MAG/MPL/M1 - Instrument problem causing pulse failure
DataStreams:magmplpolfsM1.b1
Description:
False triggering of the laser causes ingest to misinterpret beginning of data.  Moreover, 
laser does not produce full pulse, so there is no reliable data.

MAG/AOS/ALL/M1/S1/S2 - Ship in port
DataStreams:magmplpolfsM1.b1
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)
