Aerial-photo and LiDAR iceberg surveys during the 2015 Joint Statoil/ArcticNet Cruise, Newfoundland and Labrador, Canada
Amundsen ScienceTriplicate aerial-photo and LiDAR surveys of two iceberg sails were conducted to evaluate the capability of each technique to detect iceberg or ice island deterioration. This evaluation lays out how the spatial pattern and rate of iceberg deterioration could…

Benthic ecosystem functioning in the Arctic
Amundsen ScienceSamples were collected during the Malina programme at 8 sites ranging in water depth from 47 m to 577 m in July and August 2009 onboard the icebreaker CCGS Amundsen. At each sampling station, an USNEL box corer (50 cm×50 cm×30 cm) was deployed for seafloor…

Influence of deep-water corals and sponges gardens on infaunal community composition and ecosystem functioning in the Eastern Canadian Arctic
Amundsen ScienceSamples were collected at two sites in the Eastern Canadian Arctic (Figure 1) aboard the scientific icebreaker CCGS Amundsen. The sampling positions at biogenic and non-biogenic habitats were defined during ROV video surveys at the two sites (Figure 2a-d).…
