This map of United States water resource subregion hydrologic units updated boundaries to include the ocean as well as the portions of the basins that cross international borders For the use of hydrologists, ecologists, and water-resource managers in the study of surface water flows in the United States, the United States Geological Survey ...
SWBD data covers the Earth's surface between 56° southern latitude and 60° northern latitude. It is distributed in ESRI shapefile format, divided into 12,229 files, each covering one 1°-by-1° tile of the Earth's surface. SWBD data is in the public domain and is made available online for free download by NASA.
Once transmitted to NCEI, data are archived and made available for use by researchers and others in public and private sectors. The data and products offer information about climate and weather, [7] coasts, oceans, [8] and geophysics. [9] NCEI Subject Matter Experts (SMEs) collaborate on national and international research projects.
In 2015, the USGS unveiled the topoView website, a new way to view their entire digitized collection of over 178,000 maps from 1884 to 2006. The site is an interactive map of the United States that allows users to search or move around the map to find the USGS collection of maps for a specific area.
There is a strong need for depth-discrete head and water quality data in water resources studies and planning. Variations in heads with depth can identify effective aquitards that can impede recharge to deep aquifers. Vertical head profiles provide important calibration points for groundwater models.

Many governments publish open data they produce or commission on official websites to be freely used, reused, or redistributed by anyone. [1] [2] These sites are often created as part of open government initiatives. Some open data sites like CKAN and DKAN are open source data portal solutions where as others like Socrata are proprietary data ...
It was in connection with intensive studies of the Gulf Stream that the Coast and Geodetic Survey ship USC&GS George S. Blake became such a pioneer in oceanography that she is one of only two U.S. ships with her name inscribed in the façade of the Oceanographic Museum (Musée Océanographique) in Monaco due to her being "the most innovative ...
