Regolith Erosion at Grinnell Glacier, Glacier National Park
<p>Glacier National Park is located within a mountainous region in western Montana. Due to recent glaciation, moraines are present at the upper elevations throughout the park. These young moraines erode at a rapid pace when first exposed by melting ice due to: age, vegetation cover, local climate, …

GEOPHYSICAL INVESTIGATION OF GLACIER GEOMETRY AND SUBGLACIAL GEOLOGY, AND THEIR INFLUENCE ON GLACIER DYNAMICS: CASE STUDIES OF TAKU GLACIER, ALASKA AND THWAITES GLACIER, WEST ANTARCTICA
Mass loss from glaciers and ice sheets is a significant contributor to the rise of global mean sea level (GMSL) and will continue to be in the future. Rising GMSL will cause displacement of coastal populations, loss of ecosystems and rising food in- security. To plan for and mitigate these impacts, …

Plant Successional Patterns at Sperry Glacier Foreland, Glacier National Park, MT, USA
… have been driving rapid glacial retreat in many glaciers since the Little Ice Age. This retreat provides a unique opportunity to study succession across the chronosequences of glacier forelands. Patterns of plant colonization and succession on terrain exposed by retreating glaciers give insight …

Characterization of the basal hydraulic system of a surge-type glacier : Trapridge Glacier, 1989-92
… hydrology is a critical issue in understanding glacier and ice-sheet dynamics. This is especially true for surge-type glaciers, which are distinguished by their regular, quasi-periodic alternation between slow and fast flow regimes (Meier and Post, 1969); the fast flow during a surge is thought …

Applications of Digital Remote Sensing to Quantify Glacier Change in Glacier and Mount Rainier National Parks
… on glacial landscapes. Characteristics of glaciers from two geographic regions, the Intermountain Region (between the Rocky Mountain and Cascade Ranges) and the Pacific Northwest, were estimated for the years 1985, 2000, and 2015. Glacier National Park was studied for the Intermountain …

Quantifying glacier melt enhancement due to dust deposition during the 2022 melt season. Tungnaárjökull glacier, South Iceland
… of any natural surface, making snow-covered glaciers an important component of the Earth´s energy balance. However, the presence of light absorbing impurities such as mineral dust on glacier surfaces alters their reflective properties leading to a reduction in albedo, consequently increasing …

Spatio-Temporal Vegetation Change as related to terrain factors at two Glacier Forefronts, Glacier National Park, Montana
Glacier retreat is considered a clear sign of global climate change. Although a rich body of work has documented glacial response to climate warming trends, comparatively little research has assessed vegetation change in recently deglaciated areas. In this study, we assess vegetation change at two …

Glacier-ocean interactions in shallow-silled fjords
Glacier-ocean interactions in shallow-silled fjords play a crucial role in the mass balance of marine-terminating glaciers and the transport of freshwater from the ice sheet to the ocean. Despite their importance, the complex dynamics of these systems, influenced by sill processes, freshwater …

Cryogenic carbon cycling at an Icelandic glacier
Glaciers and ice caps are recognised as an important component of the global carbon cycle. Carbon within glacial systems exists in organic and inorganic forms, across supraglacial, englacial and subglacial realms. It is often difficult to detach cryospheric carbon cycling from hydrology, with the …

Glacier surging in the West Kunlun Shan
… third-largest glacial system on Earth, with a glacierised area of ~40 800 km2 (Bolch et al., 2012) and a mass balance of -26 ± 12 Gt a-1: ~10% of the global contribution of the cryosphere to sea level rise (Vaughan et al., 2013). The glaciers of the Karakoram and West Kunlun Shan represent the …

Quantifying Glacier-Derived Summer Runoff in Northwest Montana
Glacier National Park, located in northwest Montana contains the second largest concentration of glaciers in the U.S. Rocky Mountains. However, total glacier-covered area has shrunk by almost 30% over the past 50 years. This has important implications for local glacier-fed streams, especially …

Glacier Monitoring in Ladakh and Zanskar, northwestern India
Glaciers in the Himalaya are often heavily covered with supraglacial debris, making them difficult to study with remotely-sensed imagery alone. Various methods such as band ratios can be used effectively to map clean-ice glaciers; however, a thicker layer of debris often makes it impossible to …
