Combining “Deep Learning” and Physically Constrained Neural Networks to Derive Complex Glaciological Change Processes from Modern High-Resolution Satellite Imagery: Application of the GEOCLASS-Image System to Create VarioCNN for Glacier Surges

Remote Sensing
The objectives of this paper are to investigate the trade-offs between a physically constrained neural network and a deep, convolutional neural network and to design a combined ML approach (“VarioCNN”).

Control of Ocean Temperature on Jakobshavn Isbræ's Present and Future Mass Loss

Geophysical Research Letters, 2018
Large uncertainties in model parameterizations and input data sets make projections of future sea level rise contributions of outlet glaciers challenging.

Reconstructing the late Pleistocene glacial history of the Cairngorm Mountains, Scotland, using paired cosmogenic 10Be and 14C

Journal of Quaternary Science, EarlyView.
ABSTRACT Chronologic and geomorphic evidence of past glaciations is largely recorded in areas at relatively low elevation and/or landscapes defined by high glacial erosion. As a result, data from areas that did not experience significant glacial erosion and the highest elevation locations are lacking from reconstructions of past ice masses.

Grounding Line Remote Operated Vehicle (GROV) Survey of the Ice Shelf Cavity of Petermann Glacier, Greenland

Geophysical Research Letters
The melting of glaciers by ocean waters along the ice sheet periphery is a major physical process driving glacier evolution in a changing climate. Using a fiber‐optic‐tethered Grounding line Remote Operated Vehicle, we explore the ice shelf cavity of ...

UAV and GPR Data Integration in Glacier Geometry Reconstruction: A Case Study from Irenebreen, Svalbard

Remote Sensing, 2022
Although measurements of thickness and internal structure of glaciers are substantial for the understanding of their evolution and response to climate change, detailed data about polythermal glaciers, are scarce.

Stratigraphy and geomorphology of Des‐Cubierta Cave (Pinilla del Valle, Madrid, Spain): Geological insights into a Neanderthal symbolic accumulation of large crania

Journal of Quaternary Science, EarlyView.
ABSTRACT Des‐Cubierta Cave, part of the Calvero de la Higuera complex, is situated in the intramountainous upper valley of the Lozoya River within the Guadarrama Range. The cave's geological, palaeontological, and archaeological record reveals a complex history of sedimentary and anthropogenic processes spanning hundreds of thousands of years ...

Exploring Ice Cave Biodiversity in Northeastern Italy

Diversity
The ice stored in caves is a widespread yet neglected cryospheric component. The cold-adapted biodiversity of ice caves has received very little attention from research, despite the potential abundance of endemic troglobiotic and cryophilic species and ...

Challenges in dating blanket peat and implications for understanding its initiation in Ireland

Journal of Quaternary Science, EarlyView.
ABSTRACT Blanket peat is widespread in maritime extra‐tropical environments. Prehistoric land‐use activity was traditionally invoked as the stimulus of blanket peat initiation in the British Isles, but recently, climate has been viewed as the driver of peat formation.

Multi‐million‐year evolution of the Greenland Ice Sheet in Inglefield Land, North Greenland

Journal of Quaternary Science, EarlyView.
ABSTRACT Information on past sensitivity of the Greenland Ice Sheet to climate change is of importance for optimizing models simulating the future evolution of ice mass loss. While the ice‐sheet change during the Lateglacial and Holocene is relatively well constrained, the long‐term (multi‐million‐year) evolution of the Greenland Ice Sheet remains ...
