Japanese Oceanographic Observations from Multiple Agencies (2018)

Japan's coastal and marine observation data for 2018, processed by the Japan Oceanographic Data Center (JODC). The collection aggregates measurements from seven major Japanese agencies and institutions, including the Japan Meteorological Agency and the Japan Coast Guard. Data spans observations from 2004 to 2018.

Use Cases

• Analyze temporal trends in sea surface temperature from Japan Meteorological Agency records (2014, 2016).
• Correlate salinity and nutrient measurements from Japan Fisheries Research and Education Agency data (2004-2015) with fishery yields.
• Model coastal water properties using spatial observation points from Japan Coast Guard and Maritime Self Defense Force datasets.
• Validate satellite-derived ocean color data with in-situ chlorophyll readings from Mie Prefectural Fisheries High School observations (2016-2017).
• Study polar ocean conditions near Japan using temperature and salinity profiles from National Institute of Polar Research data (2017, 2018).

Strengths

• Aggregates data from seven authoritative Japanese governmental and research institutions.
• Provides a multi-year temporal coverage from 2004 to 2018 across contributing sources.
• Includes specialized observations from polar research and fisheries education agencies.

Limitations

• Exact row count, column names, and measurement variables are not specified.
• Geographic coverage is biased towards Japanese coastal waters and regions of interest to contributing agencies.
• Data is not updated beyond the 2018 processing date, limiting recency.
