Hydrographer Graduation
The graduation of young officer-hydrographers took place at the Saint-Petersburg Naval Institute on June 18th. Awards are made annually by the HSR Council of honorary diplomas of the Hydrographic Society to the best graduates, with a view to stimulating interest in a hydrographic qualification. This time the Honorary ‘Professor A.P. Belobrov Diploma’ (specialisation - hydrography) was awarded to graduate Eugeny Makarov; the Honorary ‘Professor V.A. Snezhinskiy Diploma’ (specialisation - hydro-meteorology) was given to graduate Andrey Dontsu. HSR president Prof. Dr N. Neronov presented the honorary diplomas and monetary premiums of 1,000 roubles during a solemn graduation ceremony for young officers.
Meeting Ukrainian Scientist
On 20 June the HSR has organised a meeting in the form of a round-table at which Society member Dr Rudolf Greku from the Institute of Geological Sciences of the National Academy of Sciences of Ukraine gave an interesting presentation. In ‘Application of satellite methods for definition of topography, dynamics (changes) and physical properties of terrestrial, ice and water surfaces’ Dr Greku described the regional geoid topographies of the Black Sea and Bellingshausen Sea (Western Antarctic). These were computed with ERS1/2 satellite altimeter data (ESA’s AO358 Project) to determine features of seasonal currents and identify hydrocarbon deposits at the shelf.
Dr Greku demonstrated a scheme (Figure 1) giving detailed geoid topography of the Black Sea and Azov Sea with a contour interval of 0.5m. It was possible to see that heights of the sea surface topography (geoid) varied from 34m up to 12m along latitude 430N between western and eastern coasts. Antarctic topography and movement of Antarctic ice streams were determined with Synthetic Aperture Radar (SAR) images using interferometric processing. A fragment of the Flask Glacier at the Antarctic Peninsula from the ERS2 SAR image is shown in Figure 2 and completed by a 3D image (Figure 3). Separated small flows are combined in the common Flask Glacier, which has an extension of 30km from the snow plateau height of 1,700-1,800m up to the Weddell Sea. The width of the flow between bordering peaks is 1,300-1,600m. The depth of the valley is 100-150m (Figures 2 and 3).
The HSR members and employees of the Oceanographic Centre of the Ministry of Defence of Russia attending the meeting listened with itnerest to the presentation, asked questions and vented their opinions on the theme.
