Non-Cognitive Predictors of Student Success:

A Predictive Validity Comparison Between Domestic and International Students

Antarctic sea ice projections are

sensitive to ocean model resolution.

BACKGROUND: Sea ice extent around the Antarctic continent has not declined since 1979. This is in stark contrast to existing climate models that tend to show a strong negative sea ice trend for the same period.

The IPCC SROCC concluded that confidence in Antarctic sea ice projections is low.

METHODS

1. Studying sea ice trends in observations

(1979-2019), CMIP5, and in a HighResMIP projection with the AWI-CM climate model 2. AWI-CM-HR features an ocean with eddy-

permitting and locally eddy-resolving

resolution (up to 8km in Southern Ocean) 3. Compare HR simulation to a more

standard-resolution LR configuration (“CMIP5-type”, with eddy param.)

DOES THE RESOLUTION PLAY A ROLE? YES!

In this quantitative study of hydrous calcium carbonate as ikaite, sea ice cores and brine samples were collected from pack and land fast sea ice between September and December

Piot and von Glasow [2008] showed that the precipitation of calcium carbonate (CaCO 3 ) in sea ice brine is a key process allowing for the rapid acidi fi cation of aerosols
