CLIVAR_AR07E_2005: Discrete Hydrographic Profiles from the North Atlantic Ocean

Discrete profile measurements of dissolved inorganic carbon, total alkalinity, temperature, salinity, dissolved oxygen, and nutrients were collected during the R/V Pelagia cruise CLIVAR_AR07E_2005 in the North Atlantic Ocean from 2005-09-07 to 2005-10-05. The data are part of the International CLIVAR Global Ocean Carbon and Repeat Hydrography Program, which systematically re-occupies select WOCE/JGOFS sections to quantify changes in heat, freshwater, and carbon dioxide storage and transport. The dataset is provided by the National Oceanic and Atmospheric Administration.

Use Cases

• Quantifying changes in ocean carbon storage based on dissolved inorganic carbon and total alkalinity measurements.
• Analyzing ocean acidification trends using the profile data for carbonate system parameters.
• Studying water mass properties and circulation in the North Atlantic based on temperature, salinity, and oxygen profiles.
• Modeling nutrient cycles and primary productivity using nitrate, nitrite, phosphate, and silicate data.

Strengths

• Data collection occurred over a defined 29-day cruise from 2005-09-07 to 2005-10-05.
• Profile measurements include multiple key oceanographic variables: dissolved inorganic carbon, total alkalinity, temperature, salinity, dissolved oxygen, and nutrients.
• Dataset is part of the systematic International CLIVAR Global Ocean Carbon and Repeat Hydrography Program.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Data may reflect geographic and temporal bias inherent to a single cruise in the North Atlantic Ocean in 2005.
