ResumoBoat-mounted Acoustic Doppler Current Profiler (ADCP) measurements were conducted at a full scale salmon farm outside Tórshavn, Faroe Islands. Measurements were conducted over the duration of two days in an oscillating tidal current. The objective was to visualise the flow field in the wake of the salmon farm and make predictions of the velocity reduction from the farm equipment, i.e. cage nets primarily. Kriging was used to interpolate results from measured velocity to a 3-dimensional (3-D) volume of water, including bathymetry data from the farm site. Results indicate that it is possible to visualise the flow field and make prediction of the velocity reduction. Comparison is made with theoretical velocity reduction and there is good agreement with only a 5% difference in the minimum velocity magnitude.
