چکیده
This report presents a brief description of the expeditionary work performed by staff Institute Volcanology and Seismology, Far Eastern Branch Russian Academy Sciences as part research topic Science Foundation project on Kuril Islands in summer 2022. In order to study chemical erosion volcanic islands assess hydrothermal removal magmatic volatiles, addition works carried out 2020 2021, hydrological hydrochemical studies were comducted rivers draining slopes ridges Paramushir, Onekotan Shiashkotan islands. For first time, with help quadrocopter, sampling endorheic Lake Koltsevoe, which occupies caldera Tao-Rusyr volcano (Onekotan Island), was out. A detailed testing thermal fields active volcanoes Sinarka Kuntomintar (Shiashkotan Island) performed, number regime observations Upper Yuryevsk springs (Paramushir replenished. construct orthophotomaps determine boundaries anomalies, aerial infrared surveys at main sites parallel geochemical sampling. large water gas samples taken for further analytical during expedition collection sediments

The 2006–2007 Kuril Islands great earthquake sequence
[1] The southwestern half of a 500 km long seismic gap in the central Kuril Island arc subduction zone experienced two great earthquakes with extensive preshock and aftershock sequences in late 2006 to early 2007. The nature of seismic coupling in the gap had been uncertain due to the limited historical record of prior large events and the presence of distinctive upper plate, trench and outer r...
متن کاملRescuing biogeographic legacy data: The "Thor" Expedition, a historical oceanographic expedition to the Mediterranean Sea
BACKGROUND This article describes the digitization of a series of historical datasets based οn the reports of the 1908-1910 Danish Oceanographical Expeditions to the Mediterranean and adjacent seas. All station and sampling metadata as well as biodiversity data regarding calcareous rhodophytes, pelagic polychaetes, and fish (families Engraulidae and Clupeidae) obtained during these expeditions ...
متن کاملGeographic Distribution of Ammonia-Oxidizing Archaea along the Kuril Islands in the Western Subarctic Pacific
Community composition and abundance of ammonia-oxidizing archaea (AOA) in the ocean were affected by different physicochemical conditions, but their responses to physical barriers (such as a chain of islands) were largely unknown. In our study, geographic distribution of the AOA from the surface photic zone to the deep bathypelagic waters in the western subarctic Pacific adjacent to the Kuril I...
متن کاملSequencing at sea: challenges and experiences in Ion Torrent PGM sequencing during the 2013 Southern Line Islands Research Expedition
Genomics and metagenomics have revolutionized our understanding of marine microbial ecology and the importance of microbes in global geochemical cycles. However, the process of DNA sequencing has always been an abstract extension of the research expedition, completed once the samples were returned to the laboratory. During the 2013 Southern Line Islands Research Expedition, we started the first...
