Bio-Argo Floats Reveal Phytoplankton Increase at Ocean Fronts

by Takeyoshi Nagai 20 March 202320 March 2023

Bio-Argo floats and satellite altimeter data reveal that upwelling caused by confluent flow on the warm side of ocean fronts increases phytoplankton carbon and chlorophyll.

Gulf Stream Closes the Valve of the Labrador Current

by Takeyoshi Nagai 17 March 202316 March 2023

Virtual particles released in the Labrador Current revealed that the westward penetration of the current into the shelf seas is inhibited by warm core rings emanating from the Gulf Stream.

Better Resolution Might Unlock the Mystery of Storms

by Bjorn Stevens 13 March 202324 March 2023

Climate models have many persistent and systematic biases, but a new study shows that allowing for a physical rather than statistical representation of energy transport reduces one of them.

Artificial Lake-Level Lowering Alleviates Floods in the Himalayas

by Dongfeng Li 8 March 20236 March 2023

A new model combining future permafrost degradation and related avalanches demonstrates that artificial lake-lowering could significantly reduce the risk of glacial lake outburst floods.
