Project summary

The main objective of the project is to develop new mathematical methods and multifunctional software for ecological and geodynamic monitoring of natural objects. The basic idea of the project consists of the development and application of new methods (once invented for military purposes) of satellite imagery analysis, which also employ unique data on temporal variations of the Earth’s gravity field, as provided by the new satellite system GRACE. Launched in March 2002, the system increases the accuracy of gravity field measurements by several orders of magnitude and, for the first time, it permits registration of gravity field temporal variations. This opens new opportunities for using these data in geoecology and geodynamics.

The scope of Project activities can be briefly described as follows:

1) To update existing and to create new mathematical methods of satellite imagery analysis, based on the latest developments of the State Research Institute of Aviation Systems (SRIAS) in fields of selective morphology, and methods of structural imagery analysis, developed at the Institute of Geoecology (IGE).

2) To develop new, high-accuracy methods of analysis of the temporal variations of the Earth’s gravity field, including new methods of joint interpretation based on geodynamical models. These methods will allow joint inversion of various geophysical data, including data derived from analysis of satellite imagery (for example, data on changes of contours of large water reservoirs).

3) To create new analytical and numerical models of the deformation of the Earth’s crust and to test these models and new methods of interpretation based on them, using detailed geophysical data from the on-ground test areas. Work on developing these models will largely rely on new analytical solutions of elasticity theory problems, including solutions for singular domains, which have recently been obtained in SRIAS. One of the project's most important objectives is to study connections between gravity field variations and short-period variations of the Earth’s crust state of stress. A method for calculating short-term variations of the state of stress is being developed in the United Institute of Physics of the Earth, UIPE.

4) To create, on the basis of methods to be developed, new software and to test it using different data. Methods of ecological monitoring will be tested using ground data from several objects, including the Caspian and Aral seas, Lake Baikal, pipeline right-of-way areas, oil and gas production areas, regions of thermokarst development. Testing of the new geodynamic monitoring methods will involve data obtained in test areas located in tectonically-active zones, where gravity and magnetic fields are regularly measured and earthquake catalogues, data on horizontal and vertical Earth’ surface displacements and ground water dynamics are available. This will help to assess the accuracy and reliability of the new methods of satellite data interpretation.

The project will achieve progress in a number of fundamental issues, including:

– new methods of imagery analysis;

– development of a theory of interpretation of fundamentally novel data on gravity field temporal variations;
– new geodynamic models of the Earth’s crust deformations and new methods for monitoring short-period variations of its state of stress;
– study of the interrelations between gravity field temporal variations and variations of the Earth’s crust state of stress and seismic activity.

The project is expected to produce the following practically valuable results:

– creation of new highly-efficient software for various aspects of ecological and geodynamic monitoring;

– formulation of practical recommendations for application of the newly developed methods;
– obtaining results on ecological and geodynamic monitoring of several natural objects.
The introduction of the new methods for analyzing satellite imagery will organize automated and highly-efficient monitoring over vast territories and, hence, it will considerably reduce the required amount of above-ground works, saving the cost of monitoring. The new methods of joint interpretation of temporal variations of gravity field (including those using data obtained from analysis of satellite imagery and geodynamic models) are of particular importance for geodynamic monitoring of seismically active zones and for studying various geodynamic processes.
