Temperature, salinity, sigma-theta, and delta profiles were collected from CTD casts in Resurrection Bay near Seward, Alaska. Data were gathered by the R/V Little Dipper vessel as part of the Gulf of Alaska (GAK) time series. Observations span from 1970 to 1997.
Use Cases
- Analyze temperature and salinity profiles to study seasonal stratification patterns in Resurrection Bay.
- Calculate sigma-theta values to assess water density variations over the 27-year time series.
- Use delta measurements to investigate water column stability and mixing processes.
- Correlate temperature and salinity time-series data with regional climate indices.
Strengths
- 27-year temporal coverage from 1970 to 1997.
- Includes multiple physical oceanographic parameters: temperature, salinity, sigma-theta, and delta.
Limitations
- Geographic scope is limited to a single location: the mouth of Resurrection Bay, Alaska.
- Data collection ended in 1997, making the series temporally stale for contemporary analysis.
