The Japan Sea, North Pacific Ocean, and Philippine Sea are covered by surface underway measurements collected from the SOYO-MARU research vessel between May and November 2015. The dataset includes partial pressure of carbon dioxide, salinity, sea surface temperature, and barometric pressure, collected by Tadafumi Ichikawa and Tsuneo Ono of the National Research Institute of Fisheries Science. Data were gathered using a Carbon dioxide (CO2) gas analyzer and other instruments across three specific cruise legs.
Use Cases
- Modeling air-sea carbon dioxide flux based on partial pressure measurements.
- Analyzing correlations between sea surface temperature and carbon dioxide concentrations.
- Studying seasonal ocean carbon dynamics in the Western Pacific based on the 2015 time series.
- Calibrating satellite-derived salinity or sea surface temperature products with in-situ measurements.
Strengths
- Data covers three distinct cruise legs in 2015 (49WB20150508, 49WB20150801, 49WB20151026), providing temporal snapshots.
- Includes key variables for carbon cycle studies: partial pressure of CO2, salinity, sea surface temperature, and barometric pressure.
- Collected by a named research institute (National Research Institute of Fisheries Science) using a specified instrument (CO2 gas analyzer).
Limitations
- Row count and file size are unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
