Julian Murton (University of Sussex) and Mark Bateman (University of Sheffield) initiated a project on sand-sheet development in the Tuktoyaktuk Coastlands, Western Canadian Arctic, in July 2001, and funded by the Royal Society.
The project is determining the temporal relationships between sandsheet formation and known changes of climate, active- layer depth, vegetation and glaciation, in order to establish the natural controls on and timing of aeolian sand-sheet development during the last glacial-interglacial cycle in the Tuktoyaktuk Coastlands. Samples were collected for luminescence and radiocarbon dating, and stratigraphic and sedimentological observaobservations were recorded. Interestingly, multiple levels of sand veins and wedges were observed in the sand sheets, the highest syngenetic wedges recorded within the Kittigazuit Formation on Richards Island exceeded 9 m. Future work seeks to clarify the complex stratigraphic relationships between sand-sheet, sand-dune and glacigenic deposits along the northern coast of Liverpool Bay, beyond the mapped limit of Wisconsinan glaciation.
Charles Harris (University of Cardiff) and Michael Davies (University of Dundee), in collaboration with Johan Ludvig Sollid (University of Oslo) established a process monitoring station at Steinhoi, Dovrefjell, Norway in July 2001, funded by the British Natural Environment Research Council. A steel frame was ininstalled on which is mounted a pair of Linear Voltage Displacement Transducers (LVDTs), to record ground surface movements (heave/settlement and down slope displacement). Thermistor strings and Druck miniature pore water pressure transducers were also deployed to monitor seasonal ground freezing and thawing, and associated pore water pressure variations. Data is recorded by a Campbell logger that is linked to Cardiff and Dundee via a mobile phone, making it possible to interrogate the station on a daily basis. Rudberg columns were also installed for longterm measurement of displacement profiles. The aim is to generate field data for validation of recent laboratory simulation studies.
