This CDROM contains the final quality-controlled data collected
during the NEGOM Program in the Northeastern Gulf of Mexico between
November 1997 and August 2000. 

There were nine cruises, all aboard the R/V Gyre. The
same 11 cross-shelf lines were occupied during each cruise.

N1: R/V GYRE CRUISE (97G14) 16-26 November 1997
N2: R/V GYRE CRUISE (98G05) 04-15 May 1998
N3: R/V GYRE CRUISE (98G10) 25-July to 09 August 1998
N4: R/V GYRE CRUISE (98G15) 12-25 November 1998
N5: R/V GYRE CRUISE (99G07) 15-28 May 1999
N6: R/V GYRE CRUISE (99G08) 15-28 August 1999
N7: R/V GYRE CRUISE (99G12) 12-23 November 1999
N8: R/V GYRE CRUISE (00G04) 14-26 April 2000
N9: R/V GYRE CRUISE (00G08) 28-July to 08-August 2000

On each cruise, profiles of temperature, salinity, dissolved
oxygen, fluorescence, backscatterance, PAR, and percent
transmission were made with a Seabird CTD. Water samples were
taken and analyzed for salinity, dissolved oxygen, nutrients,
pigments, particulate material, particulate organic carbon and
particulate organic nitrogen. Many XBT probes were released. An
underway flow-through system measured near-surface temperature,
salinity, and fluorescence. Acoustic Doppler current profilers
measured vertical profiles of currents while underway. 

All data files are ASCII text files with UNIX line terminators.
If you view these file on a Macintosh or PC/WIN computer you may
need to convert the line endings to conform with conventions on
your platform. Some word and text processors handle foreign
line terminators transparently while most simple text processors
do not.  

Bad or missing values are flagged with -9.0, -99.0, etc.

Reports are in Adobe Portable Document Format (PDF). PDF readers
for most platforms (Macintosh, UNIX, PC/WINDOWS) are available
from www.adobe.com.

No formal final data report was produced for this project.

The Project was sponsored by the U.S. Minerals Management Service.

Here is a brief description of the contents of the various directories.

ADCP   : Acoustic Doppler current meter profiler data. Underway ADCP data
         from various systems including narrow band and broadband 150Khz
         and 38Khz systems.
 
BOTTLE : Pigments, nutrients, salinity, dissolved oxygen, particulate
         organic carbon and  particulate organic nitrogen taken from
         Niskin bottles mounted on the CTD rosette.

CTD    : Temperature, salinity, percent transmission, PAR irradiance, 
         relative fluorescence, relative backscatterance, and continuous
         dissolved oxygen profiles from lowered CTD.

         and a collection of notes taken during the cruise by onboard
         members of the science party. 

MAPS   : Post-cruise basemap plots in Adobe PDF format showing stations
         station locations for each cruise.
