2006 Hypoxia Watch Bottom CTD Station Locations
|
The NOAA Hypoxia Watch project provides near-real-time, web-based maps
of dissolved oxygen near the sea floor over the Texas-Louisiana continental shelf
during a
period that extends from mid-June to mid-July. 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.

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. A new attribute
was added to reflect the cruise leg number. The data was then exported individually
to tab-delimited text files. After quality control checks, any corrections were made
to the edited files. These individual files were combined into one complete text
file for the whole season. This text file was then imported into ESRI's ArcMap and
exported to a shapefile. Attribute fields were 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 master map shapefile, 10 meter Depth Contour, and
200 meter Depth Contour shapefiles.

NOAA created the National Centers for Environmental Information (NCEI) by merging
NOAA's National Climatic Data Center (NCDC), National Geophysical Data Center (NGDC),
and National Oceanographic Data Center (NODC), including the National Coastal Data
Development Center (NCDDC), per the Consolidated and Further Continuing Appropriations
Act, 2015, Public Law 113-235. NCEI launched publicly on April 22, 2015.
