CTD Temperature and Salinity Profiles from the Alpha Helix, 1998-1999

From October 1998 to May 1999, the research vessel Alpha Helix collected six CTD cast datasets measuring temperature and salinity. The data originates from two NOAA projects: DENSE WATER in the Bering Sea and GLOBEC in the Gulf of Alaska, Resurrection Bay, and Prince William Sound. The data is archived by NOAA's National Centers for Environmental Information.

Use Cases

• Analyze vertical water column structure based on temperature and salinity profiles.
• Study dense water formation and mixing processes in the Bering Sea based on the DENSE WATER project data.
• Model coastal ocean dynamics in the Gulf of Alaska based on GLOBEC program data.
• Investigate seasonal changes in oceanographic conditions from late 1998 to mid-1999.

Strengths

• Data originates from two defined research projects: DENSE WATER and GLOBEC.
• Provides temporal coverage across a seven-month period from 1998-10-02 to 1999 05-13.
• Spatial coverage includes specific regions: the Bering Sea, Gulf of Alaska, Resurrection Bay, and Prince William Sound.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 1999-05-13 00:00:00; freshness should be verified.
• Row count is unknown, which may limit suitability assessment.
