Discrete measurements of dissolved inorganic carbon, alkalinity, and nutrients were collected aboard the R/V Maria S. Merian during a 2009 summer cruise. The data profile includes dissolved oxygen, nitrate, phosphate, silicate, salinity, and temperature from the Davis Strait, Labrador Sea, and North Atlantic Ocean. Arne Körtzinger, Tobias Steinhoff, and Toste Tanhua of GEOMAR collected these observations for the CLIVAR Global Ocean Carbon and Repeat Hydrography Program.
Use Cases
- Modeling ocean carbon uptake based on dissolved inorganic carbon and alkalinity measurements
- Analyzing nutrient distributions (nitrate, phosphate, silicate) for marine ecosystem studies
- Studying water mass properties and circulation using salinity and temperature profiles
- Calibrating biogeochemical models with discrete, profile-based chemical data
Strengths
- Data includes multiple key ocean chemistry variables (DIC, alkalinity, oxygen, nutrients)
- Profile measurements from a specific research cruise (MSM12_3) with known instruments (CTD, Niskin bottles, titrator)
- Spatial coverage spans three distinct oceanic regions (Davis Strait, Labrador Sea, North Atlantic Ocean)
- Temporal coverage is a focused 40-day period in summer 2009
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 cruise track
