MULTIBEAM BATHYMETRIC SURVEY IS UNDERWAY!
4 June 2009 Pribilof Canyon
Based on previous surveys in this region, it appears as if
typical seafloor type in the upper canyon is compacted sediment with some sand or silt over the top. In this canyon seafloor image, Plumarella seafan corals are densely distributed (right), with a few sponges among coral colonies.
Clean, current-swept gravel bottom is also common at two sub dive sites in the upper portion of Pribilof Canyon (left). In this image, largemouth sculpin, seastars, brachiopods, brittle stars, small demosponges and possibly a conical scleractinian coral are among the invertebrates occupying one dive site in the upper canyon (depth approx 280 m).
