Summary: This study investigates the microbial ecology of oxygen minimum zones (OMZs) in the Andaman Sea and eastern Bay of Bengal. The results show that oxygen is the most important driver of microbial community structures, with microbial diversity being highest in oxygen limited zones (OLZs). Co-occurrence network analysis reveals key taxa that play important roles in the microbial community interactions. Functional prediction indicates that microbial taxa involved in nitrogen and sulfur cycling are more abundant in OMZs.

Summary: Recent reports have shown a small but significant decrease in global marine primary production, mainly attributed to the northern Indian Ocean, particularly the Bay of Bengal. Primary production in the Bay of Bengal is historically driven by diatom and chlorophyte clades, with recent increase in cyanobacterial abundance. Changes in community composition of primary producers have been observed, possibly influenced by decreasing nitrate concentrations. This shift in primary producers may impact oxygen concentrations in the Bay of Bengal's low-oxygen intermediate waters.

Summary: Oxygen limited marine environments play a crucial role in global nutrient cycling and habitat availability. However, finding suitable proxies for paleoclimate interpretations is challenging. This study suggests using Mg/Ca ratios to quantitatively reconstruct paleotemperatures of oxygen minimum zones. Mn/Ca and Zn/Ca ratios can be used to reconstruct the habitat of G. hexagonus. Sr/Ca ratios show a strong correlation with dissolved oxygen, indicating its potential as an indicator of oxygen minimum zone intensity. Analyzing these trace element ratios in the shells of oxygen minimum zone species can greatly enhance multiproxy reconstructions.

Summary: Primary production in the Bay of Bengal is affected by the unavailability of inorganic nutrients and the sinking of organic matter. Organic nutrients support primary production, and internal cycling is important in the bay. Anthropogenic nitrogen does not significantly affect the biogeochemistry of the region. Human activities have turned the Bay of Bengal into a sink for atmospheric CO2.

Summary: Recognizing the prokaryotic community and its functions in hypoxic (>5 to <= 60 mu M O-2) environments before further expansion of OMZs is critical. We demonstrate the prokaryotic community and its potential functions in nitrogen metabolism in the Bay of Bengal (BoB), where oxygen concentration is barely above suboxic level. This study highlighted that Trichodesmium might be an essential carbon and nitrogen source in the maintenance of the BoB OMZ. Additionally, we suggest that the lack of N-2 production in the BoB would change if the BoB OMZ became anoxic, and the expansion of OMZs in the global ocean may potentially increase the use of nitrate by SAR11.

Summary: This study presents the concentrations and stable isotope compositions of Te in ferromanganese crusts collected from the slope of two seamounts in the Northwest Pacific Ocean. The Te concentration decreases sharply with depth at shallow regions, while the Te isotope composition exhibits two trends depending on water depth. These variations may be related to co-precipitation processes with Fe and oxidation involving Mn, as well as changes in dissolved oxygen concentration in seawater. The Te isotope compositions in ferromanganese crusts could potentially be used as a proxy for changes in the oxygen minimum zone of paleoceans.

Summary: Observations suggest that the tropical Pacific Ocean has experienced oxygen loss and expansion of its oxygen minimum zone since the 1960s. The attribution of this phenomenon to anthropogenic forcing is challenging due to limited data availability and natural variability introduced by the Pacific Decadal Oscillation (PDO). Using observations and hindcast simulations from two global ocean circulation models, it is found that the PDO influences oxygen dynamics and OMZ extent in the tropical Pacific. However, the separation of anthropogenic trend from natural variations is hindered by the incomplete coverage of observations.

Summary: Ocean warming and acidification have interactive effects on coccolithophore physiology and result in significant biogeochemical changes. In this study, we investigated the long-term effects of different transitional periods on the physiology of the coccolithophore Chrysotila dentata under present and projected ocean conditions. Our results showed that physiological responses of HTHC cells decreased with long-exposure, but the overall physiology of HTHC cells continued to improve with each generation. This suggests that coccolithophore resilience increases over generations under ocean warming and acidifying conditions.

Summary: Data on the independent or combined effects of ocean acidification and warming on coastal eutrophication and organic pollution are limited. Acidification favors eutrophication and organic pollution, while warming inhibits these two variables. However, the interaction between acidification and warming in the future may exacerbate organic pollution but mitigate eutrophication.

Summary: This study investigated the effects of human activity-induced environmental heterogeneity on the chromophytic phytoplankton in Bohai Bay. The results showed that human disturbance had a greater impact on the phytoplankton communities than natural factors. The assembly of the communities was influenced by both stochastic and deterministic processes, with different importance rankings in nearshore and offshore areas. Dissolved inorganic nitrogen, eutrophication index, and chemical oxygen demand were the main environmental factors affecting the phylogenetic turnover of the phytoplankton.

Summary: This study used the Utermohl method and carbon volume conversion to investigate the composition and distribution of phytoplankton in the western Tropical Pacific Ocean. Four primary groups of phytoplankton were identified: dinoflagellates (181 species), diatoms (73 species), cyanobacteria (4 species), and chrysophyceae (2 species). Clustering analysis revealed that phytoplankton could be classified into four groups based on their composition, which were closely related to ocean currents. The study also found that diatoms were abundant in areas influenced by current-seamount interaction, while areas with little influence from ocean currents were dominated by Trichodesmium. The majority of phytoplankton had an equivalent spherical diameter (ESD) of 2-12 μm, with some exceeding 25 μm. Nanophytoplankton (ESD = 2-20 μm) dominated cell abundance, but microphytoplankton (ESD = 20-200 μm) contributed significantly to carbon biomass (792.295 mg m(-3)). This study provides valuable insights into the distribution and composition of phytoplankton in the western Tropical Pacific Ocean and their relationship with ocean currents, as well as fundamental information regarding cell size and carbon biomass within the region.
