SUMMARY:Thomas Steinmann (IRBI\, CNRS\, Tours): Singularity of the water st
 rider propulsion mechanisms
DESCRIPTION:Thomas Steinmann: Our understanding of animal locomotion in air
  and water has progressed considerably\, based on studies of their wakes. 
 Wake vortices are the hallmarks of momentum transfer and enable an inverse
  inference of the forces applied by animals. Such approach has recently be
 en extended to locomotion at the air–water interface\, focusing on the f
 amiliar water striders and their dual hallmarks\, surface capillary waves 
 and bulk water vortices\, produced by their paddling legs. However\, the p
 rincipal mechanisms of propulsion used in this type of locomotion remain a
  matter of debate. We confirm that the main force driving propulsion is th
 e capillary force resulting from surface tension\, and that interface rela
 xation makes a major contribution to the increase in vorticity of the wate
 r bulk. There is therefore no one-to-one mapping between forces and hallma
 rks in the fluid. Locomotion at the air–water interface for animals with
  virtual oars much larger than the size of their legs thus requires specif
 ic treatment outside the existing framework based on immersed propulsive a
 ppendices.\n\n\nDOI: https://doi.org/10.1017/jfm.2021.156\n\nIOSSB Seminar
