By:                            Automated Ingest Agent

Source:  Original data were collected as part of the response to the MC252
         Deepwater Horizon oil spill event.  Data may have been provided
         by the Subsurface Monitoring Unit (SMU), BP, EPA, DFO Canada
         (Department of Fisheries and Oceans), or various labs that
         completed sample analysis.

Actions: The original data were copied into the data/0-data/ directory.

Files:
about/
This directory contains files generated by NODC with ancillary information
about the data submission.

DWH_GY_Cruise03.xml -
  Metadata record for the archived data, in Federal Geographic Data Committee
  (FGDC) Content Standard for Digital Geospatial Metadata (FGDC-STD-001-1998)
  XML format with remote sensing extensions.

GY_Cruise_03_manifest.xml -
  This file lists all the files in the Analytical Chemistry package submitted
  by the data provider to NODC along with the MD5 hash value for each file, to
  enable verification of the integrity of the files.

0074905_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 decimal degrees).  NODC may have
  corrected geographic positions that seemed to be in error when generating
  this file.  However, NODC did not change the original data files under the
  directory data/0-data/.

0074905_map.jpg -
  Sample location map for these data.

dirinfo.txt -
  A text file, which contains the ship's call sign and cruise ID of data
  collection, to facilitate NODC's online dissemination of this data set.

data/0-data/
This directory contains the data files as submitted to NOAA by various ships in
accordance with SMU Guidance.  Various levels of compliance with SMU guidance
were achieved, with increased compliance over time.

The column labeled Analyte in the analytical chemistry data file may contain
values similar to 0.1mm.  These values are typically associated with sediment
sampling, however, samples taken at the water/seafloor interface may have been
tagged as a water matrix but included sediment results as well.
The column labeled Analyte in the analytical chemistry data file may contain
one or more instances of the variable Tentatively Identified Compound.
Tentatively Identified Compound (TIC) is assigned when compounds don't meet
the complete identification requirements.  These are specific EPA requirements
that the labs use in their analysis and reporting.  Using a GC/MS, when the
library is searched for the unknown compound, can frequently give a tentative
identification to the unknown; hence the name Tentatively Identified Compound.
In some cases the TIC is identified as a class of compounds (e.g., alkane).
