Geophysical Studies Along Northern Ellesmere Island

Abstract

During late June 1954 the writer and G.F. Hattersley-Smith (Ellesmere Ice Shelf Expedition) made 19 line soundings, three hydrographic stations, and took 13 Phleger bottom core samples along the Ellesmere coast between Markham and M'Clintock Bays (approx. 83 00-15 N 71-77 W) In late summer, 25 seismic soundings (19 successful) were attempted through the ice shelf from Ward Hunt Island to Cape Discovery (approx. 74-77 W). Some results of the bathymetric program are given, also temperatures and salinities, and magnetic declinations. Soundings data are supplemented by those of R.G. Marvin on the Peary Expedition 1906 in the same area. Marvin's work is discussed by V.C. Bushnell, q.v.
