This week’s Photo Friday features images from a research project in Svalbard. GlacierHub has interviewed two members of the research team.
Nick Hulton, a team member, explained:
Kronebreen is one of the fastest flowing glaciers in Svalbard, which is an Arctic archipelago situated north of mainland Norway. The glacier drains a large ice cap, transferring ice down a narrow valley that terminates within a fjord, producing a dramatic 3 km-wide ice cliff. The CRIOS (Calving Rates and Impact on Sea Level) research group, headed by Prof. Doug Benn, has been working there for a number of years to better understand how and when ice will be transferred to the oceans, and how this will affect future global sea levels.
Two CRIOS members, Penny How and Nick Hulton from the University of Edinburgh and the University Centre in Svalbard (UNIS), are using time-lapse cameras to understand how this glacier is changing and the processes that cause icebergs to break off into the ocean. The cameras take high-resolution pictures every thirty minutes, and by tracking individual features form image to image, can be used to measure how fast the glacier is flowing.
Penny How, a research student in the team, added “We are currently putting 11 time-lapse cameras at Kronebreen, in an attempt to generate sequential digital elevation models using Structure from Motion (i.e. three-dimensional time-lapse).”
Videos produced from these images give a good impression of how the glacier moves and can be seen here:
This one gives a taste of the fieldwork involved to install these time-lapse cameras:
