Warmth-induced algae blooms theory debunked
The Gulf of Alaska waters have been warm lately. A working hypothesis was that the whales were dying from domoic acid, which is a toxin produced by warmth-induced algae blooms. This did not seem entirely implausible, since the whales share similar eating habits. Nevertheless, this hypothesis was ruled out after test results taken from a partially decomposing fin whale carcass came back negative.
