The longitude of the GPS observations of the two trips in our case study of northern fur seals. Both trips started and ended at Bogoslof Island (Alaska) and the horizontal line indicates the longitude −168.035E of the island. The time unit is the proportion of the total time of this trip. Notice the “bridge” structure of these trips, i.e., their difference is small at the beginning and end, but very large in the middle. This “bridge” structure is described by the Brownian Bridge process
