The engineering feasibility of several potential methods for inducing the large scale fracturing of icebergs has been investigated. These methods included conventional explosives and incendiaries, thermal fracture of ice, various sorts of directed beams (radiation, fluid or particles), injected pressurized fluid (both confined and unconfined) and an ice cutting method using an electrically heated wire. All methods had in common the requirement for large quantities of materials and/or energy. Some methods, while technically and perhaps economically feasible, were unacceptable from an environmental viewpoint.

Most of the mass loss from the Antarctic Ice Sheet (AIS) occurs by dynamic flow of ice from the interior of the ice sheet to the margins, where the ice flows on the ocean, ultimately breaks apart into icebergs, and melts into the ocean. Due to anthropogenic-caused shifts in the climate system, many glaciers in the AIS are accelerating and thus increasing the contribution of the AIS to global sea-level rise. Understanding, and subsequently projecting, the behavior of these Antarctic glaciers is necessary to constrain the impacts that climate shifts will have on the Earth system and on communities around the world. To this end, the essential knowledge needed relates to the physical processes governing the flow and fracture of ice, some of which are unknown and most under-explored. This thesis seeks to illuminate these processes. I take a three-pronged approach to this question: harnessing satellite and field observations, developing theory, and improving ice flow models to represent completely the feedbacks that affect ice flow and fracture. In the first section of this thesis, I develop a novel technique to estimate both the ice-rock interface conditions and ice viscosity from satellite observations simultaneously. When applying this method, I find that ice is less viscous in the regions of glaciers that deform the fastest. In the next section, I consider the mechanisms causing the reduction of ice viscosity. Firstly, I evaluate magnitude of heating by viscous dissipation and show that in many regions of ice streams, shear heating may create temperate zones from which meltwater drains to the bed. Secondly, I find that changes to the ice microstructure likely play a significant role in rates of ice flow and fracture. In the final section, I propose a framework for including these new processes into ice flow models and construct a method for dynamically evaluating these parameters within ice sheet models. As a result of this work, we have a more complete view of the drivers of accelerating ice mass loss and a path forward for modeling future ice flow more accurately, which will improve projections of future sea-level rise.

Iceberg Utilization covers the proceedings of the First International Conference and Workshops on Iceberg Utilization for Fresh Water Production, Weather Modification and Other Applications, held at Iowa State University, Ames, Iowa, USA on October 2-6, 1977. The book focuses on the efforts to consider the feasibility of using icebergs as alternative water and energy resources relative to the growing concern on global water and energy shortage. The compilation first offers information on the patterns of cooperation in international science and technology and evaluation of subsidiary effects and concomitant issues and challenges in iceberg utilization. The text also looks at the consideration of icebergs as potential water resource, including arctic drifting stations, remote sensing, and transport of icebergs. The book discusses elements of iceberg technology and remote sensing of thickness of icebergs, as well as sources and properties of tabular icebergs and towing, handling, processing, and selection of icebergs. The text also considers the international law problems in the acquisition and transportation of Antarctic icebergs; ecological considerations of iceberg transport from Antarctic waters; and energy and freshwater production from icebergs. The selection is a dependable reference for readers wanting to explore the potential of icebergs as energy and water resource.
