Nonindigenous Aquatic Species (NAS) Database Non-freshwater Specimens
Listed in NASA Earthdata CMR
This dataset contains the non-freshwater specimens from the Nonindigenous Aquatic Species (NAS) database, which was established as a central repository for spatially referenced biogeographic accounts of introduced aquatic species.
Description
The NAS program provides scientific reports, online/real-time queries, spatial data sets, regional contact lists, and general information. The data is made available for use by biologists, interagency groups, and the general public.
The geographical coverage is the United States. The accuracy of the dates in the dataset can be accurate, an estimated date, or based on the publication year. This date is not necessarily the first introduction in that location.
