Title: POINT COVERAGE SCASMPL -- Sediment sample data for S. Calif.

Abstract:

Point coverage of known sediment samples in Southern California from the USGS usSEABED database.

Supplemental_Information:

Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government.

Although this Federal Geographic Data Committee-compliant metadata file is intended to document the data set in nonproprietary form, as well as in ArcInfo format, this metadata file may include some ArcInfo-specific terminology.

1. How should this data set be cited?

6. How does the data set represent geographic features?
   1. How are geographic features stored in the data set?

      This is a Point data set. It contains the following vector data types (SDTS terminology):

      • Point (1356)

   2. 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 0.002. Longitudes are given to the nearest 0.002. Latitude and longitude values are specified in Decimal Degrees.

      The horizontal datum used is North American Datum of 1983.
      The ellipsoid used is GRS1980.
      The semi-major axis of the ellipsoid used is 6378206.4.

7. How does the data set describe geographic features?

   Entity_and_Attribute_Overview:

   LATITUDE, LONGITUDE, WATERDEPTH, SAMPLETOP, SAMPLEBASE are measured location and sample information for each point. SITENAME is a unique value for individual sites. DATASETKEY can be correlated to individual sources in SCASMPL_REF.DOC file. SITEKEY and SAMPLEKEY are linked values useful if data are used in a relational database with other files held in usSEABED (not included here). A "1" in RECORDTYPE indicates that the data is surficial; "2" indicates a down-core sample. DATATYPE indicates what type of data were used to derive values held in characterization fields (T = textural, C = geochemical, G = phi grainsize classes). GRAVEL, SAND, MUD, CLAY are characterization fields from lab-based measurements in percentage. GRAINSIZE and SORTING are characterization fields in phi calculated from the previous four fields. SEAFLOOR CL(ASS) indicates specific type of seafloor characteristics mined by dbSEABED (ex: rock, plant, wood, and others). CLASSMBRSH (CLASS MEMBERSHIP) gives the fuzzy membership of the sample to the class noted in SEAFLOORCL (possible values: 0 to 100,where 100 indicates complete membership). HBTCODE (HYDROGRAPHIC BOTTOM CODE) is based on the U.S. Navy's method of seafloor classification. ROCKMBRSHP (ROCK MEMBERSHIP) gives the fuzzy membership of the sample to the rock class (possible values: 0 to 100, where 100 indicates complete membership). WEEDMBRSHP (WEED MEMBERSHIP) gives the fuzzy membership of the sample to the weed class (possible values: 0 to 100, where 100 indicates complete membership). CARBONATE field gives lab-based values of measured carbonate. MUNSELLCOD (MUNSELL CODE) lists the noted Munsell color code. ORGANICCAR (ORGANIC CARBON) field gives lab-based values of measured organic carbon. POROSITY, P_WAVEVELO (P_WAVEVELOCITY), S_WAVEVELO (S_WAVEVELOCITY), RELAXATION (RELAXATION TIME) give lab-based values. -99 indicates no value available.

3. What similar or related data should the user be aware of?

1. How well have the observations been checked?

   Accuracy of each attribute is dependent on accuracy of lineage data.

2. How accurate are the geographic locations?

   Horizontal positional accuracy is dependent on source accuracy and may vary from 0.005km (differential GPS) from more recent source surveys to 1 to 2 km based on radar, Loran, or dead reckoning in older surveys. Users should use their own criteria to evaluate locations of these data.

3. How accurate are the heights or depths?

4. Where are the gaps in the data? What is missing?

   Data presented here represent known lab-based textural, statistical, carbonate, and organic carbon data for the defined polygon. Other data available but not presented here include estimations of various geophysical parameters from these data, plus memberships to various fuzzy sets, such textural, compositional, geophysical, and geotechnical parameters from linguistic data

5. How consistent are the relationships among the observations, including topology?

   Point features present. Each data point has a unique identifier (SiteName) with corresponding attributes attached, including latitude and longitude in decimal degrees.

Are there legal restrictions on access or use of the data?

Access_Constraints: None
