Data on the conditions of disrupted and natural ecosystems of Western Siberia in the areas of oil extraction.
Description
Extraction of carbohydrates (including oil), which is crucial for modern civilization, is accompanied with significant negative impact on the biosphere and the planet as a whole, although negative activities associated with carbohydrate extraction are not unavoidable. Currently, oil and oil products are the highest priority pollutants of the environment. Certain territories of oil extraction are matched to the regions of ecological catastrophes. The solutions to ecological problems are complicated by insufficient research of geochemical processes occurring at the transformed natural complexes. Western Siberia is a region of the largest and most intensive oil extraction in Russia. Currently, around 70% of Russian raw hydrocarbon is extracted within Western Siberian lowlands. Presented data was collected during a largescale ecological monitoring of bog ecosystems of Western Siberia in 2007-2009 with a purpose of evaluation and documentation of conditions of disturbed natural complexes in comparison with undisturbed complexes. The main sources of impact on these territories are cluster pads and pipelines. Monitoring sites were located in the areas of oil and highly mineralized water spills and in the areas of exposed to emission flows from cluster pads. The team used GPS to record locations of monitoring sites, described and documented soil incisions as well as documented geobotanical descriptions. Chemo-analytical analysis was carried out for following indicators: pH (water extract), total solids (%, mg/kg), SOM (%), Cl- (mg/kg), Na+ (mg/kg), hydrolytic acidity (mmol / 100g), CEC, % (Al3+, Н+, Na+, Ca-, Mg-), CEC (mmol / 100g), total nitrogen (%), hydrocarbons (g/kg), Ba (mg/kg), V (mg/kg), Fe (mg/kg), Mn (mg/kg), Ni (mg/kg) Zn (mg/kg), SAC (mg-eq/100g). The data can be used by ecologists, pedologists and geobotanists for analysis of the processes of technogenic transformation of forest and taiga bog ecosystems.
