Meteorological forcing of sea ice concentrations in the southern Beaufort Sea over the period 1979 to 2000

Abstract: [1] Northern Hemisphere sea ice areal extent, and perhaps thickness, have shown a detectable reduction over the past several decades. This situation is particularly apparent in the southern Beaufort Sea. The region encompassing the Mackenzie Shelf, the Cape Bathurst Polynya, and the Canada Basin mobile pack ice all occur in a region referred to here as the Canadian Arctic Shelf Exchange study area (CASES). In this paper we present results from an analysis of atmosphere, sea ice, and ocean coupling over the per… Show more

“…South of Banks Island, we encountered open water and a dramatic temperature increase from below 0 to 6 • C, which coincided with a salinity increase from 27 to 32. This was probably associated with wind-induced upwelling of warm, salty subsurface water around the Cape Bathurst Peninsula, where the shelf break in the Amundsen Gulf creates a polynya in spring, which recurs annually (Barber and Hanesiak, 2004). At this same location Fransson et al (2009) found elevated fugacity of CO 2 (f CO 2 ) in the surface water, which indicates upwelling of CO 2 -rich subsurface water.…”

“…The area is characterized by 3 main features related to sea-ice dynamics: on the shelf, the new sea ice typically forms in October; offshore, the permanent pack ice comprises annual and multiyear sea ice and drifts following the Beaufort gyre; the Cape Bathurst polynya is generally located at the entrance of the Amundsen Gulf (Barber & Hanesiak 2004).…”

“…1) is a relatively narrow Arctic shelf (width ∼120 km, length ∼530 km) covered with ice from October until May to early August, reaching a maximum thickness of 2-3 m in March-April (Barber and Hanesiak, 2004). The Mackenzie River supplies ∼330 km 3 yr −1 of freshwater and 124 × 10 6 t yr −1 of sediment on the shelf (Gordeev, 2006).…”
