A Geophysical Investigation of the Arctic Sea Ice Surface
The oldest records of the Arctic sea ice pack illustrate a frozen, yet dynamic icescape composed of hummocks and weathered ridges draped in thick snow. In recent decades, the effects of climate change have transformed this ... -
Acquisition, degradation, and cycling of organic matter within sea-ice brines by bacteria and their viruses
Marine dissolved organic carbon (DOC) is a major component of the global carbon pool, and thus can have significant effects on global carbon cycling. Within the oceans, DOC is largely regulated by microbial communities, ... -
Microbial Evolution In Sea Ice: Communities To Genes
(2009-12-15)Microbial communities encased in growing sea ice must contend with the combined stresses of low temperature and high salinity, environmental pressures that only intensify over the course of the winter. This harsh physical ... -
Sea ice and upper ocean variability in the Southern Ocean
This dissertation explores key physical mechanisms that control upper ocean and sea ice variability in the Southern Ocean. The first portion of this work presents an observational analysis of wintertime upper ocean stability ...
