This clip, filmed in March 2009, is a compilation of footage from our new HD underwater monitoring system .
It portrays a different oceanographic and ecological situation than the
original underwater footage from 2002,
which is referenced in several publications. Please view the uneditied 2002 footage if you are viewing this in
reference to that literature. Notable differences include depth profile, dive angle, passive/active ascent,
prey abundance and composition, and oceanographic context.
The scenario depicted here and its importance to winter population structure of eiders will be formally
described in forthcoming research.
