    Chlorine isotope ratios record magmatic brine assimilation during rhyolite genesis 
    Ranta, Eemu Johannes; Halldórsson, Sæmundur Ari; Barnes, J. D.; Jónasson, Kristján; Stefánsson, Andri (2021-01-13)
    Magmatic volatile phases within crustal silicic magma domains influence key volcanic processes such as the build up to eruptions and formation of magmatic-hydrothermal ore deposits. However, the extent and nature of fluid-melt interaction in such ...

    DO RADIOCARBON AGES of PLANT WAX BIOMARKERS AGREE with 14C-TOC/OSL-BASED AGE MODELS in AN ARID HIGH-ALTITUDE LAKE SYSTEM? 
    Aichner, Bernhard; Gierga, Merle; Stolz, Alexander; Mȩtrak, Monika; Wilk, Mateusz; Suska-Malawska, Małgorzata; Mischke, Steffen; Sachse, Dirk; Rajabov, Ilhomjon; Rajabov, Nasimjon; Rethemeyer, Janet (2021-09-23)
    To elucidate the dynamics of terrestrial leaf waxes in a high-altitude lake system, we performed compound-specific radiocarbon analysis (CSRA) of long-chain n-alkanes in two sediment core sections from Lake Karakul (Pamirs, Tajikistan) and in surface ...

    Response of biological productivity to North Atlantic marine front migration during the Holocene 
    Harning, David John; Jennings, Anne E.; Köseoglu, Denizcan; Belt, Simon T.; Geirsdóttir, Áslaug; Sepúlveda, Julio (2021-02-08)
    Marine fronts delineate the boundary between distinct water masses and, through the advection of nutrients, are important facilitators of regional productivity and biodiversity. As the modern climate continues to change, the migration of frontal zones ...

    Temporal Seismic Velocity Changes During the 2020 Rapid Inflation at Mt. Þorbjörn-Svartsengi, Iceland, Using Seismic Ambient Noise 
    Cubuk-Sabuncu, Yesim; Jónsdóttir, Kristín; Caudron, Corentin; Lecocq, Thomas; Parks, Michelle Maree; Geirsson, Halldór; Mordret, Aurélien (2021-06-01)
    Repeated periods of inflation-deflation in the vicinity of Mt. Þorbjörn-Svartsengi, SW-Iceland, were detected in January–July, 2020. We used seismic ambient noise and interferometry to characterize temporal variations of seismic velocities (dv/v, %). ...
