Physical profile data from CTD casts in the coastal Western U.S. and NE Pacific were collected by Oregon State University on the R/V Wecoma. The dataset supports the Global Ocean Ecosystem Dynamics program, covering profiles from April to December 2001. It includes measurements of temperature, salinity, sigma-theta, dynamic height, percent transmittance, fluorescence, and oxygen concentration.
Use Cases
- Analyze temperature and salinity profiles to model coastal water column stratification.
- Correlate fluorescence data with oxygen concentration to study phytoplankton productivity.
- Use sigma-theta and dynamic height profiles to calculate water density and geostrophic currents.
- Model ecosystem dynamics by integrating transmittance, fluorescence, and oxygen as environmental variables.
Strengths
- Includes seven distinct physical and biological profile variables per cast.
- Data collected over an 8-month period from April to December 2001.
- Supports a major international research program (GLOBEC).
Limitations
- Limited temporal coverage to a single year (2001).
- Geographic scope is restricted to the Gulf of Alaska and NE Pacific.
- Unknown row count and sample size for statistical analysis.
