Gulf of Mexico Hydrographic and Chemical Measurements from 2004-2009

NOAA NCEI Accession 0088164 contains physical and chemical oceanographic data collected via bottle samples and CTD casts in the Gulf of Mexico. Measurements were taken from the R/V Gyre and R/V Pelican between April 2004 and July 2009. The data were submitted for the 'Mechanisms Controlling Hypoxia on the Louisiana Shelf' project to support modeling of regional hypoxia.

Use Cases

• Modeling dissolved oxygen levels (hypoxia) using temperature, salinity, and nutrient concentration data from CTD profiles.
• Analyzing seasonal and interannual variability in water column stratification from conductivity-temperature-depth (CTD) time-series.
• Correlating bottle sample chemical measurements (e.g., nitrate, phosphate) with physical CTD data to study biogeochemical processes.
• Calibrating hydrodynamic-biological-geochemical models with in-situ observational data from interdisciplinary process cruises.

Strengths

• Data collected over a 5-year period from April 2004 to July 2009.
• Includes interdisciplinary measurements from process cruises and shelf-wide surveys.
• Supports a specific modeling initiative for hypoxia on the Louisiana Shelf.

Limitations

• Specific row count, column names, and sample size are unknown.
• Data is temporally stale, with the last update in July 2009.
• Geographic scope is limited to the Texas-Louisiana Shelf region of the Gulf of Mexico.
