The 2017 Integrated Ecosystem and Pacific Hake Acoustic-Trawl Survey began on June 22, 2017 after a 7-day delay due to generator issues on the NOAA Ship Bell M. Shimada. The survey will be conducted June 22 through September 13, 2017 by the NWFSC FRAM Fisheries Engineering and Acoustic Technologies Team (FEAT) and Department of Fisheries and Oceans-Canada (DFO). The Integrated Ecosystem and Pacific Hake Acoustic-Trawl Survey is the sole source of fisheries independent data used by stock assessment scientists to evaluate the status and trends of Pacific Hake (Merluccius productus). This stock is jointly managed through the US-Canada Pacific Whiting Treaty.
Follow the survey adventures live in this blog as the FEAT scientists conduct survey operations from Point Conception, CA to the US-Canada border and on to Dixon Entrance at the north end of Haida Gwai’i!. See what they are seeing acoustically, learn about oceanographic and zooplankton sampling that helps our scientists better understand what hake contribute to the California Current Large Marine Ecosystem and ensure that harvest management has a strong scientific basis.
The FEAT Team calibrated the acoustics systems off shore of Newport, OR overnight June19-20. This was the first time we calibrated using dynamic positioning (DP) rather than anchoring. This successful calibration was important since there are limited anchorages along the west coast where a calibration may be conducted. Having the ability to calibrate using DP opens up our options for where and when we may calibrate the vessel systems.
The survey is a joint effort by NMFS and DFO-Canada conducted in five two-week legs onboard the NOAA Ship Bell M. Shimada (6/15/17- 9/13/17) and two two-week legs on the DFO chartered F/V Nordic Pearl (8/15/17 – 9/11/17). The FEAT Team consists of: Alicia Billings, Dezhang Chu, Julia Clemons, Steve de Blois, Larry Hufnagle, Sandy Parker-Stetter, John Pohl, and Rebecca Thomas. Additionally, we are pleased to have a number of scientists from other groups divisions, NOAA headquarters, NOAA's Teacher at Sea Program, and Universities assisting in the Wet Lab and with other projects during the 5 survey legs. This group consists of: Erika Fruh, Jamie Hale, Max Van Oostenburg, Anthony Odell, Jason Eibner, Heather Rippman, Garima Raheja, Haley Wunderlich, Monica Baze, Wu-Jung Lee, Phillip Bizzell, Lance Sullivan, Erika Smith, Brad Rhew, Alex Islas, Lance Kruzic, Hilarie Sorensen, Olivia Blondheim, Tracy Barry, Toby Mitchell, Jody Stecher, Michael Lewis, Liz Allyn, Chelsea O’Connell-Barlow, and Lynne Scamman. On the Canadian side the premier DFO Team is: Jackie Detering, Stephane Gauthier, Chris Grandin, Lu Guan, Shani Rousseau, Ben Snow and Chelsea Stanley.
