It never fails… some equipment will fail

Jul 22, 2013 | Gulf of Alaska Project | 0 comments

by Wyatt Fournier

As we learned from Russ in earlier posts, equipment failures are just another part of a research survey and we will have our share.

The Northwest Explorer is rigged with a 3rd wire that connects to a sensor mounted on the head rope of our trawl net.  This sensor allows us to measure the width and depth of the net as it fishes through the water column.  This is fairly simple when fishing at the surface but when Dave sees an acoustic target and wants to fish a mid-water trawl, this sensor is extremely important.  This sensor failed two days and has been restricting our ability to tow at depth.  A replacement was sent by Air Cargo to the nearest airport, back in Sitka.  We steamed towards the coast over night and this morning anchored up outside the harbor.  Luke, the deck boss, and I took the skiff into town to retrieve our package which Liz McKenzie had generously picked up from Air Cargo.  Thanks so much Liz!
Adam maneuvered the NW through the Whitestone Narrows and Neva Pass to save time allowing us to get back on the sampling grid before noon.

    WHo we are
    GENERAL INFO

    Established in 2001, NPRB is a marine research organization that supports pressing fishery management issues or marine ecosystem needs.

    REPORTS & PUBLICATIONS

    More than 600 peer-reviewed publications have been produced through NPRB-funded research. Browse our library and our reports here.

    LEADERSHIP

    NPRB comprises a 20 member Board, representing Federal, State, and other entitites while receiving advice from Science and Advisory Panels.

    PARTNERSHIPS

    Looking to partner with NPRB? NPRB welcomes partnerships to co-fund research in areas of common interest and across its programs.

    OUTREACH & ENGAGEMENT

    NPRB communicates and engages with a broad and diverse set of Alaskan stakeholders and audiences, from coastal communities to academia.

    STAFF

    NPRB staff support the Board, Science, and Advisory Panels for funding decisions, science priorities, recommendations, and program management.

    Funding Available

    The Core Program offers year-round funding with flexible rolling submission options.

    SUBMIT YOUR RESEARCH PRIORITIES

    NPRB staff begins developing draft research priorities for the Core Program in late July and August. Submit before July 2nd to be considered for the current year’s RFP development. 

    Our Programs
    INTEGRATED ECOSYSTEM PROGRAMS
    SCIENCE FOUNDATION

    NPRB maintains scientific programs designed to address pressing fishery management issues and Alaska marine ecosystem information needs.

    CORE PROGRAM

    NPRB supports a competitive, peer-reviewed annual request for proposal (RFP) process dedicated to marine research in Alaskan waters.

    The Arctic Integrated Ecosystem Reserach Program looked at how physical changes in the ocean influence the flow of energy through the marine food web in the Bering Strait, Chukchi Sea, and western Beaufort Sea from 2017-2021.

    OUTREACH PROGRAM

    Supporting science communication, engagement, outreach, and education initiatives for all our research programs.

    LONG-TERM MONITORING

    This program supports new or existing time-series research that enhance the ability to understand the current state of marine ecosystems.

    The Bering Sea Project, a partnership between the North Pacific Research Board and the National Science Foundation, sought to understand the impacts of climate change and dynamic sea ice cover on the eastern Bering Sea ecosystem.

    INTEGRATED ECOSYSTEM RESEARCH

    These are large-scale interdisciplinary ecosystem-based programs, requiring multiple agency coordination, collaboration, and investigation.

    GRADUATE STUDENT RESEARCH AWARDS

    NPRB supports next generation scientists, researchers, and resource managers to further their studies in relevant fields of marine science and to our mission.

    The Gulf of Alaska Project tested three main hypotheses about the survival and recruitment of five focal groundfish species (Pacific cod, Pacific ocean perch, walleye pollock, arrowtooth flounder, sablefish) during their first year of life.
