Location and number of Walrus counted during surveys or incidental sightings (in order presented in text): A — Southampton Island, Coats Island and Evans Strait; B — Northern Foxe Basin; C — Southeast Baffin Island; D ~ Central High Arctic; E — Salisbury, Nottingham and Mill Islands; F — Western Foxe Peninsula; G — Ottawa and Spicer Islands; H — Cape Henrietta Maria; I — East coast of Baffin Island; J — Northwest Greenland. In northern Hudson Bay, all known uglit of the Southampton-Coats Island area were surveyed by aircraft in July and August of 1976 and 1977. Haul- out sites were counted visually and photographed. The adjacent pack ice of Evans Strait was also surveyed by flying parallel transect lines spaced approximately 15 km apart. The largest total number counted in a day both at haul-out sites and on Evans Strait transects was 2350 on 26 July 1977 (A. W. Mansfield, DFO, Arctic Biological Station, Ste-Anne-de-Bellevue, personal commun- ication). No estimate of population size was derived from these counts. In northern Foxe Basin, observers counted 2716 Walrus during a helicopter survey along the edge of the pack ice on 19 and 20 of August 1983 (Orr et al. 1986). This reconnaissance survey covered only a small portion of northern Foxe Basin. It cannot be used to estimate population size. Along the southeast coast of Baffin Island, a number of small uglit were located during summer and fall surveys in 1977 to 1979 (MacLaren-.
