March 1st 2017 TILLAMOOK, Ore. – The Whiskey Creek Shellfish Hatchery is quietly tucked away off the Netarts Bay in Tillamook. As the state’s only shellfish hatchery, it’s a large part of the oyster industry in the region. Alan Barton is the Production Manager at Whiskey Creek. He’s worked

Development and application of foraminiferal carbonate system proxies to quantify ocean acidification in the California Current
Published 22 February 2017 The oceanic uptake of anthropogenic carbon has mitigated climate change, but has also resulted in a global average 0.1 decline in surface ocean pH over 20th century known as ocean acidification. The parallel reduction in carbonate ion concentration ([CO32-]) and the saturation state of seawater (Ω)
Transcriptomic responses to seawater acidification among sea urchin populations inhabiting a natural pH mosaic
Published 6 February 2017 Increasing awareness of spatial and temporal variation in ocean pH suggests some marine populations may be adapted to local pH regimes and will therefore respond differently to present-day pH variation and to long-term ocean acidification. In the Northeast Pacific Ocean, differences in the strength of coastal
New ocean, new needs: Application of pteropod shell dissolution as a biological indicator for marine resource management
February 3 Pteropods, planktonic marine snails with a cosmopolitan distribution, are highly sensitive to changing ocean chemistry. Graphical abstract shows pteropod responses to be related to aragonite saturation state, with progressing decrease in Ωar causing deteriorating biological conditions. Under high saturation state (Ωar > 1.1; zone 0), pteropods are
Mechanistic understanding of ocean acidification impacts on larval feeding physiology and energy budgets of the mussel Mytilus californianus
24 January 2017 Ocean acidification (OA)—a process describing the ocean’s increase in dissolved carbon dioxide ( pCO2) and a reduction in pH and aragonite saturation state (Ωar) due to higher concentrations of atmospheric CO2—is considered a threat to bivalve mollusks and other marine calcifiers. While many studies have focused
