Historically, a dock intercept process was used to deploy observers in the Northeastern United States groundfish fishery. In this process, the selection of which fishing trips received observer coverage was manually accomplished using pre-defined specifications established by the National Marine Fisheries Service’s Northeast Fisheries Science Center. In May 2010, the management of the northeast groundfish...
Using theoretical cruise paths of known distances, the errors associated with the use of polled GPS data to calculate the distance traveled by fishing vessels were explored. Specific attention was given to how errors vary in response to changes to the polling frequency, cruise path complexity, vessel speed, and GPS error and precision. Simulation results show that distance estimates derived from high-frequency...
