Common eiders dive to feed on benthic invertebrates in an arctic polynya at the Belcher Islands, Nunavut. This clip, filmed in March 2009, is a compilation of footage from our first 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.
This sequence is the original 2002 footage of Common Eider Ducks diving under the sea ice in an arctic polynya. This location was 11.3 m deep over extensive mussel beds. This sequence is referenced in several published articles and books and represents a different ecological scenario than the 2009 sequence.
