Application of the gravimetric method in the study of paleoincisions on the territory of the Kaliningrad region

Abstract

This paper summarizes the results of gravity surveys conducted across two palaeoincisions cut into the sub-Quaternary surface in the coastal area of the Kaliningrad region near Svetlogorsk. Strong local negative anomalies caused by the palaeoincisions are observed on the gravity anomaly profiles. The analysis of the palaeoincision's spatial distribution by using gravity data assumed that there is the system of intersecting V-shaped depressions rather than individual paleostructures buried in the subsurface.

Microelement content in lichen hypogymnia physodes in the forests of the Kaliningrad region

Abstract

Samples of epiphytic lichens Hypogymnia physodes were selected in the forests of the Kaliningrad region. Content of Fe, Cu, Zn, Pb, Cd, Ni, Ag, Sr, Rb in the lichen thallus was determined by atomic absorption and X-ray fluorescence analysis. The chemical analysis of elements resulted in the maps of spatial patterns of metals distribution. It is proposed to use the data as a "reference point" for monitoring air pollution research in the Kaliningrad region.

Modelling long-term dynamics of humus content in the mixed forests soils in the Pregel River Basin

Abstract

The long-term dynamics of humus in the mixed forests soils of in the Pregolya River Basin was modeled and analyzed for 1960—2015. Evapotranspiration values were calculated and a dynamics analysis of this parameter for period 1960—2015 was carried out. The impact of changes in meteorological factors on dynamics of forest phytomass has been defined.
