JPNayens 1975 Journal Grids 2,3 Barrow, AK 20 August Began sampling #2 at 0800 after spending 30 min walking thru Trygata along N side of Joka Creek. The totals reflect an unexpected development, at least as far as the achieved definitions are concerned: we have been invaded by juvenile Limnodromus scolopaceus. However they are appearing only in the upland (i.e. inland) areas, not along in the littoral zone. Weather this a.m. 38°, light NE wind, 10 low clouds (ret see fog).

We arrived ~1500, established ourselves in NARC camp and then went out onto transects established previously along the Kuk river, inland from the Wainwright airport. The tundra between the airport and the Kuk is broadly polygonized tundra sloping gently down toward the Kuk, at which point the slope breaks sharply in a 10-20 ft bank. Deep troughs sometimes a meter or more wide, polygons 50-100 cm high, a few higher. Vegetation on the mounds is generally a Salix polaris/Arcticum with considerable Enniogdron vaginatum tussocks. A rosette which neither R.G. nor I recognized substituted for Potentilla vivida cases. Troughs were Diplopoda and Eriophyllum, ponds had stands of Arctopilus. This series of high polygon extends several kilometers along the ridge separating the Chukchi Sea from the Kuk (which at this point is flowing parallel to the ocean). Walking along the creek, there are occasional large expanses of low center polygons and ponds. One side, at the northern end of our walk ~1.5 km straight north from Wainwright, the Kuk river near the airport is a boring, small-gravel beach which is imperceptibly riverine, but most definitely an estuary. No birds were foraging along the first transect, while some along this beach ~1 km from the point where we intercepted the Kuk
