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.

Glacier Runoff Becomes Less Nutritious as Glaciers Retreat

Javier Barbuzano, Science Writer by Javier Barbuzano 25 November 202525 November 2025

Sediment from retreating, land-terminating glaciers contains proportionally fewer micronutrients such as iron and manganese, reducing the glaciers’ value to microorganisms at the base of the food web.

Against a gray background, strands of multicellular green organisms glow in artificial light.

Marine Heat Waves Slow the Ocean’s Carbon Flow

by Mack Baysinger 3 November 20255 January 2026

When plankton find themselves in hot water, organic matters stalls at the surface and disrupts transport of carbon to the deep ocean.

A group of more than a dozen penguins stand on a rocky shoreline. A glacier or snowy mountain is across the water not too far from them.

Toxic Metal on the Rise in the Baltic Sea

by Amy Mayer 17 June 202417 June 2024

Postwar reconstruction is likely the cause of elevated thallium levels, but low-oxygen, high-sulfide conditions keep the material, which is extremely dangerous to mammalian health, from moving into the human food chain.

A large, goose-shaped lake stretches across Canada’s Northwest Territories. Two red circles and two yellow triangles mark sites where samples were taken from the lake, and the Slave River and the Hay River are both labeled.

Arctic Ice Loss Could Shorten Winter Feeding Time for Zooplankton

by Veronika Meduna 2 October 20232 October 2023

The Arctic’s thinning sea ice allows more light to penetrate deeper into the ocean, holding zooplankton far beneath the surface.
