Kuroshio Current Study Data from East China Sea in 1987

Data from the 1987 Kuroshio Current Study includes station data, XBT, STD, GEK, Acoustic Profiling Current Meter, and DBT measurements. The Japan Oceanographic Data Center submitted the data, which covers the East China Sea and other areas from January to November 1987. The dataset comprises 37 distinct reference numbers (L00797 to L00833), each representing different institutions, ships, and cruise dates.

Use Cases

• Analyze Kuroshio Current velocity and structure using Acoustic Profiling Current Meter (APCM) data.
• Study vertical temperature and salinity profiles from STD (Salinity, Temperature, Depth) casts.
• Map ocean thermal structure using Expendable Bathythermograph (XBT) data across the study region.
• Correlate surface current measurements from GEK (Geomagnetic ElectroKinetograph) data with other oceanographic parameters.

Strengths

• Data spans a 10-month period from January to November 1987.
• Includes 37 distinct data series (reference numbers L00797 to L00833) from multiple institutions and ships.
• Contains multiple complementary data types (station, XBT, STD, GEK, APCM, DBT) for cross-validation.

Limitations

• Data is over 35 years old, limiting its use for studying current ocean conditions.
• Specific row counts, column names, and file sizes are unknown, complicating initial assessment.
• Geographic coverage, while including the East China Sea, may be biased towards specific cruise tracks.
