about/
This directory contains files created by NCEI staff and processing, including
'negotiable' information between NCEI staff and the data provider.

0000559_lonlat.txt -
  Contains sample locations for these data. Each row contains the
  geographical position where these data were collected (longitude in the
  left column and latitude in the right column, both in degrees). NCEI may
  have corrected geographic positions that seemed to be in error when
  generating this file. However, NCEI did not change the original data files
  under the directory data/0-data/.

Source: These data were received from Nicolaus Adams and Dr. Vera Trainer of the Marine Biotoxin
Program at the NOAA Northwest Fisheries Science Center, Seattle, WA. Email and other
documentation regarding the data transfer were not archived.

August 22, 2001: NODC created a text version of the MS Word document, SAMPCOL.DOC. The ASCII file,
SAMPCOL.txt, is in the data/1-data/ directory. NODC created the file about/nodc_fgdc.txt, which uses
the Federal Geographic Data Committee (FGDC) Content Standard for Digital Geospatial Metadata
(CSDGM) structure to describe the contents of the data files in accession 0000559.

January 2006:
During the accessioning process, NODC created four files to include as
additional metadata for this data collection. These files include a list
of all latitude-longitude pairs for observations, bounding values that
indicate the northernmost, southernmost, easternmost and westermost
boundaries of the data, and graphical plots of all data locations in a
.jpg and .ps format.

The files use the following naming conventions:

#######_lonlat.txt - this file is created by extracting the longitude
and latitude values for all station locations in the data. The list of
longitude-latitude pairs is then processed to remove duplicate stations
and to reformat the values to decimal degree formats, if necessary. The
left column contains longitude values, the right column contains latitude
values.

In accordance with FGDC guidelines, North latitude and East longitude are
positive values, South latitude and West longitude are negative values.

#######_box.txt - this file is generated by a processing script
developed at NODC that analyses the values in #######_lonlat.txt and
outputs the northernmost, southernmost, easternmost and westermost
values.

#######_map.jpg - this JPEG file is created by plotting the values in
#######_lonlat.txt using the unix plotting software Generic Mapping
Tools (GMT).

#######_map.ps - this PostScript image file is created by plotting the values in
#######_lonlat.txt using the unix plotting software Generic Mapping
Tools (GMT).
