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.

Detection Limits

(Intro) (mg = µg) Elemental detection limits for NAA are variable because some elements become very radioactive–, and can be determined at very low levels while other elements do not become very radioactive or have very short half–lives (less than 10 seconds). Activation analysis determines the total mass of an element in a sample.

Depth to Water Data in the Upper Glacial and Magothy Aquifers, April-May 2016

The depth to water table was measured at 276 groundwater monitoring wells (observation and supply) screened in the upper glacial and Magothy aquifers during April and May of 2016. This shapefile consists of the locations of those sites where water levels were measured and includes depth-to-water values which are stored in the attribute table. The shapefile was created and intended for use with...
