Permafrost was recently listed as a terrestrial Essential Climate Variable and several potential mechanisms of change can be quantified with remote sensing time series. We plan to focus on three aspects: 1) erosion of permafrost dominated coastlines, 2) expansion of thermokarst lakes, and 3) sur... |
EPSCoR - Alaska Adapting to Changing Environments (EPSCoR-ACE)
Dissolved organic carbon (DOC) plays a fundamental role in the biogeochemistry of glacier ecosystems. However, the specific sources of glacier DOC remain unresolved. To assess the origin and nature of glacier DOC, we collected snow from 10 locations along a transect across the Juneau Icefield, Al... |
EPSCoR - Alaska Adapting to Changing Environments (EPSCoR-ACE)
Polar ice sheets and mountain glaciers, which cover roughly 11% of the Earth's land surface, store organic carbon from local and distant sources and then release it to downstream environments. Climate-driven changes to glacier runoff are expected to be larger than climate impacts on other compone... |
