Anti‐Phased Miocene Ice Volume and CO2 Changes by Transient Antarctic Ice Sheet Variability
; ; (Paleoceanography and Paleoclimatology, 2020-11-24)
Geological evidence indicates large continental‐scale Antarctic ice volume variations during the early and mid‐Miocene. On million‐year timescales, these variations can largely be explained by equilibrium Antarctic ice ... -
Assessing the Potential for Mobilization of Old Soil Carbon After Permafrost Thaw: A Synthesis of 14C Measurements From the Northern Permafrost Region
Estop‐Aragonés, Cristian;; ; ; ; ; Egan, Jocelyn E.; ; Garnett, Mark H.; Hartley, Iain P.; ; ; Natali, Susan M.; O'Donnell, Jonathan A.; ; Tanentzap, Andrew J.; ; ; Turetsky, Merritt; Anthony, Katey Walter (Global Biogeochemical Cycles, 2020-09-14)
The magnitude of future emissions of greenhouse gases from the northern permafrost region depends crucially on the mineralization of soil organic carbon (SOC) that has accumulated over millennia in these perennially frozen ... -
BEST PRACTICE GUIDELINE Measurement of carbon dioxide, methane and nitrous oxide fluxes between soil-vegetation-systems and the atmosphere using non-steady state chambers - Version 1
; ; ; ; ; ; ; ; ; ; ; (Arbeitsgruppe Bodengase, Deutsche Bodenkundliche GesellschaftGöttingen, 2022)
This Best Practice Guideline was been initiated by the Working Group Soil Gases (AG Bodengase) of the German Soil Science Society (Deutsche Bodenkundliche Gesellschaft). Our intention was to collect and aggregate the ... -
Dynamics of Greenhouse Gases (CH4 and CO2) in Meromictic Lake Burgsee, Germany
;; (Journal of Geophysical Research: Biogeosciences, 2022-08-19)
Extraordinary amounts of greenhouse gases can be stored within the monimolimnion of meromictic lakes, that is, in the water body which is excluded from mixing events. Lake Burgsee (Thuringia, Germany) is a shallow (depth ... -
Economic aspirations connected to innovations in carbon capture and utilization value chains
(Journal of Industrial Ecology, 2020-04-07)
International authorities are increasingly recognizing that utilizing the carbon dioxide (CO2) emissions from various industries can assist strategies for mitigating climate change. In developing novel carbon capture and ... -
Effects of Reversal of Water Flow in an Arctic Floodplain River on Fluvial Emissions of CO2 and CH4
; ; ; ; ; ; ; ; ; ; (Journal of Geophysical Research: Biogeosciences, 2022-01-04)
When organic matter from thawed permafrost is released, the sources and sinks of greenhouse gases (GHGs), like carbon dioxide (CO2) and methane (CH4) in Arctic rivers will be influenced in the future. However, the temporal ... -
Long‐term intercomparison of two pCO2 instruments based on ship‐of‐opportunity measurements in a dynamic shelf sea environment
; ; ; Triest, Jack; Petersen, Wilhelm (Limnology and Oceanography: Methods, 2020-12-28)
The partial pressure of carbon dioxide (pCO2) in surface seawater is an important biogeochemical variable because, together with the pCO2 in the atmosphere, it determines the direction of air–sea carbon dioxide exchange. ... -
Pinpointing Deep Geothermal Upflow in Zones of Complex Tectono-Volcanic Degassing: New Insights from Aluto Volcano, Main Ethiopian Rift
; Hutchison, W.; Driba, D.L.; ; Gizaw, B. (Geochemistry, Geophysics, Geosystems, 2019)
Active rifts release large amounts of gases from deep sources to the atmosphere by advection and diffusion processes along permeable fracture zones. The objective of this study is to develop geothermal exploration concepts ...
