Hypoxia Research Opportunities & News

     Kipp Shearman and Jeremy Childress, in cooperation with Oregon Dungeness crab fishermen, have added a dissolved oxygen (DO) component to their program (Fishermen in Ocean Observing Research) for the summer 2009 season. Five DO units have been attached to crab pots and deployed south of Newport near the PISCO Seal Rock line with one sensor located at the 10m isobath, three at 30m, and one at 50m. A photograph showing how the DO sensors are attached to the crab pots is available HERE. From approximately June 1 to August 15, data will be collected at 10 minute intervals from each location and will be available later this summer at www.Or.FIOOR.org.

     Greetings from the Wecoma and the NH line off Yaquina Head where we have been sampling since Saturday, June 6th. This is the second of four cruises for our project: Instrumentation for determining benthic oxygen exchange rates by eddy correlation with coordinated studies of the Oregon shelf. The sea has been glassy calm and turbidity profiles, water samples, bottom photos and sediment core tops show that the bottom boundary layer is thick with phytodetritus especially along the 50-m isobath. Two time-lapse photos from our eddy correlation lander at 82 m are available HERE and HERE. The bottom is not clearly in focus because of all the material in the water column, but you should be able to make out flatfish (likely Pacific sanddabs).      Posted by Craig Risien for Clare Reimers: 11 June 2009

The geographic extent of hypoxia in 2006 and 2007. Light blue shows the extent of hypoxia (<1.4 ml/l) and purple shows the region of severe hypoxia (<0.5 ml/l). Waters closest to the shore remain high in oxygen due to breaking waves. Dots represent sampling sites. Data made available by PISCO and NOAA-Fisheries, NWFSC.
