Declining oxygen in ocean could drive fish away

A new report from scientists at the National Oceanic and Atmospheric Administration and Oregon State University sheds new light on how ocean “dead zones” impact Northwest fisheries, according to The Oregonian. The areas of low oxygen within the ocean are expected to expand with climate change. Some fish, including spotted ratfish and petrale sole, will be driven away from low-oxygen waters, while others such as Dover sole and greenstriped rockfish have higher tolerance for low-oxygen conditions. The increasingly oxygen-starved ocean could mean changes ahead for the distribution of fish off Oregon’s coast.

Portland’s controversial new sewer building is costing birds their lives. The Oregonian’s Brad Schmidt reports some 27 birds have crashed into the Columbia Building since October, with at least eight of them dying. Concerned raised by the Audubon Society of Portland have led city employees to begin documenting the crashes so they can fix the problem. The likely culprit: 16 large windowpanes that make up the building’s backside, and face a bird haven.

A dry winter with little snowpack has left the Rogue River stunningly low, The Oregonian’s Terry Richard reports. “I saw the difference in the Avenue of the Boulders, just downstream from Prospect and the Rogue Gorge,” Richard wrote. “I took a photo on Sunday of this year’s low water and used one taken from the same place, the Mill Creek Drive bridge, in 2008, for comparison.” The difference, Richard said, “may make you want to save every drop of water that you can.” A public hearing Tuesday on the Port of Seattle’s decision to house Shell Oil’s Arctic drilling fleet included more than three hours of public testimony from dissenters. Earthfix reports hundreds of people packed the meeting at the SeaTac airport, voicing their environmental and safety concerns with the contract. The lease is expected to generate up to $28 million for the port. Environmentalists have already moved to sue.
