Petermann 2015 Expedition - Meteorological, Oceanographic and Ship Data Collected Onboard Icebreaker Oden during July to September 2015

Creator/Principal investigator(s):

Description:

Petermann 2015 was an international research expedition to the area around the Petermann glacier in northwestern Greenland. The Swedish icebreaker Oden served as the platform for the research carried out in the sea, on the glacier and on land.

The expedition examined the relatively unexplored outlet end of this large system, by documenting changes in the grounded Petermann Glacier, its buttressing ice shelf, and ocean conditions since the end of the last glacial period. Primary scientific questions included:
How sensitive is Petermann ice shelf extent to documented climate changes within the Holocene?
Is ice-shelf response independent of, or linked to, variations in the grounded Petermann Glacier, ocean thermal conditions, or relative sea level (i.e., sill depth)?
What are the rates of change and variability of these systems in response to early Holocene warming, Neoglacial cooling, and post-Neoglacial (late 19th century to present) warming?

Purpose:

The purpose of the project was to collect multibeam bathymetry and sub-bottom profile information along the western continental shelf of Greenland in order to characterize the shape of the seafloor and uppermost sediment properties. The main goal was to increase our understanding about potential pathways of relative warmer water influx towards Greenland’s many outlet glaciers.
