Mesopelagic fishes transport a vast biomass of organic material between surface and deep waters through diel vertical migration (DVM), which plays a crucial role in both food web functioning and deep-...
In the context of global biodiversity decline, the monitoring and assessment of marine biodiversity have gained increasing importance. Thaliacea, a group of filter-feeding gelatinous zooplankton, play...
Direct observations from submersible dives off the Galapagos Islands have revealed that Pelagothuria natatrix, the only known holopelagic echinoderm, actively intercepts settling particles well before...
Carbon in the asthenosphere is unevenly distributed, reflecting interactions between the depleted mantle and materials added by plumes or subducting slabs. Nevertheless, mid-ocean ridge basalts (MORB)...
In this paper, we present results that have important implications for understanding the sedimentation process and for evaluating the carbon cycle in deep-sea sediment of the southern Gulf of Mexico (...
Mangrove ecosystems are highly efficient natural carbon sinks, yet quantifying soil organic carbon density (SOCD) across stand ages is critical for evaluating restoration benefits. This study integrat...
During the Paleocene-Eocene Thermal Maximum (PETM), there was an increase in global temperatures and emissions of isotopically depleted carbon, resulting in a negative carbon isotope excursion (CIE). ...
Bacterial adaptation to fluctuations in salinity includes the intracellular accumulation of organic compounds called compatible solutes (CS) such as the amino acid derivatives ectoine and 5-hydroxyect...
Coral reef islands face escalating degradation due to extreme substrate infertility (coral sand) and waste management challenges in isolated marine environments. High-oil food waste composting offers ...
Mangrove ecosystems are our most carbon-rich forests. They play a vital role in regulating carbon fluxes to the ocean (outwelling). These ecosystems are increasingly threatened by degradation. Here we...
Increasing global demand for nickel, an essential metal in low-carbon technologies and stainless steel, is driving a surge in mining in strongholds of tropical biodiversity. We use a global mine-by-mi...
Seaweeds are valuable marine resources rich in polysaccharides and polyphenols. Carbon dots (CDs) from Gracilaria salicornia (GS-CDs), Halymenia dilatata (HD-CDs), Sargasum polycystum (SP-CDs), Spatog...
The equilibrium between hydrated and hydrolysed forms of CO2 in water is central to a multitude of processes in geology, oceanography and biology. Chemistry of the carbonate system is well understood ...
Ocean dumping of sewage sludge at the East Sea "Byeong" (ES-B) deep-sea disposal site was prohibited in 2016 under strengthened national and international regulations. This study presents the first lo...
Seagrass meadows of Thalassia testudinum are key components of blue carbon ecosystems and effective bioindicators of environmental contamination due to their ability to incorporate both inorganic and ...
Carbon fixation in marine ecosystems is a vital process that contributes to climate regulation, with ocean sediments playing a critical role in carbon sequestration. This process is driven by chemolit...
Emerging organic contaminants (EOCs), including per- and polyfluoroalkyl substances (PFASs), polybrominated diphenyl ethers (PBDEs), polycyclic aromatic hydrocarbons (PAHs), and antibiotics, persist i...
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...
Climate change threatens polar ecosystems through rising temperatures and changing light regimes. Phytoplankton release of dissolved organic carbon (DOC) is a major carbon-cycle component, yet it rema...
