    Assessment of the effect of absence of spawning on the fish-farming and biological characteristics of Siberian sturgeon Acipenser baerii (Brandt, 1869) offspring (2022)
    Russian Federal Research Institute of Fisheries and Oceanography (VNIRO) | Moscow (Russia)
    Details
    Publication Date: 2022-12-20
    Description: The article presents the results of studies on the effect of spawning season absence of female Siberian sturgeon of the Lena population on the fish-biological characteristics of the experimental group, as well as the grown-up juveniles in the conditions of industrial farms. The offspring of experimental females that underwent the resorption process, despite the lowest weight of embryos at hatching, maintained a high growth rate throughout the entire rearing period, comparable with juveniles of control groups.
    Description: Представлены результаты исследований о влиянии пропуска нерестового сезона у самок сибирского осетра ленской популяции на рыбоводно-биологические характеристики экспериментальной группы, а также подрощенной молоди в условиях индустриальных хозяйств. Потомство опытной самки, прошедшей процесс резорбции, несмотря на самую низкую массу эмбрионов при вылуплении, на всём протяжении выращивания сохраняло высокий темп роста, сравнимый с молодью контрольных групп.

    Assessment of the influence of temperature on the formation of the Eastern and Western Kamchatka pink salmon population in different life periods (2022)
    Russian Federal Research Institute of Fisheries and Oceanography (VNIRO) | Moscow (Russia)
    Details
    Publication Date: 2022-12-20
    Description: The article presents the results of a comparative analysis of some databases describing SST (sea surface temperature) along the coast of Western Kamchatka with data from domestic weather stations carried out in the villages of Bolsheretsk, Icha, Sobolevo and Ozernovsky. These weather stations monitored air temperature and, in some years, water temperature in adjacent coastal areas. Databases ("10-days-SST", "MGDSST", "HIMSST") that adequately describe the actual curves of water temperature in the coastal area and air temperature in the area of concentration of the main spawning water basins and watercourses (ECMWF V5) have been identified. The selected databases were used to develop long-term series of temperature characteristics in the Kamchatka mainland and some areas of the Bering and Okhotsk Seas used by Western and Northeastern Kamchatka pink salmon at different stages of its life cycle.
    Description: Проведен сравнительный анализ некоторых баз данных (БД) описывающих SST (температуру поверхности воды) вдоль побережья западной Камчатки с данными отечественных метеостанций поселков Большерецк, Ича, Соболево и Озерновский, осуществлявших мониторинг температуры воздуха и в отдельные годы температуры воды в прилегающих участках прибрежья. Выявлены БД («10-days-SST», «MGDSST», «HIMSST») адекватно описывающие фактический ход температуры воды в прибрежье и температуры воздуха в районе концентрации основных нерестовых водоемов и водотоков (ECMWF V5). Выбранные базы данных использовались для построения продолжительных рядов температурных характеристик в материковой части Камчатки и некоторых районов Берингова и Охотского морей, используемых горбушей западного и северо-восточного побережий Камчатки на разных этапах своего жизненного цикла.

    Late Pleistocene-Holocene sedimentary processes at the active margin of South-Central Chile : marine and lacustrine sediment records as archives of tectonics and climate variability (2010)
    Deutsches GeoForschungsZentrum GFZ
    In:  Scientific Technical Report
    Details
    Publication Date: 2020-02-12
    Description: In my thesis, I studied marine and lacustrine sediment cores from different depositional provinces along the south-central Chilean margin with the overall objective to identify their records of paleoclimate and paleotectonics. First of all, I investigated sedimentary sequences that were recovered within the margin-parallel trench system (cp. Figure 1.2) and hence constitute long-term recorders [...] of the sediment transport between the continent and the abyssal zone of the lower plate.

    Teleseismic tomographic images of the Central Andes at 21°S and 25.5°S : an inside look at the Altiplano and Puna plateaus (2006)
    Deutsches GeoForschungsZentrum GFZ
    In:  Scientific Technical Report STR
    Details
    Publication Date: 2021-08-21
    Description: A set of 59 seismological stations was deployed in the Central Andes region at 21°S (Chile-Bolivia) along a profile ~600 km long and were operated between 2002 and 2004. The teleseismic tomographic images (from P- and S- waves) show low-velocity anomalies that are interpreted as the effects of melting or fluids at both flanks of the Altiplano plateau. Beneath the Central Volcanic Zone (CVZ) a low-velocity anomaly is interpreted to be caused by fluids that are the origin of the volcanic material from the CVZ. A low-velocity anomaly in the upper crust is interpreted as the Altiplano Low-Velocity Zone that appears to extend as far to the east as the Eastern Cordillera. A high-velocity body between 100 km and 150 km depth is interpreted as being part of the old cold lithosphere that detached from the base of the crust. The Brazilian Shield is thought to be responsible for the strong high-velocity anomaly on the eastern side of the Central Andes. In addition, another set of 19 stations was deployed in the southern Argentine Puna along a profile ~200 km long and were run over the same period of time (2002-2004). The intention was to study the crustal thickness at 25.5°S, where delamination of the lithosphere was proposed to explain the higher elevation of the Puna plateau. Beneath the plateau a negative velocity anomaly is observed and interpreted here as being the location of fluid transfer between the deeper and shallower portions of the crust, that emanate from the Benioff zone at depths of ~200 km. This anomaly clearly divides in two branches: one to the west towards the volcanic arc (CVZ) and the other to the east where the back-arc volcanoes are located. On their way to lower depths, the fluid paths are probably influenced by the presence of nearby isotherms. The bifurcation of the ascending path could be related to the presence of the lithosphere-asthenosphere boundary (LAB) at ~100-130 km. Based on our observations, the type and form of the anomaly, it is possible to propose the presence of a return-flow type model for fluid ascent in contraposition to the assumed corner-flow model usually proposed for the Andes. The fluids that cause the seismic anomalies beneath the Puna plateau are generated at deeper levels in the asthenosphere and ascend parallel to the oceanic slab in the manner of a return-flow. In the crust and beneath the Salar de Antofalla (SA), a high-velocity block with seismic activity is interpreted as part of the old and cold Palaeozoic magmatic arc (Faja Eruptiva de la Puna Occidental). The presence of this block is may be responsible for the distribution of volcanic activity localized at both sides of this anomaly. Eastern of the SA, it is possible to recognize a zone with low-velocities beneath the Galan volcano. A sharp limit imposed by high velocities, probably related to metamorphic rocks from the Paleozoic basement (Tacuil and Luracatao ranges) can be detected on the east of the profile.

This block might be responsible for the distribution of volcanic activity localized at both sides of this anomaly. Beneath the Galan volcano and east of the SA, a zone with low-velocities can be recognized. A sharp limit towards high-velocities can be observed on the east of the profile, probably related to metamorphic rocks from the Palaeozoic basement (Tacuil and Luracatao ranges).
