Paving a path for the shellfish industry to adapt to ocean acidification
Our primary objective is to evaluate the vulnerability and adaptation pathways of shellfish dependent stakeholders in the Pacific Northwest (PNW) to the hazard of ocean acidification (OA). We are developing an interactive, web-based geovisualization tool to map shellfish stakeholders’: 1) current an...

Our primary objective is to evaluate the vulnerability and adaptation pathways of shellfish dependent stakeholders in the Pacific Northwest (PNW) to the hazard of ocean acidification (OA). We are developing an interactive, web-based geovisualization tool to map shellfish stakeholders’: 1) current and future exposure to OA, 2) socio-economic and cultural sensitivity to OA from dependence on four shellfish species with varied sensitivity to OA, and 3) adaptive capacity to prepare for or avoid harmful consequences of OA. We define exposure as the magnitude and frequency of undersaturated, high pCO2, low pH water - OA “hotspots” - coinciding with shellfish growing areas. To visualize where and when OA hotspots occur, our map includes an interactive time-slider for users to view monthly carbonate chemistry projections from a published model output of the California Current through 2050.
