Antarctic Blue Ice Areas are hydrologically active, nutrient rich and contain microbially diverse cryoconite holes
Nowak, Aga; Isaksson, Elisabeth; Sunde, Øyvind; Elvevold, Synnøve; Sandven, Håkon Johan; Moholdt, Geir; Hudson, Stephen R.; Urset, Anne; Edwards, Arwyn; Rassner, Sara M. E.; Pearce, David A.; Hamre, Børge; Hodson, Andrew (Journal article; Peer reviewed, 2024)Antarctica is the coldest, windiest and least inhabited place on Earth. One of its most enigmatic regions is scoured by katabatic winds blue ice that covers 235,000 km2 of the Antarctic fringe. Here, we demonstrate that ... -
Microbial iron reduction and greenhouse gas production in response to organic matter amendment and temperature increase of periglacial sediments, Bolterdalen, Svalbard
Kolchev, Ivaylo; Marshall, Ian P.G.; Jones, Eleanor; Yde, Jacob C.; Nørnberg, Per; Mateos-Rivera, Alejandro; Hodson, Andrew; Bak, Ebbe N.; Finster, Kai (Journal article; Peer reviewed, 2022)Arctic permafrost soils store substantial reserves of organic matter (OM) from which microbial transformation contributes significantly to greenhouse gas emissions of CH4 and CO2. However, many younger sediments exposed ... -
Shallow and deep groundwater moderate methane dynamics in a high Arctic glacial catchment
Kleber, Gabrielle Emma; Magerl, Leonard; Turchyn, Alexandra V.; Redeker, Kelly; Thiele, Stefan; Liira, Martin; Herodes, Koit; Øvreas, Lise; Hodson, Andrew (Journal article; Peer reviewed, 2024)Glacial groundwater can mobilize deep-seated methane from beneath glaciers and permafrost in the Arctic, leading to atmospheric emissions of this greenhouse gas. We present a temporal, hydro-chemical dataset of methane-rich ... -
Targeting methanotrophs and isolation of a novel psychrophilic Methylobacter species from a terrestrial Arctic alkaline methane seep in Lagoon Pingo, Central Spitsbergen (78° N)
Patil, Shalaka Kiran; Islam, Tajul; Tveit, Alexander Tøsdal; Hodson, Andrew; Øvreås, Lise (Journal article; Peer reviewed, 2024)The microbial diversity associated with terrestrial groundwater seepage through permafrost soils is tightly coupled to the geochemistry of these fluids. Terrestrial alkaline methane seeps from Lagoon Pingo, Central Spitsbergen ...
