Amplified Arctic Surface Warming and Sea Ice Loss Due to Phytoplankton and Colored Dissolved Material
(
- Geophysical Research Letters
, 2020-11-02)
Optically active water constituents attenuate solar radiation and hence affect the vertical distribution of energy in the upper ocean. To understand their implications, we operate an ocean biogeochemical model coupled to ...
Why productive lakes are larger mercury sedimentary sinks than oligotrophic brown water lakes
(
- Limnology and Oceanography
, 2020-12-25)
Mercury accumulation in lake sediments is a widespread environmental problem due to the biomagnification of Hg in the aquatic food chain. Soil Hg concentrations, catchment vegetation, erosion, and lake productivity are ...
Determining paracrystallinity in mixed‐tacticity polyhydroxybutyrates
(
- Journal of Applied Crystallography
, 2021-01-22)
Recently, the authors reported on the development of crystallinity in mixed‐tacticity polyhydroxybutyrates. Comparable values reported in the literature vary depending on the manner of determination, the discrepancies being ...
Effect‐Based Trigger Values for Mixtures of Chemicals in Surface Water Detected with In Vitro Bioassays
(
- Environmental Toxicology and Chemistry
, 2021-01-13)
Effect‐based trigger (EBT) values for in vitro bioassays are important for surface water quality monitoring because they define the threshold between acceptable and poor water quality. They have been derived for highly ...
Ursprung und Entwicklung des Altkristallins Ostkretas, Griechenland
(Univ. Frankfurt (Main), 2006)
In Ostkreta tritt innerhalb der Phyllit-Quarzit-Serie ein in vier Einheiten untergliederbares präalpidisches Altkristallin auf. Das basale Kalavros-Kristallin (KCC) wurde während der permischen (Monazitalter) Barrow-Metamorphose ...
Measured and Simulated Carbon Dynamics in Midwestern U.S. Corn‐Soybean Rotations
(
- Global Biogeochemical Cycles
, 2020-12-29)
Corn (Zea mays L.) and soybean (Glycine max [L.] Merr.) production dominate Midwestern U.S. agriculture and impact the regional carbon and nitrogen cycles. Sustaining soil carbon is important for corn‐soybean production ...
Disordered sodium alkoxides from powder data: crystal structures of sodium ethoxide, propoxide, butoxide and pentoxide, and some of their solvates
(
- Acta Crystallographica Section B
, 2021-01-25)
The crystal structures of sodium ethoxide (sodium ethanolate, NaOEt), sodium n‐propoxide (sodium n‐propanolate, NaOnPr), sodium n‐butoxide (sodium n‐butanolate, NaOnBu) and sodium n‐pentoxide (sodium n‐amylate, NaOnAm) ...

Multi-component evolution, age and plate tectonic setting of high MG lamprophyric dikes and small gabbroic intrusions on Isla Margarita (Venezuela)
(Univ. Bochum, 1997)
Die Isla Margarita (Venezuela) am Südrand der Karibischen Platte besteht aus einem heterogenen Krustenkomplex aus Peridotiten, Metamorphiten, diversen Magmatiten und sedimentärem Deckgebirge. Die jüngsten Magmatite sind ...
Zircon and Melt Extraction From a Long‐Lived and Vertically Extensive Magma System Underneath Ilopango Caldera (El Salvador)
(
- Geochemistry, Geophysics, Geosystems
, 2021-05-12)
The Tierra Blanca (TB) eruptive suite comprises the last four major eruptions of Ilopango caldera in El Salvador (≤45 ka), including the youngest Tierra Blanca Joven eruption (TBJ; ∼106 km3): the most voluminous event ...
