Iceberg Surge During Last Deglaciation May Have Had Two Pulses

by Sarah Stanley 27 April 20174 May 2022

Seafloor sediment cores provide new clues that could help clarify the influence of ice sheet collapse on a period of ocean cooling marked by slowed deepwater circulation.

Icebergs Fertilize Southern Ocean, Sequester Carbon

by JoAnna Wendel 15 January 201617 August 2022

Huge, drifting ice rafts (the white spot on the satellite image below ) shed minerals as they melt, painting trails of nutrients, teeming phytoplankton, and chlorophyll across hundreds of kilometers of ocean.
