Microorganisms are the engines that drive most marine processes. Ocean modelling must evolve to take their biological complexity into account. Marine microorganisms are crucial for ocean health.

Heterotrophic marine bacteria that live in surface waters use a range of strategies to obtain energy from sunlight, either directly or indirectly, even though they rely on organic compounds for most ...

Marine snow—a mixture of dead plankton, waste, mucus, and other organic material slowly sinking from the ocean’s surface—is an important, but poorly understood, part of the ocean carbon cycle. Credit: ...

The IAEA has redesignated today the Spanish National Accelerator Centre (CNA) in Seville as an IAEA Collaborating Centre for a third term to enhance global marine research using accelerator-based ...

Limited understanding of basic ocean processes is hindering progress in marine carbon dioxide removal, with the on-going commercialization of some approaches 'premature and misguided'. Scientists now ...

The IAEA's Marine Radioactivity Information System (MARIS) allows free access to users to search and download the results of measurements of radioactivity in seawater, biota, sediment and suspended ...

Limited understanding of basic ocean processes is hindering progress in marine carbon dioxide removal, with the on-going commercialisation of some approaches “premature and misguided”. In a new paper, ...

Sweeping changes in marine nutrients may seem to be a likely consequence of increasing global temperatures; however, new research suggests that processes below the ocean surface could play a larger ...
