Query: Surfing on turbulence   Many planktonic organisms are motile and perceive their environment with flow
sensors. Can they use flow sensing to travel faster in turbulence? To address
this question, we consider plankters swimming at constant speed, whose goal is
to move upwards. We propose an analytical behavior that allows plankters to
choose a swimming direction according to the local flow gradients. We show
numerically that such plankters can "surf" on turbulence and reach net vertical
speeds up to twice their swimming speed. This physics-based model suggests that
planktonic organisms can exploit turbulence features for navigation.
