During field research work an attempt was made to use an infrared camera in alpine conditions without the use of a plane. The images received as thermal pictures are of high value because they show a continuous record of temperature on the whole water surface. The scale of temperature diversity is very high and amounts to approximately 6 °C. It is necessary to take photos of this type at short time intervals. It will enable the circulation of waters which results in a change in water temperature to be captured. This research will also allow seasonal changes of water temperature to be seized, for example during summer stagnation, water freezing, destruction of the ice layer and also the influence of the coastal zone on shaping thermal conditions in the zone of coastal waters.
