Opis:
The authors of the article consider the stone labyrinths as solar calendars. In the center of these structures there are usually already installed gnomons – vertical objects that give shade. Midday shadow points to north, and the change of its length during a year is correlated with the diameter of the arcs of the labyrinth. Points of sunrise / sunset at the equinoxes and solstices are very often fixed in the pattern of the labyrinth, as well as the beginning of the annual cycle. In general, patterns of labyrinths are of the same type, the differences reflect the regional characteristics of illumination, the differences in latitude and topography (shape of the horizon). The uniformity of the technology and the location on the waterways give an opportunity to consider stone labyrinths as ancient elements of local and regional navigation networks.

Opis:
Danger of pollution of water areas of the Sea of Azov and the Kerch Strait from possible technogenic catastrophes is diagnosed as a result of comparison of wind power calculations and the current state of coast of the gulf. Ideas of a uniform West Temryuk stream of deposits are disproved. Three dynamic systems in the east and in the center of a coastal arch and the unidirectional alongshore stream of pollutants and energy in the western segment of the Temryuk gulf are revealed.

Opis:
It is studied the distribution of Hg in bottom sediments of estuaries on the banks of the open water area of the Vistula Lagoon and in the Kaliningrad Sea Canal (KSC) isolated from it. Methods for the determination of Hg: inversive voltammetry and highly sensitive flameless atomic absorption spectrometry. It has been established: from spring to autumn the activation of storms and surge events in the lagoon, intensification of the water flushing regime of the channels ensure a significant Hg decrease in river mouths, but in dynamically weakened KSC conditions - an increase in Hg (from 0.05 to 0.85 mg / kg). In KSC bays, the safe level of Hg (0.3 mg / kg) for the period 2000-2015 was not exceeded (0.008 to 0.216 mg / kg), which indicates a favorable ecological and epidemiological situation. Hg determinations by low-sensitivity methods can be used only in qualitative assessments of the variability in concentrations of any dangerous toxicant. Finding a reliable amount of Hg in river mouths requires the use of highly sensitive methods of analysis.
