This dataset contains both "raw" and interpolated ship position and velocity measurements from the Des Groseillers during the SHEBA project. The logbooks of the Des Groseillers for the period of the SHEBA Field Experiment were photocopied by the Canadian Coast Guard and provided to the SHEBA Project Office. The date, time, GPS position and Gyro heading were entered into a computer file at the SPO. These raw data were plotted for inspection and compared with other datasets including the SPO observer logbooks, and Miles McPhee's GPS time series for the Ocean City. Based on these plots and comparisons, obvious errors of logbook entries were identified and corrected where possible. The position data were interpolated using a cubic spline to estimate the position and velocity components at hourly intervals. The spline passes through the corrected raw positions in a five-day window centered on each hourly interpolation time. Upon ordering, the user will receive both the raw data file and the interpolated data.
