Mass Balance of the Himalayan Glaciers and Their Regional Variations

Journal of Geography, Environment and Earth Science International, 2019
Aim: Popular methods of glacial mass balance studies are time consuming, laborious and therefore, not repetitive at yearly manner. A compact, user-friendly classification algorithm has been applied to estimate Equilibrium Line Altitude (ELA) and mass balance of mountain or valley glaciers at yearly basis using Synthetic Aperture Radar (SAR) data for a ...

Late Quaternary climatic variability in the Eastern Mediterranean recorded in Hermes Cave, Corinth Rift, Greece

Journal of Quaternary Science, EarlyView.
ABSTRACT The Greek peninsula lies at the intersection of major atmospheric circulation systems, making it a key location for reconstructing past climate variability in the Eastern Mediterranean. In this study, we present a new high‐resolution multi‐proxy speleothem record from Hermes Cave, located on the shoulder of the Corinth Rift in southern Greece.

Table 1: Basic mass-balance, Peyto Glacier, 1967/1974

, 1977
The eight-year record of mass balance of Peyto Glacier is correlated to meteorological data measured near the glacier and at Lake Louise 30 km to the south. The period investigated includes the llighest and lowest accumulations for the past 40 years. The

Velocities of Major Outlet Glaciers of the Patagonia Icefield Observed by TerraSAR-X [PDF]

, 2008
The capabilities of TerraSAR-X data for feature tracking by amplitude correlation over glacier surfaces are investigated. Methodical aspects of the amplitude correlation approach are described.

Geochronological reconstruction of the Lateglacial deglaciation in the Arve Valley (Northern French Alps)

Journal of Quaternary Science, EarlyView.
ABSTRACT The timing and spatial patterns of glaciers retreat in the Northern French Alps during the Lateglacial (19.0–11.7 ka) remain debated, reflecting discrepancies among available chronological data sets. The complex interactions between major glaciers, such as the Rhône and Arve glaciers to the north and the Isère glacier to the south, represent a

Behavioral responses of black bears to human presence and infrastructure in Yosemite National Park

The Journal of Wildlife Management, EarlyView.
Using GPS collar data from black bears in Yosemite National Park, we examined how bear spatiotemporal activity in relation to human development shifted during the COVID‐19 park closure in 2020. In the absence of visitors, bears maintained consistent landscape‐scale space use but altered fine‐scale spatial and temporal behaviors.

A minimal machine learning glacier mass balance model

The Cryosphere
Abstract. Glacier retreat presents significant environmental and social challenges. Understanding the local impacts of climatic drivers on glacier evolution is crucial, with mass balance being a central concept. This study introduces miniML-MB, a new minimal machine learning model designed to estimate annual point surface mass balance (PMB) for very ...

Glacier mass balance Jamtalferner, Silvretta, Austria, 1988/1989

, 2013
The glacier mass balance of Jamtalferner has been measured annually since 1988/1989 with the direct/glaciological method. Winter mass balance has been determined for 1 May in all years.

When a Week Is Not A Week: How Temporal Boundaries Shift Regulatory Focus and Consumer Preference

Psychology &Marketing, EarlyView.
ABSTRACT Does consumer perception of a sales event change if it falls across a calendar boundary (e.g., next month) versus within the current month, holding objective time constant? We investigate this question in the context of Cyber Monday, the global shopping event occurring the Monday after the U.S. Thanksgiving holiday.

High-altitude precipitation controls the mass balance of Pasu Glacier, Karakoram over 2000–2020: A case study based on mass and energy budget

Advances in Climate Change Research
Glaciers in the Karakoram exhibit stability or near-balanced mass changes, in stark contrast to the widespread glacier retreat observed globally. However, the limited availability of observational data, coupled with the lack of in-depth exploration of ...
