  1. Magnitude and angle of the flow is directly measured and compared to an a priori known oceanographic flow model
  2. No direct field measurements required. Inference indirectly via localization, using distance and/or bearing measurements
  3. Distributed localization is considered which is considered sub-optimal in the scenario considered in this work due to the availability of all data in the FC
  4. AWGN corrupted positions estimates are assumed
  5. §Affine dynamics are considered
  6. Position-independent RVs whose parameters are fixed a priori are used instead of spatial field
  7. Refers to the case where the environment’s effect on the agents’ motion is considered
