Description
From May 15 to June 26, 1993, chemical and physical oceanographic data were collected from the R/V Thomas G. Thompson in the coastal waters of Southeast Alaska, the Gulf of Alaska, and the North Pacific Ocean. The data include measurements of carbon dioxide partial pressure, dissolved inorganic carbon, alkalinity, temperature, salinity, nutrients, and tracers like CFCs and isotopes. These data were collected by Catherine Goyet of the University of Perpignan via Domitia as part of the World Ocean Circulation Experiment (WOCE) Hydrographic Program.
Use Cases
Modeling ocean carbon uptake based on partial pressure of carbon dioxide and dissolved inorganic carbon measurements.
Studying water mass circulation and mixing using chlorofluorocarbon (CFC-11, CFC-12) and tritium tracer data.
Analyzing nutrient dynamics in coastal ecosystems based on nitrate, phosphate, and silicate profiles.
Calibrating satellite-derived sea surface temperature and salinity products with in-situ bottle and CTD data.
Strengths
Data collection is part of the major World Ocean Circulation Experiment (WOCE) program, a benchmark for ocean climate research.
Includes a wide array of 22 measured variables relevant to carbon cycle and ocean physics.
Covers a specific cruise track and time period (1993-05-15 to 1993-06-26) with precise temporal bounds.
Limitations
