Are we vulnerable at APSH?

The saturation state of calcium carbonate minerals in sea water = Ωarag

The sweet spot for this parameter is thought to be < Ωarag = 1.5 but this varies with species and life stage..

Continuous Monitoring

(1) Early data: October 2013 to August 2014 Two distinct stressful Ω water masses; autumn freshets and cold winter water (−) anthroCO2 (Harris et al. 2013) Ωarag = 1.5 Average Ωarag = 1.55 ± 0.15; 43% < Ωarag = 1.5 Window of reprieve from stressful Ωarag gone at pCO2(atm) = 500 μatm IPCC RCP 8.5 predicts this level by 2040 Significant implication for growing Alaskan industry

“Putting an IOOS buoy in the water is like putting headlights

n a car. It lets us see changing water conditions in real time.”

SLIDE 14

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?

SLIDE 15

Village/Sampling Sites

SLIDE 16

The Sampling Kits

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