Laurie Weitkamp, a fisheries biologist with the National Oceanic and Atmospheric Administration, will discuss the consequences of Pacific Ocean warming at the Corvallis Science Pub on Monday, March 14

Weitkamp, of NOAA’s Northwest Fisheries Science Center in Newport, specializes in the estuarine and marine ecology of Pacific salmon and the factors that affect their survival.

Science Pub is free and open to the public. It begins at 6 p.m. at the Old World Deli, 341 S.W. 2nd St., in Corvallis. The events are sponsored by OSU’s Terra magazine, the Downtown Corvallis Association and the Oregon Museum of Science and Industry.

In the spring of 2014, a body of water several degrees warmer than the surrounding ocean appeared in the Pacific off the Oregon coast. A year later, one of the largest El Niños in recorded history began forming at the equator and has been changing weather around the world.

Weitkamp will describe these two phenomena and their physical effects at sea and on land in the Pacific Northwest. She will also highlight the many changes observed in marine ecosystems from Alaska to Mexico during the last year.
