Learning outcomesOn successful completion of this module students should be able to:
CHARACTERISE AND DESCRIBE THE PHYSICAL RELATIONSHIPS BETWEEN CLIMATE CHANGE AND ICE-MASS RESPONSE.
CHARACTERISE PROCESSES OF GLACIER MOTION AND THE RELATIONSHIPS BETWEEN THAT MOTION AND (A) THE STRUCTURAL FORM OF ICE MASSES, AND (B) THE TRANSPORT AND DELIVERY OF SEDIMENTS BY ICE MASSES.
CONCEPTUALISE AND ILLUSTRATE THE FUNCTIONING OF GLACIERS AS HYDROLOGICAL SYSTEMS, ABLE TO STORE AND RELEASE WATER INTO THEIR SURROUNDING ENVIRONMENTS.
DESCRIBE AND ILLUSTRATE THE OPERATION OF ICE MASSES AS HAZARDS IN MANY PARTS OF THE WORLD.
APPRECIATE THE RELATIVE STRENGTHS AND WEAKNESSES OF THE TECHNIQUES EMPLOYED IN GLACIOLOGICAL INVESTIGATIONS, AND TO EVALUATE CRITICALLY AND TO SYNTHESIZE CONTEMPORARY GLACIOLOGICAL RESEARCH.
The module aims to provide a thorough training in the physical processes that govern ice mass behaviour, including response to climate change, motion, hydrology and sedimentation. Much of the module will be guided by contemporary research examples and the module will include a strong fieldwork component. To achieve this aim, students will acquire a firm training in analysing and representing:
relationships between ice masses and climate.
glacier motion processes and processes of sediment incorporation, transport and deposition.
the functioning of glaciers as hydrological systems.
the techniques employed in glaciological and glacial-sedimentological investigations.
