Scientific sampling of zooplankton in the Atlantic sector of the Southern Ocean has been undertaken since the 1920s, but few analyzed datasets are available to the research community. We provide a database of standardized data derived from samples collected by Bongo nets in this sector between 1996 and 2013, amounting to almost 94,000 individual records. The study region contains some of the highest levels of pelagic biomass in the Southern Ocean and is also undergoing rapid ocean warming and changing seasonality in sea-ice distribution. Data from a single expedition to the sub-Arctic where the same sampling methodology was used are also included. Atlantic water is an increasing influence in that region, as is the prevalence of boreal plankton taxa within Arctic plankton communities. These data will be of value in supporting studies assessing the impacts of climate change on the structure and function of polar pelagic systems.

Sri Lanka is uniquely situated at the junction of the Bay of Bengal (BOB) and the Arabian Sea (AS), where phytoplankton community may be strongly influenced by ocean dynamical processes, particularly mesoscale eddies and the East Indian Coastal Current (EICC). Here, to explore these regulatory mechanisms, phytoplankton and physicochemical parameters were collected from the top 200 m water column in the eastern and southern seas of Sri Lanka during the winter monsoon. Results showed higher concentrations of nutrients and phytoplankton abundance within the regions affected by EICC and cyclonic eddy (CE) compared to anticyclonic eddy (ACE).

Estuarine plumes (EPs) are recognized as critical drivers of dissolved organic matter (DOM) heterogeneity in coastal zones, primarily by inducing phytoplankton blooms and subsequent bottom-water dissolved oxygen (DO) depletion. However, the specific mechanisms governing the EP-driven transformations of DOM molecular composition and biogeochemical fate remain elusive. Here, we integrated optical spectroscopy and Fourier transform ion cyclotron resonance mass spectrometry to characterize the molecular signatures of DOM and their biogeochemical transformations within EP-influenced bottom waters of the Pearl River Estuary.

Hypothesis: Gas hydrate formation in sediments is influenced by the availability of gas-water interfacial areas, which governs gas-water interactions. The surface wettability of sediment particles is expected to affect the spatial distribution of water within the pore space, thereby altering the extent of gas-liquid contact. Consequently, by tuning the wettability heterogeneity of the sediment, the spatial distribution of pore water can be regulated, which in turn influences the gas-water interactions and the kinetics of gas hydrate formation.

Marine litter typically originates from human discards at sea or enters the ocean through land-based pathways such as surface runoff and natural disasters. The extensive accumulation of plastic litter poses severe threats to marine life. In August 2024, a specialized survey was conducted to investigate the distribution characteristics of marine litter and macrobenthic communities across four intertidal zones on Lvhua Island (XIAO'AO, DA'AO, FANGANG, and SHIZIKENG).

Antarctic krill () is the central prey species in the Southern Ocean food web, supporting the largest and fastest-growing fishery in the region, managed by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR). Climate change is threatening krill populations and their predators, while current catch limits do not take into account climate variability or krill population dynamics. In 2024, CCAMLR was unable to renew its spatial catch limits, highlighting the urgent need for improved management of the krill fishery to prevent any harm to the Southern Ocean ecosystem.
