Tropical Atlantic Ocean Carbon and Hydrographic Measurements from Cruise MT68_3_2006

MT68_3_2006 includes discrete measurements of alkalinity, chlorofluorocarbons, dissolved inorganic carbon, dissolved oxygen, nitrate, nitrite, phosphate, salinity, silicate, sulfur hexafluoride, water temperature, nitrous oxide, and surface underway partial pressure of CO2. The data were collected aboard the R/V Meteor in the North Atlantic Ocean from July 12 to August 6, 2006. Arne Körtzinger, Tobias Steinhoff, and Toste Tanhua of GEOMAR Helmholtz Centre for Ocean Research Kiel collected these data as part of the International CLIVAR Global Ocean Carbon and Repeat Hydrography Program.

Use Cases

• Analyze ocean carbon sequestration based on dissolved inorganic carbon and alkalinity measurements
• Study ocean ventilation and tracer distribution based on chlorofluorocarbon and sulfur hexafluoride data
• Model ocean biogeochemical cycles based on nitrate, phosphate, silicate, and dissolved oxygen profiles
• Monitor surface ocean CO2 exchange based on underway partial pressure of CO2 measurements
• Assess changes in ocean heat and freshwater storage based on hydrographic temperature and salinity profiles

Strengths

• Data covers a specific 25-day cruise in the tropical Atlantic Ocean from 2006-07-12 to 2006-08-06
• Includes measurements of 15 distinct chemical, physical, and biological oceanographic parameters
• Data collection involved specific instruments: Alkalinity titrator, CTD, Coulometer for DIC measurement, and bottle

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 temporal bias inherent to a single ship cruise
