This video is a demonstration of a “transiting study”.  The animals are trained to swim alongside the boat at set speeds or for set distances.  This can be used to compare how much energy it takes to swim horizontally vs. how much energy it takes to dive.  We finished up the transiting portion of the study a few months ago.  We will be starting the comparative dive portion in a few weeks.

Boat follows are a great way to maintain animal fitness and open water training.  We use this technique on weekends and between studies.
