Discrete profile measurements of dissolved inorganic carbon, total alkalinity, other hydro

Discrete profile measurements of dissolved inorganic carbon, total alkalinity, and other chemical parameters were collected during the R/V G.O. Sars cruise in the Greenland and Iceland Seas from August 2 to 12, 2016. The dataset, part of the GO-SHIP Section 75N repeat hydrography program, includes temperature, salinity, oxygen, nutrients, and chlorofluorocarbon data. It is provided by the National Oceanic and Atmospheric Administration.

Use Cases

• Modeling ocean acidification impacts based on dissolved inorganic carbon and total alkalinity measurements
• Analyzing water mass circulation and ventilation based on chlorofluorocarbon (CFC-11, CFC-12) tracers
• Studying biogeochemical nutrient cycles based on nitrate, nitrite, and phosphate data
• Calibrating and validating satellite-derived or model-based salinity and temperature fields based on discrete CTD profiles

Strengths

• Includes multiple co-located chemical and physical parameters (carbon, nutrients, CFCs, temperature, salinity) for integrated analysis
• Data is from a dedicated repeat hydrography cruise (GO-SHIP) following standardized protocols
• Covers a specific 10-day period in August 2016, providing a temporal snapshot

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic and seasonal bias inherent to a single cruise in the summer
