• in the morning figured out how to resolve problem that grey loudspeaker in top of remote control prevents from taking off: calibrate gyros and then it works
  • main problem of the last days: mounted the propeller wrong (disappointed face ); accidentially mounted all 4 wrong this time and we did not take off, but got pressed into the ground, so we noticed
  • after solving the problem, we were super motivated to take off right after lunch
  • start measurements at 12:48:30
  • made a roughly 150x150m^2 survey partly over the ROV non-walking area and partly further away from the ship
  • all went very well
  • stopped program, changed batteries, started measurement again and flew two vertical profiles: one over ROV area, one further out
  • first profile 5m, 10m, 15m, 20m, 25n, 30m, 40m, 50m, 60m
  • forgot to lift legs of SPECTRA until 15m
  • second profile other way 60m, 50m, 40m, 30m, 20m, 10m, 5m
  • stopped program again and had to run to bear guard
  • very little drift of the floe and almost no wind today
  • sunny with no clouds
  • data could be read out via VNC WLAN connection
  • struggle with SD card of Camera
