Science Seen

Research adds to knowledge about polar sea ice

The American Geophysical Union announced the publication of a paper that is helping climate change researchers better understand how to model and understand the role of polar sea ice.

According to the AGU: “Polar sea ice is an indicator and regulator of climate change; its thinning and retreat show the effects of climate warming, and its presence greatly reduces solar heating of the polar oceans. Sea ice also is a primary habitat for microbial communities, sustaining marine food webs. The permeability of sea ice and its ability to transport brine are important to many problems in geophysics and biology, yet remain poorly understood. “

Research published in the latest issue of Geophysical Research Letters, “Thermal evolution of permeability and microstructure in sea ice,” seeks to “generate a unified picture of sea ice permeability through analytical and numerical modeling, as well as through comparisons with field and laboratory measurements.”
