  When you stop to think about it, we know less about the oceans of Earth than the space immediately surrounding the planet.

Because unlike space, we can't see through the ocean or use satellites to explore it. 

That's why the Ocean Observatories Initiative started up... to place sensors off both coasts of the United States, to track a broad array of information. 

A crew from Oregon State University recently placed the final sensor in the Pacific.

Recent discussions of the warm-water "Blob" in the Pacific may have obscured previously existing concerns about ocean health.

Like the increasing level of acidity in the ocean, and the more frequent appearance of low-oxygen zones (hypoxia). 

The West Coast Ocean Acidification & Hypoxia Science Panel brings together top minds from the West Coast State and British Columbia to come up with ideas for addressing the ocean issues. 

The panel presents a progress update at a meeting in Sacramento next week (July 29), with several reports due this fall. 

Returning The Favor: "Saved By The Sea"

We'll be celebrating Earth Day in the near future.  Journalist, documentary producer, activist, and scuba diver David Helvarg once observed that our celebrations seemed to stop at land's end, and did not include the oceans. 

He aims to correct the oversight in his book Saved By The Sea

Helvarg recounts his many experiences--plenty bad with the good--in the Earth's oceans in this memoir. 

Answers For Oysters With Shell Trouble

It's a tough life for a newly hatched oyster.  Shellfish have 48 hours after hatching to form a shell, or they die. 

And current ocean conditions make it harder for the shellfish larvae to make shells. 

Ocean researchers including George Waldbusser at Oregon State just studied the factors. 

The increasing acidity of the oceans is one, but there are others to take into account. 

California U.S. Representative Lois Capps has asked for a moratorium on offshore fracking until there's more study. In a letter to the Interior Department and the U.S. Environmental Protection Agency this week, Capps says she wants the federal government to conduct a study of fracking's impacts to the marine environment.

A recent report by the Associated Press documented at least a dozen instances of hydraulic fracturing in the Santa Barbara Channel, site of a disastrous 1969 oil platform blowout that spurred the modern environmental movement.

An emergency effort has begun to remove millions of gallons of toxic liquids from an abandoned pulp mill that poses a pollution threat to Humboldt Bay.

The Eureka Times-Standard reports that the U.S. Environmental Protection Agency plans to remove more than 4 million gallons of pulping liquors from the old mill site.
