Calving Processes and the Dynamics of Calving Glaciers ⁎ Douglas I
Earth-Science Reviews 82 (2007) 143–179 www.elsevier.com/locate/earscirev Calving processes and the dynamics of calving glaciers ⁎ Douglas I. Benn a,b, , Charles R. Warren a, Ruth H. Mottram a a School of Geography and Geosciences, University of St Andrews, KY16 9AL, UK b The University Centre in Svalbard, PO Box 156, N-9171 Longyearbyen, Norway Received 26 October 2006; accepted 13 February 2007 Available online 27 February 2007 Abstract Calving of icebergs is an important component of mass loss from the polar ice sheets and glaciers in many parts of the world. Calving rates can increase dramatically in response to increases in velocity and/or retreat of the glacier margin, with important implications for sea level change. Despite their importance, calving and related dynamic processes are poorly represented in the current generation of ice sheet models. This is largely because understanding the ‘calving problem’ involves several other long-standing problems in glaciology, combined with the difficulties and dangers of field data collection. In this paper, we systematically review different aspects of the calving problem, and outline a new framework for representing calving processes in ice sheet models. We define a hierarchy of calving processes, to distinguish those that exert a fundamental control on the position of the ice margin from more localised processes responsible for individual calving events. The first-order control on calving is the strain rate arising from spatial variations in velocity (particularly sliding speed), which determines the location and depth of surface crevasses. Superimposed on this first-order process are second-order processes that can further erode the ice margin. -

Young, Supervisor Kelley A. Crews Gregory W. Knapp Daene C. McKinney Francisco L. Pérez “They Are Drying Out”: Social-Ecological Consequences of Glacier Recession on Mountain Peatlands in Huascarán National Park, Peru by Mary Harding Polk, B.A., M.A. Dissertation Presented to the Faculty of the Graduate School of The University of Texas at Austin in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy The University of Texas at Austin May 2016 Acknowledgements The journey to the Cordillera Blanca and Huascarán National Park started with a whiff of tear gas during the Arequipazo of 2002. During a field season in Arequipa, the city erupted into civil unrest. In a stroke of neoliberalism, newly elected President Alejandro Toledo privatized Egesur and Egasa, regional power generation companies, by selling them to a Belgian entity. Arequipeños violently protested President Toledo’s reversal on his campaign pledge not to privatize industries. Overnight, the streets filled with angry protesters demonstrating against “los Yanquis.” The President declared a state of emergency that kept Agnes Wommack and me trapped in our hotel because the streets were unsafe for a couple of Yanquis. After 10 days of being confined, we decided to venture out to the local bakery. Not long after our first sips of coffee, tear gas floated onto the patio and the lovely owner rushed out with wet towels to cover our faces. -
Seismic Model Report.Pdf
Scientific Report GEFSC Loan 925 The Character and Extent of subglacial Deformation and its Links to Glacier Dynamics in the Tarfala Basin, northern Sweden Jeffrey Evans, David Graham, and Joseph Pomeroy Polar and Alpine Research Group, Loughborough University ABSTRACT A pilot passive seismology experiment was conducted across the main overdeepening of Storglaciaren in the Tarfala Basin, northern Sweden, in July 2010, to see whether basal microseismic waveforms could be detected beneath a small polythermal arctic glacier and to investigate the spatial and temporal distribution of such waveforms in relation to known glacier flow dynamics. The high ablation rate made it difficult to keep geophones buried and well- coupled to the glacier during the experiment and reduced the number of days of good quality data collection. Event counts and the subsequent characterisation of typical and atypical waveforms showed that the dominant waveforms detected were from near-surface events such as crevassing. Although basal sliding is known to occur in the overdeepening, no convincing examples of basal waveforms were detected, which suggests basal microseismic signals are rare or difficult to detect beneath polythermal glaciers like Storglaciaren, a finding that is consistent with results from alpine glaciers in Switzerland. The data- set could prove useful to glaciologists interested in the dynamics of near-surface events such as crevassing, the opening and closing of englacial water conduits, or temporal and spatial changes in the glacier’s stress field. Background Smith (2006) found that pervasive soft-bed deformation characterised parts of the Rutland Ice Stream in West Antarctica and produced 6 times fewer basal microseismic signals than regions where basal sliding or stick slip movement dominated. -

Determining Rock Surface Micro-Roughness and Search For
Landform Analysis, Vol. 21: 3–8 (2012) Determining rock surface micro-roughness and search for new method of relative dating of glacial landforms; a case study from Fláajökull (SE Iceland) and Biferten glacier (Swiss Alps) forefields Maciej Dąbski Department of Geomorphology, Faculty of Geography and Regional Studies, University of Warsaw, Poland, e-mail: [email protected] Abstract: Micro-roughness was recorded on glacially abraded stones deposited since Little Ice Age by two glaciers: Fláajökull in SE Iceland (basalts) and Biferten glacier in Swiss Alps (limestones) in order to find indices of relative age of the glacial landforms. Micro-roughness of rock surfaces was analysed with use of Handysurf E35-B electronic profilometer which calculates following roughness parameters: Rz, Rzmax, Ra and Rsm. An increase in roughness parameters towards older moraines is observed in both forefields, however the change is more significant on limestone surfaces. Time-depend- ent surface deterioration is visible only within first decades of weathering of both types of rock, and further weathering does not cause increase in micro-roughness. Keywords: Micro-roughness, proglacial weathering, Fláajökull, Iceland, Biferten glacier, Swiss Alps Introduction Previous measurements of rock surface (micro) roughness in relative dating of glacial landforms were performed on gneiss within Storbreen forefiled (McCarroll 1992) and in Oldedalen (McCarroll & Nesje 1996). In both cases a hand profilometer was used which enabled measurement of relative heights of micro-depressions and micro-elevations with a theoretical precision up to 0.01 mm, and the range of micro-denivelations was usually 0.5–6 mm. Results proved to be useful in roughness differentiation be- tween Little Ice Age (LIA) landforms and those from the onset of Holocene. -

To 14 address this knowledge gap, we collected repeat, spatially extensive high-frequency 15 ground-penetrating radar (GPR) observations on two glaciers in Alaska during the spring 16 of five consecutive years. GPR measurements showed steep snow water equivalent 17 (SWE) elevation gradients at both sites; continental Gulkana Glacier’s SWE gradient 18 averaged 115 mm 100 m–1 and maritime Wolverine Glacier’s gradient averaged 440 mm 19 100 m–1 (over >1000 m). We extrapolated GPR point observations across the glacier 20 surface using terrain parameters derived from digital elevation models as predictor 21 variables in two statistical models (stepwise multivariable linear regression and 22 regression trees). Elevation and proxies for wind redistribution had the greatest 23 explanatory power, and exhibited relatively time-constant coefficients over the study 24 period. Both statistical models yielded comparable estimates of glacier-wide average 25 SWE (1 % average difference at Gulkana, 4 % average difference at Wolverine), 26 although the spatial distributions produced by the models diverged in unsampled regions 27 of the glacier, particularly at Wolverine. -
