Mapping the Ocean’s Motion Energy

by Veronika Meduna 5 March 20245 March 2024

The ocean is a central component of Earth’s climate system. But it is in perpetual motion, and understanding the transfer of kinetic energy is key to better ocean models.

Nutrients at Depth Can Be Uplifted by the Kuroshio Large Meander

by Takeyoshi Nagai 8 December 20238 December 2023

Aperiodic, southward deflection of the Kuroshio, a.k.a. the Kuroshio large meander, uplifts the nutrients in deep layers to induce offshore phytoplankton bloom.

ENSO Variations Modulate the Kuroshio in the East China Sea 

by Takeyoshi Nagai 7 December 20236 December 2023

Recent warm El Niño Southern Oscillation events strengthened winds over the western Subtropical North Pacific, leading to planetary waves with cyclonic eddies, weakening the Kuroshio in the East China Sea.
