Arctic Ocean Carbon Chemistry and Hydrographic Profiles from 2002

Discrete sample and profile data collected from the MIRAI research vessel in the Arctic Ocean, Beaufort Sea, Bering Sea, and Northwest Passage from August 22 to October 10, 2002. The dataset includes measurements of dissolved inorganic carbon, alkalinity, nutrients, chlorophyll, and hydrographic variables like salinity and temperature. Data were collected by researchers from JAMSTEC and the Meteorological Research Institute as part of the PACIFICA project.

Use Cases

• Modeling ocean acidification impacts based on dissolved inorganic carbon and alkalinity measurements.
• Studying nutrient dynamics in Arctic waters based on nitrate, phosphate, and silicate data.
• Analyzing water mass properties and stratification based on CTD-derived salinity, temperature, and pressure profiles.
• Investigating phytoplankton biomass distribution based on chlorophyll a measurements.

Strengths

• Includes 14 key oceanographic parameters, such as dissolved inorganic carbon, alkalinity, and a suite of nutrients.
• Data collected during a specific cruise (MR02-K05 Leg 1) over a defined 50-day period in 2002.
• Spatial coverage spans multiple Arctic and sub-Arctic seas: the Arctic Ocean, Beaufort Sea, Bering Sea, and Northwest Passage.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Data may reflect temporal and geographic bias inherent to a single research cruise.
