Linette Boisvert Linette Boisvert

Linette Boisvert uses data from NASA's satellite Aqua to estimate moisture fluxes over the Arctic sea ice. She looks at how these fluxes have changed with the rapidly evolving ice pack and how they are affecting low-level clouds in the Arctic.

Ludovic Brucker Ludovic Brucker

Ludovic Brucker’s research focuses on the investigation of the Earth's polar climate evolution by interpreting air- and space-borne microwave measurements of snow-covered sea ice and ice sheets.

Kimberly Casey Kimberly Casey

Kimberly Casey specializes in glacier dust and debris quantification. During her Ph.D. research, she studied six glacier sites around the world; from volcanically influenced glaciers in Iceland and New Zealand to dust-influenced glaciers in Nepal and Switzerland to bare-ice and soot-influenced glaciers in Svalbard and southern Norway. Her results demonstrate that satellite data can be used to map the geochemical composition of glacier dust and debris.

Lora Koenig Lora Koenig

Lora Koenig is interested in detecting accumulation rate changes over ice sheets using passive microwave satellite sensors, which stand out for their long temporal record of over three decades. She studies the Greenland and Antarctica ice sheets on very small scales, using field techniques like snow pits and ice cores, and over broad scales, using airborne and space-borne sensors. Her ground-based studies have included spending over 12 months in the Arctic and Antarctic to validate satellite measurements and expand algorithms over large areas where ground data are lacking due to harsh conditions.
