Monitoring Stations

The order of the environmental monitoring stations is very important for marine water areas that characterized by high indentation of the coastline, a significant number of islands and shallows. This article proposes a methodology in order to reduce the number of monitoring stations based on zoning of the water area followed by optimization of the research vessels route. The optimization was performed using the well-known traveling salesman problem algorithm, which was improved for this case. It is shown that this approach allows to reduce the time of one survey by 15–20% on the example of monitoring the oxygen saturation in the White Sea waters.

Kandalaksha graben, located in the water-area of the White sea, is a part of the Onega-Kandalaksha paleorift of the Riphean time of foundation. It is filled with the terrigenous formations of the Terskaya suites ranging from 3 to 8 km by depth, while the age of the rocks of the Terskaya suite is still controversial, and according to different sources, ranges from 1300 to 670 Ma. This means that the time of the formation of Kandalaksha Graben is not precisely defined. In 2016, on the Tersky Bank of the Kola Peninsula, a sample of sandstones of the suite was selected. The age of the rock of 1390±25 Ma, i.e. the boundary of the early and middle Riphean, was determined by the K-Ar isotope method.. This corresponds to the time of the beginning of the stretching of the lithosphere and continental rifting. Quartz-microcline metasomatites formed on sand-shale spit of Terskaya suite in the zone of amethyst deposit of Cape Korablik gave the age of 821±170 Ma, determined by Sm-Nd method, and fluorite of the same rocks gave the age of 690±71 Ma. The last value is close to the age of the basalts from the Onega depression, defined by the same method. These data correspond to the momentum of stretching of the passive Timan margin of the Baltic area at the end of the late Riphean.

Environmental monitoring is an important tool for environmental protection supervision and management. Environmental monitoring can help us effectively understand and master the degree of environmental pollution, and provide data support for putting forward environmental protection measures. Scientific layout and reasonable level of environmental monitoring network design is an essential cornerstone for environmental monitoring, and a significant measure to promote the industry and green sustainable development. This paper systematically analyzed its requirements of monitoring stations in the highway traffic environment monitoring network. First of all, the paper analyzed the influencing factors of regional monitoring stations in the Xinjiang transportation environment monitoring network by referring to the idea of planning the distribution points of the national transportation environment monitoring network, and determines the weight of them by using the analytic hierarchy process (AHP), which lays a foundation for the subsequent selection and determination of environmental monitoring stations. Secondly, the advantage order of ecological monitoring objects’ importance degree was synthetically sorted by the fuzzy comprehensive evaluation method. Finally, the ranking results of the environmental monitoring objects were integrated to determine the number of traffic environmental monitoring stations that need to be built, and the layout of the highway traffic environment monitoring network in Xinjiang was proposed.

In this paper we study the specifics of the population of copepods Scottomyzon gibberum Scott dwell in starfish Asterias rubens L. in Kandalaksha Bay of the White Sea near the N.A.Pertsov White Sea Biological Station. We singled out the "average" most populated starfish size class. The distribution of copepods on the surface and the proportion of individuals in the galls depend on the type of the biotope in which populations of starfish live and salinity of the water. In the area of Polovie islands and "Babie Sea" population of starfish is higher as well as the number of cells in their coelomic fluid. The area of the carapace of copepods in the researched water area varies.

Kandalaksha Gulf

The geological structure of the water area adjacent to the White Sea biological research station of the Moscow State University (the Rugoserskaya bay and the Great Salma strait, the Kandalaksha gulf of the White Sea) was examined for the first time basing on seismoacoustic data. The morphology of top of the Archaean basement, the structure of the Quaternary sedimentary cover and the bottom topography were studied. A sequence of glacial deposits dating back to the last glaciation and a compound sequence of glaciolacustrine, glacial-marine and marine sediments were delineated. Spatial configuration and thickness behavior were examined. It was demonstrated that the recent bottom topography is controlled by the faults, characterized predominantly by north-western and the north-eastern strike, and affecting the entire sedimentary cover including the Holocene sediments.
