Name: St. Croix Degree Heating Weeks (Degree Heating Weeks above Maximum Monthly Mean)

Display Field: HABITAT

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: Degree Heating Weeks were calculated by summing the positive anomalies of the modeled SSTs above the NOAA CRW CoralTemp v3.1 maximum monthly mean(MMM) for each 3 month period. (warmest month of the 1985-2012 climatology, https://coralreefwatch.noaa.gov/product/5km/description_climatology.php ). Both the model data and the CoralTemp v3.1 data were filled where data was missing in the zonal direction using NCL’s poisson grid fill function. These data were used to calculate resilience scores for the US Virgin Islands Coral Reef Resilience Prioritization project. The US Virgin Islands (USVI) Coral Reef Resilience Prioritization project identified coral reefs and underwater habitats in the USVI that may have high resilience properties and potential to withstand current and forecasted climate change conditions, such as thermal stress, increased wave action, and coral disease outbreaks.
