Whale sanctuary on ‘Changing Seas’

The Hawaiian Islands Humpback Whale National Marine Sanctuary will be featured on PBS South Florida’s “Changing Seas” that premieres today.

“Vanishing Whales” takes a closer look at the humpback population that migrates between Hawaii and Alaska. Its decadeslong recovery from commercial whaling is considered a conservation success story. But when sightings of animals suddenly dropped, scientists in both locations began trying to understand what happened to the whales, according to a news release from the National Oceanic and Atmospheric Administration, which oversees the marine sanctuary.

“Humpback Health” delves deeper into the many mysteries that remain about these ocean leviathans. When in their Hawaiian breeding grounds, the humpbacks fast for an extended period, while expending energy on mating and giving birth. Now, for the first time, a team of scientists is making remarkable discoveries about how the whales’ body size and overall health change across the animals’ migratory cycle.

Both programs are available for viewing online today at changingseas.tv or on the “Changing Seas TV” YouTube channel.
