  • When we first detected hypoxia, we began to ramp up our monitoring efforts and in the last few years, we have helped to bring on a number of collaborators. We have done that by organizing bi-annual meetings for our scientific collaborators to coordinate plans for each field season and share research findings. This is the first step in informing public policy – the scientific community needs to be coordinated and studying the problem holistically. This is a plot of our hypoxia monitoring over the last 8 years. The size of the bubbles is the relative amount of sampling in each category (i.e., # sampling days).Collaborators:ROV surveys (Michael Donnellan, ODFW- current, David Fox and Hal Weeks, were past collaborators from ODFW)HAB: Pete Strutton from COAS. I believe that he’s funded for that work through NOAAMicrobial community: Steve Giovannoni from microbiologyLarval fish: Lorenzo Ciannelli from COAS (a seagrant funded project)Vibrio: Chris Langdon (at HMSC) Hake and groundfish: NOAA NMFSC
  • This issue has also been covered extensively by the regional and national media, and the PISCO program has staff dedicated to ensuring scientifically-sound materials are available to inform the community about hypoxia.We have developed outreach materials to help communicate the science of hypoxia and impact on the pacific NW.
  • The motivation for starting this consortium was that 10 years ago, ecologists had very little interactions with physics-oriented oceanographers on the high seas. Our goal to understand the key dynamics of the ecosystem along the U.S. West Coast required that we bring together marine ecologists, molecular and organismal biologists, and physical oceanographers. It also required that the science and data are expansive across time and space. We work in the productive, nearshore portion (<10 miles from shore) of the California Current Large Marine Ecosystem.
