Discrete chemical and physical oceanographic data collected during a 1991 NOAA cruise across the North and South Atlantic Ocean. The dataset includes measurements of dissolved inorganic carbon, total alkalinity, pH, nutrients, temperature, and salinity, collected using CTD and bottle instruments. These data were collected by Rik Wanninkhof of NOAA's Atlantic Oceanographic and Meteorological Laboratory as part of the World Ocean Circulation Experiment's CO2 survey.
Use Cases
- Modeling ocean carbon uptake and storage based on dissolved inorganic carbon and total alkalinity measurements.
- Analyzing ocean acidification trends based on pH and carbonate system parameters.
- Studying nutrient distributions and their relationship to biological activity based on nitrate, nitrite, and silicate data.
- Calibrating and validating ocean biogeochemical models using high-quality, discrete profile data.
Strengths
- Data collection was part of the major World Ocean Circulation Experiment, contributing to a global climate research program.
- Includes multiple co-located chemical and physical variables (e.g., DIC, TA, pH, nutrients, temperature, salinity) for a holistic view of ocean conditions.
- Specifies the exact research vessel (NOAA Ship Malcolm Baldrige), cruise identifier (OACES91_1-2), and principal investigator.
Limitations
- Last updated 1991-09-02 00:00:00; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and file size are unknown, which may limit suitability assessment.
