Coastal CTD Profiles for Pollutant Transport Study 1979-1981

Temperature, salinity, pressure, and transmissivity profile data originate from two research cruises aboard the R/V Thomas G. Thompson off northern Oregon and southern Washington. The National Oceanic and Atmospheric Administration collected this data as part of a Department of Energy program investigating pollutant transport and sediment dispersal. This multidisciplinary study focused on coastal upwelling dynamics and phytoplankton productivity distribution.

Use Cases

• Analyzing coastal upwelling dynamics using temperature and salinity profiles.
• Studying the influence of submarine canyons on along-isobath currents with pressure and transmissivity data.
• Quantifying phytoplankton productivity distribution through transmissivity measurements related to water clarity.
• Modeling pollutant and sediment transport in the Washington-Oregon coastal zone using hydrographic cast data.
• Investigating multidisciplinary oceanographic processes on a continental shelf.

Strengths

• Data was collected as part of a structured, multidisciplinary Department of Energy-sponsored research program.
• Profiles include four key oceanographic parameters: temperature, salinity, pressure, and transmissivity.
• The dataset's cross-platform presence on Data.gov and NASA EarthData indicates its established use and importance.

Limitations

• Specific row counts, file sizes, and a complete column list are unavailable from all sources.
• There is a significant conflict in the 'last updated' metadata, with dates reported as 1981-09-03 and 2026-03 06.
• License and author information is not provided by any source.
