Summary

Abstract: Researchers from NMML's Cetacean Assessment and Ecology Program
conducted the line transect aerial surveys for harbor porpoise and Dall's

from Cape Suckling to Unimak Pass), Prince William Sound, and Shelikof Strait.
Surveys were conducted from a NOAA Corps DeHavilland Twin Otter, flown at an
