Fisheries-Oceanography Investigations: CTD Profiles from the North Pacific

NOAA Ship Miller Freeman collected 54 days of continuous oceanographic data during the 1997 Fisheries-Oceanography Cooperative Investigations (FOCI). The dataset contains vertical profiles of water temperature, salinity, Photosynthetic Active Radiation (PAR), and sigma-theta from the north Pacific Ocean. These measurements provide a snapshot of ocean conditions relevant to fisheries research.

Use Cases

• Analyzing water column stratification based on sigma-theta and temperature profiles.
• Studying light penetration for phytoplankton using Photosynthetic Active Radiation (PAR) data.
• Investigating oceanographic conditions for fisheries habitats from CTD cast profiles.
• Calibrating regional ocean models with historical temperature and salinity data.

Strengths

• Contains a continuous 54-day time series of oceanographic measurements from a specific research cruise.
• Data includes multiple co-located physical and chemical parameters (temperature, salinity, PAR, sigma-theta).
• Collected as part of a coordinated, named scientific program (Fisheries-Oceanography Cooperative Investigations).

Limitations

• Column names and specific data structure are not documented in the provided metadata.
• Conflicting last updated dates exist between sources (1997-04-13 and 2026-03-05).
• Key metadata such as row count, file size, and license information is missing from all sources.
