The bright orange flags stacked on the deck of the Pacific Surveyor, a 56-foot research vessel moored at the Port of Siuslaw, are not new-fangled crab pot markers. Instead, they mark underwater acoustic receivers, strategically placed near the ocean floor to pick up sound from which researchers hope to learn the habits of a particular species of fish in a particular section of ocean.

“It turns out that the green sturgeon’s migration route is right through the proposed wave energy site just north of the Umpqua River,” said Al Pazar, owner of the research vessel who, along with a crew, anchors and marks the listening devices and then routinely services them. When retrieved, the collected data is downloaded to computers for analysis.
