Las olas de calor marinas lentifican el flujo de carbono de los océanos

by Mack Baysinger 5 January 20265 January 2026

Cuando el plancton se encuentra en agua caliente, la materia orgánica se estanca en la superficie e interrumpe el transporte de carbono hacia el fondo océanico.

Ocean Tunneling May Have Set Off an Ancient Pacific Cooldown

by Larissa G. Capella 18 November 202518 November 2025

The ocean’s depths cooled off about 1.5 million years ago, and scientists think watery tunnels from the south may be to blame.

Decadal Forecasts with a SMYLE

by Kristopher B. Karnauskas 13 August 202511 August 2025

Scientists use a large suite of simulations with an established climate model to predict the Pacific Decadal Oscillation up to one year in advance, but El Niño can still get in the way.

Iron Emissions Are Shifting a North Pacific Plankton Bloom

by Mark DeGraff 6 August 20256 August 2025

Some of the iron emitted by industrial activity in East Asia is carried by winds into the North Pacific, where it nourishes iron-hungry phytoplankton.

Magnitude-8.8 Earthquake Strikes Western Pacific

by Jennifer Schmidt 30 July 202530 July 2025

One of the strongest earthquakes ever recorded struck off the eastern coast of Russia’s Kamchatka Peninsula Wednesday morning local time. Initially pegged at a magnitude-8.0, the quake was eventually upgraded to a magnitude-8.8. Adjusted magnitude estimates are not unusual for large earthquakes as more data become available.
