Journal ArticleDOI
Extensive release of methane from Arctic seabed west of Svalbard during summer 2014 does not influence the atmosphere

Lund Myhre,Bénédicte Ferré,Stephen Matthew Platt,Anna Silyakova,Ove Hermansen,Grant Allen,Ignacio Pisso,Norbert Schmidbauer,Andreas Stohl,Joseph Pitt,Pär Jansson,Jens Greinert,Jens Greinert,Jens Greinert,Carl J. Percival,A. M. Fjaeraa,Sebastian O'Shea,Martin Gallagher,M. Le Breton,Keith Bower,Stephane Bauguitte,S. B. Dalsøren,Sunil Vadakkepuliyambatta,Rebecca Fisher,Euan G. Nisbet,David Lowry,Gunnar Myhre,John A. Pyle,Michelle Cain,Jürgen Mienert +29 more
TL;DR: In this article, the authors find that summer methane (CH4) release from seabed sediments west of Svalbard substantially increases CH4 concentrations in the ocean but has limited influence on the atmospheric CH4 levels.
Journal ArticleDOI

Giuliana Panieri,Stefan Bünz,Daniel J. Fornari,Javier Escartín,Pavel Serov,Pär Jansson,Marta E Torres,Joel E. Johnson,Wei-Li Hong,Simone Sauer,Rafael Garcia,Nuno Gracias +11 more
TL;DR: This paper presents a meta-analyses of the EMMARM, a probabilistic approach to estimating the number of mitochondria in the response of the immune system to EMTs.
Journal ArticleDOI
Reduced methane seepage from Arctic sediments during cold bottom-water conditions
Bénédicte Ferré,Pär Jansson,Manuel Moser,Pavel Serov,Alexey Portnov,Carolyn Graves,Carolyn Graves,Giuliana Panieri,Friederike Gründger,Christian Berndt,Moritz F. Lehmann,Helge Niemann +11 more
TL;DR: In this paper, the authors compare the activity of cold seeps along the gas hydrate stability limit offshore Svalbard during cold (May 2016) and warm (August 2012) seasons.
Journal ArticleDOI
Methane at Svalbard and over the European Arctic Ocean
Stephen Matthew Platt,Sabine Eckhardt,Bénédicte Ferré,Rebecca Fisher,Ove Hermansen,Pär Jansson,David Lowry,Euan G. Nisbet,Ignacio Pisso,Norbert Schmidbauer,Anna Silyakova,Andreas Stohl,Tove Marit Svendby,Sunil Vadakkepuliyambatta,Jürgen Mienert,Cathrine Lund Myhre +15 more
TL;DR: This article investigated areas over the European Arctic Ocean to identify possible hotspot regions emitting methane from the ocean to the atmosphere, and used state-of-the-art FLEXPART combined with updated emission inventories to identify high-latitude CH4 sources.
Journal ArticleDOI
Physical controls of dynamics of methane venting from a shallow seep area west of Svalbard
Anna Silyakova,Pär Jansson,Pavel Serov,Bénédicte Ferré,Alexey Pavlov,Tore Hattermann,Carolyn Graves,Carolyn Graves,Stephen Matthew Platt,Cathrine Lund Myhre,Friederike Gründger,Helge Niemann +11 more
TL;DR: In this article, the authors investigate methane seepage on the shallow shelf west of Svalbard during three consecutive years, using discrete sampling of the water column, echosounder-based gas flux estimates, water mass properties, and numerical dispersion modelling.
