CTD Oceanographic Profiles from the Gulf of Alaska, 1999

The Gulf of Alaska is the primary region for this dataset of 188 CTD casts measuring pressure, temperature, and salinity. NOAA Ship Rainier collected 185 of the casts between August and October 1999, with three additional casts from Florida lakes. Ruby Becker of NOAA's National Ocean Service submitted the data, which was collected using a Sea-Bird SBE 19 SEACAT profiler.

Use Cases

• Analyze vertical ocean structure based on pressure, temperature, and salinity profiles.
• Study seasonal changes in Gulf of Alaska water masses based on data collected over several months.
• Validate or calibrate regional oceanographic models based on in-situ CTD measurements.
• Investigate instrument performance and data consistency based on measurements from a Sea-Bird SBE 19 profiler.

Strengths

• Contains 188 individual CTD casts, providing multiple sampling points.
• Specifies the instrument used: a Sea-Bird SBE 19 SEACAT profiler.
• Provides clear geographic focus for 185 casts in the Gulf of Alaska.

Limitations

• Last updated 1999-12-15 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
