| The face of Baikal - Water © A description of Baikal's water & questions concerning its pollution by S.A.Gurulev Pressure of Lake Baikal Water The pressure in the mass of Baikal's water rises one atmosphere every 10 metres. A rise in pressure lowers the temperature at which water has greatest density. So, at the surface the temperature is +3.96 degrees C. In the deepest parts of Baikal pressure reaches a level of 164 atmospheres, the temperature of the water with the maximum density here is close to +0.6 degrees C. In recent years the deep belly of Baikal has been studied with the help of the deep water apparatus, "Pisces". Depth sensors are installed in these apparatus (improved manometers), which measure the depth of submersion of the apparatus using the natural measurement of pressure in water. |
