During the course of our research on walruses hauled out near Point Lay in early September, USGS obtained aerial video footage of the walrus aggregation. This footage was taken from an altitude of 4,000' with a Cineflex camera by Daniel Zatz, of Zatzworks, on contract to USGS for this work. We are exploring the potential of this type of video for enumerating the numbers of walruses hauled out, as well as the sex and age composition of the herds. This first effort was a pilot to test methodology. Recognizing the broad public interest in seeing what is going on at Point Lay right now, we have arranged to make the video publicly available. Please distribute as you see fit.
