Gulf of Maine data contains over 500,000 temperature-salinity profiles binned at 10-meter depth intervals from 0 to 300 meters. The dataset was compiled by NOAA NCEI from the Canadian Fisheries and Oceans Hydrographic database. It covers observations from 1912 to 1930.
Use Cases
- Analyze temporal trends in water salinity and temperature at specific depth intervals over an 18-year period.
- Calculate sigma t (density) from salinity and temperature measurements to study water column stability.
- Model historical oceanographic conditions in the Gulf of Maine using profiles from hydrographic bottles and CTD casts.
- Validate regional climate models by comparing simulated data against observed temperature-salinity profiles from 1912-1930.
Strengths
- Over 500,000 temperature-salinity profiles provide substantial observational density.
- 18-year temporal coverage (1912-1930) allows for analysis of decadal-scale variability.
- Data is binned at consistent 10-meter depth intervals from 0 to 300 meters.
Limitations
- Data is temporally stale, with the last update recorded in 1930.
- Specific row count, column names, and sample size for the Gulf of Maine subset are unknown.
- Geographic scope is limited to the Gulf of Maine, a sub-region of the broader Northwest Atlantic database.
