Research on Hardangervidda
Co-worker: Dr Frank. H. Nicholson (LJMU).
This research is focusing on cold environment weathering in a high
mountain plateau environment, with particular emphasis on rock weathering processes,
periglacial phenomena and landform evolution.
Past student projects have included:
- Investigating postglacial weathering of roche moutonnee in relation to bedrock structure.
- Sediment properties and structure of solifluction lobes.
- Water quality and its role in determining invertebrate diversity and spatial distribution.
- Characteristics and variations in bedrock weathering under shallow sediment and soil burial.
In addition, the expedition leaders worked on:
- Origin, morphology and geomorpholic history of rock streams
- Characteristics and spatial variation in sub-nival bedrock weathering.
- Fungal weathering at the margins of, and beneath, late-lying snowpatches.
- Characterictics and processes of ploughing boulders.
- Monitoring total displacement of
ploughing boulders and frost heave blocks over several seasons, both in summer
Typical view of the plateau
around Snoskar and Rekking. Note the abundance of frost-shattered debris
and ice-moulded forms.
LABORATORY ANALYSES & MONITORING
- Lithological and structural hand
specimen and rock core description (including petrological analysis)
- Mechanical properties (eg tensile strength and ultrasonic velocity)
- Void dependent properties (eg
SEM image analysis of pore structure and microcrack
type and distribution)
- Geochemical properties
(eg composition of intact rock and weathering
- Particle size analysis of sub-ploughing
boulder soils and patterned ground soils
