View Full Version : Oceans Are Losing Oxygen

A friend sent me a couple of interesting articles this week.

The first one is another another sad problem in the ocean in addition to climate change, and acidification; it is low oxygen levels. I know these zones are occurring up in Oregon too and they kill anything that can't get away fast enough like crabs. They are termed 'dead zones'.

Marlin and sailfish are the oceans’ perfect athletes. A marlin can outweigh a polar bear, leap through the air, and traverse the sea from Delaware to Madagascar. Sailfish can outrace nearly every fish in the sea. Marlin can hunt in waters a half mile down, and sailfish often head to deep waters too.

Yet in more and more places around the world, these predators are sticking near the surface, rarely using their formidable power to plunge into the depths to chase prey.

The discovery of this behavioral quirk in fish built for diving offers some of the most tangible evidence of a disturbing trend: Warming temperatures are sucking oxygen out of waters (http://micheli.stanford.edu/pdf/oceanographicandbiologicaleffectsofshoaling.pdf) even far out at sea, making enormous stretches of deep ocean hostile to marine life.

“Two hundred meters down, there is a freight train of low-oxygen water barreling toward the surface,” says William Gilly (http://www-marine.stanford.edu/gilly.html), a marine biologist with Stanford University’s Hopkins Marine Station, in Pacific Grove, California. Yet, “with all the ballyhoo about ocean issues, this one hasn’t gotten much attention.” ...

Cool pic in the link shows a marlin hunting Sardines. Sad to say that Sardines are on the decline on the West coast and the commercial season was just shut down early at the PFMC meeting in Rohnert Park this week.

Yes....Very interesting. I watched a program about six months ago on either the Nat/Geo channel, or Discovery. It was very similar to these articles.

I've said it before........Something very serious is brewing with Mother Nature, And I don't think We're going to like it.

There's a program airing on PBS, 5/13/05 @ 9:00 pm called "Lethal Seas". Not sure if it has anything to do with these "Dead Zones" but should be very interesting none the less.

Yesterday on the channel 3 news, they were talking about one of these "Dead Zones" 20 miles off the California coast. They said the oxygen level in this particular zone is about half of what it should be.

Yea on the Cordell Banks.

You guys got any web links for that California dead zone? I didn't hear about it and can't seem to google it up.

Thanks for that, rnp.

I wonder how widespread it is outside the Golden gate? Seems like salmon catches have been rather sporadic and bait out there is kinda few and far between. Perhaps it is related?

Glad someone is monitoring the situation though.

Best,
