Almost 25 years ago, the world's attention was rapt on three gray whales stranded by encroaching sea ice off the coast of Alaska and the effort to free them.
Dave Withrow, a marine mammal biologist with the National Oceanic and Atmospheric Administration, was called in to help with the rescue, which had to contend with frigid temperatures, persistently freezing ice and coordinating a wide range of groups that wanted to help with the effort.Withrow spoke about his experiences during the rescue, called Operation Breakthrough" in a recent NOAA interview.
