SCIOP's dataset provides monthly statistical summaries of surface ocean currents in seas adjacent to Japan from 1953 to 1994. The data, derived from GEK and ADCP instruments, is aggregated into 1-degree latitude/longitude grids. Each grid includes mean speed, mean direction, sample count, maximum/minimum current, and stability.
Use Cases
- Analyzing seasonal patterns of ocean currents based on monthly statistical summaries
- Mapping mean current direction and speed based on gridded vector data
- Assessing data reliability for specific regions based on the number of samples per grid
- Identifying extreme current events based on maximum and minimum values per grid
- Evaluating current stability over time based on the stability metric
Strengths
- Data spans a 41-year period from 1953 to 1994
- Combines measurements from two instrument types: GEK and ADCP
- Provides multiple statistical metrics per grid: mean speed, direction, sample count, extremes, and stability
Limitations
- Last updated 1994-12-31 23:59:59.999000; 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
