El estallido de burbujas acelera el deshielo de los glaciares

by Erin Martin-Jones 28 November 202328 November 2023

Tener en cuenta el efecto burbuja podría mejorar las estimaciones sobre el deshielo de los glaciares submarinos y prever mejor su contracción a medida que se calientan los océanos.

Popping Bubbles Make Glaciers Melt Faster

by Erin Martin-Jones 25 October 202328 November 2023

Accounting for the newfound bubble effect could improve estimates of how sea-terminating glaciers melt underwater—and better anticipate their shrinkage as oceans warm.

Shifts in Tectonic Plates Change Biodiversity

by Danielle Beurteaux 19 September 202319 September 2023

A 36-million-year cycle of marine biodiversity booms and busts matches the movements of plate tectonics, linking what happens deep below the ocean to what’s happening in it.

Clues from a Subglacial Lake for Holocene Grounding Line Change

by Susan Trumbore 2 May 20231 May 2023

Organic carbon sampled in the lake contained radiocarbon, indicating connection to the ocean in the mid-Holocene, when the grounding line was up to 260 kilometers inland of its current position.

The lower part of Bear Glacier, Alaska, tripled in velocity in 2019, a phenomenon largely attributable to an ice-dammed lake suddenly draining through it.
