Reconstruction of Antarctic sea ice thickness from sparse satellite laser altimetry data using a partial convolutional neural network [PDF]

open access: yesarXiv
The persistent lack of spatially complete Antarctic sea ice thickness (SIT) data at sub-monthly resolution has fundamentally constrained the quantitative understanding of large-scale sea ice mass balance processes. In this study, a pan-Antarctic SIT dataset at 5-day and 12.5 km resolution was developed based on sparse Ice, Cloud and Land Elevation ...

A Fast Particle-Based Approach for Calibrating a 3-D Model of the Antarctic Ice Sheet [PDF]

open access: yesarXiv, 2019
We consider the scientifically challenging and policy-relevant task of understanding the past and projecting the future dynamics of the Antarctic ice sheet. The Antarctic ice sheet has shown a highly nonlinear threshold response to past climate forcings.

Improved Simulation of Antarctic Sea Ice by Parameterized Thickness of New Ice in a Coupled Climate Model

open access: yesGeophysical Research Letters
Sea ice formation over open water exerts critical control on polar atmosphere‐ocean‐ice interactions, but is only crudely represented in sea ice models. In this study, a collection depth parameterization of new ice for flux polynya models is modified by ...

Multimodel Analysis of the Atmospheric Response to Antarctic Sea Ice Loss at Quadrupled CO2

open access: yesGeophysical Research Letters, 2019
Antarctic sea ice cover is projected to significantly decrease by the end of the twenty‐first century if greenhouse gas concentrations continue to rise, with potential consequences for Southern Hemisphere weather and climate.

Influence of sea surface temperature in the tropics on the Antarctic sea ice under global warming

open access: yesЛëд и снег, 2019
Sea ice fields in the Antarctic, in contrast to the Arctic ones, did not show a reduction in observed global warming, whereas the global climate models indicate its certain decrease.

Improving Our Understanding of Antarctic Sea Ice with NASA's Operation IceBridge and the Upcoming ICESat-2 Mission [PDF]

open access: yes
Antarctic sea ice is a crucial component of the global climate system. Rapid sea ice production regimes around Antarctica feed the lower branch of the Southern Ocean overturning circulation through intense brine rejection and the formation of Antarctic ...

Chlorophyll a in Antarctic sea ice from historical ice core data [PDF]

open access: yes, 2012
Sea ice core chlorophyll a data are used to describe the seasonal, regional and vertical distribution of algal biomass in Southern Ocean pack ice. The Antarctic Sea Ice Processes and Climate - Biology (ASPeCt - Bio) circumpolar dataset consists of 1300 ...
