MAG/AOS/ALL/M1/S1/S2 - Ship in port
DataStreams:magmwacrM1.a1
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)
Measurements:magmwacrM1.a1:
  • Heave: up positive(heave)
  • noise_sky
  • Heading: fron north(yaw)
  • base_time
  • noise_figure
  • Pitch angle of the ship(pitch)
  • Altitude above mean sea level(alt)
  • North latitude(lat)
  • polarization
  • gain
  • Reflectivity(reflectivity)
  • Roll: starboard down positive(roll)
  • gps_timestamp
  • time_offset
  • Spectral Width(spectral_width)
  • time
  • Sway: toward port positive(sway)
  • Pressure, associated geometric height, at altitude, NGM model output(height)
  • East longitude(lon)
  • gps_velocity
  • gps_heading
  • Mean Doppler Velocity(mean_doppler_velocity)
  • Surge: bow forward positive(surge)
