Greenpeace Russia says seismic in the south-eastern part of the Barents Sea, which there are now court "Rosneft", a detrimental effect on the inhabitants of the marine waters, "Rosneft" states that all work is carried out in strict compliance with environmental legislation.
Seismic surveys against fish
"Judgment" Finder 5 "and" Yuzhmorgeologiya "company" Rosneft "conduct seismic surveys in the south-eastern part of the Barents Sea. Rather, they are 2D-Scanning, that is, an initial study of the shelf. Possible to assume that in the coming years, operations in this increase the area so that the sea will cease to be rich in fish, "- said the coordinator of the project Arctic Greenpeace Russia Yevgeny Belyakov.
In the survey area is the North Gulyaevskaya deposit with reserves of oil and 13 million tons, but, as noted by Greenpeace, that amount of oil produced in Russia for ten days. At the same value in a different area — in the winter and spring there are migrating marine mammals — whales, harp seals and Atlantic walruses.
Meanwhile, seismic detrimental effect on marine life as well as the frequency of seismic sounds coincide with the range of the sound sensitivity of fish and marine mammals. They are a danger to themselves as sources of seismic signal (airgun), distributed in the water sound with a frequency up to 250 kHz, at varying intervals, and the subsequent exploratory drilling, creating constant noise pollution at lower frequencies.
Airgun can scare animals, cause them to diseases and even lead to death. Thus, zooplankton, eggs and young fish within one kilometer of the gun die. The scientists found that within a five-kilometer zone is permanently or temporary hearing damage in fish.
Norwegian scientists who conducted the study of the effect of seismic on the ecosystem in the Barents Sea, with the following results: in the course of work in the region greatly reduced the number of commercial fish and marine mammals, as they avoided areas with noise pollution.
Environmentally friendly oil production
The press service of "Rosneft" RIA Novosti said that all work is carried out in strict compliance with environmental legislation.
"Rosneft" conducting seismic surveys in the South-Russian license area in accordance with the license obligations in strict compliance with environmental legislation and exploration plan agreed with all supervisory authorities. Implemented seismic program was approved by the state environmental review. In the 2012 field season at the same time the complex of environmental and fisheries research, "- said the company.
As for measures to protect the environment during exploration, the team of "Rosneft" May 15, 2012 at a meeting of an expert advisory group on the Conservation of Atlantic walrus, organized in the Russian branch of the World Wildlife Fund (WWF) in the Institute of Oceanology. Shirshov, presented the report "Measures for the protection of Atlantic walrus in the production of 3D seismic CDP on the South-Russian license area," which was developed by the specialists of "Rosneft", a subsidiary of the Company — "RN-Shelf Far East" and the contractor — FGUGP "Yuzhmorgeologiya."
The main measures in the seismic survey provides comprehensive monitoring of the environment, work stoppages and subsequent smooth start pnevmoistochnikov in case of animals within five hundred meters of seismic surveys, for baleen whales safety zone increased to 1400 m while limiting power and sizes of sources, they will be located at a considerable distance from the protected islands. Expedition vessels will bypass the feeding areas and clusters of walrus, and a large-capacity vessels are not allowed to come closer than 10 miles to the protected areas. During the execution of marine operations on vessels will be under constant surveillance of marine animals, which will be carried out by qualified experts — biologists and officers of. This work professionals from leading research and fisheries management — VNIRO PINRO SevPINRO, MMBI SPSU and others.
The work program also provides for continuous environmental monitoring on ships to prevent pollution of air and water.
"Thus, the seismic survey in the South-Russian license area is organized according to the plans of" Rosneft "in compliance with all environmental regulations and thorough public discussion of all environmental aspects of the work performed," — stressed in the press-service.
