The results of studying spatial-temporal CO2 variations near St. Petersburg during 2014–2017 based on satellite measurements (OSO-2 satellite), ground-based spectroscopic and local measurements are presented. According to satellite data the full amplitude of the spatial-temporal variations for the average CO2 mixing ratio (XCO2) amounted to 57.7 ppm (over 14%). The maximal XCO2 spatial variations during one day of observations (17.03.2015) were 46.8 ppm (more than 10%). Comparison of CO2 satellite and ground-based spectroscopic measurements has shown that ground-based measurements in the NDACC observing system after correction of systematic differences from the TCCON system can be used for validation of satellite measurements. Ground-based local measurements of the near-surface CO2 mixing ratio at Peterhof do not correlate with either spectroscopic ground-based or satellite measurements due to both mesoscale CO2 variations and significantly different spatial averaging kernels of direct and remote measurements.

Selection Of

The problems of modern geological ecology associated with the study of pollution of sediments of water bodies by heavy metals are considered. The Volga River basin is quite heterogeneous, both in geomorphological and hydrological terms, and in thechnogenical development and usage. A fourrank taxonomy is presented for the selection of sites for monitoring, based on a combination of natural, landscape, climatic and thechnogenical factors. To the largest – the highest taxon – sites of the Ist category – bowls of reservoirs with the slopes and the urban zones, industrial and agricultural structures located within them are carried. Within these areas are allocated to smaller taxa, areas category IInd are the industrial and urban zones, areas category IIIrd are the small rivers without significant contamination and areas category IVth to conduct special observations. The examples of special observations in the study of the annual migration of heavy metals in the system «bottom sediments – water column» on the Ivankovo reservoir are highlighted. The investigations were carried out under the conditions of the standard flow rate for this reservoir and in the conditions of slow water exchange.
