Kristin Laidre is currently a research scientist at the Polar Science Center, Applied Physics Lab, University of Washington. She is partially supported by the Greenland Institute of Natural Resources in Nuuk, Greenland. Her primary research interests lie in spatial modeling of movement and spatially-explicit foraging ecology of top marine predators. She is interested in how environmental features and habitat variables manifest themselves as constraints on movement and behavior, and how these constraints differentially impact demographics of sub-populations or metapopulations of marine species. Her research is focused on exploring these relationships using satellite and archival telemetry, in combination with remotely-sensed satellite data and quantitative spatial models in a Geographic Information System (GIS). Her research also links spatial environmental fluctuation to bioenergetic models and food webs in the marine ecosystem. Much of her research is focused in the high Arctic, where both short food chains and very limited and specific production periods strongly shape the behavior of top predators.

This project aims to understand and quantify the effects of sea ice loss on polar bears in East and West Greenland (Baffin Bay). Longitudinal (cross-time) comparisons of movement behavior and habitat selection will be driven by an analysis of a multi-decadal satellite telemetry dataset on polar bear movements in Baffin Bay and East Greenland, beginning when sea ice concentration and break up date started to decline (1991-1997) and encompassing present day conditions (2007-2013).read more »
The Arctic is currently undergoing rapid and extraordinary large-scale changes related to natural resource development, marine shipping, transportation, infrastructure, and sea ice loss, and as a consequence there will be an imminent and uniform increase in anthropogenic sound. Narwhals are an important representative species for understanding both increasing noise in the Arctic and loss of sea ice, and the joint effects of these impacts on their behavior and ecology.read more »
