Arctic Ocean Carbon and Hydrographic Measurements from the MIRAI Cruise, 2004

Discrete sample and profile data collected from the MIRAI research vessel in the Arctic Ocean and Beaufort Sea from September 1 to October 13, 2004. The dataset includes measurements for alkalinity, temperature, salinity, dissolved oxygen, nutrients, chlorophyll a, and chlorofluorocarbons. Data were collected by researchers from the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) as part of the PACIFICA project.

Use Cases

• Modeling ocean carbon uptake and acidification based on total alkalinity and DIC measurements.
• Studying Arctic water mass formation and circulation using CFC tracers and hydrographic data.
• Analyzing nutrient-phytoplankton dynamics based on nitrate, phosphate, silicate, and chlorophyll a concentrations.
• Investigating methane sources and sinks in the Arctic Ocean based on CH4 measurements.

Strengths

• Data includes 17 distinct chemical, biological, and physical parameters for a focused Arctic region.
• Measurements were collected over a 43-day period in 2004, providing a temporal snapshot.
• Data collection is attributed to specific researchers and institutions (JAMSTEC) and is part of the defined PACIFICA project.

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 bias inherent to a single cruise in 2004.
