The ocean carbon sink – impacts, vulnerabilities and challenges [PDF]
Carbon dioxide (CO2) is, next to water vapour, considered to be the most important natural greenhouse gas on Earth. Rapidly rising atmospheric CO2 concentrations caused by human actions such as fossil fuel burning, land-use change or cement production ...

This review elucidates the molecular mechanisms of algicidal bacteria, highlighting critical behaviours like chemotaxis, quorum sensing and extracellular vesicle release. It details how these actions disrupt algal cellular integrity, photosynthesis and calcium homeostasis, providing a theoretical foundation for controlling harmful algal blooms ...

Loss of fixed nitrogen causes net oxygen gain in a warmer future ocean
Ocean anoxic events threaten marine ecosystems, and they are predicted to increase as the climate warms. Using model simulations, Oschlies and colleagues show that in spite of rising temperatures, after transitory deoxygenation, microbial denitrification

Changes in benthic ecosystems and ocean circulation in the Southeast Atlantic across Eocene Thermal Maximum 2 [PDF]
Eocene Thermal Maximum 2 (ETM2) occurred -1.8 Myr after the Paleocene-Eocene Thermal Maximum (PETM) and, like the PETM, was characterized by a negative carbon isotope excursion and warming.

Unravelling Marine Benthic Functioning Shifts Under Ocean Acidification
Ocean acidification is reshaping temperate shallow marine benthic communities and the way they function. Using community transplants at natural CO2 vents, we show that biodiversity loss under declining pH reduces biomass and calcification, while enhancing photosynthesis and nutrient uptake.

Across 12 long‐term monitoring sites on three Northeast Pacific seamounts, 163 of 844 cold‐water coral and sponge individuals were lost between surveys 3–5 years apart, with abundance declining at five sites and condition (i.e., health) declining at nine.

Ocean acidification, deoxygenation, and warming are three interconnected global change challenges caused by increased anthropogenic carbon emissions. These issues present substantial threats to marine organisms, ecosystems, and the survival of coastal ...

The source‐to‐sea nexus between water and ocean law: An international and EU perspective
Abstract The source‐to‐sea (S2S) approach provides a systemic framework for analysing the governance of naturally interconnected freshwater and marine ecosystems. This paper examines the extent to which the S2S approach is reflected in key international and EU water and ocean law instruments, as well as the legal and governance implications of said ...

Due to global warming and the excessive input of nutrients resulting from human activities, ocean deoxygenation is gradually intensifying. However, the sparse spatiotemporal distribution of in situ global dissolved oxygen (DO) observations poses a ...
