What coordinate system is used to represent geographic features?
Horizontal positions are specified in geographic coordinates, that is, latitude and longitude.
Latitudes are given to the nearest 0.0001.
Longitudes are given to the nearest 0.00001.
Latitude and longitude values are specified in decimal degrees.
The horizontal datum used is North American Datum of 1983.
The ellipsoid used is GRS80.
The semi-major axis of the ellipsoid used is 6378137.00.
The flattening of the ellipsoid used is 1/298.257222101.
The dataset contains 6 columns of information. The data are from two field activities (SEAX96017 and SEAX96024) which is the first row of each section of the data. The columns of information are as follows: sample; longitude; latitude; MGS (phi); Fe (%); Hg (ppb). Any additional information with regards to these data the user will need to acquire from the associated Chapter 7 in the Larger Work citation (https://pubs.usgs.gov/of/2000/of00-304/htmldocs/chap07/index.htm)
Work to create the CSDGM metadata file performed by VeeAnn A. Cross.
The purpose of this datalayer is to disseminate a table that contains a of sample locations and mercury concentrations in samples from Long Island Sound. No CSDGM metadata originally accompanied this dataset. This metadata file was compiled based on the data itself (minimum and maximum values) as well as publication information associated with the Larger Work citation and specifically Chapter 7.
The dataset was released in the publication without a CSDGM metadata file. In order to provide a metadata file discoverable by various systems, the skeleton metadata file was generated based on information in the publication and the dataset itself. Dataset originator names are assumed based on the associated chapter authorship. Links to access the data including the DOI link were included. Added keywords section with USGS persistent identifier as theme keyword (PID). The spatial reference information is an assumption based on the header information in the file with the datum being assumed to be consistent with the other datasets included in the Larger Work citation. The distribution contact and metadata contact reflects the person who generated the CSDGM metadata file. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent. (20230626)
