Subglacial Melting

This month we spotlight research using a regional implementation of MITgcm to explore Antarctic subglacial runoff.

A team of researchers from China and the US has created a new atmospheric ensemble forcing for MITgcm to improve the accuracy and the uncertainty estimation of Antarctic sea ice simulation.

A team, bringing together researchers from China, Europe, and the US, use MITgcm to develop a new data assimilation system for the Southern Ocean with the aim of improving sea-ice thickness estimates in the region.

Geologists from WHOI and UMass have been using MITgcm to probe whether melting arctic sea-ice could have slowed the AMOC enough to precipitate the Younger Dryas.

Researchers use MITgcm to understand how phytoplankton blooms and inorganic carbon respond to sea-ice variability in the West Antarctic Peninsula.

MITgcm underpins a new Chinese Arctic sea-ice prediction system.

This month we turn our attention to scientists working at NASA JPL who have been using MITgcm to examine what sets the thickness of so-called “Winter Water” in a region of the Antarctic off shore from the Pine Island Glacier.

MIT postdoc Roberta Sciascia has been using MITgcm to explore the variations in submarine melt rate of Helheim Glacier induced by glacier and intermediary circulations.

Cool off with a study from Ashkenazy, Gildor, Losch and Tziperman who use MITgcm to explore the ocean in models of snowball earth.

In a novel approach, MITgcmers Ian Fenty and Patrick Heimbach use optimal state and parameter estimation to improve the sea-ice simulations.
