DESCRIPTION:Abstract: Daily satellite images reveal the drastic impact the 
 melting of glaciers and the thawing of permafrost have on the coastal dyna
 mics of the Canadian Arctic. Unlike the terrestrial domain\, less than 20%
  of the seafloor is mapped and most areas are only mapped once\, hindering
  our ability to observe seabed changes in response to cryospheric processe
 s. This presentation will showcase recent examples of seabed changes in re
 sponse to glacier melting and permafrost thaw in the eastern Canadian Arct
 ic. It will specifically address the role of icebergs in generating marine
  geohazards such as submarine landslides and turbidity currents and the ro
 le of permafrost thaw on modifying seabed geomorphology. These examples wi
 ll highlight the importance of seafloor maps and the monitoring of marine 
 sedimentary processes\, especially in a changing climate.\n\nSpeaker: Alex
