Mapping "Brain Terrain" Regions on Mars using Deep Learning [PDF]

arXiv, 2023
One of the main objectives of the Mars Exploration Program is to search for evidence of past or current life on the planet. To achieve this, Mars exploration has been focusing on regions that may have liquid or frozen water. A set of critical areas may have seen cycles of ice thawing in the relatively recent past in response to periodic changes in the ...

A Multimethod Investigation of the Lake Agnes Rock Glacier, Colorado, USA

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Rock glaciers are important headwater landforms that play a key role in alpine hydrology. North American rock glaciers are estimated to contain the third largest water volume equivalent globally, and over 3800 rock glaciers have been mapped in Colorado alone. However, these features are often overlooked in alpine water budgets.

Developments in Permafrost Science and Engineering in Response to Climate Warming in Circumpolar and High Mountain Regions, 2019–2024

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Research in geocryology is currently principally concerned with the effects of climate change on permafrost terrain. The motivations for most of the research are (1) quantification of the anticipated net emissions of CO2 and CH4 from warming and thaw of near‐surface permafrost and (2) mitigation of effects on infrastructure of such warming and

Microbial Ecology of Permafrost Soils: Populations, Processes, and Perspectives

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Permafrost microbial research has flourished in the past decades, due in part to improvements in sampling and molecular techniques, but also the increased focus on the permafrost greenhouse gas feedback to climate change and other ecological processes in high latitude and alpine permafrost soils.

Advances in Permafrost Representation: Biophysical Processes in Earth System Models and the Role of Offline Models

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Permafrost is undergoing rapid changes due to climate warming, potentially exposing a vast reservoir of carbon to be released to the atmosphere, causing a positive feedback cycle. Despite the importance of this feedback, its specifics remain poorly constrained, because representing permafrost dynamics still poses a significant challenge for ...

Decadal Variability of Differential Frost Heave on Incipient Sorted Patterned Ground in the Southern Japanese Alps

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Differential frost heave between fine (earthy) and coarse (gravelly) domains was monitored over 10 years (2013–2023) on a mountain‐top flat ground subjected to both frequent diurnal and deep seasonal freezing. Monitoring objects include, ground heave, soil temperature down to 55 cm, soil moisture, air temperature, rainfall, and snow depth. The

A Conceptual Model for Delineating Land Management Units (LMUs) Using Geographical Object-Based Image Analysis

ISPRS International Journal of Geo-Information, 2017
Land management and planning is crucial for present and future use of land and the sustainability of land resources. Physical, biological and cultural characteristics of land can be used to define Land Management Units (LMUs) that aid in decision making ...

Visual Impact Assessment - There's more to it than meets the eye! [PDF]

, 1992
The visual impact of a wind farm is one of the major causes of concern for all current U.K. wind farm projects. Often visual impact is the single most important issue on which a planning application is judged.
