Texas-Louisiana Shelf Circulation Study: Hydrographic and Meteorological Data 1992-1994

Texas A&M University collected physical oceanographic and meteorological data from the R/V Gyre in the Texas-Louisiana shelf region from April 1992 to October 1994. The dataset includes measurements from current meters, CTD casts, and meteorological sensors as part of the LATEX Part A study. It documents parameters like water velocity, temperature, salinity, conductivity, and atmospheric conditions to study shelf circulation and transport processes.

Use Cases

• Analyzing shelf current patterns using East/West (U) and North/South velocity components.
• Studying water column structure through CTD parameters like pressure, temperature, salinity, and sigma-theta.
• Investigating air-sea interactions using meteorological sensor data for air pressure, temperature, wind speed, and direction.
• Examining biological and optical properties via CTD measurements of fluorescence, irradiance (PAR), and transmission.

Strengths

• Data collection spans a 2.5-year period from 09 April 1992 to 02 October 1994, providing a substantial temporal record.
• Measurements integrate multiple instrument types (current meters, CTDs, meteorological sensors) for a multi-faceted view of the environment.
• Dataset is hosted on multiple authoritative platforms (Data.gov, NASA EarthData), indicating recognized importance and curation.

Limitations

• Critical metadata conflicts exist: the last updated date is reported as 2026-04-01 on Data.gov and 1994-10-02 on NASA EarthData.
• Essential structural information like row count, column names, and file size is unavailable across all sources.
• Bottle cast data, mentioned as part of the study, is explicitly noted as not included in this accession.
