Basal conditions beneath a soft-bedded polythermal surge-type glacier: Bakaninbreen, Svalbard
Murray, T.; Porter, P.R. (2001)Bakaninbreen, Svalbard is a subpolar glacier that began a prolonged surge in 1985. A steep surge-front propagated downglacier at rates of up to 470 cm day−1 over the period 1985–1995. During 1994 and 1995 the glacier was ... -
Chemical denudation and silicate weathering in Himalayan glacier basins: Batura Glacier, Pakistan
Hodson, A.J.; Porter, P.R.; Lowe, A.; Mumford, P.N. (2002)The major ion, SiO2 and minor element contents of Batura Glacier meltwaters in the headwaters of the Indus Basin, Pakistan are examined. The data are used to examine the controls upon solute acquisition by runoff and to ... -
Composite suspended sediment particles and flocculation in glacial meltwaters: preliminary evidence from Alpine and Himalayan basins
Woodward, J.; Porter, P.R.; Lowe, A.; Walling, D.E.; Evans, A.J. (2002) -
Geotechnical controls on a steep lateral moraine undergoing paraglacial slope adjustment
Curry, A.M.; Sands, T.B.; Porter, P.R. (2009)Sustained post ‘Little Ice Age’ retreat of the northern lobe of the Feegletscher, Valais, Switzerland, has exposed lateral moraines that show pronounced oversteepening on the upper proximal slopes, with upper-slope segments ... -
Getting the best from PowerPoint: 2 and 3 dimensional animations
Porter, P.R. (2009)PowerPoint is a package that many academics and teachers use routinely in teaching and research; the days of presentations being in the form of carousels loaded with slides are a distant memory for most. PowerPoint offers ... -
Getting the best from PowerPoint: 2 and 3-dimensional animations
Porter, P.R. (2010)The following discussion and examples of animation techniques within PowerPoint follows on directly from the article „Getting the best from PowerPoint: 2 and 3-dimensional anima-tions‟ that was published in the last edition ... -
Glacier surge propagation by thermal evolution at the bed
Murray, T.; Stuart, G.W.; Miller, P.J.; Woodward, J.; Smith, A.M.; Porter, P.R.; Jiskoot, H. (2000)Bakaninbreen, southern Svalbard, began a prolonged surge during 1985. In 1986, an internal reflecting horizon on radio echo sounding data was interpreted to show that the position of the surge front coincided with a ... -
Hydraulic and mechanical properties of glacial sediments beneath Unteraargletscher, Switzerland: implications for glacier basal motion
Fischer, U.; Porter, P.R.; Schuler, T.; Evans, A.J.; Gudmundsson, H. (2001) -
Mechanical and hydraulic properties of till beneath Bakaninbreen, Svalbard
Porter, P.R.; Murray, T. (2001)Bakaninbreen, Svalbard, was in the late phase of a prolonged surge during 1995-96. In order to investigate the nature of the basal mechanical and hydraulic regime, sets of tilt sensors equipped with pore-pressure sensors ... -
Quantitative particle size, microtextural and outline shape analyses of glacigenic sediment reworked by paraglacial debris flows
Curry, A.M.; Porter, P.R.; Irvine-Fynn, T.D.L.; Rees, G.; Sands, T.B.; Puttick, J. (2009)Particle size analysis and scanning electron microscopy have been used with some success to differentiate sediments sampled from varying geomorphological environments. In the paraglacial environment, however, discrimination ... -
Recent High-Arctic glacial sediment redistribution : a process perspective using airborne lidar
Irvine-Fynn, T.D.L.; Barrand, N.E.; Porter, P.R.; Hodson, A.J.; Murray, T. (2010)Progressive glacier thinning, retreat and mass loss in the High-Arctic is increasingly exposing forefield sediments to processes of mobilisation and redistribution. In this paper, we quantify forefield sediment redistribution ... -
Sediment-moss interactions on a temperate glacier: Falljökull, Iceland
Porter, P.R.; Evans, A.J.; Hodson, A.J.; Lowe, A.; Crabtree, M.D. (2008)We present the results of preliminary investigations of globular moss growth on the surface of Falljökull, a temperate outlet glacier of the Vatnajökull ice cap, southern Iceland. Supraglacial debris has provided a basis ...
