The Laboratory conducts geological-geophysical studies
of deep ocean floor, interpretation of acquisited data, creation of relief
and sedimentary cover formation models, creation of maps, manuals, databases.
Reference directions of our investigations are instituted by the most urgent
problems in the field of World ocean lithosphere studies, and also will
be realized proceeding from professional concerns of the employees. Laboratory
involves - geomorphologists, geophysicists, cartographers, geologists,
engineers in the field of electronics and mechanics. All
directions are interdependent. To us it is represented, that
the ocean research should be based only on all-up analysis of the miscellaneous
data, that causes the greatest veracity of the deductions, and, that most
important, greatest possible consistence as deductions and their consequences.
It obviously follows from that fact, that the Earth is the unique open-ended
system of a highest extent of complication, in which one detailed and authentic
learning of objects or properties can not be reached without development
of adjacent areas and appeal to adjacent disciplines. For want of it we
forecast only general purposes of studies, but in their result are possible
extremely unexpected deductions... Main Objects of Researches: Transform faults, including their passive non-thrusting parts, mid
ocean ridge, volcanic structures of the Atlantic ocean.
Main Approach of Researches: Statistical and visual - heuristic analysis of geographically referenced
heterogeneous information in intercoupling with main ocean patterns on
the basis of electronic database performance.
Main Directions of Researches: 1.Geomorphology of deep-ocean floor.
Includes echosounding survey, progressing of methods of gathering
and data processing. Discovering of underwater relief formation processes.
2.Cartography. Constructing of
bathymetric, geomorphologic, tectonic and other map types as a basis
for tectonic and geodynamic interpretations. Creation of computer maps
and GIS-projects on deep water parts of ocean.
3.Ocean Tectonics. Discovery of
an oceanic crust top part patterns and understanding its origin.
4.Analysis of Geophysical Data.
Acquisition and data processing of a baseline set of geophysical survey
in the ocean: a complete set of echosounding parameters, single-channel
seismic profiling on velocities of 10-12 knots, magnetometry, gravimetry.
Gathering of all accessible geophysical data in opened sources for complement
of the own data and creation its maximum authentic data presence review
for objects on collection of interdependent characteristics. Data processing
by known algorithms and programs, and creation of new ones with the purpose
of geologic selfdescriptiveness of studies increase.
5.Upgrade and Creation of New Engineering
for Seismic Profiling. The seismic methods are key for knowledge of
sedimentary cover patterns. The single-channel profiling allows to conduct
on velocities 10-12 knots survey with penetration up to about three seconds
on formation. Perfecting of engineering and the methodic serves all components
of seismic profiling: streamer, pneumatic energy sources (air guns), systems
of acquisiting and accumulation of the information, programs for automatic
6. Computer know-hows. Determination
of optimum configurations for computers, choice of software, creation of
the own methods of miscellaneous digital data processing and programs,
optimizing work capacity of station as a whole and compatibility
of its various logical components. Communal orientation of station logical
components to GIS-system under observance of a baseline principle: realization
of maximum effective solutions for each step of data processing by selection
(or creation) of the most eligible software.
7.Terminology. Without distinct
and clear scientific language cannot be achieved a success in mutual understanding
between the specialists in knowledge of structure and composition of deep-ocean
floor. It is important for compiling legends to maps of the various contents.
The activity is conducted in frameworks of the GEBCO project (standardizing
of the terms).
8.Toponimics. The titles
of the underwater relief forms, besides the address function, allow to
fasten a priority in studies of diverse objects. Creation of databases
on toponimics and geographical names, and also dictionaries of geographic
titles and terms in marine areas is necessary for geology and standardizing
of their usage in scientific and cartographical editions.
9.Databases. Gathering, acquisiting,
systematization and editing of miscellaneous information, which is stored
as several thematic databases and combined compilations.
