North Pacific Ocean Water Chemistry and Physical Profiles from 1994

PACIFICA_49EW19940115 includes chemical and physical data collected from the BOSEI MARU NO. 2 research vessel in the North Pacific Ocean from 1994-01-15 to 1994-02-04. The data were collected by Masao Fukasawa of JAMSTEC using CTD and bottle instruments during the WOCE P02C cruise. It contains measurements for dissolved oxygen, nitrate+nitrite, phosphate, silicate, salinity, water temperature, potential temperature, and hydrostatic pressure.

Use Cases

• Modeling ocean carbon cycles based on measured chemical parameters like dissolved oxygen and nitrate.
• Analyzing water mass structure and circulation based on CTD-derived temperature and salinity profiles.
• Calibrating biogeochemical models using phosphate and silicate concentration data.
• Studying historical ocean conditions in the North Pacific during the 1994 time period.

Strengths

• Data collected during a recognized international project (PACIFICA) supported by PICES.
• Includes multiple core oceanographic variables (8 parameters are listed).
• Provides a specific temporal snapshot from a 21-day cruise in January-February 1994.

Limitations

• Last updated 1994-02-04 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
