Abstract
This project was undertaken with the financial support of the Government of Canada through Environment and Climate Change Canada and through the Polar Knowledge Canada project ‘Safe Passage’. Funding from the Canadian Foundation for Innovation and the Ontario Research Fund supported the purchase of computer equipment. RADARSAT-1 and -2 data were supplied by the Canadian Ice Service through a Joint Project Agreement.
Highlights
Three recent calving events from the Petermann Glacier, northwest Greenland (80°45′N, 60°45′W) generated hundreds of individual ice islands that traversed through Nares Strait, Baffin Bay and the Labrador Sea
Its most notable and unique characteristic is the establishment of a lineage connecting all monitored ice islands down to 0.25 km2
Quality-controlled areal extents of the initial ice islands that were generated after recent Petermann Glacier calving events are reported with error magnitudes calculated from project-specific error assessments
Summary
Three recent calving events from the Petermann Glacier, northwest Greenland (80°45′N, 60°45′W) generated hundreds of individual ice islands that traversed through Nares Strait, Baffin Bay and the Labrador Sea. They play a role in the spatial dispersion of fresh water from the Greenland Ice Sheet (Marson and others, 2017) and can be of local importance to marine ecosystems by altering the chemical and physical composition of the water column (Stern and others, 2015) and creating special habitats for phytoplankton, diatoms, bacteria and krill (Vernet and others, 2012; Smith and others, 2013). The database will be publically available in the summer of 2018
