the multiprotein data set, or the molecular models of evolution employed, we consistently recovered the same well-supported relationships among ciliate classes, confirming many of the higher-level relationships previously identified. Mesodinium always formed a monophyletic group with members of the Litostomatea, with mixotrophic species of Mesodinium—M. rubrum, M. major, and M. chamaeleon—being more closely related to each other than to the heterotrophic member, M. pulex. The well-supported position of Mesodinium as sister to other litostomes contrasts with previous molecular analyses including those from phylogenomic studies that exploited the same transcriptomic databases. These topological discrepancies illustrate the need for caution when mining mixed-species transcriptomes and indicate that identifying ciliate sequences among prey contamination—particularly for Mesodinium species where expression from stolen prey nuclei appears to dominate—requires thorough and iterative vetting with phylogenies that incorporate sequences from a large outgroup of prey.

Abstract:
Abstract Metagenomics became a standard strategy to comprehend the functional potential of microbial communities, including the human microbiome. Currently, the number of metagenomes in public repositories is increasing exponentially. The Sequence Read Archive (SRA) and the MG-RAST are the two main repositories for metagenomic data. These databases allow scientists to reanalyze samples and explore new hypotheses. However, mining samples from them can be a limiting factor, since the metadata available in these repositories is often misannotated, misleading, and decentralized, creating an overly complex environment for sample reanalysis. The main goal of the HumanMetagenomeDB is to simplify the identification and use of public human metagenomes of interest. HumanMetagenomeDB version 1.0 contains metadata of 69 822 metagenomes. We standardized 203 attributes, based on standardized ontologies, describing host characteristics (e.g. sex, age and body mass index), diagnosis information (e.g. cancer, Crohn's disease and Parkinson), location (e.g. country, longitude and latitude), sampling site (e.g. gut, lung and skin) and sequencing attributes (e.g. sequencing platform, average length and sequence quality). Further, HumanMetagenomeDB version 1.0 metagenomes encompass 58 countries, 9 main sample sites (i.e. body parts), 58 diagnoses and multiple ages, ranging from just born to 91 years old. The HumanMetagenomeDB is publicly available at https://webapp.ufz.de/hmgdb/.

Abstract:
The advent of Next Generation Sequencing has reduced sequencing costs and increased genomic projects from a huge amount of organismal taxa, generating an unprecedented amount of genomic datasets publicly available. Often, only a tiny fraction of outstanding relevance of the genomic data produced by researchers is used in their works. This fact allows the data generated to be recycled in further projects worldwide. The assembly of complete mitogenomes is frequently overlooked though it is useful to understand evolutionary relationships among taxa, especially those presenting poor mtDNA sampling at the level of genera and families. This is exactly the case for ants (Hymenoptera:Formicidae) and more specifically for the subfamily Pseudomyrmecinae, a group of arboreal ants with several cases of convergent coevolution without any complete mitochondrial sequence available. In this work, we assembled, annotated and performed comparative genomics analyses of 14 new complete mitochondria from Pseudomyrmecinae species relying solely on public datasets available from the Sequence Read Archive (SRA). We used all complete mitogenomes available for ants to study the gene order conservation and also to generate two phylogenetic trees using both (i) concatenated set of 13 mitochondrial genes and (ii) the whole mitochondrial sequences. Even though the tree topologies diverged subtly from each other (and from previous studies), our results confirm several known relationships and generate new evidences for sister clade classification inside Pseudomyrmecinae clade. We also performed a synteny analysis for Formicidae and identified possible sites in which nucleotidic insertions happened in mitogenomes of pseudomyrmecine ants. Using a data mining/bioinformatics approach, the current work increased the number of complete mitochondrial genomes available for ants from 15 to 29, demonstrating the unique potential of public databases for mitogenomics studies. The wide applications of mitogenomes in research and presence of mitochondrial data in different public dataset types makes the “no budget mitogenomics” approach ideal for comprehensive molecular studies, especially for subsampled taxa.

Abstract:
Using primary and secondary historical data, descriptive time-series data, and site observations, this study unpacks the developmental history of one of the United States' oldest, largest, and still working fisheries. This study uses narrative analysis to explore how processes of commodification and the institutional workings of capitalist food regimes drove specific developmental outcomes. Internal comparison across periods enables an analysis of why the fishery declined in recent decades. The case also reveals important dynamics of the capitalist world food system and demonstrates how intersectional considerations, particularly the intersection of race and class dynamics, can bolster the “tragedy of the commodity” theoretical framework. The study thus tests and expands on that framework by including the considerations of cross-cutting inequalities and the world food system. Overall, this study demonstrates how the demands of generalized commodity production, in conjunction with the institutional parameters of a world capitalist food system, link processes of development across terrestrial and aquatic food systems. Furthermore, the internal comparison elucidates the socio-structural factors that drove the severe decline of the 170-year-old Atlantic menhaden fishery.

Abstract:
Deep-sea polymetallic nodules are a mineral resource with potential for commercial development. Due to the unique deep-sea environment in which they are found, specialized technology and equipment are required for their extraction. In this paper, firstly, the development of deep-sea polymetallic nodule mining technology is classified into three stages, and its characteristics are summarized. Moreover, the results from research into deep-sea polymetallic nodule mining technology are analyzed, including proposals for mining systems, research into key technologies, basic scientific problems, and proof of technical feasibility from sea tests. Secondly, the testing of the collector prototype and the environmental impact assessment study of Global Sea Mineral Resources NV, as well as the progress of the deep-sea polymetallic nodule mining test project in China, are introduced. On this basis, the opportunities and challenges brought by the fast-growing demand for electric vehicles to the development of deep-sea polymetallic mining technology is analyzed, and a possible technical scheme for a mining system and the trends in its development towards high reliability and high standards of environmental protection according to the requirements of commercial exploitation are explored. This provides a reference for the research and development of high-efficiency technology and equipment for the mining of deep-sea polymetallic nodules.

Abstract:
The lack of law enforcement related to sea sand mining activities that conflict with the community in Lampung Province certainly causes many problems. In addition, the impact of the sea sand mining permit also overlaps the allocation of coastal areas and small islands and has the potential to cause quite a high social conflict and environmental ecosystems and cause of ecological disasters. This article aims to analyze law enforcement against marine sand mining activities that conflict with the community in Lampung Province. This study uses normative and empirical juridical methods with a qualitative analysis model. The results showed that sea sand mining conflicts in Lampung Province occurred due to the processes of issuing sea sand mining permits that overlapped with the fishing zones. Also in Lampung Provincial Regulation No. 1 of 2018 concerning Zoning Plans for Coastal Areas and Small Islands, there is no space allocation for the issuance of sea sand mining permits from 12 miles of coastline except for oil and gas mining in the East Lampung waters, complex conflicts due to enforcement The sea sand mining law is not clear, as evidenced by the existence of several cases of violations in the coastal sector and small islands of Lampung Province which were left without going through legal processes and imposition of sanctions.

Deep-sea mining activities are expected to commence in the next decade; the International Seabed Authority (ISA) has already issued twenty nine exploration licenses for polymetallic nodules, polymetallic sulphides and polymetallic crusts. The ISA is seeking to approve the exploitation regulations for polymetallic nodules in the next two years, but there are significant research and knowledge gaps that still have to be explored. The discharge of dewatering plumes, the analysis of the effect of vortex-induced vibrations (VIV) on mining risers, and the development of updated and detailed economic models -which are among the most pressing ones - are addressed in this thesis. PLUMEX field studies were conducted in the Pacific Ocean to create and monitor six dewatering plumes. The data obtained from the experiments will be used to validate analytic and numeric plume models that will help to assess the environmental impacts. Additionally, a preliminary VIV analysis of a simple riser configuration was conducted to show the significant impact of VIV on the fatigue life. The results showed that the fatigue life could be reduced to less than one year. Lastly, an independent and thorough economic model is being developed at MIT to allow the simulation of different scenarios and forecast the economic result of a polymetallic nodule exploitation. The ISA will consider the results from the model to determine the royalties and fees that will be paid by future contractors in order to share their benefit with the humankind.

Abstract:
Structure Activity Relationship (SAR) modelling capitalises on techniques developed within the computer science community, particularly in the fields of machine learning and data mining. These machine learning approaches are often developed for the optimisation of model accuracy which can come at the expense of the interpretation of the prediction. Highly predictive models should be the goal of any modeller, however, the intended users of the model and all factors relating to usage of the model should be considered. One such aspect is the clarity, understanding and explanation for the prediction. In some cases black box models which do not provide an interpretation can be disregarded regardless of their predictive accuracy. In this thesis the problem of model interpretation has been tackled in the context of models to predict toxicity of drug like molecules. Firstly a novel algorithm has been developed for the interpretation of binary classification models where the endpoint meets defined criteria: activity is caused by the presence of a feature and inactivity by the lack of an activating feature or the deactivation of all such activating features. This algorithm has been shown to provide a meaningful interpretation of the model’s cause(s) of both active and inactive predictions for two toxicological endpoints: mutagenicity and skin irritation. The algorithm shows benefits over other interpretation algorithms in its ability to not only identify the causes of activity mapped to fragments and physicochemical descriptors but also in its ability to account for combinatorial effects of the descriptors. The interpretation is presented to the user in the form of the impact of features and can be visualised as a concise summary or in a hierarchical network detailing the full elucidation of the models behaviour for a particular query compound. The interpretation output has been capitalised on and incorporated into a knowledge mining strategy. The knowledge mining is able to extract the learned structure activity relationship trends from a model such as a Random Forest, decision tree, k Nearest Neighbour or support vector machine. These trends can be presented to the user focused around the feature responsible for the assessment such as ACTIVATING or DEACTIVATING. Supporting examples are provided along with an estimation of the models predictive performance for a given SAR trend. Both the interpretation and knowledge mining has been applied to models built for the prediction of Ames mutagenicity and skin irritation. The performance of the developed models is strong and comparable to both academic and commercial predictors for these two toxicological activities.

The dissertation presents the work done under the scope of the NP7 Self-Learning project regarding the design and development of the Adapter component as a foundation for the Self-Learning Production Systems (SLPS). This component is responsible to confer additional proprieties to production systems such as lifecycle learning, optimization of process parameters and, above all, adaptation to different production contexts. Therefore, the SLPS will be an evolvable system capable to self-adapt and learn in response to dynamic contextual changes in manufacturing production process in which it operates. The key assumption is that a deeper use of data mining and machine learning techniques to process the huge amount of data generated during the production activities will allow adaptation and enhancement of control and other manufacturing production activities such as energy use optimization and maintenance. In this scenario, the SLPS Adapter acts as a doer and is responsible for dynamically adapting the manufacturing production system parameters according to changing manufacturing production contexts and, most important, according to the history of the manufacturing production process acquired during SLPS run time.To do this, a Learning Module has been also developed and embedded into the SLPS Adapter. The SLPS Learning Module represents the processing unit of the SLPS Adapter and is responsible to deliver Self-learning capabilities relying on data mining and operator’s feedback to up-date the execution of adaptation and context extraction at run time. The designed and implemented SLPS Adapter architecture is assessed and validated into several application scenario provided by three industrial partners to assure industrial relevant self-learning production systems. Experimental results derived by the application of the SLPS prototype into real industrial environment are also presented.

Resumo: Foram sintetizadas sílicas mesoporosas híbridas a partir da funcionalização da SBA-15 e filossilicatos de cobalto e níquel com macrociclos orgânicos contendo sítios básicos para a sorção dos íons metálicos tóxicos Pb, Cd e Cu. A SBA-15 e o filossilicatos de magnésio também foram modificados com cadeias orgânicas contendo diferentes quantidades de átomos de enxofre para serem aplicados na sorção de íons complexos de ouro e de metais do grupo da platina com o intuito de otimizar as condições adotadas para a extração destes metais preciosos de seus minérios. Os materiais contendo macrociclos orgânicos foram formados a partir de sucessivas reações nas superfícies com diferentes moléculas orgânicas para conter os centros básicos nitrogênio, oxigênio e enxofre. As técnicas de caracterização confirmaram as formações das estruturas mesoporosas e lamelares, mostrando a presença de cadeias orgânicas pendentes contendo os grupos funcionais de interesse. Os híbridos funcionalizados com macrociclos apresentaram-se efetivos nas sorções dos metais tóxicos, com alta capacidade para o íon Pb quando estão funcionalizados com macrociclos contendo enxofre. Enquanto que, no geral, as capacidades de sorção de todos os materiais tornaram-se maiores com o aumento das quantidades de centros básicos. Estas capacidades de sorção ainda sofrem um aumento após a formação dos macrociclos. As sorções dos complexos de metais preciosos foram efetivas em todos os casos, com destaque para tetracloroaurato e tetracloropaladato, que apresentaram altos valores de sorção. Ótimos valores também foram obtidos na sorção do complexo aurotiossulfato com o filossilicato de magnésio funcionalizado com grupos tiol. As titulações calorimétricas dos metais tóxicos com as matrizes contendo macrociclos orgânicos indicaram processos favoráveis de interação dos sítios básicos com os cátions em solução aquosa, devido a valores negativos de energia de Gibbs, em um processo espontâneo, e valores positivos de entropia. Os valores de entalpia mostram que todas as interações metais/centros básicos na interface sólido/líquido são exotérmicas
Abstract: This thesis reports the syntheses of hybrid mesoporous sílicas, through the functionalization of SBA-15, and cobalt and nickel phyllosilicates functionalized with organic macrocycles containing basic sites for the sorption of the toxic metallic ions Pb, Cd and Cu. SBA-15 and magnesium phyllosilicates were also modified with organic chains containing different amounts of sulfur atoms to be applied to the sorption of complex ions of gold and platinum group metals. This is done in the aim of optimizing the conditions adopted in the extraction of these precious metals from their ores. The materials with pendant organic macrocycles were formed through successive reactions on the surfaces with different organic molecules possessing nitrogen, oxygen and sulfur basic centers. The characterization techniques confirmed the formation of mesoporous and layered structures, showing the presence of pendant organic chains with the desired functional groups. The hybrids functionalized with macrocycles were effective in the sorption of toxic metals, with high sorption capacities for Pb when the solids are functionalized with macrocycles containing sulfur atoms. Whereas the sorption capacities of all materials were improved with the increase of basic centers amounts. These sorption capacities were even improved after the macrocycles formation. The sorption of precious metals complexes were effective in all cases, especially for tetrachloroaurate and tetrachloropalladate, which presented high sorption values. Exceptional values were also acquired in the sorption of aurothiosulfate complex by the magnesium phyllosilicate functionalized with thiol groups. The calorimetric titrations of toxic metals with the matrices containing organic macrocycles indicated favorable processes for the interaction between the basic centers and the cations in aqueous solution, due to negative values of Gibbs energy, in a spontaneous process. The results also indicated positive values of entropy. The values of enthalpy showed that all the metal/basic centers interactions at the solid/liquid interface are exothermic

Abstract:
As much as 80% of all data is unstructured but still has exploitable information available. For example, unstructured text data could result from comment fields in surveys or incident reports. You want to explore this unstructured text to better understand the information that it contains. Text Mining, based on a transformation of free text into numerical summaries, can pave the way for new findings. This example of the new text mining feature in JMP starts with a multi-step text preparation using techniques like stemming and tokenizing. This data curation is pivotal for the subsequent analysis phase, exploring data clusters and semantics. Finally, combining text mining results with other structured data takes familiar multivariate analysis and predictive modeling to a next level.

Abstract:
This paper discusses the state of the art of deep sea mining technology in China. The research and development of deep sea mining technology in China started from the polymetallic nodules mining. A pilot mining system, which consists of a self-propelled collector, hydraulic pipe lift and a surface vessel, has been developed. In 2001, a lake mining trial was conducted in the pilot system, through which artificial nodules lying on the floor of lake were collected by the collector and then transported up to the surface vessel by a flexible hose subsystem. The lake mining trial confirmed the maneuverability and controllability of the self-propelled collector, the efficiency of the hydraulic pick-up device, and the feasibility of lifting system with flexible hose. In addition, some research has been conducted on the cobalt-rich ferromanganese crusts mining techniques such as the methods of in situ fragmentation and separation of crusts from the substrate rock, and the technique of crust mining using the robotic seabed vehicles. During the past decade, China has enhanced the research on key techniques of deep sea mining system. Some new laboratories and facilities have been constructed, including a miner test laboratory with a 50 mx50 mx5 m basin, a lifting test setup which can carry out circular lifting test and one way transporting test, and a computer simulation research laboratory which can partially test some boundary conditions and demonstrate simulation results. China has further planned to investigate the techniques of deep sea mining for polymetallic sulphide, to develop the facilities for the application, and to assess the economic feasibility of the deep sea mining development. We will continue to explore the new deep sea mining methods and technologies.

Abstract:
Deep-sea mining has been a subject of interest for several groups and countries for over four decades, due to its potential for the economic recovery of large reserves of minerals that would provide an alternative resource of strategic metals for industrial development. A deep-sea mining operation will offer a variety of challenges, owing to deep-sea mineral occurrences, extreme physical and chemical conditions and unknown environmental settings. Owing to growing concern for the environmental impact of deep-sea mining, multi-disciplinary environmental studies have been progressive in many countries. The historic approaches in the world are summarized. The important role of quantified environmental assessment for deep-sea mining is introduced. Some efforts necessary for keeping benthic habitat safe and sustainable in the coming commercial mining phases are discussed.

Abstract:
Experience in the area of wet mining and the dredging industry learns that the excavation system cannot be seen separate from the slurry transportation system. These two key systems in a deep sea mining operation interrelate to such extend that they must be developed towards an integral solution. The nominal production, peak production and variability of these figures must match for all sub-systems in the overall mining system to optimize for mining efficiency; we call this the ‘game of capacities’. Also the configuration of the excavation and transport system has great consequences. For instance an important question is whether to place the first pump and its drive of the slurry transport system on the seafloor mining tool or in the riser system. The choices made impact amongst others on; the mining tool’s reach (and thus efficiency), the seafloor mining tool’s propulsion system and its geo-mechanical interaction, the slurry transport flow and pumping power requirements. This paper will discuss the several dependencies of the (producing) subsystems and important choices for configuration and their consequences regarding technology, capex, opex, reliability and maintainability.

Abstract:
Successful mining of deep sea deposits strongly depends on the proper choice of the right equipment. The most probable concept for a deep sea mining system would consist of the three major sub-components: Seafloor Mining Tool, Vertical Transport System and Mining Support Vessel. In this paper, emphasis is placed on the Vertical Transport System. We analyse the pros and cons of the different concepts such as hydraulic transport using centrifugal or positive-displacement slurry pumps, conventional and unconventional airlift systems, vertical offshore mining systems and vortex slurry transportation systems. All these systems are considered for their applicability at different water depths (from the relatively shallow to the relatively deep) for the different types of materials (from the relatively fine to the relatively coarse) and various production rates in terms of the efficiency, reliability and state of the art of technology.

Abstract:
In the Soviet era in Ukraine, theoretical subjects dominated in the education curriculum. Since independence, there have been profound changes in the higher education system of Ukraine. The system has adapted to the market model, with an increasing number of applied disciplines such as data mining, software engineering and data visualization. Courses should cover both theoretical knowledge and practical skills. Recently, one of the top requested areas at the information technology market is the processing of large data sets (Big data). Many leading universities of Ukraine, including Taras Shevchenko National University of Kyiv and Kyiv-Mohyla Academy, plan to establish courses of data mining, statistics, and data visualization. For now, however, universities do not have enough teachers. Therefore, under the scope of the Ukrainian Distance Education Project "Prometheus", in 2017 an online course on the Big Data will be launched. This paper will summarize the curriculum developed by the authors, in courses on Business Analytics, Software Engineering, Data Analysis, and Data Visualization.

Abstract:
The AL561 cruise was conducted in the framework of the project APOC (“Anthropogenic impacts on Particulate Organic Carbon cycling in the North Sea”). This collaborative project between GEOMAR, AWI, HEREON, UHH, and BUND is to understand how particulate organic carbon (POC) cycling contributes to carbon sequestration in the North Sea and how this ecosystem service is compromised and interlinked with global change and a range of human pressures include fisheries (pelagic fisheries, bottom trawling), resource extraction (sand mining), sediment management (dredging and disposal of dredged sediments) and eutrophication. The main aim of the sampling activity during AL561 cruise was to recover undisturbed sediment from high accumulation sites in the Skagerrak/Kattegat and to subsample sediment/porewater at high resolution in order to investigate sedimentation transport processes, origin of sediment/POC and mineralization processes over the last 100- 200 years. Moreover, the actual processes of sedimentation and POC degradation in the water column and benthic layer will be addressed by sampling with CTD and Lander devices. In total 9 hydroacoustic surveys (59 profiles), 4 Gravity Corer, 7 Multicorer, 3 Lander and 4 CTD stations were successfully conducted during the AL561 cruise. - (Alkor-Berichte ; AL561)

Paynter, Robin A., Celia Fiordalisi, Elizabeth Stoeger, Eileen Erinoff, Robin Featherstone, Christiane Voisin, and Gaelen P. Adam. A Prospective Comparison of Evidence Synthesis Search Strategies Developed With and Without Text-Mining Tools. Agency for Healthcare Research and Quality (AHRQ), March 2021. http://dx.doi.org/10.23970/ahrqepcmethodsprospectivecomparison.

Full text
Abstract:
Background: In an era of explosive growth in biomedical evidence, improving systematic review (SR) search processes is increasingly critical. Text-mining tools (TMTs) are a potentially powerful resource to improve and streamline search strategy development. Two types of TMTs are especially of interest to searchers: word frequency (useful for identifying most used keyword terms, e.g., PubReminer) and clustering (visualizing common themes, e.g., Carrot2). Objectives: The objectives of this study were to compare the benefits and trade-offs of searches with and without the use of TMTs for evidence synthesis products in real world settings. Specific questions included: (1) Do TMTs decrease the time spent developing search strategies? (2) How do TMTs affect the sensitivity and yield of searches? (3) Do TMTs identify groups of records that can be safely excluded in the search evaluation step? (4) Does the complexity of a systematic review topic affect TMT performance? In addition to quantitative data, we collected librarians' comments on their experiences using TMTs to explore when and how these new tools may be useful in systematic review search¬¬ creation. Methods: In this prospective comparative study, we included seven SR projects, and classified them into simple or complex topics. The project librarian used conventional “usual practice” (UP) methods to create the MEDLINE search strategy, while a paired TMT librarian simultaneously and independently created a search strategy using a variety of TMTs. TMT librarians could choose one or more freely available TMTs per category from a pre-selected list in each of three categories: (1) keyword/phrase tools: AntConc, PubReMiner; (2) subject term tools: MeSH on Demand, PubReMiner, Yale MeSH Analyzer; and (3) strategy evaluation tools: Carrot2, VOSviewer. We collected results from both MEDLINE searches (with and without TMTs), coded every citation’s origin (UP or TMT respectively), deduplicated them, and then sent the citation library to the review team for screening. When the draft report was submitted, we used the final list of included citations to calculate the sensitivity, precision, and number-needed-to-read for each search (with and without TMTs). Separately, we tracked the time spent on various aspects of search creation by each librarian. Simple and complex topics were analyzed separately to provide insight into whether TMTs could be more useful for one type of topic or another. Results: Across all reviews, UP searches seemed to perform better than TMT, but because of the small sample size, none of these differences was statistically significant. UP searches were slightly more sensitive (92% [95% confidence intervals (CI) 85–99%]) than TMT searches (84.9% [95% CI 74.4–95.4%]). The mean number-needed-to-read was 83 (SD 34) for UP and 90 (SD 68) for TMT. Keyword and subject term development using TMTs generally took less time than those developed using UP alone. The average total time was 12 hours (SD 8) to create a complete search strategy by UP librarians, and 5 hours (SD 2) for the TMT librarians. TMTs neither affected search evaluation time nor improved identification of exclusion concepts (irrelevant records) that can be safely removed from the search set. Conclusion: Across all reviews but one, TMT searches were less sensitive than UP searches. For simple SR topics (i.e., single indication–single drug), TMT searches were slightly less sensitive, but reduced time spent in search design. For complex SR topics (e.g., multicomponent interventions), TMT searches were less sensitive than UP searches; nevertheless, in complex reviews, they identified unique eligible citations not found by the UP searches. TMT searches also reduced time spent in search strategy development. For all evidence synthesis types, TMT searches may be more efficient in reviews where comprehensiveness is not paramount, or as an adjunct to UP for evidence syntheses, because they can identify unique includable citations. If TMTs were easier to learn and use, their utility would be increased.

Abstract:
Cruise SO268 is fully integrated into the second phase of the European collaborative JPI-Oceans project MiningImpact and is designed to assess the environmental impacts of deep-sea mining of polymetallic nodules in the Clarion-Clipperton Fracture Zone (CCZ). In particular, the cruise aimed at conducting an independent scientific monitoring of the first industrial test of a pre-protoype nodule collector by the Belgian company DEME-GSR. The work includes collecting the required baseline data in the designated trial and reference sites in the Belgian and German contract areas, a quantification of the spatial and temporal spread of the produced sediment plume during the trials as well as a first assessment of the generated environmental impacts. However, during SO268 Leg 1 DEME-GSR informed us that the collector trials would not take place as scheduled due to unresolvable technical problems. Thus, we adjusted our work plan accordingly by implementing our backup plan. This involved conducting a small-scale sediment plume experiment with a small chain dredge to quantify the spatial and temporal dispersal of the suspended sediment particles, their concentration in the plume as well as the spatial footprint and thickness of the deposited sediment blanket on the seabed.

Abstract:
This open file reports geochemical data for stream and groundwater samples collected around the Casino porphyry Cu-Au-Mo deposit, one of the largest and highest-grade deposits of its kind in Canada. The calc-alkaline porphyry is hosted in a Late Cretaceous quartz monzonite and associated breccias in the unglaciated region of west central Yukon. Water chemistry around the deposit was investigated because: (i) the deposit has not yet been disturbed by mining; (ii) the deposit was known to have metal-rich waters in local streams; and (iii) the deposit has atypically preserved ore zones. Stream water samples were collected at 22 sites and groundwater samples were collected from eight sites. Surface and groundwaters around the Casino deposit are anomalous with respect to Cd (up to 5.4 µg/L), Co (up to 64 µg/L), Cu (up to 1657 µg/L), Mo (up to 25 µg/L), As (up to 17 µg/L), Re (up to 0.7 µg/L), and Zn (up to 354 µg/L) concentrations. The stable isotopes of O and H of the groundwaters are essentially identical to the surface waters and plot close to the local and global meteoric water lines, indicating that the waters represent modern recharge, consistent with the generally low salinities of all the waters (total dissolved solids range from 98 to 1320 mg/L). Sulfur and Sr isotopes are consistent with proximal waters interacting with the Casino rocks and mineralization; a sulfide-rich bedrock sample from the deposit has delta-34S = -1.2 permille and proximal groundwaters are only slightly heavier (-0.3 to 3.1 permille). These geochemical and isotopic results indicate that surface water geochemistry is a suitable medium for mineral exploration for porphyry-style mineralization in the Yukon, and similar unglaciated regions in Canada. The atypical geochemical signature (Mo, Se, Re, As, Cu) of these types of deposits are typically reflected in the water chemistry and S isotopes provide a more local vectoring tool.

Full text
Abstract:
Cruise AL534/2 is part of a multi-disciplinary research initiative as part of the JPI Oceans project HOTMIC and sought to investigate the origin, transport and fate of plastic debris from estuaries to the oceanic garbage patches. The main focus of the cruise was on the horizontal transfer of plastic debris from major European rivers into shelf regions and on the processes that mediate this transport. Stations were originally chosen to target the outflows of major European rivers along the western Europe coast between Malaga (Spain) and Kiel (Germany), although some modifications were made in response to inclement weather. In total, 16 stations were sampled along the cruise track. The sampling scheme was similar for most stations, and included: 1) a CTD cast to collect water column salinity and temperature profiles, and discrete samples between surface and seafloor, 2) sediment sampling with Van Veen grab and mini-multi corer (mini-MUC), 3) suspended particle and plankton sampling using a towed Bongo net and vertical WP3 net, and 4) surface neusten sampling using a catamaran trawl. At a subset of stations with deep water, suspended particles were collected using in situ pumps deployed on a cable. During transit between stations, surface water samples were collected from the ship’s underway seawater supply, and during calm weather, floating litter was counted by visual survey teams. The samples and data collected on cruise AL534/2 will be used to determine the: (1) abundance of plastic debris in surface waters, as well as the composition of polymer types, originating in major European estuaries and transported through coastal waters, (2) abundance and composition of microplastics (MP) in the water column at different depths from the sea surface to the seafloor including the sediment, (3) abundance and composition of plastic debris in pelagic and benthic organisms (invertebrates), (4) abundance and identity of biofoulers (bacteria, protozoans and metazoans) on the surface of plastic debris from different water depths, (5) identification of chemical compounds (“additives”) in the plastic debris and in water samples.
