Carbon Dioxide and Methane Release Following Abrupt Thaw of Pleistocene Permafrost Deposits in Arctic Siberia
; ; ; ; ; ; ; ; ; (Journal of Geophysical Research: Biogeosciences, 2021-11-01)
The decomposition of thawing permafrost organic matter (OM) to the greenhouse gases (GHG) carbon dioxide (CO2) and methane forms a positive feedback to global climate change. Data on in situ GHG fluxes from thawing permafrost ... -
Carbon in tundra soils in the Lake Labaz region of arctic Siberia
(Blackwell Publishing2007-03-29)Large amounts of carbon are stored in permafrost-affected soils of the Arctic tundra. The quantity, distribution and composition of this carbon are important, because much of the carbon is likely to be released as a result ... -
Carbon release and transformation from coastal peat deposits controlled by submarine groundwater discharge: a column experiment study
; ; ; ; ; ; ; (Limnology and Oceanography, 2020)
Abstract Although the majority of coastal sediments consist of sandy material, in some areas marine ingression caused the submergence of terrestrial carbon-rich peat soils. This affects the coastal carbon balance, as peat ... -
Carbon sequestration in hedgerow biomass and soil in the temperate climate zone
; ; (Regional Environmental Change, 2021-07-10)
Hedgerows are a traditional form of agroforestry in the temperate climate zone. The establishment of hedgerows may be a promising strategy to promote carbon (C) sinks for climate change mitigation. We therefore conducted ... -

Carbonate platform drowning caught in the act: The sedimentology of Saya de Malha Bank (Indian Ocean)
; ; ; ; ; ; ; ; ; (Sedimentology, 2022-09-21)
Mesophotic reefs, hardgrounds and current‐controlled pelagic to hemipelagic carbonates are facies marking carbonate platform drowning successions, irrespective of the factors controlling this evolution. A modern analogue ... -
Carbonates from the ancient world's longest aqueduct: A testament of Byzantine water management
; ; ; ; Mertz‐Kraus, Regina (Geoarchaeology, 2021-05-06)
The fourth‐ and fifth‐century aqueduct system of Constantinople is, at 426 km, the longest water supply line of the ancient world. Carbonate deposits in the aqueduct system provide an archive of both archaeological ... -
Carpathian Basin and the development of the Hungarian landscape theory until 1948
(Discussion Papers / Centre for Regional Studies of Hungarian Academy of Science; 44)The emphasis between theoretical, global and regional geography, proportion from research to publication has changed several times during the history of Hungarian geography. Certain scholars of Hungarian geography ... -
Casting new light on the chronology of the loess/paleosol sequences in Lower Austria
Terhorst, Birgit; Thiel, Christine; Peticzka, Robert;; Frechen, Manfred; Fladerer, A., Florian; Roetzel, Reinhard; Neugebauer-Maresch, Christine (E&G – Quaternary Science Journal; Vol.60, No. 2-3)
Der vorliegende Artikel gibt einen Überblick über neu datierte Abschnitte in bekannten Löss/Paläoboden-Sequenzen Niederösterreichs. Die Ergebnisse der Datierungen im Profil Joching deuten darauf hin, dass es im letzten ... -
Catastrophic cooling in solar coronal loops - thermal instability as a road to complex evolution
(Univ. Freiburg (Breisgau), 2005)
Satellite observations with high spatial and temporal resolution have revealed the highly dynamic nature of the solar corona and enabled us to study physical processes in the outer atmosphere of our mother star in great ... -
Cation distribution in Cu2ZnSnSe4, Cu2FeSnS4 and Cu2ZnSiSe4 by multiple‐edge anomalous diffraction
(Acta Crystallographica Section B, 2020-12-07)Multiple‐Edge Anomalous Diffraction (MEAD) has been applied to various quaternary sulfosalts belonging to the adamantine compound family in order to validate the distribution of copper, zinc and iron cations in the structure. ... -
Catshark egg capsules from a Late Eocene deep-water methane-seep deposit in western Washington State, USA
Kiel, Steffen;; Simon, Klaus (Acta Palaeontologica Polonica, 2011-11-08)
Fossil catshark egg capsules, Scyliorhinotheca goederti gen. et sp. nov., are reported from a Late Eocene deep−water methane−seep calcareous deposit in western Washington State, USA. The capsules are preserved three−dimensionally ... -
Causes and consequences of long-term groundwater overabstraction in Jordan
; ; ; ; ; ; (Hydrogeology Journal, 2021-09-25)
In 2017, a comprehensive review of groundwater resources in Jordan was carried out for the first time since 1995. The change in groundwater levels between 1995 and 2017 was found to be dramatic: large declines have been ... -
Causes for Atlantic Freshwater Content Variability in the GECCO3 Ocean Synthesis
; ; (Journal of Geophysical Research: Oceans, 2022-12-28)
Regional freshwater content (FWC) changes are studied over the period 1961–2018 using the GECCO3 ocean synthesis. In four dynamically distinct regions of the Atlantic, the study identifies causes for FWC variability with ... -
Cave paleozoology in the Judean Desert: assembling records of Holocene wild mammal communities
; ; ; ; ; ; (Journal of Quaternary Science, 2021-12-24)
Long temporal records of Holocene wild mammal communities are essential to examine the role of human impacts and climatic fluctuations in the configuration of modern ecosystems. We show that such records can be assembled ... -
CAYMAN: Characterizing the crust using 2D & 3D seismic tomographic methods.
; ; ; Meléndez, Adrià; Peirce, Christine; Van Avendonk, Harm (2021)
About 25% of the Earth’s mid-ocean ridges spread at ultraslow rates of less than 20 mm/yr. However, most of these ultraslow spreading ridges are located in geographically remote areas, which hamper investigation. Consequently, ... -
Cenozoic Exhumation and Deformation of the Intermontane Pastos Chicos Basin in the Southern Central Andes: Implications for the Tectonic Evolution of the Andean Plateau (Puna) and the Eastern Cordillera Between 23° and 24°S, NW Argentina
; ; ; ; ; ; ; (Tectonics, 2023-02-03)
The Andean Plateau of north‐western Argentina (Puna) at a mean elevation of ca. 4.2 km constitutes the southern continuation of the Altiplano; it is a compressional basin‐and‐range province comprising fault‐bounded, ... -
Cenozoic Methane-Seep Faunas of the Caribbean Region.
(PloS one, 2015)We report new examples of Cenozoic cold-seep communities from Colombia, Cuba, the Dominican Republic, Trinidad, and Venezuela, and attempt to improve the stratigraphic dating of Cenozoic Caribbean seep communities using ... -
