Gulf of Alaska hydrophysical and hydrochemical data were collected from CTD casts aboard the R/V Alpha Helix. The dataset includes profiles of temperature, salinity, sigma-theta, deltas, oxygen concentration, and fluorescence. Data were gathered by NOAA_NCEI as part of the GLOBEC project from October 1997 to May 1998.
Use Cases
- Analyzing temperature and salinity profiles to study water column stratification.
- Correlating oxygen concentration with fluorescence data to assess phytoplankton productivity.
- Examining sigma-theta profiles to understand seawater density variations.
- Tracking changes in deltas and other hydrochemical parameters over the 1997-1998 period.
Strengths
- Data collected from a dedicated research vessel (R/V Alpha Helix) for a specific project.
- Includes multiple concurrent oceanographic parameters (temperature, salinity, oxygen, fluorescence).
- Time range covers a 7-month period from October 1997 to May 1998.
Limitations
- Dataset size, row count, and file formats are unknown.
- Data is from a single vessel in the Gulf of Alaska, limiting spatial coverage.
- Data collection ended in May 1998, making it temporally stale for contemporary analysis.
