First Calibrated Methane Bubble Wintertime Observations in the Siberian Arctic Seas: Selected Results from the Fast Ice

Autor: Denis Chernykh, Natalia Shakhova, Vladimir Yusupov, Elena Gershelis, Boris Morgunov, Igor Semiletov

Publikováno v: Geosciences, Vol 13, Iss 8, p 228 (2023)

This paper presents the results of an acoustic survey carried out from the fast ice in the shallow waters of the East Siberian Arctic Shelf (ESAS) using a single beam echosounder. The aim of this paper is to demonstrate an improved approach to study

Time-Domain Electromagnetics for Subsea Permafrost Mapping in the Arctic: The Synthetic Response Analyses and Uncertainty Estimates from Numerical Modelling Data

Autor: Dmitry A. Alekseev, Andrey V. Koshurnikov, Alexey Yu. Gunar, Ermolay I. Balikhin, Igor P. Semiletov, Natalia E. Shakhova, Nikolay A. Palshin, Leopold I. Lobkovsky

Publikováno v: Geosciences, Vol 13, Iss 5, p 144 (2023)

Subsea permafrost stability is the key to whether pre-performed methane sequestered in hydrate deposits escapes to the overlying strata. By making use of the 1D numerical modeling and field data, we analyze the capabilities of the time-domain (transi

Hydrocarbon Gases in Seafloor Sediments of the Edge Shelf Zone of the East Siberian Sea and Adjacent Part of the Arctic Ocean

Autor: Andrey Yatsuk, Alexander Gresov, Glen Tritch Snyder

Publikováno v: Frontiers in Earth Science, Vol 10 (2022)

The continental margins of the East Siberian Sea and Arctic Ocean are among the Earth’s most inaccessible marine environments for hydrocarbon research due to the almost year-round presence of ice cover. Despite this, limited preliminary assessments

Echo Sounding for Remote Estimation of Seabed Temperatures on the Arctic Shelf

Autor: Vladimir Yusupov, Aleksandr Salomatin, Natalia Shakhova, Denis Chernykh, Anna Domaniuk, Igor Semiletov

Publikováno v: Geosciences, Vol 12, Iss 9, p 315 (2022)

The East Siberian Arctic Shelf (ESAS) is a key area of CH4 venting in the Arctic Ocean. The ESAS region stores more than 80% of the world’s predicted subsea permafrost and associated permafrost-related gas hydrates. Gas emissions from subsea permaf

EVIDENCE OF ATMOSPHERIC RESPONSE TO METHANE EMISSIONS FROM THE EAST SIBERIAN ARCTIC SHELF

Autor: Natalia Pankratova, Andrey Skorokhod, Igor Belikov, Nikolai Elansky, Vadim Rakitin, Yury Shtabkin, Elena Berezina

Publikováno v: Geography, Environment, Sustainability, Vol 11, Iss 1, Pp 85-92 (2018)

Average atmospheric methane concentration (CH4) in the Arctic is generally higher than in other regions of the globe. Due to the lack of observations in the Arctic there is a deficiency of robust information about sources of the methane emissions. Me

Sonar Estimation of Methane Bubble Flux from Thawing Subsea Permafrost: A Case Study from the Laptev Sea Shelf

Autor: Denis Chernykh, Vladimir Yusupov, Aleksandr Salomatin, Denis Kosmach, Natalia Shakhova, Elena Gershelis, Anton Konstantinov, Andrey Grinko, Evgeny Chuvilin, Oleg Dudarev, Andrey Koshurnikov, Igor Semiletov

Publikováno v: Geosciences, Vol 10, Iss 10, p 411 (2020)

Seeps found offshore in the East Siberian Arctic Shelf may mark zones of degrading subsea permafrost and related destabilization of gas hydrates. Sonar surveys provide an effective tool for mapping seabed methane fluxes and monitoring subsea Arctic p

Lithological features of surface sediment and their influence on organic m atter distribution across the East-Siberian Arctic shelf

Autor: Elena Vladimirovna Panova, Aleksey Sergeevich Ruban, Oleg Viktorovich Dudarev, Tommaso Tesi, Lisa Brooder, Orjan Gustafsson, Andrey Alekseevich Grinko, Nataljya Evgenjevna Shakhova, Ivan Vasilyevich Goncharov, Aleksey Karpovich Mazurov, Igor Petrovich Semiletov

Publikováno v: Известия Томского политехнического университета: Инжиниринг георесурсов, Vol 328, Iss 8 (2017)

The Arctic is undergoing rapid climate change, which affects the global and regional carbon cycles. The East Siberian Arctic shelf, that is believed to store huge amounts of organic carbon in different pools, has been the subject of growing scientifi
