17 SAMCoT • ANNUAL REPORT 2015
Monitoring of Sea Ice and Iceberg Drift, Mechanical Properties of
Ice and Applied Oceanography
• CTD and ADCP profiling around iceberg in the Wahlenberg Fjord in April 2015
• Profiling of two icebergs in the Wahlenberg Fjord and one iceberg in the Advent Fjord has been performed
with Laser scanner (Riegl Vz-1000) in April and May 2015
• Monitoring of iceberg drift and rotation in the Advent Fjord was performed from two cameras installed on
the shoreline
• Characteristics of ice drift and surface currents in the North-West Barents Sea and Svalbard region were
investigated and compared using the data from ice trackers deployed on drift ice and icebergs, and data
from floating buoys provided by NOAA
• Original in-situ equipment to study tensile, compressive and shear strength of floating ice was designed and
deployed on sea ice in March and on fresh ice in October 2015
• Experiments on flexural strength of sea ice strengthened by synthetic nets were performed in March 2015
• Original tests on torsion were designed and performed with floating L-shaped cantilever beams on sea ice
in March and on fresh ice in October 2015
• Original tests on friction between floating sea ice blocks were designed and performed on land-fast ice in
March 2015
• CTD and ADCP profiling was performed in shallow coastal zones in the Braganzavagen and near
Paulabreen Glacier in the Van Mijen Fjord. The influence of shallow depth and ice on sea water salinity
increase was investigated in the Braganzavagen. The influence of fresh water discharge on the seabed
erosion, increase of ice thickness and freshening of the under-ice water layer was investigated near
Paulabreen front
• Data on sea currents, velocities and tides were collected near the floating quay in Longyearbyen. Data are
useful for the design project of a new floating quay in Longyearbyen
• Data on surface currents in Advent fjord and Akselsundet were collected with ice drifters using AstroDog
antennas and MetOcean Buoys in October-November 2015
• ADCP AWAC was deployed from the tag boat in the navigational strait Akselsundet for the high frequency
measurement of vertical profiles of sea currents according to a request from the port captain in Svea
• Modelling of iceberg drift and rotation in the Greenland Sea
• Modelling of passive turn-on-a-spot of a turret-moored vessel in conditions of closed drift ice
