An overview is presented of the instrumentation, ice conditions and available load information on the SSDC at four of its Beaufort Sea deployments. This paper concentrates on the Phoenix and Aurora sites, both of which were surrounded by an extensive rubble field, since those were the only sites for which load data are available. Global loads at those sites were estimated from in situ load panels. Thirteen wind-driven or thermally activated events occurred at the Phoenix and Aurora sites, resulting in global loads up to 80 MN. The corresponding Line Loads and Global Pressures were up to 1.8 MN/m and 1.2 MN/m2, respectively. Estimates of Line Load and Global Pressure showed that the presence of grounded rubble reduced the transmitted loads, whereas floating rubble did not. NRC publication: Yes
