MonitoringLocationDescriptionText Site 0023 was located near the west mouth of Usof Bay (Unalaska Island), just inside Cape Prominence. While enroute to this site we encountered several large schools of Atka mackerel feeding at the surface off Cape Prominence. They appeared to be feeding on small fish, which may have been feeding on mysids. Dense swarms of mysids were noted near the feeding Atka mackerel. We took videos of the Atka mackerel. Site 23 had a boulder substrate at 50 ft. Small (2 m wide) patches of coarse white sand/shell were scattered between the boulders. Visibility was about 40 ft. Bottom temperature was 9 C. This was a diverse area. The dominant algae were Saccharina latisama, Laminaria bongardiana, Agarum sp. and Neoptilota asplenioides. Dominant macroinvertebrates included at least 4 species of bryozoans, Acmaea mitra, and the unidentified small unstalked ascidian we called ?Little Piggies?. Dominant fishes included dark-colored rockfish and kelp greenling, Hexagrammos decagrammus.
