Science Datasets

The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Map 02: ArcGIS layer showing contours of the mean of October water levels during the 2000—2009 water years (feet)

Statistical analyses and maps representing mean, high, and low water-level conditions in the surface water and groundwater of Miami-Dade County were made by the U.S. Geological Survey, in cooperation with the Miami-Dade County Department of Regulatory and Economic Resources, to help inform decisions necessary for urban planning and development. Sixteen maps were created that show contours

Topographic measurements of Little Holland Tract, Sacramento-San Joaquin Delta, California, 2015, using backpack GPS

Topographic data were collected by the U.S. Geological Survey (USGS) in 2015 for Little Holland Tract in the Sacramento-San Joaquin River Delta, California. The data were collected on foot using a global positioning system (GPS) backpack platform that consisted of survey-grade Trimble R10 and R7 global navigation satellite system (GNSS) receivers with Zephyr 2 antennas. Orthometric

Data points collected during the bathymetric survey of Lago Caonillas, Utuado, Puerto Rico, September-November 2012

This dataset contains the data points collected during the bathymetric survey of Lago Caonillas between September and November 2012 by U.S. Geological Survey. The 2012 bathymetric survey was conducted using a bathymetric/land survey system, consisting of a global positioning system (GPS) coupled to a digital depth sounder. A total of 155 survey navigation lines were established at 50 mete

Magnetotelluric data, Southern San Luis Valley, Colorado, 2006: Station 10

This dataset includes the magnetotelluric (MT) sounding data collected in 2006 in the Southern San Luis Valley, Colorado. The U.S. Geological Survey conducted a series of multidisciplinary studies, including MT surveys, in the San Luis Valley to improve understanding of the hydrogeology of the Santa Fe Group and the nature of the sedimentary deposits comprising the principal groundwater

MODFLOW-NWT groundwater flow model used to evaluate conditions in the Northern High Plains Aquifer in Colorado, Kansas, Nebraska, South Dakota, and Wyoming: U.S. Geological Survey data release

A three-dimensional groundwater flow model was developed to characterize groundwater resources and the
interaction of groundwater with streams and other hydrologic features in the Northern High Plains aquifer.
The Northern High Plains aquifer is generally unconfined; most of the water withdrawn from the aquifer is
used for irrigation. A modified version of a previously...

Spatial distribution of Rhodamine WT dye concentration measured in the Des Plaines River and the Chicago Sanitary and Ship Canal, Chicago, IL in November 2011

These data were collected during a dye tracing study of the lower Des Plaines River and lower Chicago Sanitary and Ship Canal (CSSC) in November 2011 by the U.S. Geological Survey. The study attempted to identify potential inflows of Des Plaines River water through the fractured bedrock that separates the two water bodies. Data include Rhodamine WT dye concentrations measured every 3 or 10 mi...

Survey of velocity at cross sections in the Des Plaines River near Brandon Road Lock and Dam, Joliet, Illinois (October 20, 2015)

These data were collected using a 1200 kHz TRDI Rio Grande acoustic Doppler current profiler (ADCP) in mode 12 with 25 centimeter bins from a moving boat. The data were georeferenced with a Hemisphere V102 differential Global Positioning System (GPS) receiver with submeter accuracy. The data were processed in the Velocity Mapping Toolbox (Parsons and others, 2013) to obtain a mean
