OVIDE-16: North Atlantic Ocean Carbon and Hydrographic Profiles

North Atlantic Ocean data from the 2016 OVIDE-16 research cruise includes discrete and profile measurements of total alkalinity, pH, oxygen, temperature, salinity, nutrients, and chlorofluorocarbons. The dataset supports the GO-SHIP program's goal of quantifying changes in ocean heat, freshwater, and carbon dioxide storage and transport. It was collected using instruments such as an alkalinity titrator, CTD, Niskin bottles, and a spectrophotometer.

Use Cases

• Quantifying changes in ocean carbon storage based on total alkalinity and pH measurements.
• Analyzing water mass properties and circulation using CTD-derived temperature, salinity, and oxygen profiles.
• Studying nutrient dynamics and biogeochemical cycles from discrete nutrient samples.
• Investigating ocean ventilation timescales using chlorofluorocarbon (CFC) tracers.
• Calibrating and validating oceanographic models with in-situ hydrographic and chemical data.

Strengths

• Contains data from 138 CTD stations, providing detailed vertical profiles.
• Includes 66 sediment sampling events, adding a benthic component to the hydrographic survey.
• Covers a specific, well-documented cruise (OVIDE-16) with a clear temporal range from 2016-06-17 to 2016-07-31.

Limitations

• Column names and data schema are not provided in any source, limiting immediate usability.
• Conflicting 'last updated' dates (2016-07-31 and 2026-03-06) create uncertainty about metadata freshness.
• Key metadata such as row count, file size, and specific license are listed as unknown or null across all platforms.
