Marine Temperature and Salinity Profiles from 1991-1992

N9201 CTD and XBT Data contains marine observation data for water temperature and salinity. The dataset was collected by the organization SCIOPS from December 1991 to February 1992. Measurements include temperature profiles to 500m depth via XBT and temperature and salinity profiles to 1000m depth via CTD.

Use Cases

• Analyze vertical temperature distribution up to 1000m depth from CTD data.
• Model the relationship between water depth and temperature using XBT-derived depth calculations.
• Study seasonal water column structure in the observation period using temperature and salt content profiles.
• Validate oceanographic models with in-situ temperature and salinity measurements from the early 1990s.

Strengths

• Temperature measurements span two distinct depth ranges: up to 500m (XBT) and 1000m (CTD).
• Data collection covers a defined 3-month period from December 1991 to February 1992.

Limitations

• Dataset is temporally limited to a single season from over 30 years ago.
• Specific geographic location, row count, and sample resolution are unknown.
• Data is classified by depth in meters, but the original sampling interval is unspecified.
