JCOPE-T ocean current forecasting in support of Expedition 380 operations
  This web page provides some results from JCOPE-T ocean modeling system, selected for purposes of supporting JAMSTEC "Chikyu" drilling ship operations during Expedition 380, January 15 - February 25, 2018. Results are presented around and for the drilling point C0006 location at 33°01.63905'N, 136°47.6470'E marked by large black dot on the ocean current maps.
Data of two models: JCOPE-T-EAS for wider region of East-Asian Marginal Seas and JCOPE-T-JCW (ne73) for smaller region of Japan Coastal Waters are included. Difference between two model results is a measure of ocean forecast uncertanties (error).
Forecasts are updated almost daily creating new bulletins with ~10 days forward predictions. Some bulletins could be skipped and some missing in case of computer system maintenance.
Special Best Estimates bulletin provides history of surface ocean nowcasts followed by recent forecasts. On the archived nowcast maps by purple line is plotted weekly-mean position of Kuroshio axis as reported by MIRC (Marine Information Research Center) observational data analysis if such data are available.
Keyboard keys could be used for navigation in time. To use it, move the focus (click mouse) on background and the "N" or "n" keys will step on one hour forward, when "P" or "p" - one hour backward.
You can download extracted from modeling results velocity data in CSV format for the fixed ADCP location from http://www.jamstec.go.jp/jcope/data/chikyu.2018.01/ web page.
