Sea Ice Properties

Studying the physical properties of sea ice (e.g. temperature, salinity, density, texture) is an important aspect of our work. These properties are the basis of most other studies, describing the complex medium of frozen fresh water and liquid brine (highly saline water). The physical properties are also varying with time through formation and melt processes as well as the interaction with the atmosphere and the ocean.

We perform field observations and numerical simulations in different regions of the Arctic and Antarctic, covering scales from centimeters to hundreds of kilometers. Our data sets span over all seasons, describing a large amount of the annual variability of sea ice. Based on these observations and results, we aim to describe better the evolution of sea ice depending on various environmental conditions in both Polar Regions. 

Our main focuses are studies of sea-ice thickness and snow on sea ice. Both are hot topics in today’s discussion on observed changes in the ice-covered polar oceans.
