Abstract: This sediment database contains data on collection, location, description, and texture of samples taken by numerous marine sampling programs. Although most records contain complete grain size analyses, some are simple bottom descriptions from rocky and bouldery locations where samples were not taken. Most of the samples were collected with some type of grab sampler; however, a few were obtained by coring.
Purpose: The purpose of this report is to describe the field methods used to collect marine sediment samples and the laboratory methods used to determine and characterize the grain-size distributions, to present these data in several flat-file formats that can be readily employed by interested parties, and to provide referenceable verified data and metadata to an Access relational database being developed as part of the USGS Coastal and Marine Geology ProgramÆs Aggregates Project.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report: Those samples from the USGS's Woods Hole Science Center labs (coded with a "3") were imported into usSEABED. Those coded with "1" and "2" represent the ConMar data and are included elsewhere. In the original report, all samples were given as individual analyses with attached database IDs (DB_IDs), with no effort made to group subsamples from the same core together. Here, these samples are grouped together, and downcore analyses are included under the topmost sample's DB_ID, given in brackets in the sitename. Subsample DB_IDs are included as metadata in the input data resource file. Data are listed in order of the topmost sample's DB_IDs. SEDCLASS classification are included as Shepard classification for all samples with textural analyses (input field LTH:30). For those samples without textural analyses (mostly boulders, n = 89), the SEDCLASS description are included in input field LTH:8 for parsing by the dbSEABED software.
