abstract:
The analysis presented in the paper showed the features of the course of the ground temperature on the Polish coast of the Baltic Sea. Depending on the season, two types of vertical temperature profiles may be recognized. During the cold part of the year (October-February) the most dominant type of vertical temperature stratification is the one proving the loss of heat from the shallowest strata to the air and its replacement by influx from the deeper strata. On the other hand, during the warm season (April-August) the highest temperature occurs in the upper part of the profile and standard deviation values are the highest. In March and September there is quasi-isothermal stratification. During prevailing part of the year positive temperature dominates at all depths. There is a risk of freezing at the depth below 50 cm from December to March.
