On protecting whales

Here’s something from National Geographic: Bubble Curtains: Can They Dampen Offshore Energy Sound for Whales?

In other whale-related news, the Tyee posted this the other day: Appeal court upholds ruling on protection of orca habitat

A federal appeal court ruled yesterday that the Department of Fisheries and Oceans failed in its legal responsibility to protect habitat for orcas, the sleek, black and white killer whales that swim off the coast of B.C. (…)

  1. And another bit of research that has just come out, related to the effects of sound on whales…a study of stress hormones in whale poop (located by whale-poop-sniffing-dogs, Gabriolan!) has found that these stress indicators dropped sharply when ship traffic on the east coast was virtually shut down after 9/11 and then increased again when ship traffic resumed. In other words, whales are stressed by ship traffic, probably mostly the sound of ships.
