Hello everyone, 
My coauthors and I are pleased to announce the publication of our new paper
on long-term survival of humpback whales radio-tagged in Alaska from 1976
through 1978.

ABSTRACT
Invasive tags designed to provide information on animal movements through
radio or satellite monitoring have tremendous potential for the study of
whales and other cetaceans.  However, to date there have been no published
studies on the survival of tagged animals over periods of years or decades.
Researchers from National Marine Mammal Laboratory and the Woods Hole
Oceanographic Institution tracked five humpback whales with implanted radio
tags in southeastern Alaska in August 1976 and July 1977, and tracked two
humpback whales in Prince William Sound, Alaska, in June 1978.  All seven of
these individually identified humpback whales were re-sighted at least 20
years after first being tagged, and five of the seven have been observed for
more than 30 years; some of them are among the most resighted humpback
whales in the North Pacific.  Photos of tagging sites taken during and
subsequent to tagging operations show persistent but superficial scarring
and no indication of infection.

These pioneering field studies demonstrated both long-term survival of the
whales and the short-term effects of deploying radio tags, which at the time
were larger and more invasive than those typically used today.
