摘要：One of the fundamental states of the sea surface is its heave.Despite of years of the intense scientific inquiry,no clear understanding of the influence of this aspect on the dynamics of the sea environment has emerged.The separation of two nearby fluid elements which one may observed for example as a free floating of small objects on the sea surface (rescuers on the rough sea or small research vessels) is caused by the interaction of different components.On the other hand one may say that the heave of the sea is also a summary interaction of a few components describing the dynamics of the sea.Therefore it is the most important aspect,which influenced the dispersion phenomenon.This observation has important consequences for many different problems as for example conducting Search and Rescue missions and using unmanned ships.We would like to present results of our experiment focused on finding the answer to question about nature of the heave of the sea and its influence on safety of Unmanned Surface Vessels (USV).
