Characterization of the Circulation on the Continental Shelf Areas of the Northeast Chukchi and Western Beaufort Seas (AK-12-03a)

This study provided an improved understanding of the physical oceanography of the northeastern Chukchi shelf and exchanges between the Chukchi/Beaufort shelves and the adjacent continental slope. It expanded upon data collections from moorings, gliders, and three high frequency radars (HFRs) that were part of a previous study that ended in 2011, and integrated a wide variety of observations obtained through several partnerships from moored oceanographic instruments, satellite-tracked drifters, hydrography (both recent, from towed-CTD and autonomous underwater vehicles, and historic, from ship measurements), highfrequency radars (HFR), meteorological buoys, and satellite imagery. These observations led to characterization of flow in the study area that were used to map circulation of surface and subsurface flow for the northeastern Chukchi and western Beaufort Seas. These results are documented in the final report, and included the discovery of several important differences from predictions based numerical circulation model output. Several peer reviewed publications in prominent physical oceanography journals and datasets used and collected in this study are cited therein.
