…We have recently had the opportunity to compare your charts to a set of proprietary measured current data we collected over a one year period in the northern Gulf of Mexico. Since we were recording data within subsurface moored instruments recovered only every few months, this was a completely blind test of your real-time charts to measurements. Basically we are extremely impressed. Your charts decisively depicted the features causing the periods of strong upper layer currents we measured. We are not sure how you do it but want to congratulate you on making a fine contribution to real-time oceanography.
