Dynamics of particle transport from soils to the sea [PDF]
Royal Society Open ScienceIn this study, we explore the fate of soils, from their erosion into rivers to their final deposition as either continental or marine deposits. We focus on the continental United States and compare the chemistries of river suspended and bottom sediment ...

Assessing the preservation potential of successive hurricane overwash deposits in Florida, USA mangroves [PDF]
Scientific ReportsGeologic records of tropical cyclones (TCs) in low-energy, back-barrier environments are established by identifying marine sediments via their allochthonous biogeochemical signal. These records have the potential to reconstruct TC intensity and frequency

Regime shift to extensive valley glaciations over High Mountain Asia during the Early-Middle Pleistocene [PDF]
Nature CommunicationsIn contrast to the well-established onset of Northern Hemisphere high-latitude glaciation at ~2.7 Ma, the timing and drivers of the intensified glaciation over High Mountain Asia (HMA) remain elusive, as glacial geologic evidence within this region is ...

Near surface sediments introduce low frequency noise into gravity models
Applied Computing and Geosciences, 2023 3D geologic modeling and mapping often relies on gravity modeling to identify key geologic structures, such as basin depth, fault offset, or fault dip.

Applied Computing and Geosciences, 2023 Previously glaciated landscapes often share similar surficial characteristics, including large areas of exposed bedrock, blankets of till deposits, and alluvium-floored valleys. These materials play significant roles in geologic and hydrologic resources,

Burial and Denudation Alter Microbial Life at the Bottom of the Hypo‐Critical Zone
Geochemistry, Geophysics, Geosystems, 2023 How subsurface microbial life changed at the bottom of the kilometers‐deep (hypo) Critical Zone in response to evolving surface conditions over geologic time is an open question.

Cost-effective mapping of benthic habitats in inland reservoirs through split-beam sonar, indicator kriging, and historical geologic data. [PDF]
PLoS ONE, 2014 Because bottom substrate composition is an important control on the temporal and spatial location of the aquatic community, accurate maps of benthic habitats of inland lakes and reservoirs provide valuable information to managers, recreational users, and

Viruses of sulfur oxidizing phototrophs encode genes for pigment, carbon, and sulfur metabolisms
Communications Earth & Environment, 2023 Viral infections modulate bacterial metabolism and ecology. Here, we investigated the hypothesis that viruses influence the ecology of purple and green sulfur bacteria in anoxic and sulfidic lakes, analogs of euxinic oceans in the geologic past.

Hydrology, 2018 Utah Lake is highly eutrophic with large phosphorous inflows and a large internal phosphorous reservoir in the sediment. There are debates over whether this phosphorous is from geologic or more recent anthropologic sources. This study characterizes total

Wirkungen des pleistozänen kaltzeitlichen Klimas, insbesondere des Bodenfrostes, in den Sedimenten des östlichen Ostfalen (Raum Hannover - Wolfsburg - Helmstedt -Bad Harzburg - Salzgitter-Bad - Hannover) - Teil 1 [PDF]
Eiszeitalter und Gegenwart, 1996 In this first part of the publication - a second part especially about ice-wedges and aeolian processes will follow in the next year - the abundant form inventory of diversified periglacial solifluction layers, of horizons of gelifraction, of ...
