    Description / Table of Contents: This volume examines the processes responsible for sedimentation in modern glacimarine environments, and how such modern studies can be used as analogues in the interpretation of ancient glacimarine sequences. Sediments released from glaciers grounded in tidewater, floating ice shelves, ice tongues, icebergs and sea ice form complex sequences governed by glaciological, oceanographic, sedimentary and biogenic controls. Ten per cent of the world’s oceans and epicontinental seas contain such active glacimarine environments, but during Cenozoic glacial periods this area was doubled. This book will, therefore, be of relevance to all scientists concerned with high and middle latitude marine environments. The early chapters are concerned largely with processes of sedimentation in modern glacimarine environments; examples are drawn from Alaska, the Canadian Arctic, Svalbard and Antarctica. Studies of ancient sequences, both Cenzoic and pre-Cenozoic, from the Barents Sea, Greenland, Sweden, Alaska and the northwest European continental shelf, form the latter part of the book.

    Notes: Supervised classification of digital Landsat satellite images was used to locate seabird nesting habitats in the Russian High Arctic archipelago of Franz Josef Land, a region where the avifauna is poorly known and ecologically vulnerable. Major seabird nesting colonies are readily identifiable in Landsat Thematic Mapper (TM) imagery of the region due primarily to the distinctive spectral signature of vegetation on ornithogenically altered soils below bird cliffs. Supervised image classification was used to pinpoint areas displaying spectral characteristics typical of documented seabird nesting habitats. A total of 101 seabird nesting colony locations identified in Russian and Western literature from 1898 to 1996 was used as training sites to develop spectral signatures from a summer TM image mosaic for use in a supervised maximum likelihood classification. The classified image was thresholded and compared to a map of documented nesting locations. Of the 101 field-documented nesting sites, 96 were clearly identified in the classified image. An inventory was produced of all undocumented seabird habitats suggested by the classification, totalling over 300 sites. The methodology used may be applicable to other arctic regions and is intended as a first step when planning ecological protection zones in remote and inaccessible arctic regions.

    Notes: The ice masses on Edgeøya and Barentsøya are the least well known in Svalbard. The islands are 42-47% ice covered with the largest ice cap, Edgeøyjøkulen, 1365 km2 in area. The tidewater ice cliffs of eastern Edgeøya are over 80 km long and produce small tabular icebergs. Several of the ice-cap outlet glaciers on Edgeøya and Barentsøya are known to surge, and different drainage basins within the ice caps behave as dynamically separate units. Terminus advances during surging have punctuated more general retreat from Little Ice Age moraines, probably linked to Twentieth Ceutury climate warming and mass balance change. Airborne radio-echo sounding at 60 MHz along 340 km of flight track over the ice masses of Edgeøya and Barentsøya has provided ice thickness and elevation data. Ice is grounded below sea level to about 20 km inland from the tidewater terminus of Stonebreen. Ice thickens from 〈100 m close to the margins, to about 250 m in the interior of Edgeøyjøkulen. The maximum ice thickness measured on Barentsjøkulen was 270 m. Landsat MSS images of the two islands, calibrated to in-band reflectance values, allow synoptic examination of snowline position in late July/early August. Snow and bare glacier ice were identified, and images were digitally stretched and enhanced. The snowline was at about 300 m on the east side of Edgeøyjøkulen, and 50-100 m higher to the west. Snowlines were at approximately 450 m on Digerfonna and Storskalven. On Barentsjøkulen the snowline was 350 m above sea level on the eastern flank and over 400 m on the west. This asymmetry suggests greater precipitation on the east side of the ice caps. Enhanced Landsat imagery was also used to identify suspended sediments in the waters offshore of the islands. Where this turbid meltwater emerges from tidewater glacier termini, it is likely to be derived from the subglacial drainage system. This suggests that at least parts of the beds of the ice masses on Edgeøya and Barentsøya are at the pressure melting point, and that a basal hydrological system is present.

    Notes: The identification of surge activity is important in assessing the duration of the active and quiescent phases of the surge cycle of Svalbard glaciers. Satellite and aerial photographic images are used to identify and describe the form and flow of Perseibreen, a valley glacier of 59 km2 on the east coast of Spitsbergen. Heavy surface crevassing and a steep ice front, indicative of surge activity, were first observed on Perseibreen in April 2002. Examination of high resolution (15 m) Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) satellite imagery confirmed this surge activity. Perseibreen retreated by almost 750 m between 1961 and 1990. Between 1990 and the summer of 2000, Perseibreen switched from retreat and its front began to advance. Rapid advance was underway during the period June 2000 to May 2001, with terminus advance at over 400 m yr−1. Between May and August 2001 the rate increased to over 750 m yr−1. The observed crevasse orientation indicates that ice was in longitudinal tension, suggesting the down-glacier transfer of mass. Ice surface velocities, derived from image correlation between ASTER images, were 2-2.5 m d−1 between May and August 2001. The glacier was flowing at a relatively uniform speed with sharp velocity gradients located close to its lateral margins, a velocity structure typical of ice masses in the active phase of the surge cycle. The stress regime is extensional throughout and the surge appears to be initiated low on the glacier. This is similar to the active-phase dynamics of other Svalbard tidewater glaciers. Perseibreen has probably been inactive since at least 1870, a period of about 130 years to the present surge which defines a minimum length for the quiescent phase.
