Geologiczno-inżynierska charakterystyka gruntów antropogenicznych historycznej zabudowy Lwowa

Wołoszyn P.

Przegląd Geologiczny

2017

Vol. 65, nr 10/2

890--894

In the article the conditions of occurrence, spatial distribution, genesis, composition and properties of technogenic soils in central part of Lviv were described. It was established that these soils cover the study area as a solid layer with thickness from 2.0-4.0 to 6.0-9.0 m. They are characterized by a high degree ofspatial heterogeneity, low values of mechanical properties and specific sensitivity caused by the presence of ephemeral elements (makrooorganic substance, soluble salts etc.) in their composition that are very susceptible to changes in air-humi-dity regime.

Observations of presumable groundwater seepage occurrence in Puck Bay (the Baltic Sea)

We report the results of recent field measurements of seawater thermohaline structure and transparency carried out in early summer 2014 in Puck Bay. Near-bottom, less saline waters occurred almost in the entire study area. Their occurrence in the shallow part of Puck Bay was accompanied by an increase in the seawater transparency. The most likely explanation of these observations is a submarine fresh groundwater discharge.

Upwelling intrusion into shallow Puck Lagoon, a part of Puck Bay (the Baltic Sea) [commun.]

Matciak M., Nowacki J., Krzymiński W.

Oceanological and Hydrobiological Studies

2011

Vol. 40, No.2

108-111

In this short communication we present the results of field measurements which show the incidence of waters originating from the deeper layers of Puck Bay in shallow Puck Lagoon. The reason for such a situation is the occurrence of a small-scale upwelling. This phenomenon may play a significant role in shaping the ecosystem conditions of Puck Lagoon, which is unique in terms of its natural values.
