Navigation, surface current, sea surface temperature, wind, and atmospheric pressure data collected by the Mar Mostro during the around-the-world Volvo Ocean Race (VOR) 2011-2012 (http://www.volvooceanrace.com/en/home.html). The Mar Mostro is a 21.5m sail-powered racing yacht that was manned by the Puma Ocean Racing team (sponsored by the PUMA sports apparel company) and powered by Berg Propulsion of Sweden.

Data were provided to the Center for Ocean-Atmospheric Prediction Studies at the Florida State University by Robert Hopkins, Jr. who served as the performance analyst and coach for the Mar Mostro during the 2011-2012 VOR. Co-author for the data was Tom Addis, Navigator and crew member for the team.

Processing Steps
  • Data Type: LATITUDE (measured); Units: degrees N; Observation Type: in situ; Sampling Instrument: GPS; Sampling and Analyzing Method: Raw data selected from two GPS sensors sampling at 10 Hz and 5 Hz respectively.
  • Data Type: LONGITUDE (measured); Units: degrees E; Observation Type: in situ; Sampling Instrument: GPS; Sampling and Analyzing Method: Raw data selected from two GPS sensors sampling at 10 Hz and 5 Hz respectively.
  • Data Type: Boat speed (measured); Units: knot; Observation Type: in situ; Sampling Instrument: Nortek Doppler velocity logger; Sampling and Analyzing Method: The longitudinal velocity from the logger is used as boatspeed. the Nortek internal sampling frequency is 17 Hz, but that is downsample averaged to 4 Hz before we run the transforms on the raw beam velocities. Mind you, these frequencies are MUCH higher than any meaningful speed or leeway changes in the 14.5 tonne boat. The transformed boatspeed value is damped to 5 – 8 sec decaying filter depending on sea state (more damping in rougher seas, user adjustable on board).
  • Data Type: wind speed (true) (measured); Units: knot; Observation Type: in situ; Sampling Instrument: Unknown; Sampling and Analyzing Method: Measured at the mast head at 30 m elevation.
  • Data Type: wind direction (true) (measured); Units: degrees true, from which wind blows; Observation Type: in situ; Sampling Instrument: Unknown; Sampling and Analyzing Method: Measured at the mast head at 30 m elevation.
  • Data Type: course through the water (calculated); Units: degrees true; Observation Type: in situ; Sampling Instrument: Nortek Doppler velocity logger + Ixsea Hydrins IMU; Sampling and Analyzing Method: Value is the sum of the heading + leeway. The atn(Vy/Vx) from the logger provides the leeway angle in degrees, which is added to the boat's heading to arrive at course through the water. Heading is provided by an Ixsea Hydrins IMU.
  • Data Type: speed over ground (measured); Units: knot; Observation Type: in situ; Sampling Instrument: GPS; Sampling and Analyzing Method: The Mar Mostro has two GPS’s sampling at 10 Hz and 5 Hz. We started with the fancy 10 Hz model and ended with the 5 Hz model for reliability reasons. The SOG values are output at only 1 sec intervals. In any case, the GPS output of SOG is damped inside the unit before the crew see the values, then additional damping is applied simply to calm down the displayed values to something reasonable.
  • Data Type: course over ground (measured); Units: degrees T; Observation Type: in situ; Sampling Instrument: GPS; Sampling and Analyzing Method: The Mar Mostro has two GPS’s sampling at 10 Hz and 5 Hz. We started with the fancy 10 Hz model and ended with the 5 Hz model for reliability reasons. The COG values are output at only 1 sec intervals. In any case, the GPS output of COG is damped inside the unit before the crew see the values, then additional damping is applied simply to calm down the displayed values to something reasonable.
  • Data Type: CURRENT DIRECTION (calculated); Units: degrees true, towards which water flows; Observation Type: in situ; Sampling Instrument: Nortek Doppler velocity logger; Sampling and Analyzing Method: Vector difference of through water and over ground directions. The Nortek internal sampling frequency is 17 Hz, but that is downsample averaged to 4 Hz before we run the transforms on the raw beam velocities. Mind you, these frequencies are MUCH higher than any meaningful speed or leeway changes in the 14.5 tonne boat. The transformed boatspeed value is damped to 5 – 8 sec decaying filter depending on sea state (more damping in rougher seas, user adjustable on board) and 8 sec for leeway. Now, that merely describes the filtering on the input vectors. They are differed, and then the output vector of current rate/dir is boxcar averaged to 60 – 120 sec. An average of less than 1 minute is too jumpy. An average of greater than 2 minutes is too sluggish. In coastal racing where there are more abrupt current lines, we use 1 min, else 1 - 2 min for the open ocean. The current rate and direction columns in the data set are calculated and logged onboard as described above.

  • Data Type: SEA SURFACE TEMPERATURE (measured); Units: degrees C; Observation Type: in situ; Sampling Instrument: AirMar DT800; Sampling and Analyzing Method: SST is from the AirMar DT800 (depth sounder with temperature sensor) mounted thru-hull on centerline. Robert describes the sensor as being mounted "at about 75 cm below the water plane," and in a later discussion describes it as being mounted "at about 0.5m depth." The reported SST is raw, no correction, and represents the water temperature at the depth sounder head 75 cm below the surface, but the water that passes that sensor is probably from a higher level due to the way that water is entrained under the forefoot of the hull. The sampling rate is 1 Hz.; Data Quality Information: The accuracy is unknown, other than to say that the manufacturers of sonic devices are careful with their temperature readings, since they impinge directly on depth or speed. The AirMar sensor is specified to an accuracy of +/-0.5C, with a resolution of 0.1C.
  • Data Type: PRESSURE - BAROMETRIC [BAROMETRIC PRESSURE] (measured); Units: hectopascal; Observation Type: in situ; Sampling Instrument: Unknown.
