The NOAA National Marine Fisheries Service Mississippi Laboratories at Pascagoula and Stennis Space Center and the NOAA's National Centers for Environmental Information (NCEI) 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, as the Oregon II cruises the waters south of Pascagoula, MS and then makes its way from Brownsville, Texas, to the mouth of the Mississippi River. 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 FTP to the NCEI approximately every three to four days. Physical Scientists at NCEI transform the dissolved oxygen measurements into contour maps, which identify areas of low oxygen, or hypoxia. During the cruise, as the data is received from the ship, NCEI generates new maps and publishes them on the web. The first map will usually cover an area off the Mississippi coast, successive maps will add areas of the continental shelf from Brownsville to Corpus Christi, and the final map will usually cover the entire Texas-Louisiana-Mississippi coast. Maps are published every three to four days from approximately June 22 to July 20. This environmental data complements the main objective of the SEAMAP cruise, which is to survey stocks of commercially important fish in the Gulf of Mexico. The Southeast Area Monitoring and Assessment Program (SEAMAP) is a cooperative State, Federal, and university program that collects, manages and disseminates fishery-independent data and information in the southeastern United States. The effort is part of the SEAMAP summer groundfish survey conducted in the Gulf of Mexico by the National Marine Fisheries Service aboard the NOAA Ship Oregon II. The survey follows a predetermined stratified random survey design to sample fishes and invertebrates in trawls, bongo and neuston nets, and acquire environmental data with conductivity-temperature-depth (CTD) hydrocasts at stations located in the general area between the 10 and 200 m isobaths from Brownsville, Texas eastward to the Mississippi River. The CTD is equipped with sensors to measure water temperature, salinity, dissolved oxygen, fluorescence, and transmittance continuously from the surface to the sea bottom. The cruise is divided into up to three legs of varying lengths and sampling occurs during June and July, depending on weather and equipment. The bottom oxygen maps are produced approximately weekly during the four week survey cruise. The actual CTD data from which these maps are derived is available from NOAA National Marine Fisheries Service Mississippi Laboratory in Pascagoula after the R/V Oregon II returns to port.The Hypoxia Watch process was developed by the NOAA CoastWatch Gulf of Mexico Regional Node at Stennis Space Center. completed NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact NCEI Contact Information Information for contacts at NCEI. information pointOfContact asNeeded https://www.ncei.noaa.gov/waf/hypoxia-waf/maps/2006-hypoxia-contours.jpg JPEG Image of the 2006 Hypoxia Watch bottom dissolved oxygen contours.

The bottom oxygen maps are produced approximately weekly during the four week survey cruise. The actual CTD data from which these maps are derived is available from NOAA National Marine Fisheries Service Mississippi Laboratory in Pascagoula after the R/V Oregon II returns to port.The Hypoxia Watch process was developed by the NOAA CoastWatch Gulf of Mexico Regional Node at Stennis Space Center. CoastWatch provides satellite imagery and other environmental data to government decision makers and academic researchers. The Gulf of Mexico Regional Node is one of several sites throughout the United States set up for the processing and distribution of CoastWatch information. One area of current research is to see if imagery taken from satellites and aircraft can be useful in analyzing and predicting hypoxic conditions. Although remotely sensed imagery cannot directly measure dissolved oxygen levels in the ocean, it can measure other things that contribute to the formation of hypoxic waters, such as Sea Surface Temperature and chlorophyll. NASA sent an oceanographer on the 2002 summer SEAMAP cruise to test the application of remote sensing to the Gulf of Mexico hypoxia problem. true Feature Catalogue for Gulf of Mexico Hypoxia Watch Bottom Dissolved Oxygen Contours for June and July SEAMAP Cruise of 2006 publication NOAA National Centers for Environmental Information https://www.ncei.noaa.gov/waf/hypoxia-waf/documents/hypoxia/Feature_Catalogue/2006-Hypoxia-ContoursFC.xml originator NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact NCEI Contact Information Information for contacts at NCEI. information distributor In most cases, electronic downloads of the data are free.

The CTD cast takes 10-30 minutes, depending on the depth. The ship may drift up to 0.2 km depending on the velocity of surface currents and the depth of the cast. Vertical Positional Accuracy Dissolved oxygen measurements (sampled 24 times per second) made as the CTD is lowered are averaged into 1-meter depth bins. "Bottom" or "Depth" in this data set is the deepest 1-meter depth bin. Crewmembers attempt to get the CTD as close as possible to the sea floor without touching it. none none The manufacturer's specifications state that the SBE43 oxygen sensor deployed on the CTD (Conductivity-Temperature-Depth) is accurate to within 2% of the oxygen saturation level and drifts at a rate of about 2% for each 1,000 hours of use. The temperature, conductivity, oxygen, transmittance, fluorescence, and photosynthetically active radiation (PAR) sensors deployed on the CTD are sent to the manufacturer for calibration at least once per year. Dissolved oxygen measurements made by the sensor are compared to a Winkler titration (triplicate water samples) once daily during the cruise to verify proper operation of the sensor and to alert the data manager to any excessive sensor drift. During the course of the hypoxia cruise, the individual ASCII text files containing the data were loaded into an Excel spreadsheet, checked for errors and delimited. Latitude and longitude values were converted to decimal degrees. The data was then exported individually to tab-delimited text files. After quality control checks, any necessary corrections were made to the edited files. These individual files were combined into one season-wide text file. This text file was then imported into ESRI's ArcMap and into ESRI's Geostatistical Analyst Extension, gridded using the Kriging technique, and the resulting grid was exported to a shape 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 shapefile was cleaned manually to remove unnecessary polygons and then the file was clipped to the boundary of the CTD (conductivity temperature depth) station locations. Attribute fields may have been added, renamed, or removed from the shapefile's table, as needed. A basemap of the Gulf of Mexico was created in ESRI's ArcMap using the Gulf of Mexico coastal area, 10 meter Depth Contour, and 200 meter Depth Contour shapefiles. The contour's color scheme was a red-green spectrum with red for the low oxygen areas and green for the high oxygen areas.
