JPM Myers 1976 Journal Chukchi Shoreline, Barrow, Alaska 1 August Large densities of a free-swimming amphipod (Ampheliscidae ?? says Carlton), many large majidae ctenophora - up to 6" long, large medusae, [illegible] crabs- (spider crab). There were a paltry number of shorebirds actually on the shoreline - V. phalacrocorax (10 adults, 3j); a few juvenile dunlin, a Baird sandpiper. Small flocks of Aissa tridactyla visible offshore circling ice flows. Altogether a very pleasant evening. GRID 3 2 August 0700 - 0900 censused grid 3. Incredible weather - no wind, or only slight from E, 0% cloud, 40°. Also incredible dunlin densities: GRID TOTALS Somateria spectabilis 25 ha Pluvialis dominica a Calidris alpina j C. melanotos q j c. pusilla Microedoma himalayana j Ph. fulicarius q j Skovorouin pom. Calcorius lapponicus (INCREDIBLE, but close to the truth. 3.6 dunlin/ha, including adults and juveniles. Many of the adults occurred in a large, dispersed flock in the lower sections of the grid. They did move somewhat, but I had little difficulty keeping reasonable track of them. At one time I saw 21 in one unit (affluvial current pushed several small flocks together). Taken in concert with yesterday's results on Grid 2, it supports strongly the notion of a courtship movement of birds. We don't see much high densities further inland - nothing near them. TRANSECT 2 3 August worked on heli-tat on [illegible] transect 2. See daily list transects 6-10 4 August 0830 began censusing transects 380 all day, cold W wind, 100% low fog clearings as fine day wore on. As the transect summary shows, densities of several species have been changing since the last census, 31 July. In particular melanotos [illegible] and fulicarius [illegible] continue their decline. C. alpina adults remain at the
