The relationship between precipitation and its spatial pattern in the trades observed during EUREC4A
(Quarterly Journal of the Royal Meteorological Society, 2022-05-16)Trade wind convection organises into a rich spectrum of spatial patterns, often in conjunction with precipitation development. Which role spatial organisation plays for precipitation and vice versa is not well understood. ... -
Asteroid 2008 TC3, not a polymict ureilitic but a polymict C1 chondrite parent body? Survey of 249 Almahata Sitta fragments
(Meteoritics & Planetary Science, 2022-05-14)On October 7, 2008, the asteroid 2008 TC3 exploded as it entered the Earth’s atmosphere, producing significant dust (in the atmosphere) and delivering thousands of stones in a strewn field in Sudan, collectively known as ... -
The Two‐Energies Turbulence Scheme Coupled to the Assumed PDF Method
(Journal of Advances in Modeling Earth Systems, 2022-05-14)An update of the two‐energy turbulence scheme is presented, the 2TE + APDF scheme. The original version of the two‐energy scheme is able to successfully model shallow convection without the need of an additional parameterization ... -
Palaeoecological signals for Mesolithic land use in a Central European landscape?
(Journal of Quaternary Science, 2022-05-12)During the Early Holocene, climate was the major factor causing fires, but whether during the Mesolithic (~11.5–7.4 cal ka BP) people co‐shaped their environment by means of fire remains of debate. Few studies have tackled ... -
Crustal Structure of the Indochina Peninsula From Ambient Noise Tomography
(Journal of Geophysical Research: Solid Earth, 2022-05-10)The collision between the Indian and Eurasian plates promotes the southeastward extrusion of the Indochina Peninsula while the internal dynamics of its crustal deformation remain enigmatic. Here, we make use of seismic ... -
Role of Poroelasticity During the Early Postseismic Deformation of the 2010 Maule Megathrust Earthquake
(Geophysical Research Letters, 2022-05-09)Megathrust earthquakes impose changes of differential stress and pore pressure in the lithosphere‐asthenosphere system that are transiently relaxed during the postseismic period primarily due to afterslip, viscoelastic and ... -
A New Population of Ultra‐Relativistic Electrons in the Outer Radiation Zone
(Journal of Geophysical Research: Space Physics, 2022-05-09)Van Allen Probes measurements revealed the presence of the most unusual structures in the ultra‐relativistic radiation belts. Detailed modeling, analysis of pitch angle distributions, analysis of the difference between ... -
Greenhouse Gas Mitigation Potential of Alternate Wetting and Drying for Rice Production at National Scale—A Modeling Case Study for the Philippines
(Journal of Geophysical Research: Biogeosciences, 2022-05-09)Worldwide, rice production contributes about 10% of total greenhouse gas (GHG) emissions from the agricultural sector, mainly due to CH4 emissions from continuously flooded fields. Alternate Wetting and Drying (AWD) is a ... -
Clay fraction properties and grassland management imprint on soil organic matter composition and stability at molecular level
(Soil Use and Management, 2022-05-07)The dynamics of soil carbon in grassland are partly determined by soil organic matter (SOM) composition. However, it remains unclear which role grassland management plays in the interplay between SOM composition and carbon ... -
Late Quaternary paleoenvironmental reconstructions from sediments of Lake Emanda (Verkhoyansk Mountains, East Siberia)
(Journal of Quaternary Science, 2022-05-06)Continuous pollen and chironomid records from Lake Emanda (65°17′N, 135°45′E) provide new insights into the Late Quaternary environmental history of the Yana Highlands (Yakutia). Larch forest with shrubs (alders, pines, ... -
The detection of bacterial exometabolites in marine dissolved organic matter through ultrahigh‐resolution mass spectrometry
(Limnology and Oceanography: Methods, 2022-05-05)Bacteria play a key role in sustaining the chemodiversity of marine dissolved organic matter (DOM), yet there is limited direct evidence of a major contribution of bacterial exometabolites to the DOM pool. This study tests ... -
Microbially promoted calcite precipitation in the pelagic redoxcline: Elucidating the formation of the turbid layer
(Geobiology, 2022-05-05)Large bell‐shaped calcite formations called “Hells Bells” were discovered underwater in the stratified cenote El Zapote on the Yucatán Peninsula, Mexico. Together with these extraordinary speleothems, divers found a white, ... -
Melting Behavior of Rimed and Unrimed Snowflakes Investigated With Statistics of Triple‐Frequency Doppler Radar Observations
(Journal of Geophysical Research: Atmospheres, 2022-05-04)Comparing the reflectivity flux at the top and bottom of the melting layer (ML) reveals the overall effect of the microphysical processes occurring within the ML on the particle population. If melting is the only process ... -
Temporal evolution of headwall erosion rates derived from cosmogenic nuclide concentrations in the medial moraines of Glacier d'Otemma, Switzerland
(Earth Surface Processes and Landforms, 2022-05-03)Climate change affects the stability and erosion of high‐alpine rock walls above glaciers (headwalls) that deliver debris to glacier surfaces. Since supraglacial debris in the ablation zone alters the melt behaviour of the ... -
Strain Signals Governed by Frictional‐Elastoplastic Interaction of the Upper Plate and Shallow Subduction Megathrust Interface Over Seismic Cycles
(Tectonics, 2022-05-03)The behavior of the shallow portion of the subduction zone, which generates the largest earthquakes and devastating tsunamis, is still insufficiently constrained. Monitoring only a fraction of a single megathrust earthquake ... -
Nonmarine Ostracoda as proxies in (geo‐)archaeology — A review
(Geoarchaeology, 2022-05-03)Ostracods as bioindicators are extremely useful for reconstructing palaeoenvironment and palaeoclimate and can also indicate the provenance of sediments and materials, for example, in studies on ancient commercial networks. ... -
Alternating Emission Features in Io's Footprint Tail: Magnetohydrodynamical Simulations of Possible Causes
(Journal of Geophysical Research: Space Physics, 2022-04-28)Io's movement relative to the plasma in Jupiter's magnetosphere creates Alfvén waves propagating along the magnetic field lines which are partially reflected along their path. These waves are the root cause for auroral ... -
