  3. Are we vulnerable at APSH?

  4. We have had good success with RKC… First Red King Crab Outplant 2013

  7. The saturation state of calcium carbonate minerals in sea water = Ω arag The sweet spot for this parameter is thought to be < Ω arag = 1.5 but this varies with species and life stage..

  9. Continuous Monitoring

  10. (1) Early data: October 2013 to August 2014 Ω arag = 1.5 (−) anthroCO 2 (Harris et al. 2013) Average Ω arag = 1.55 ± 0.15; 43% < Ω arag = 1.5 Two distinct stressful Ω water masses; autumn freshets and cold winter water Window of reprieve from stressful Ω arag gone at pCO 2(atm) = 500 μatm IPCC RCP 8.5 predicts this level by 2040 Significant implication for growing Alaskan industry

  12. An OA Lighthouse for the Shellfish Aquaculture Industry in the State of Alaska: Alutiiq Pride Shellfish Hatchery Wiley Evans Burke Hales Jacqueline Ramsay Jeff Hetrick Jeremy Mathis “ Putting an IOOS buoy in the water is like putting headlights on a car. It lets us see changing water conditions in real time .” - Mark Wiegardt, WCSH Photo by Jennifer Questel of Cape Hinchinbrook Lighthouse taken July 2015

  13. Site Specific Sampling since OA is localized in the near shore environment • what are the vulnerable sites for locally harvested shellfish? • Will recruitment diminish in those areas? • where are good out plant sites for vulnerable shellfish juveniles?

  14. Village/Sampling Sites

  15. The Sampling Kits The kits contain: Protocols, bottles, caps & cappers, paint pens, thermometers, sample logs, and fixative.

  16. Discreet Sampling for Carbonate Saturation State of Sea Water

  17. Certified Reference Material The gold standard

  18. This slide will describe the dosing lab

  19. Special thanks to supporters IOOS? Does burke have a logo?
