Description:
Abstract:
Point coverage of known sediment samplings, inspections and probings from the USGS usSEABED, Sydney University and Colorado University goSEABED, and Colorado University goSEABED data collections. Integrated using the software system dbSEABED.
Purpose:
These data are intended to assist research, education, policy development
commerce, and the general public. The data can be used with geographic
information systems (GIS) and relational database (RDB) software
to display geologic, environmental and oceanographic information.
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,
this metadata file may include some vendor-specific terminology.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report: Accuracy of each attribute is dependent on accuracy of lineage data.
Logical_Consistency_Report:
Point features present.
Each data point has a unique identification (SiteName, Dataset, Date,
Latitude, Longitude, Water Depth, Subbottom Depth, Described Phase)
with corresponding attributes attached.
Completeness_Report:
The data represent measured, described and calculated
field- and lab-derived values of textural, compositional, geological
and geophysical parameters.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
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 or more based on radar, Loran, or dead reckoning in older
surveys. Users should use their own criteria to evaluate locations of
these data. The precision of the output positions is 0.00001 degrees
(approx 1m).
