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, …

Controls on terminus change of marine terminating glaciers in Greenland over the last 40+ years
… possible future contributions to sea level. Ice dynamics, or changes due to changes in ice flux, is dominated by the behavior of fast-moving outlet glaciers in Greenland. These glaciers are changing through melting of the terminus face and/or calving of icebergs; the combination of these …

Modeling Subglacial Hydrology in the Himalayas
The snowpack and glaciers of the Himalaya-Karakoram range feed several major river systems in Asia which provide water to over a billion people. Glacial retreat, glacial lake outburst flooding (GLOFs), surge behavior, and glacial ice mass balance are all likely strongly affected by subglacial …

The hydrology of debris-covered glaciers
Studies of glacier-hydrology have focused on clean Alpine glaciers, and recently ice sheet outlet glaciers, but there are few studies on debris-covered glaciers. It is known debris affects ablation rates, and that debris-covered glaciers evolve differently to their debris-free counterparts, but how …

Tracking retreat processes at the Falljökull Glacier, SE Iceland
… that the relationship between ice melt and ice dynamics is non-linear because subglacial drainage configuration strongly modulates meltwater inputs and results in asynchroneity between surface melt production and ice movement. Furthermore, subglacial drainage undergoes temporal evolution and can …

Investigating fast flow of the Greenland Ice Sheet
… understood, and parameterised processes of glacier dynamics due to a paucity of direct observation. To better understand these processes in the wake of a changing climate, novel in-situ geophysical experiments were undertaken on Store Glacier in west Greenland to quantify rates of englacial …

Connect Store: A fully coupled 3D model of ice flow, calving, subglacial hydrology and ice-ocean interactions applied to Store Glacier, Greenland
… model Elmer/Ice to investigate the coupled dynamics of the ice-calving-subglacial-hydrology-plume system at Store Glacier, a large, fast-flowing tidewater outlet glacier on the west coast of Greenland. Understanding these large outlet glaciers is critical to being able to accurately predict …

The future of Narsap Sermia: Documenting the retreat of a tidewater glacier in Southwest Greenland
The behaviour of Greenland’s tidewater glaciers is crucial for the understanding of the Greenland Ice Sheet. The retreat of those marine-terminating glaciers has far-reaching implications, impacting not only the regional hydrography but also the diverse fjord ecosystems. Here, this study …

APPLICATION OF CARBON CREDITS IN THE ITALIAN AND PAKISTANI AGRI-FOOD SECTOR
… like Sentinel-1 and Sentinel-2, to monitor glacier dynamics. This includes tracking glacier retreats, analyzing melt patterns, and assessing changes in ice mass in regions impacted by GHG emissions, such as Pakistan. Advanced remote sensing techniques offer a more efficient, cost-effective, …

Glacier Surge Dynamics on Western Axel Heiberg Island, Nunavut
Surge-type glaciers experience cyclical variations between long periods of slow flow, followed by shorter periods of rapid flow. These glaciers have been thoroughly analysed in many regions, but detailed studies of surging in the Canadian Arctic are lacking. This thesis provides the first …
