Colonization of microorganisms from the ocean floor into the water column

Planktonic foraminifera are key to understanding and deciphering past climate. They live and lived in the water column, but their origins are unclear. In a ...

Arctic Carbon Conveyor Belt Discovered

Every year, the cross-shelf transport of carbon-rich particles from the Barents and Kara Seas could bind up to 3.6 million metric tons of CO₂ in the Arctic ...

Internal structure of planktonic foraminiferal shell obtained by an X-ray Micro-Computer-Tomography. It shows the preserved shell (left) and dissolved shell (right). The heat map indicates the spatial distribution of density and porosity in the shell. Red

New method reveals carbon distribution of the past in the Southern Ocean

Oceans, and in particular deep water circulation in the Southern Ocean, play and have played an important role in the global carbon cycle. Using carbonate ...

Ocean Heating Will Increase Rainfall in East Asia, Study Suggests

Upper ocean heating in the equatorial Pacific – a key oceanographic region in Earth’s climate system – is likely to make the East Asian monsoon season ...

Planktonic foraminifera are microorganisms that live in the uppermost water layers of all oceans. When they die, their small calcareous shells sink to the bottom of the ocean and remain there in the sediment. Such fossil foraminifera document the state of

The future of marine biodiversity under global warming

Human-induced climate change has already had a major impact on Earth's biodiversity. The habitat of many species – including those in the oceans – Is ...
