| Description |
The ship was in port during these periods and the measurements may be affected by various sources (overhead cranes, anthropogenic sources, etc).
Note: Dates and times were found by looking at the NAV datastream. The standard deviation of pitch, roll, and surge velocity were used to determine when the ship was slowing down to enter port or speeding up to leave port. Thresholds used; pitch (0.01), roll (0.01), surge velocity (3.0) |
