In 2008, there was a fall Hypoxia Watch Cruise in October and November. The NOAA National Marine Fisheries Service Mississippi Laboratories at Pascagoula and Stennis Space Center and the NOAA National Centers for Environmental Information (NCEI) at Stennis Space Center began the Hypoxia Watch project in 2001. Scientists aboard the NOAA Research Vessel Oregon II measure seawater properties, such as water temperature, salinity, chlorophyll, and dissolved oxygen at each of approximately 240 locations as the Oregon II makes its way from Brownsville, Texas, to the mouth of the Mississippi River, then into Florida waters. A scientist aboard the ship processes the measurements from electronic dissolved oxygen sensors, checks the measurements periodically with chemical analyses of the seawater, then sends the data by e-mail to NCEI at Stennis Space Center approximately every three to five days. Personnel at NCEI transform the dissolved oxygen measurements into contour maps, which identify areas of low oxygen, or hypoxia. During the 6-week cruise, as the data is received from the ship, NCEI generates new maps and immediately publishes them on the web. The first map will usually cover an area near Brownsville, TX, then gradually areas along the Texas, Louisiana, and Florida coasts will be added. Maps are published every three to five days from approximately June 10 to July 20. These maps form the basis for summertime advisories on anoxic and hypoxic conditions in the North-central Gulf of America (formerly Gulf of Mexico) and are intended for federal, state, and local government environmental decision makers. Other uses include recreational and commercial fishing, educators, resource managers, and researchers. Scientists use this environmental data to understand the effects of the physical environment on fish and other marine organisms. The dissolved oxygen maps generated during the SEAMAP cruise also help NOAA scientists plan the annual survey of the Gulf of America hypoxic zone, which is conducted by the Louisiana Universities Marine Consortium (LUMCON) in late July, when the hypoxic zone is typically at its peak. Cooling waters and storms in the Fall mix up the water throughout the Gulf and restore normal oxygen levels to the sea floor.

Latitude and longitude values were converted to decimal degrees. The text file was then imported into Surfer (Golden Software Inc.), gridded using the Kriging technique, and saved to a grid file. The grid was contoured using intervals defined from 0 mg/l (milligram/liter) to 8.0 mg/l in 0.5 mg/l intervals. The grid was brought into ESRI's ArcView version 3.2 and turned into a shapefile. The shapefile was cleaned using an Avenue script to separate each polygon which was then clipped to the boundary of the CTD (conductivity temperature depth) station locations. Attribute fields were added to the shapefile's table and then queried to match polygons to their range of oxygen values. A basemap of the Gulf of Mexico was created in ESRI's ArcMap using the Gulf of Mexico master map shapefile, 10 meter Depth Contour, and 200 meter Depth Contour shapefiles. Two maps were created using the basemap, one with the station locations point shapefile and another with the dissolved oxygen contours. The contour's color scheme was a red-green spectrum with red for the low oxygen areas and green for the high oxygen areas.

The grid was contoured using intervals defined from 0 mg/l (milligram/liter) to 8.0 mg/l in 0.5 mg/l intervals.

Two geoprocessing tools were developed at NCEI to automate some of the hypoxia related data processing. The Data Preparation tool was used to create a shapefile of the CTD stations from the raw text files.

The grid was contoured using intervals defined from 0 mg/l (milligram/liter) to 8.0 mg/l in 0.5 mg/l intervals. The Final Processing tool created a TIN using the CTD station shapefile and derived a clip graphic from the extent of the CTD stations. This graphic was used to clip the contour shapefile.
