Two large cracks, Chasm 1 and the ‘Halloween Crack’, are growing on the Brunt Ice Shelf in Antarctica and when they meet, a large iceberg around 3 times the size of Leeds (1,594 km2) will break off.

McDonald Ice Rumples on Brunt Ice Shelf

Where the Brunt Ice Shelf, growing inexorably from the edge of the Antarctic Ice Sheet, meets a obstacle protruding from the sea floor, the McDonald Ice Rumples are formed – a region of ice deformation, rift generation and shelf fracture. The animation combines images every week or so from the ESA Copernicus Sentinel-1 satellites.

In recent years fracturing has increased and Brunt Ice Shelf will soon lose an area the size of Greater London to a large calving event. Although significant in the known history of this ice shelf, this is believed to be a natural part of the cycle of growth and decay (de Rydt et al., 2019).

RADARSAT-1 Open Data Survey

Click here to fill out the survey.

Canada’s RADARSAT-1 was the first operational radar-based Earth Observation Satellite. RADARSAT-1 acquired numerous data collections from 1995 to 2013. The historical value of this data is clear as it allows making comparisons using images of the same region acquired over the years: for example, to study climate change effects.

The Canadian Space Agency has recently released over 37 000 RADARSAT-1 images for public use, free of charge; you can download them here. In light of this initiative, we are evaluating the feasibility of opening up more RADARSAT-1 data over Canada and internationally. Please answer the survey before 2019-06-28, by (Clicking here) in order to help us better understand your needs and preferences with respect to RADARSAT-1 data.

If you have already filled out this survey, please ignore this email. If you know other people who would like to fill out the survey, please provide them with this link: https://forms.gle/QRpso98XpTj2fnHF6. For any questions please contact julie.claveau@canada.ca
