Nidziańska Basin
Polska
Opis:
The north-eastern part of Nidziańska Basin, near Staszów, boasts a large grouping of small but relatively deep lakes of karst origin. In 2010, 26 of them underwent regular measurements of the temperature of their surface layer of water. The results show that although the basins are situated close to each other and the area has similar characteristics, the temperature differs significantly. The thermal differences reach 11.6ºC. The warmest lakes appear to be Lake Łajba, Duży Staw, Lakes Torfowe I and Torfowe II. However, the coldest surface water is in lakes Piąty Staw, a small unnamed lake located near Lake Ciemne and an unnamed lake sandwiched between Lake Szyja and Lake Jasne.The fact that the temperature of the water goes up results directly from solar radiation, which was the strongest in the case of Lake Łajba, located in an open area. However, the coldest basins were located in the central parts of the lakes of the floating peat islands. Those biogenic islands are perfect “insulators”, protecting the water from thermal radiation. Moreover, the lakes which are fed with soligenous water supplies, tend to have a lower temperature.

Opis:
The basic objective of the research was to investigate and determine variations in the physico-chemical properties of the arable layer (Ap) of calcareous soils which belong to the group of lithogenic soils. The above objective was achieved by determining the following physical soil parameters: static and dynamic water resistance of soil aggregates as well as the state of their secondary aggregation following static and dynamic action of water. The above mentioned physico-mechanical properties were determined for wet aggregate models, wet aggregate models subjected to freezing and defreezing and dry "ones", i.e., brought from the appropriate level of moisture to the air-dry state. In order to obtain a comprehensive picture of the properties analysed in the study and their complex evaluation, samples were collected in such a way as to represent the most important and common groups of Rendzinas occurring in Poland. Hence, the material sampled for laboratory analyses developed from various parental rocks.
