Аннотация: В работе представлены результаты эхометрических исследований трёх экспедиций ВНИРО в атлантический сектор Антарктики. Объект исследований - миктофиды. Гидроакустические работы в этих экспедициях включали: проведение эхометрических съёмок, изучение поведения скоплений, определение степени наполнения трала и промысловой значимости при облове скоплений миктофид./The article presents data of acoustic surveys from three cruises of VNIRO to the Antarctic Atlantic Sector. Lanternfish were the object of research. Hydroacoustic investigations in these cruises included assessment surveys, behaviour studies, estimates of the accumulation of the catch in the trawl and the evaluation of commercial importance of exploited lanternfish concentrations. Biomass assessments for surveyed areas in different seasons are given. It is noted that summer and summer-autumn periods favour acoustic surveys, while summer is more preferable for fishing operations. The method is suggested for the evaluation of commercial importance of concentrations and control of the catch accumulation in the trawl during fishing operations using echo integration through relevant regression equations.

Аннотация: Antarctic krill (Euphausia superba Dana) is considered a most valuable fishing object in the Antarctic waters. According to some estimates, its stocks totals hundred million tons. Besides, krill makes the basic part of feeding ration for numerous consumers, including sea birds, seals, whales, etc. Hydrochemical conditions in areas of the Antarctic krill concentrations in the Southern Ocean are reviewed. We have identified hydrochemical parameters which allow us to differentiate main water masses in the Antarctic waters (i.e. waters associated Antarctic Circumpolar Current (ACC) vs. water with the high-latitude modification associated with continental seas) and distinguish a zone of their interaction, the Secondary Frontal Zone (SFZ). This zone basically makes the areas of the krill dense concentrations.

Аннотация: Euphausiids (Euphausiacea) are the key species in the trophic structure of ecosystems of the Southern Ocean. The data on the distribution and age structure of Euphausiids larvae were collected during R/V "Polarstern" expedition in January 2011 in the West Antarctic Peninsula region. Three types of distribution were found out among the four Euphausiids species: offshore (T. macrura and E. frigida), inshore (E. crystallorophias) and distribution at the shelf slope (E. superba). The densities of E. superba larvae in 2011 were higher than the results of previous studies in the 70's and 80's. This indicates a high recruitment rates in spite of rapid climatic changes in the Antarctic Peninsula region.

Аннотация: Hydroacoustic observations of Antarctic krill were made during the 27th Antarctic expedition of the RV "Polarstern" in CCAMLR Subareas 48.1, 48.2, 48.5 and 48.6 including in the central part of the Weddell Sea. Hydroacoustic data were collected using two-frequency echo sounder (70 and 120 kHz) "SIMRAD EK 60". Nautical Area Scattering Coefficient (NASC) was used for characteristic of krill density. NASC was calculated from 10 to 300 m depths with EDSU 5 nm. Maximal NASC values (average 44,4+-3,1 m2/n.m2) were recorded in the Antarctic Peninsula region (Subarea 48.1). Increasing of NASC was recorded in regions corresponding to the Antarctic Circumpolar Current, the Coastal Current and the circulation around the Maud Rise. NASC values in the central part of the Weddell Sea (between 15 degrees and 45 degrees W) were extremely low, mainly less than 1 m2/n.m2. Extremely low NASC indicates the absence of krill swarms in the central part of the Weddell Sea and probably connected with large-scale circulation of the Atlantic sector of Antarctica.
