| Description | DEGLASEIS is a temporary amphibian seismic network in the NE Greenland region with the following objectives: •Understand the relation of seismicity to NE Greenland deglaciation processes based on a lowered detection threshold and an improved characterization of seismic sources including location, focal depth and mechanism of seismic events The seismic network consists of seven ice-going ocean bottom and five land seismic stations to monitor continuously seismicity and ambient seismic noise for a period of 12 months. Four ocean bottom stations are spaced by about 50 km in deepest locations at Lena Trough between 81°N and 82°N, and another three ocean bottom stations are located north of 82°N on the narrow Wandel Sea shelf off NE Greenland. Three land seismic stations were installed by helicopter from board R/V Polarstern close to the coast between 79°N and 80°N and two stations at about 83°N. Some of the land sites are co-located with geodetic station sites, where time series of vertical movements are available. The project is a cooperation between AWI Bremerhaven, Germany, and GEUS Copenhagen, Denmark. |
