MonitoringLocationDescriptionText This site was off Peacock Point on NW Unalaska Is. The target site exceeded 115 ft, therefore, we moved from the end of the point toward the mainland and found a sampleable depth at 47 ft between two small islands. The site was adjacent to a dense bed of Alaria. The substrate was boulder/bedrock with a lush canopy of kelps. Bottom temperature was 7 C and visibility approximated 30 ft. Dominant kelps included Laminaria bongardiana, L. longipes, Agarum sp., and Thalassiophyllum sp. Dominant macrofauna included Juvenichiton saccharinus and Musculus vernicosa. Dominant fishes were rock greenling (Hexagrammos lagocephalus), kelp greenling (H. decagrammus), black rockfish (Sebastes melanops), and red Irish lord (Hemilepidotus hemilepidotus). Also, there were dense clouds of mysids near bottom among the kelp.
