Ocean planning would bring billions in benefits. A new study found that forming a coordinated plan for ocean use ahead of time could prevent more than $1 million in losses to fishing and whale watching industries, and generate over $10 billion for the energy industry, by strategically addressing industrial ocean development and minimizing conflicts between sectors. Massachusetts, having already implemented such strategies, serves as a model. [The Huffington Post; PNAS]

Salmon fishing quotas raised amid predictions of increased runs in OR and CA. The Sacramento and Klamath Rivers are anticipated to see the highest salmon returns in years. Some threats to salmon remain and further fluctuations can be expected. [Pacific Fishery Management Council; Mercury News]

Seal disease spreading to polar bears? A significant number of polar bears in the Beaufort Sea region have been found with skin lesions and hair loss, symptoms of a disease that has been taking a toll on seals and walruses. The polar bears seemed otherwise healthy, and scientists are still working to understand whether and how the incidents are connected. [USGS]

The Arctic and Antarctic are changing faster than thought. A report that compiled data from thousands of scientists in 60 countries provided a new, comprehensive scientific view of the poles. Report co-chair Julie Brigham-Grette said, “Earth has gone through this before, and some past warm cycles have been extreme, but we as humans have never seen anything like it in our 10,000 years on the planet.” [National Academy of Sciences; UMass Amherst]

Fukushima radiation study detects elevated but not harmful levels in Pacific. Cesium isotopes have recently jumped to higher levels than usual, and while scientists say they are below levels of concern for humans and wildlife, the question remains whether they are accumulating in larger amounts in seafloor sediments.
