WODselect COMMA SEPARATED VALUE ("csv") FORMAT DESCRIPTION

For technical help or to report problems, please e-mail OCL.help@noaa.gov
 
GENERAL:

The "WODselect csv format" is a space and comma-separated values format. Each value field is separated by commas, for easy computer access of the data,
with space separation to also make the file readable with the human eye.

Each oceanographic cast starts with the keyword CAST in the first column, and is split into the following general content sections which are marked
with the following text labels in the first column field:

Biological code information can be read from the WOD09 code list.

GENERAL FIELDS:
 
Starting Indicator Ending Indicator Content
CAST next section start Station position, date, and cruise identification
METADATA next section start Country, NODC accession#, ship/platform, project, institution, meteorology, and other measurement related information
VARIABLES END OF VARIABLES SECTION profile measurements (if present)
BIOLOGY METADATA BIOLOGY plankton sampling information (if present)
BIOLOGY END OF BIOLOGY SECTION plankton measurements (if present)
