Historic Places: The National Register of Historic Places (Points) and National Register of Historic Places Districts (Polygons) maps show the locations of the nation’s official list of historic places worthy of preservation.

The data, provided by the U.S. Environmental Protection Agency, can be found in the Water Quality theme.

Federal Ocean Observation Buoys and Stations: The locations of buoys and monitoring stations that measure and record physical oceanographic and meteorological data. This dataset, prepared by northeastoceandata.org, compiles monitoring stations from several different sources/programs, which are shown in the map legend.
