Some time back, I worked on research vessels that deployed buoys on the equator for climate monitoring. One of my duties was to plan the deployments, which required determining set and drift over 6 or 8 hours as we laid out the cable before dropping the anchor. We’d recover the old buoy the evening before then deploy in the morning. Monitoring the ship’s set and drift as well as using the Acoustic Doppler Current Profiler, I noticed that the currents I planned for the previous evening were not there in the AM. I pointed this out the PhD and MS oceanographers aboard since I’d never heard mention of a diurnal nature in Equatorial currents. All but one emphatically told me that there was no diurnal nature in direct opposition to the sensor in front of them and the actual real world movement of the ship. The one was happy to have found someone else who didn’t deny the facts before them.

This was not the first time I’d had the “scientists” refuse reality but it was disorientating to have so many science types, so ardently deny what was before their lying eyes. I was aided greatly by my own real science education in physics where I predicted the drift of the ship taking into account the diurnal changes and ended up where I expected. For the curious, the “official” equatorial current would reassert itself a couple of hours prior to local apparent noon. Building my current model with these real world details, I achieved very good accuracy on dozens of deployments.
