SPMyers 1977 Journal NARL, Barrow, Alaska 30 June 4:00 p.m. walked 6 of town to Nunavet Bay, after driving as far as we could along the road going SE from the airport. Path took us successively [illegible] until hitting the slopes of the bay's upper reaches, and we then followed the bay along its mouth slope to within 400 m of mouth into Chukchi Sea. A gorgeous day of sunshine, light wind, and 40° temperatures. Most of the habitat we traversed was comparable to that found within our transect/grid area, but near the bay it developed extensive uplands - successively sloping leads into the bay - covered with tundra not unlike unit (8,1) of T6. Vegetation is essentially the same, same that Dryas integrifolia is common, and a few Salix reticulata are scattered about. But the real difference is the extent of the uplands, with the sloping creek banks occupying many ha. of continuous land. Above the rim of the banks the tundra turned to generic polygonized ridge vegetation similar to unit (18,1) of T7 - Poa, Salix polaris. Well drained troughs. Bird life was reduced in density in most of the upland areas we traversed, especially on the sloping banks where only 2 species were detected, Baird and Buff- breasted Sandpiper (1 of each) in the adjacent polygonized uplands. C. pusilla, Calyptra, and Plovielin dominica appeared, but only the 1st of these was "numerous" and then specifically in our location near the edge of the sloping bank. Some pusilla were seen flying between upland polygonized areas down to the water's edge on the bay. We saw no pusilla before reaching the zone adjacent to the edge, even though some of the habitat we traversed was good mixed pond + polygon. This reaffirms Frank's contention that pusilla depend upon this sort of juxtaposition of habitat types. Gobs of Emeletus and P. fulviviridis moved through the lowland Carex marshes. 1 July Transects today: I ran 6-10 while Dave Shufford sampled 1-5. Weather 33° at 0600 rising to 41° by 1430 when we returned. Fog, NE wind, clearing by 1100 to a sunny, cloudy day. The tundra is drying, ponds receding, flowers emerging. Found blooming Potentilla today and one Papaver in flower. Birds are moving through. Large flocks of Plectropterus mixed with Black Phalarope and a few dunlin were wheeling over the tundra - up to 410 birds in a flock. Gooline Bridge was teeming w/ birds: 28 Pectorals, 17 Dunlin in 10 ha.
