Abstract
During the period from September 14 through October 10, 1977 the second U.S. Geological Survey geo-environmental cruise was conducted in lower Cook Inlet and on the Kodiak shelf and adjacent upper continental slope, Gulf of Alaska, aboard the R/V SEA SOUNDER (Figure 1, Tables 1, 2 and 3). The objective of this cruise was to study in detail specific potentially hazardous environmental conditions identified as a result of the first reconnaissance geo-environmental cruise conducted from June 18 through July 30, 1976 (Bouma and Hampton, 1976; Hampton and Bouma, 1976). In particular, the distribution and movement of seafloor bedforms were studied in lower Cook Inlet, and sediment dispersal patterns and submarine sediment slides were investigated on the Kodiak shelf and slope. High resolution seismic profiling (sparker, uniboom, minisparker, 3.5 khz, 12 khz) and side-scanning sonar surveys formed the basis for selecting stations for observations with bottom television and 70 mm bottom camera as well as for different types of sampling of surficial sediments (piston corer, gravity corer, hydroplastic corer, Soutar grab sampler). The success of the 1977 cruise was limited by adverse weather conditions.
