The grayscale Puerto Rico and U.S. Virgin Islands shaded relief data were derived from National Elevation Dataset (NED) data, and show the terrain of Puerto Rico and U.S. Virgin Islands at a resolution of 200 meters. The NED is a raster product assembled by the U.S. Geological Survey, designed to provide national elevation data in a seamless form with a consistent datum, elevation unit, and projection. Data corrections made in the NED assembly process minimize artifacts, permit edge matching, and fill sliver areas of missing data.

The Topographic and Bathymetric Shaded Relief of North America map layer shows depth and elevation ranges using colors, with relief enhanced by shading. The image was derived from two pre-existing map layers; the Bathymetric Shaded Relief of North America, derived from ETOPO2 data, and the Color North America Shaded Relief, derived from GTOPO30 data.

This dataset is an extract from the GlobCover 2009 land cover map, covering Central and South America. The GlobCover 2009 land cover map is derived by an automatic and regionally-tuned classification of a time series of global MERIS (MEdium Resolution Imaging Spectrometer) FR mosaics for the year 2009. The global land cover map counts 22 land cover classes defined with the United Nations (UN) Land Cover Classification System (LCCS). For more information on the GlobCover project, see http://ionia1.esrin.esa.int/ Note on display: class 210: Water Bodies is set to "transparent" to improve display in the Data Basin map. Within the extract's extent, no data were removed from the original dataset.

Cruise ship ports in the Caribbean and intensity of visitation. This dataset was created on 24th April 2003 and represents all cruise ports in the Wider Caribbean and the number of calls by cruise ships that are scheduled between 1st May 2003 and 1st may 2004. Cruise ships alter their ports of call from year to year and there are other destinations that have not been included in this dataset, as no ships are scheduled.

This dataset represents the name and location of dive centres in the Caribbean as points.

This inventory was originally created by Harp and others (2016) describing the landslides triggered by the M 7.0 Haiti earthquake that occurred on 12 January 2010 at 21:53:10 UTC. Care should be taken when comparing with other inventories because different authors use different mapping techniques. This inventory also could be associated with other earthquakes such as aftershocks or triggered events. Please check the author methods summary and the original data source for more information on these details and to confirm the viability of this inventory for your specific use. With the exception of the data from USGS sources, the inventory data and associated metadata were not acquired by the U.S. Geological Survey...

Fish collections made at Buck Island Reef National Monument with the ichthyocide rotenone in 2001 at 58 stations followed by 10 days each in April 2011 and January 2012 surveying poorly sampled shoreline habitats with rotenone and clove oil and inland streams with seine.

The Bathymetry of North America map layer shows depth ranges using colors. The image was derived from the National Geophysical Data Center’s ETOPO2 elevation data, which is an elevation database gridded at 2-minute resolution, containing elevation and bathymetry for the world. The image was produced from the October 2001 data set.

HUC-14 Watershedsd for the Island of St. John. Because of the size of the USVI, most planning is done at HUC-14 level.

This data set represents the extent, approximate location and type of wetlands and deepwater habitats in the United States and its Territories. These data delineate the areal extent of wetlands and surface waters as defined by Cowardin et al. (1979). Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and near shore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their...

In the 1980s, The Puerto RIcan legislature designated a "greenbelt of agricultural lands to create a buffer zone around the El Yunque Forest." The purpose of the buffer zone was to provide a transitional area from the Forest to the land outside, so that urbanization and its impacts would not encroach upon the Forest. Since then, the buffer zone has decreased in size as development increased. The decrease in the buffer zone is due to government zoning exceptions, the result of pressure from developers, and some illegal development. A USDA Forest Service report indicates that El Yunque Forest ecosystem is increasingly at risk as urbanization in the buffer zone increases. El Yunque's ability to support wildlife will...
