After three weeks of scanning and sampling for methane seeping out along the Cascadia Subduction Zone, researchers aboard the Nautilus pulled into the Port of Astoria on Friday with their findings. Tamara Baumberger and Bob Dziak are quoted.
Researchers listen to methane bubbles off Oregon coast
CORVALLIS, Ore. - A research team has successfully recorded the sound of methane bubbles from the seafloor off the Oregon coast using a hydrophone, opening the door to using acoustics to identify – and perhaps quantify – this important greenhouse gas in the ocean. Bob Dziak is quoted.
Snapping Shrimp 'Dinner Bell' May Tell Gray Whales When to Eat
