JP Myers 1976 Journal Barrow, Alaska 4 June (cont'd) Beginning at 1445 I covered transects 6-10 while RG did #5. total of 169 minutes spent on transects - see summary for detailed results. Overall totals: 50 ha; 169 minutes (not including #5) density/ha Calidris alpina 8 .16 C. fuscicollis 1 .02 C. melanotos 87 5 .01 C. melanotos chance 8 = .05/min Stercorarius pomarinus 5 .01 Calcarius lapponicus 34 .68 Plectrophenax nivalis 7 .14 Walking back from the end of transect 10 I followed the south side of beach ridge as it contours south of Central Marsh Slough, finding another fox den along the way. See arctic fox spp. accent Cryo2 5 June p.m. - tracked C. melanotos after Rans had spent a.m. cursing. It reported a decline in # of melanotos #7 from previous days, and the evidence from tracking suggests that to be the case. Tundra is quite large compared to last year, with tundra areas being on the order of 12 ha. See tracking accent; see melanotos spp. accent. But of interest was the influx of P. alpina, as several 78 had multiple 99 in their territories. Alpina is displaying constantly now; I saw many aerial chases, wing-ups, etc. A few pisilla moving about but not in heavily yet. The jaycor pair occupying most of Cryo2 on 3 June (see journal) appears to have contracted its area, with another pair moving up to the high (unmarked) (8-10, y) zone. Melt-off records on grids 2 and 3 report (taken by RG this a.m.) a steady but unevenly distributed pattern. The strip along Grid 2 by Gao will Road has almost entirely melted. Overall melt-off average snow cover # was 72 and 86% for 2 and 3 respectively. Gaelene Ridge, Barrow, 6 June A glorious clear early morning with almost no wind enticed me into a taping foray, wandering along gaelene ridge with the Dan Gibson Parabolic Special, trying to cooy
