Thickness estimation of supraglacial debris above ice cliff exposures using a high-resolution digital surface model derived from terrestrial photography

Journal of Glaciology, 2017
The thickness of supraglacial debris cover controls how it impacts the ablation rate of underlying glacier ice, yet this quantity remains challenging to measure, particularly at glacier scales.

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.

Surface facies analysis of the Gangotri and neighbouring glaciers, central Himalaya

Science of Remote Sensing
Glaciers are primarily monitored using medium-to-high resolution satellite data, undermining the potential of coarse-resolution data. In pursuance of this, high resolution 10 m super-resolved glacier maps derived from 56 m coarse-resolution AWiFS data ...

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 ...

Ridges on martian debris-covered glaciers : deconvolving structural and climate processes [PDF]

, 2017
Debris-covered glaciers on Earth and Mars often exhibit surface ridges transverse to the flow direction of the glacier. The formation mechanism of these ridges is not well established, but some evidence from terrestrial analogues supports the idea that ...

A low-cost and open-source approach for supraglacial debris thickness mapping using UAV-based infrared thermography [PDF]

The Cryosphere
Debris-covered glaciers exist in many mountain ranges and play an important role in the regional water cycle. However, modelling the surface mass balance, runoff contribution and future evolution of debris-covered glaciers is fraught with uncertainty as ...

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.
