The large shelf bordering Alaska extends across many physiographic and climatic regions. It is, therefore, not simple to classify the entire shelf into a few identifiable environments. The most commonly used parameters for defining the sedimentary environments are the sediment parameters. Lacking thorough knowledge of the hydrodynamic and other related information, the sedimentary parameters fail to fully elucidate the critical aspects of deposition, and especially the characteristic process over a large area. They may, however, fully characterize the sediments on a regional basis, particularly in a region with one or two identifiable detritus sources and with not too complex transporting agents.
