Effect of underwater seismic surveys on molting male Long-tailed Ducks in the Beaufort Sea, Alaska
Large numbers of Long-tailed Ducks (Clangula hyemalis) (10 000 – 30 000) undergo a postnuptial wing molt along barrier islands of the Beaufort Sea, Alaska. To investigate the potential effects of underwater seismic activities on this species, we monitored the number and diving behavior of molting Lo...
