NOAA ESRI Grid - predictions of seabird diversity in the New York offshore planning area made by the NOAA Biogeography Branch

This raster was derived from multiple individual species season models. The model also includes spatially-explicit uncertainty estimates represented in another raster dataset.

Raster values represent the annual predicted seabird Shannon diversity index. The Shannon index incorporates both presence and relative abundance. Species and groups that were not modeled in any season did not contribute to index calculation.
