Figure B4. Two-month trajectories (left column) for passive particles released at the mouth of Northeast Channel in the seasonal-mean flow fields. Trajectories are shown for those particles deemed to have entered the Gulf of Maine (those that cross the sill in Northeast Channel and remain in the Gulf for at least 30 days) and only half of these are shown for clarity. The initial vertical positions of the successful particles are shown in the right column (triangles for those reaching Jordan Basin and circles otherwise). The right column also shows the seasonal-mean velocity (cm/s) normal to the release line (positive to the northwest).
