Why Did the Deep-Sea Ecosystem in the Eastern Mediterranean Collapse 10,000 Years Ago?
During a dramatic climate change around 10,000 years ago, most bottom-dwelling organisms in the eastern Mediterranean Sea died. Using climate…
Climate Models With High Resolution in the Ocean Can Better Represent European Heat Waves
The North Atlantic significantly influences the weather in Europe. For instance, a cold spell in the subpolar North Atlantic can lead to a heat wave…
How Ocean Eddies Influence the Intensity of Tropical Cyclones
Depending on whether they carry warm or cold water, ocean eddies can intensify or weaken tropical cyclones. A study conducted at the Max Planck…
How to Make Model Experiments on the Atlantic Overturning Circulation More Realistic
Melting ice in the Arctic is causing an increasing amount of freshwater to enter the North Atlantic, which is expected to result in a weakening of…
CELLO: Climate Exploration in Lively Liaison with the Ocean
From September 16 to 18, 2025, around 220 ocean researchers have met at the CELLO conference organized by the Max Planck Institute for Meteorology.…
Weaker Ocean Circulation Could Cost Trillions
A major motor for the global climate is beginning to falter: a massive system of ocean currents called the Atlantic Meridional Overturning…
How the Atlantic overturning got its observing system
The RAPID observing system has monitored the Atlantic Meridional Overturning Circulation (AMOC) at 26.5°N since 2004. Many physical oceanographers…
How katabatic storms in southeast Greenland form dense water in the Irminger Sea
In a new study in the Journal of Geophysical Research: Oceans, Dr. Oliver Gutjahr (Universität Hamburg, Max Planck Institute for Meteorology (MPI-M))…
Project EERIE: Ocean eddies for better climate projections
The Max Planck Institute for Meteorology (MPI-M) is successfully involved in the new EU project EERIE (European Eddy-RIch Earth system models).…

Abrupt CO2 quadrupling: Resolving ocean eddies leads to smaller increase in global mean surface temperature
In a recent study in Geophysical Research Letters, Dr. Dian Putrasahan and colleagues from the department “The Ocean in the Earth System” at the Max…
Ocean modelling at MPI-M – from LSG to ICON-O
The Max Planck Institute for Meteorology (MPI-M) has a long tradition of creating general circulation models of the ocean in order to pursue its…
Shifting winds weakened the recent Southern Ocean CO2 absorption
In a new study, Lydia Keppler and Dr Peter Landschützer from department “The Ocean in the Earth System” at the Max Planck Institute for Meteorology…
