From August 21 to September 29, 2006, chemical, optical, and physical profile data were collected from the R/V Mirai in the Bering and Chukchi Seas. The dataset includes measurements of dissolved inorganic carbon, total alkalinity, pH, nutrients, oxygen, and temperature from discrete bottle samples and CTD casts. It was collected by Naomi Harada of JAMSTEC as part of the PACIFICA project, an international synthesis effort for Pacific Ocean interior carbon data.
Use Cases
- Modeling ocean acidification dynamics based on DIC, pH, and alkalinity measurements.
- Studying nutrient cycling and primary productivity based on nitrate, phosphate, silicate, and ammonium data.
- Analyzing water mass properties and oceanographic profiles based on CTD-derived temperature, salinity, and sigma-t.
- Calibrating biogeochemical models with in-situ carbon system parameters from the Pacific Ocean.
Strengths
- Data includes a multi-parameter suite of 14+ oceanographic variables for carbon system analysis.
- Measurements are from a defined research cruise (MR06-04 Leg 2) over a focused 40-day period in 2006.
- Collected as part of the international PACIFICA project for data synthesis and quality assurance.
Limitations
- Row count and dataset size are unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
