Warning Buoy Network Protects Right Whales
coondoggie alerts us to a story that is actually a few weeks old now about a network of sonic buoys to listen to right whales, in order to warn ships away from them. On April 10, 22% of the known population of right whales in the world — 79 out of 350 — were gathered at Stellwagen Bank, off of Massachusetts, to feed on a bumper crop of the tiny crustaceans called copepods. The network of smart buoys helps to protect the whales from the roughly 1,500 ships per year that go through this feeding ground on their way to and from Boston.
DNA studies apparently show that the Right Whales around Australia and New Zealand are not a single species, as had been thought, but two genetically distinct species. This has been found to be the case of other cetaceans - Hector's Dolphin, I think, is another where they had to re-estimate populations because there were multiple species counted as a single one. I don't know if DNA studies have been carried out on the populations of Right Whales of the US coast. Because there are multiple species involved, though, the term "Right Whale" only refers to a physiological description, not a biological one, and should go the way of other dead labels. Problem is, labels are used to define what is protected, so doing that might be harmful by removing essential protections, even though it should be helpful by allowing an accurate description of what is in the sea.

If the US Navy's extra-powerful sonar is jamming long-distance whale communication and destroying whale hearing, as has been claimed, then maybe they DO need free speech protections.

Whales already do this. They can hear ships engine noise from a long way off and whales with experience of being hunted (the ones that get away, if you like) will avoid the sound. Thus the Japanese commercial whaling (scientific, my arse) buggers things up for the multi-million dollar whale watching industry in Australia and New Zealand, because the whales can't tell the difference. Problem is the ships designed to hunt them are faster than the whales and they don't get tired. The whales dive to avoid them, but they have to come up for air sometime. If whaling is such a tradition let them do it the traditional way, in open boats with people rowing. Otherwise it's just a scam perpetrated on a world too gutless to stand up to them.
If my call is important, why am I talking to a recording?
I live on the Outer Cape in Cape Cod Massachusetts. Herring Cove Beach is about 7 miles from my home. You can just drive to the beach and see them off shore. Now, the bulk of the whale are off shore and can't be seen, but there were about 40 there on Saturday. The whale watch boats are often kept at bay by the Provincetown Police, but even if the police aren't there, the boats do the right thing and stay a bit off. I've seen countless dolphins in a single field of view of my binoculars.
If you are in the area, you really should go see this. Bring the best binoculars you can, but even if you don't have any, you might see tens of blows per minutes. Long time locals suggest that the shore whales will disappear once the fast ferry starts up, which is in about 2 weeks.
It is truly amazing. I can't imagine what it is like off shore.
