Intra‐ and inter‐annual variation in gray whale body condition on a foraging ground

Creator:

Soledade Lemos, Leila, Burnett, Jonathan D., Chandler, Todd E., Sumich, James L., and Torres, Leigh G.

Abstract:

Baleen whales store energy gained on foraging grounds to support reproduction and other metabolic needs while fasting for long periods during migration. Whale body condition can be used to monitor foraging success, and thus better understand and anticipate individual‐ and population‐level trends in reproduction and survival. We assessed the body...

Estimating morphometric attributes of baleen whales with photogrammetry from small UASs: A case study with blue and gray whales

Creator:

Burnett, Jonathan D., Lemos, Leila, Barlow, Dawn, Wing, Michael G., Chandler, Todd, and Torres, Leigh G.

Abstract:

Small unmanned aircraft systems (sUASs) are fostering novel approaches to marine mammal research, including baleen whale photogrammetry, by providing new observational perspectives. We collected vertical images of 89 gray and 6 blue whales using low cost sUASs to examine the accuracy of image based morphometry. Moreover, measurements from 192 images...
