Sediment quality in depositional areas of Shelikof Strait and outermost Cook Inlet. Sediment profile imaging report
Technical Report
·
OSTI ID:350675
A Sediment Profile Imaging (SPI) survey was conducted in July, 1997 in Shelikof Strait and Lower Cool Inlet as part of a larger study of sediment quality in relation to offshore oil development. The purpose of the SPI survey was to delineate sediment type, provide information on patterns of sediment deposition and erosion, and describe biological community characteristics in the region. A total of 57 stations were sampled during a nine-day cruise. Based on the reflectance contrast of the sediment profile, there were no areas suffering from excess carbon loading and no areas had indications of excess chemical contamination. All the data from the profile images point to both high sediment quality and benthic habitat values at depositional sites. In particular, the images from deep water (depositional) stations in Shelikof Strait indicate a largely undisturbed, low-energy depositional basin.
