How to register for courses in Nuuk

To apply for courses in the Arctic Science Study Programme (ASSP), please complete the “Student Information” form below. After submitting the completed form you will receive an e-mail with details on how to proceed with register for the courses and other practical information.

The ASSP offers graduate (masters) and PhD level courses. The courses in spring and autumn each form two full semester (30 ECTS). Applicants applying for a full semester are given priority, however, it is possible to apply for single courses. You can find more information about the courses under Arctic Science Study Programme (ASSP).

Basin-wide contributions to the underwater soundscape by multiple seismic surveys with implications for marine mammals in Baffin Bay, Greenland Published 21.12.2018

Abstract:

Seismic surveys increasingly operate in deeper Arctic waters with propagation conditions and marine mammal fauna different from the better-studied temperate, or shallow-water, regions. Using 31 calibrated sound recorders, we quantified noise contributions from four concurrent seismic surveys in Baffin Bay, Greenland, to estimate their potential impacts on marine mammals. The impact was cumulative as the noise level rose in response to the onset of each survey: on a minute-by-minute scale the sound-exposure-levels varied by up to 70 dB (20 dB on average), depending on range to the seismic vessel, local bathymetry effects and interference patterns, representing a significant change in the auditory scene for marine mammals. Airgun pulse energy did not decrease to ambient before arrival of the next pulse leaving very little low-frequency masking-free time. Overall, the measured values matched well with pre-season-modeling, emphasizing the importance of noisemodeling in impact assessments, if responses of focal marine mammals are known
