1. MULTIPLE ACCESS CENTER FOR SATELLITE MONITORING OF THE ENVIRONMENT OF FEB RAS

Head of the Center - Academician V.A. Levin

Main research directions

Monitoring of dynamic objects and processes of the ocean and the atmosphere on the basis of satellite monitoring of the environment to render information support of scientific research and other activities of the FEB RAS Institutes and other organizations in the field of ocean and atmosphere physics, oceanology, meteorology and marine biology.

Principal results

Supply of instantaneous, average and compositional fields of: sea surface temperatures, thermal structures, surface currents velocities, dynamic and spatial characteristics of oceanic eddies, thermal images of land, clouds, etc. through www.satellite.dvo.ru.
Satellite information provided by the Center is successfully used by the TINRO (Pacific Institute of Fishing Industry and Oceanography) for making monthly, quarterly and yearly forecasts of oceanological conditions, as well as forecasts of oceanological conditions of fishing: herring, pollack, salmon, saury and king crab (fishing season forecasts).
In fact, all yearly oceanographic overseas expeditions, both arranged by FEB RAS and international ones, get online satellite information support for pinpoint navigation to the objects under study - eddies, flows, currents, as well as for scientific research.
Within the framework of the UNESCO IOC/WESTPAC/NGSST project a method was created to calculate thermal oceanic structures in the form of dominant orientations of brightness contrasts used for estimating directions of surface current speed and automatic eddy recognition.

The phenomenon of In magic cluster doping on Si(100) has been discovered.
An array of nanoelements in the form of silicon nanotubes doped by beryllium atoms which appeared as a result of the interaction between beryllium and Si(111) surface has been found.
Low-temperature phase changes in Tl/Si(100) and Tl/Ge(100) systems were discovered.
A research was made into molecular beam epitaxy of silicon on Fe disilicide islands formed on the surface of Si(111)7x7 and Si(100)2x1 at 600-800 C. Optimal growth temperature (700 C) on the surface of Si(100) has been determined and data on the structure of silicon and embedded -FeSi2 nanocrystallites (NCs) for the both surfaces have been obtained.
Phonon structure of ingrown multi-layer samples has been investigated on the basis of the analysis of 2-phonon and 3-phonon resonances in silicon and Mg2Si.
An investigation has been made into the morphology, optical properties, crystal and electronic structure of monocrystal silicon after plasma treatment depending on the initial tension of the magnetoplasma compressor (MPC). First data have been obtained on electronic structure parameters and parametric variations in the crystal structure of silicon after its treatment with plasma flux.

Principal results

Research was made into the passage of aerosol to the water area of Peter the Great Bay and to the atmosphere above the city of Vladivostok in the period of sandstorms in the Gobi desert in 2005-2006. Aerosol concentration during the most active period was estimated, and aerosol paths (altitudinal distribution) were determined.
Sub-satellite lidar measurements are taken. A comparative analysis of aerosol probing data obtained with a MODIS scanner and with a space lidar installed on the CALIPSO satellite is made. The works are performed within the framework of the international project No. B-1063 "Atmospheric Aerosol and Ozone Monitoring in the Commonwealth of Independent States" being implemented by the International Science and Technology Center (ISTC) using the lidar station network (Cis LiNet).
In the Center's lidar station an ozone lidar is being installed to measure the altitudinal distribution of the concentration of tropospheric and stratospheric ozone and meteorological parameters of the atmosphere.
The lidar station is a part of the CisNet lidar network, which operates within the international ISTC project.
A brand new class of silicon sponge spicula biocrystals was discovered and investigated.
A research was made into the processes of dynamic scattering of coherent radiation in liquid-phase nanocomposites.
