Climate and Hydrogeological Controls on Water Tracks in Permafrost Landscapes
Abstract Climate change drives disturbance in hydrology and geomorphology in terrestrial polar landscapes underlain by permafrost, yet measurements of, and theories to understand, these changes are limited. Water flowing from permafrost hillslopes to channels is often modulated by water tracks, zones of enhanced soil moisture in unchannelized ...

Wetlands are vital for humanity and include some of the most productive, diverse, and service‐rich ecosystems in the world. Service provided include food production (e.g., fish, birds, and vegetables), protection from flooding and storm surge inundation, provision of clean water and climate stability, and timber resources for construction.

Ecohydrogeological processes in tropical volcanic mountains are not well understood. We combined a quantitative water balance analysis in Google Earth Engine with qualitative interpretation of the study area's geologic and geomorphic features.

Hollows on Mercury: Global Classification of Degradation States and Insight Into Hollow Evolution
Abstract Hollows are small, shallow, irregularly shaped landforms, widespread across Mercury, interpreted to have formed via loss of volatiles. Here, we present the first global analysis of hollow degradation states using a new machine learning‐derived global catalog.

On simple classes of special generic maps and round fold maps and fold maps obtained by composing projections [PDF]
Fold maps are fundamental tools in the theory of singularities of differentiable maps and its applications to geometry. They are higher dimensional variants of Morse functions. Classes of special generic maps and round fold maps are important classes of fold maps. {\it Special generic} maps are higher dimensional variants of Morse functions on homotopy

Evaluation of the impact of climate change on rainfall for potential landslide triggering in Japan
Under the scenario that future greenhouse gas emissions will continue to increase, the projection of precipitation in Japan until 2,100 suggests that intense rainfall with landslide‐triggering potential might increase and occur synchronously in two to five regions owing to more frequent and widespread occurrence of precipitation.

Deep Convolutional Neural Networks for Map-Type Classification [PDF]
Maps are an important medium that enable people to comprehensively understand the configuration of cultural activities and natural elements over different times and places. Although massive maps are available in the digital era, how to effectively and accurately access the required map remains a challenge today.

Rebalancing River Lateral Connectivity: An Interdisciplinary Focus for Research and Management
Lateral connectivity between waterscapes and adjacent landscapes is critical for river health. We review lateral connectivity across disciplines, reframing lateral connectivity for river science and management. We propose “rebalancing” bidirectional, lateral connectivity as a paradigm to employ when seeking to enhance river ecosystems and climate ...

Abstract Subsurface ice in the mid‐latitude regions is a significant water inventory on present‐day Mars, and their volume and distribution are thought to have varied due to the orbitally induced paleoclimatic changes. Using high‐resolution satellite images, the present study explores the distributions of three presumed periglacial landforms (thermal ...

We present a natural extension of the notion of nondegenerate rational maps (quadrirational maps) to arbitrary dimensions. We refer to these maps as $2^n-$rational maps. In this note we construct a rich family of $2^n-$rational maps. These maps by construction are involutions and highly symmetric in the sense that the maps and their companion maps have
