Description
Monitoring a tide gage to compare digitally collected and transmitted readings tto visual observation. The square instrument on a tripod transmits tidalinformation to a GOES satellite which in turn downloads to a NOAACO-OPS processing facility. The round instrument on the yellow tripod is a GPSreceiver which is used to correct GPS data acquired during launch hydrography. (Image credit: Crew and Officers of the NOAA Ship FAIRWEATHER)
