The diagram to the left outlines the laboratory techniques and software sequence of operation in a generalized flow diagram for those procedures presently used in the sedimentation laboratory at the Woods Hole Coastal and Marine Science Center (WHCMSC). Because the sediment size data eventually become part of a database and as it is necessary to archive the raw unprocessed data, there must be some

Request for Analysis Form
Request for Analysis Form

formal system of recording sample identifiers. Appropriate identifiers include: requestor, cruise identification (id), project id, work requested, purpose of investigation, sample id, latitude, longitude, water depth, top-depth, bottom-depth, sample device, sampling area, and what other analyses have been completed on each sample. To this end, the use of standardized "Request for Analysis" and "Sample Identification" forms are strongly recommended as organizational aids. These completed forms should be included when samples are submitted for analysis. At this time a unique lab number should be assigned to each sample.
At the sedimentation laboratory at the Woods Hole Coastal and Marine Science Center, this number consists of two letters followed by three numbers (for example, AA795). These identifiers are manually entered into a computer using the program GSANV.

Modifications since 2005

The “Request of Analysis” and “Sample Identification” forms are provided as Microsoft Word and Microsoft Excel files, respectively. The completed forms allow sediment laboratory personnel to keep records and track analyses digitally. Information from the Sample Identification form is also imported directly into a spreadsheet (GRAINSIZE.XLS) that is the input file for the processing program GSSTAT (see software documentation for GSSTAT).
