dc.description.abstract The ocean uptake of anthropogenic CO2 has shoaled the aragonite saturationhorizon in the California Current Ecosystem, but only a few studies to date havedemonstrated widespread biological impacts of ocean acidification under present-dayconditions. Pteropods are especially important for their role in carbon flux andenergy transfer in pelagic ecosystems. In the California Current Ecosystem,conditions are becoming increasing unfavorable for sustaining shell maintenancebecause of enhanced dissolution. Our results show a strong positive correlationbetween the proportion of pteropods with severe dissolution and the percentage ofthe water column that is undersaturated with respect to aragonite. From thisrelationship, we are able to determine the extent of dissolution for the pre-industrialera, 2011, and 2050. Our calculations show that dissolution has increased by 30%since the beginning of the industrial era, and could increase to 70% by 2050.Although dissolution is occurring in most of the investigated pteropod species,some species have changed their daily vertical distribution pattern by migrating toupper supersaturated waters to avoid corrosive waters, a potential indication of anadaptation strategy to ocean acidification. Preliminary analyses of calcification andrespiration rates demonstrate that part of the coastal pteropod population is alreadyunder increased effect of ocean acidification and hypoxia. -
