Previous research suggested that the intrusion of low-nutrient Gulf Stream water into the Mid-Atlantic Bight would reduce productivity, but a new study finds that it can also lead to chlorophyll hot spots.
The unicellular plants more readily take up iron in the presence of salp feces than in krill feces, an experiment in Antarctica reveals.
New insights into the dynamics of ocean features known as deep chlorophyll maxima set the stage for better understanding of their role in carbon cycling.
Tiny microorganisms in the Southern Ocean affect the way the rest of the world’s seas respond to carbon dioxide.
New research finds that nanoplankton may have a larger influence on carbon cycling than previously thought.
New research reveals that tiny single-celled organisms in the Arctic Ocean are growing more numerous as climate change thins the ice.
Acoustic tools identify the population of “the most important fishery in the Southern Ocean.”
Using an unsupervised learning algorithm, scientists can create new maps of ecosystem provinces in the ocean, opening the possibility of sharper data collection and monitoring.
Planktonic foraminifera and sea snail numbers swell from April to June in the Barents Sea, but contrary to predictions, the organisms do not appear to be affected directly by high methane levels.
Tiny, shelled protists known as Rhizaria may be responsible for up to one fifth of the total amount of silica produced by the world’s oceanic organisms.
