At-Sea Location of Juvenile and First-Year King Eiders, dated Aporil 3, 2008


June 2008 - December 2011


The goal of this study is to test the hypothesis that population level effects or changes in fish condition can be described relative to thermal habitat and coastal currents, derived from optical and thermal infrared remote sensing data from the nearshore area of the Beaufort Sea. Several objectives make up this larger goal and need to be accomplished to fulfill the intent of this study: 1) biological sampling of fish; 2) collection of thermal data through remote sensing; and 3) the analysis and synthesis of the biological data with remote sensing data
