This study aimed to investigate the acute and chronic toxic effects of two thermodynamic inhibitors (methanol and ethylene glycol) widely used in deep-sea oil and gas operations on two typical marine ...
Anthropogenic and climatic perturbations threaten to destabilize gas hydrates and release methane from its vast subseafloor reservoir. Yet the deep-sea ecosystem responses remain poorly understood. Ou...
Giant Antarctic iceberg calving is projected to increase with climate change, affecting ocean circulation, nutrient supply, and carbon cycling. These icebergs can stimulate primary production and infl...
Emerging organic contaminants (EOCs), including per- and polyfluoroalkyl substances (PFASs), polybrominated diphenyl ethers (PBDEs), polycyclic aromatic hydrocarbons (PAHs), and antibiotics, persist i...
At the subantarctic islands of South Georgia, albatrosses and petrels occupy a range of trophic niches, from zooplanktivore to top predator. Interspecific variation in mercury (Hg) contamination is th...
Microplastics (MPs) have emerged as pervasive contaminants in marine ecosystems, posing escalating ecotoxicological risks across trophic levels. This review highlights the current knowledge on the sou...
The 2016 El Niño was the strongest warm-phase of the El Niño-Southern Oscillation recorded to date over the 21st century, leading to the development of severe ocean surface temperature anomalies - mar...
There is a common misconception among ocean scientists and policy makers that mesopelagic (200-1000 m) food webs are an unexploited "final frontier" of living marine resources. It is true that there a...
Stenotrophomonas sp. strain WO2 was isolated from deep-sea sediments at the Haima cold seep (South China Sea) using crude oil as the sole carbon source. The draft genome contains 4,772,190 bp with a G...
The ocean carbon cycle spans multiple scales and reservoirs, challenging efforts to build a coherent picture and fostering misconceptions or fragmented narratives in science and public discourse. Comm...
The Central Arctic Ocean is undergoing rapid environmental change associated with sea-ice retreat. The sea-ice bottom and adjacent under-ice waters are key zones for particulate organic matter (POM) a...
Marine oil spills are globally widespread, posing significant threats to marine wildlife. While the spatial and temporal distribution of oil concentrations in the environment can be modeled with high ...
The anaerobic oxidation of methane and higher C2+ alkanes is a dominant metabolism within hydrocarbon-rich deep-sea sediments and is largely mediated by alkane-oxidizing archaea in metabolic partnersh...
The subseafloor biosphere is one of the largest ecosystems on Earth, hosting dense populations of microbial cells. Microbial activity is critical to the Earth's geochemical cycles of major elements su...
Deep-sea hydrothermal sediments represent critical zones for archaea-driven biogeochemical cycling, yet the ecological differentiation of archaeal communities across hydrothermal gradients remains poo...
Benthic prokaryotic communities in deep-sea sediments remain poorly studied. They are constrained by organic matter availability and oxygenation in warm deep-sea ecosystems. Here, we investigated bent...
The Gulf Stream is important for the climate system through its transport and air-sea exchange of heat. What is less well accepted is the role of the Gulf Stream in the carbon cycle. Here we examine h...
The Arctic and sub-Arctic are warming at least three times faster than the global average, altering terrestrial carbon delivery to the oceans and marine carbon cycling. The sequestration of such carbo...
The marine dissolved organic matter (DOM) pool is one of Earth's largest carbon reservoirs and a critical regulator of global carbon flux, yet the microbe-molecule interactions governing it remain lar...
Seamount ecosystems are increasingly exposed to rapid oceanographic change, including warming waters, declining oxygen concentrations, and the upward migration of carbonate saturation horizons. Togeth...
