73 years of oceanographic data collected by Japanese ships and research institutes across the Eastern Pacific and Southern Oceans. Measurements include temperature and salinity from bottle casts, high-resolution CTD, and XBT deployments. The National Oceanic and Atmospheric Administration aggregated data from the Japan Maritime Self-Defence Force, Japan Antarctic Research Expedition, and university research vessels.
Use Cases
- Analyze long-term temperature trends in the Pacific Ocean based on the 1931-2003 time range
- Model salinity profiles in the Southern Ocean based on CTD and bottle cast data
- Study vertical ocean structure near the Mariana Trench based on CTD data from Tokyo University
- Validate historical oceanographic models using data from Japanese Antarctic expeditions
Strengths
- 73-year temporal coverage from 1931 to 2003
- Multi-platform data from Japanese military, coast guard, and university research vessels
- Includes high-resolution CTD data alongside traditional bottle casts
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Data may reflect geographic bias inherent to Japanese expedition routes
