Marine Geological Hazards (6) Marine Geoscience, Geological Survey of Canada and Seabed Disturbance: Extensive multibeam (Sidney, BC, Canada) echosounding surveys have recorded more than 250 submarine slope failures in inner Frobisher Bay. The Frobisher Bay is one of the few locations in impacts of geological hazards on the marine benthos the eastern Canadian Arctic with a long history of inhabiting Baffin Island estuaries are poorly known. geological and ecological study, providing long-term Mass movement processes operating in Baffin Island datasets and study areas that facilitate longitudinal fjords include debris flows initiated on the upper slopes studies of marine habitat change. The bay presents of fjord-head deltas and rockfalls initiated on steeply the perfect opportunity to demonstrate the capabilities sloping valley walls. Debris flows are associated of geological and ecological seabed mapping for with macrofaunas characterized by low density and understanding and managing coastal environmental diversity, while rock falls place coarse rock clasts change in Canada’s Arctic. This research project into deep water, where they create important habitats combines seabed sampling (i.e., grab samples, box for epifauna dependent on hard-bottom substrates. cores, piston cores, Agassiz trawls, video recording) Like the aforementioned mass movement processes, and multibeam echosounding surveys to assess submarine slope failures in inner Frobisher Bay occur benthic habitats, benthic biodiversity, and geological episodically.

International connections: In 2016, PDC was approved LeDrew as Canada’s National Antarctic Data Centre (NADC) Polar Data Catalogue/Canadian Cryospheric and as a member of the World Data System, both Information Network, University of Waterloo (Waterloo, of which represent growing confidence in the PDC Canada) and increasing connection to the international data community. As Canada’s NADC, we are working with For the last decade, the Polar Data Catalogue Polar Knowledge Canada to provide data management (PDC, https://polardata.ca) has been the chosen services to Canada’s Antarctic research community and repository for data and information produced by to share Antarctic metadata with the Global Change the ArcticNet scientific community. The PDC, Master Directory. • Data publication: In collaboration headquartered at the Canadian Cryospheric Information with DataCite International and the National Research Network, University of Waterloo, archives and serves Council of Canada, we are registering Digital Object online data files and metadata records describing Identifiers (DOIs) for ArcticNet and other datasets in the datasets from ArcticNet and other polar research and PDC. DOIs for data are similar to DOIs for published monitoring programs in Canada and around the world. scientific articles in that they link to a unique web To improve our service to the ArcticNet community and location where a dataset can be permanently found, other partners and users, we have made the following and they provide credit and visibility to researchers enhancements to the PDC during 2016: • New data in who contribute data to the PDC. We look forward the PDC: Since 2015, our data collection has grown to working with the ArcticNet community to make from approximately 200,000 data files to more than progress on archiving and registering DOIs for the many 2.7 million, and the number of metadata has grown valuable ArcticNet data sets produced since 2004. to over 2,440 records. In addition, two RADARSAT mosaics of Antarctica have been added to the PDC satellite image collections (https://www.polardata.ca/ RESEARCH PRIORITIES IN THE GWICH’IN pdcsearch/), providing the first full-continental snapshot SETTLEMENT AREA: from 1997 which can now be compared to subsequent mosaics from 2000 and 2008.
