From November 15 to November 22, 2018, surface water samples were collected during the R/V Selfoss Transit 846 cruise in the North Atlantic Ocean. The dataset contains discrete measurements of dissolved inorganic carbon, total alkalinity, pH on the total scale, and nutrients. These data were analyzed by NOAA's Atlantic Oceanographic & Meteorological Laboratory and the Marine and Freshwater Research Institute in Iceland to monitor ocean acidification trends.
Use Cases
- Monitoring short-term ocean acidification trends based on pH and dissolved inorganic carbon measurements.
- Analyzing surface water carbon chemistry based on total alkalinity and pH on the total scale.
- Studying nutrient concentrations and their relationship with ocean acidification parameters.
- Calibrating or validating ocean acidification models based on discrete surface measurements.
Strengths
- Data is associated with a specific research cruise (R/V Selfoss Transit 846) with a known time range (2018-11-15 to 2018-11-22).
- Measurements are analyzed by two specific institutions: NOAA's AOML and Iceland's Marine and Freshwater Research Institute.
- Data collection supports the objectives of the NOAA Ocean Acidification Program's Ships of Opportunity Program.
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 bias inherent to a single transit cruise in the North Atlantic.
