(18-23 June) by technician L. Shults in connection with another<br />

related project.<br />

The shores <strong>of</strong> Kotzebue Sound from Sheshalik to Point Hope and<br />

from Cape Espenberg to Wales were surveyed by L. Shults via<br />

chartered aircraft from 16 to 25 <strong>July</strong>. The area covered is shown<br />

in Fig. 3. Several landings were made on the beaches <strong>for</strong> closer<br />

inspection and collection <strong>of</strong> diagnostic samples from some <strong>of</strong> the<br />

carcasses.<br />

III. Results<br />

One hundred thirty titles <strong>of</strong> papers dealing with diseases,<br />

parasites, pathology and natural mortality <strong>of</strong> marine mammals<br />

have been accumulated thus far, and the search and review<br />

procedures are continuing.<br />

A first draft <strong>of</strong> an autopsy manual was developed <strong>for</strong> use and<br />

critique by project personnel during this quarter's field<br />

activities. Several modifications were indicated and will be incorporated<br />

into a second working draft in the next quarter.<br />

The Alaska Peninsula survey covered about 620 km (385 mi) <strong>of</strong><br />

coast, on which were found the remains <strong>of</strong> 12 whales (all<br />

apparently very young gray Eschrichtius gibbosus, and minke<br />

whales, Balaenoptera acutorostrata), 16 adult walruses (Odobenus<br />

rosmarus), 10 young and adult hair seals (Phoca spp.) and 3<br />

adult sea otters (Enhydra lutris). About one-fourth <strong>of</strong> these<br />

were old, dried and tattered remains left from previous years;<br />

three-fourths were judged to have stranded no more than 3 months<br />

prior to the survey. The degenerate condition <strong>of</strong> most <strong>of</strong> the<br />

latter precluded useful autopsy.<br />

The Kuskokwim Bay supplement which amounted to about 83 km<br />

(51.5 mi), yielded no carcasses at all, and the C. Pierce-C.<br />

Newenham segment <strong>of</strong> about 8 km (5 mi) yielded only 1 fresh<br />

carcass <strong>of</strong> an adult male Steller's sea lion (Eumetopias jubatus)<br />

and an assortment <strong>of</strong> much older remains <strong>of</strong> walruses (2 adult,<br />

2 subadult males), harbor seals (Phoca vitulina, 2 adults) and<br />

whales (1 each <strong>of</strong> gray and minke, I killer whale, Orcinus orca<br />

and 1 giant bottle-nosed whale, Berardius bairdii).<br />

About 267 km (167 mi) <strong>of</strong> the coast <strong>of</strong> St. Lawrence Island were<br />

surveyed, yielding 36 whales (30 grays and minkes, 4 bowheads,<br />

Balaena mysticetus and 2 finbacks, Balacnoptera physalus),<br />
