NRDC Ocean Acidification Hotspots Map

The Natural Resources Defense Council (NRDC) has developed an online interactive map of ocean acidification implications on coastal communities. The mapping approach determines where the ocean chemistry is changing most rapidly, where vulnerable species are located, and where people who most depend on these species reside. The intersection of these factors reveals an elevated risk from ocean acidification.

See if your community is at risk of harm from ocean acidification.

These maps display the results of a study the NRDC conducted to identify which coastal communities in the United States are most vulnerable to ocean acidification. The analysis focuses specifically on the potential economic and social impacts to communities that derive benefits from shelled mollusk harvests, which are particularly threatened by ocean acidification.

Multiple map layers can be accessed from a regional or local level addressing each of: Chemistry, Shellfish, and People. 

This resource focuses on the economic and social impacts to communities that derive benefits from shelled mollusk harvests that are threatened by ocean acidification.  The "people" layer of the map allows users to visualize the communities that are most likely to be negatively impacted by threats to the mollusk industry, and to explore more specific indicators for sensitivity to acidification risks and adaptive capacity to respond to those risks. 

From the “People” layer, the user can see the resulting analysis of Social Vulnerability, Sensitivity, and Adaptive Capacity. Total social vulnerability ratings represents “the propensity to be harmed by the loss of shelled mollusks, based on the dependence on shellfish combined with the capacity of communities to adapt, prevent or prepare for ocean acidification.” Adaptive capacity is one of the components used to understand social vulnerability - whereas the adaptive capacity in this case is the ability to prepare for, cope with and respond to or recover from changes brought on by ocean acidification. This capacity is based on shellfish fishery diversity and economic diversity.
