Ocean Temperature Profiles from Hudson Expedition 1986

1986-05-07 to 1986-08-20 temperature-depth profiles collected via expendable bathythermograph (XBT) instruments during the HUDSON cruise. Data is processed to the NODC standard C116 format, containing pairs of temperature and depth values recorded at inflection points to define the temperature curve. The dataset covers the Davis Strait, Gulf of St. Lawrence, and North Atlantic Ocean and is provided by the National Oceanic and Atmospheric Administration.

Use Cases

• Analyzing vertical temperature structure in the ocean using paired temperature-depth values.
• Studying seasonal oceanographic changes in the Davis Strait and Gulf of St. Lawrence during summer 1986.
• Calibrating or validating ocean models with historical in-situ profile data.
• Researching cruise-based observational methods and data formats like NODC C116.

Strengths

• Specific temporal coverage from May to August 1986 provides a focused seasonal snapshot.
• Data processed to a documented standard format (NODC C116) ensuring structured consistency.
• Profiles target key oceanographic regions including the North Atlantic Ocean and Davis Strait.

Limitations

• Exact row count, column names, and dataset size are unknown from all sources.
• Data freshness is unclear; the last update date (2026-03-05) on Data.gov is a future date, indicating a metadata error.
• Limited geographic coverage to a single cruise track over a three-month period.
