Water salinity, temperature, and sigma-t density data binned at 10-meter depth intervals from 300 meters to the surface. The dataset contains over 500,000 temperature-salinity profiles for the Northwest Atlantic, sourced from the Canadian Fisheries and Oceans Hydrographic database. NOAA NCEI provides this data, which covers the period from 1981 to 2005.
Use Cases
- Analyzing seasonal and interannual trends in water temperature and salinity at specific depth intervals.
- Modeling water density (sigma-t) from temperature and salinity measurements to study ocean stratification.
- Calibrating regional ocean circulation models using historical hydrographic profile data from the Gulf of Maine.
- Investigating correlations between surface (0-10m) salinity data and freshwater input or precipitation patterns.
Strengths
- Over 500,000 temperature-salinity profiles provide a substantial observational base.
- Data spans a 25-year time range from 1981 to 2005 for longitudinal analysis.
- Depth-binned data at 10-meter intervals from 0 to 300 meters offers vertical structure detail.
- Integrates data from multiple instrument sources including CTD casts and bathythermographs.
Limitations
- The dataset is temporally stale, with the last update recorded in 2005.
- Specific row count, column names, and sample size for the Gulf of Maine subset are unknown.
- Data integration from varied sources may introduce inconsistencies in measurement protocols.
