J Myers 1976 Journal Transects 8-9 Barrow Alaska 18-19 July (cont'd) the vegetation, once into the heart of the marsh, is Nodum II, Diapontia - Eriophorum angustifolium, with pure (or almost) stands of Eriophorum a. interspersed with a stand [illegible] by Diapontia, but with significant Arctophila and Eriophorum russeolum. Most of the substrate is very briquetate, and quite saturated, water gushing out even now in mid July as you walk across. Along the drier edge, and particularly where the snow bank lay, is a stand which probably belongs to Nodum II, dominated by Diapontia and Alpocurus, although the former predominates. Salix reticulata spreads extensively through this. Eriophorum angustifolium is also present, and in the same stand away from the snow bank area Poa is also present. The transition palustrina presents a problem in classification, as such zones often do, which I have resolved by creating a substand and deferred for final decisions until talking w/ P. Webber. It also occurs on transect 6 on the NE end of Gasline ridge, below the belt of Nodum II, and then again on transect 10 in units 0 and 1, in the same relationship with another belt of N-II. This transition and substand would therefore seem to be associated with low, wet + largely unpolygonized areas lying below Salix reticulata health in a zonation pattern along the sides of ridges. As for avian utilization goes, our data from Transect 9 show that it is heavily used largely by pectorals and red phalaropes, although no dunlin may occur in late breeding season. Transects 6-10 20 July Begun sampling the 50 ha of transects at 0850, finished by 1235. See transect account for details. Weather dominated by a light E wind, 98% high clouds, 42°. We seem to have recovered from the light rain showers of yesterday. Temperature down to a respectable 42° and decreasing during the morning.
