Enhancing Recharge Beneath Low‐Permeability Landscapes with Small‐Diameter Drywells: Token Creek, WI

Groundwater, EarlyView.
Shallow, small‐diameter drywells provide enhanced recharge in rural landscapes, bypassing the low infiltration rates caused by low permeability surficial soils and high ET rates. One year of monitoring data show several recharge events and overall high water quality.

The XenCart Protocol: A method for Alcian blue labeling and quantitative analysis of craniofacial cartilage in Xenopus

Journal of Anatomy, EarlyView.
The XenCart Protocol provides a reproducible way to visualize and quantify how the developing craniofacial skeleton responds to experimental perturbation. Embryos are exposed to defined conditions, craniofacial cartilage is stained with Alcian blue, imaged, and analyzed morphometrically.

Nocturnal Thermal Fracturing of a Himalayan Debris‐Covered Glacier Revealed by Ambient Seismic Noise

Geophysical Research Letters, 2018
Scientifically valuable information can be learned by listening to the tiny vibrations emanating from a glacier with seismometers. However, this approach has never been employed to better understand glaciers protected from heat by a debris mantle ...

The craters that never were: Anthropogenic origins of alleged impact structures in the Chiemgau region

Meteoritics &Planetary Science, EarlyView.
Abstract Public fascination with impact craters often drives bold speculations, but rigorous verification is critical. In southeastern Bavaria, numerous depressions have been proposed to represent impact craters associated with a catastrophic event in Celtic times (between 900 BC and 600 BC)—the so called “Chiemgau Impact.” To date, the evidence ...

Mapping of Supra-Glacial Debris Cover in the Greater Caucasus: A Semi-Automated Multi-Sensor Approach

Geosciences
Supra-glacial debris cover is important for the control of surface ice melt and glacier retreat in mountain regions. Despite the progress in techniques based on various satellite imagery, the mapping of debris-covered glacier boundaries over large ...

Variability of air temperature over a debris-covered glacier in the Nepalese Himalaya

Annals of Glaciology, 2016
Estimates of melt from debris-covered glaciers require distributed estimates of meteorological variables and air temperature in particular. Meteorological data are scarce for this environment, and spatial variability of temperature over debris is poorly ...

Contourite erosional and depositional features of the Maastrichtian chalk on Jasmund peninsula (Rügen island, NE Germany)

Sedimentology, EarlyView.
ABSTRACT Seismic‐scale features such as deeply incised submarine valleys and mounded drifts together with ichnological features indicative of discontinuous sedimentation and erosional episodes have recently been documented from the Upper Cretaceous chalk in the southern Baltic Sea area.

Quantification of dryland depositional environments across contrasting fluvio‐aeolian and fluvio‐lacustrine transects: An integrated subsurface and outcrop analogue study of the Organ Rock Formation, Utah, USA

Sedimentology, EarlyView.
ABSTRACT The standard subdivision of a distributive fluvial system (DFS) into proximal, medial and distal zones is typically based on the proportion of channel bodies and/or the degree of channel amalgamation, reflecting a downstream fining trend towards a mud‐prone terminal pinch‐out.

Perennially ice‐covered lake facies as proxies for ice cover properties and climate: Insights from Lake Joyce, Antarctica

Sedimentology, EarlyView.
ABSTRACT Process‐based depositional models for perennially ice‐covered lakes (PICLs) are important for interpreting palaeolake deposits and their connection to past climate. PICLs are only stable under specific climate states, and unlike other ice‐free or seasonally ice‐covered lakes, PICL deposits generally have bimodal grain sizes: mud introduced by ...
