MonitoringLocationDescriptionText This site is on the northeast side of Attu Island in Chichagof Harbor. This was a shallow site of only 24 ft on a substrate of fine gravel with occasional boulders. Few flora and fauna were present presumably due to frequent high energy waves. There was an occasional Laminaria bongardiana and thin encrusting coralline alga on the boulders. Often the holdfast was covered by sand. The macrofauna, although few, was dominated by the chitons Tonicella submarmorea and Boreochiton beringensis, and the green sea urchin Strongylocentrotus sp. and rock sole. Bottom temperature was 6 C and visibility was about 5 m. One yellow Irish lord (Hemilepidotus jordani) was taken.
