*“SOA is "Speed of Advance" and is in knots (nautical miles of 6076 feet/hour).  It would be computed by calculating the distance between the positions in the previous and current SEAS (Shipboard Environmental data Acquisition System) and dividing by the time between the reports (generally 6 hours). SOA would be meaningful for a vessel going from one place to another but generally would not for an oceanographic vessel doing work “on-station”  since the ship is operating at various courses and speeds during the 6 hour period.”
