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. This data set contains meteorological, oceanographic and ship data collected during the International expedition Petermann, which was an international research cruise using the icebreaker Oden in the Arctic Ocean. Data include meteorological variables: Air temperature, Humidity, Wind direction/speed, Atmospheric pressure, Cloud height/cloudiness, Photosynthetic Active Radiation (PAR). Oceanographic variables: Sea water temperature, Conductivity, Salinity and Sound velocity. Ship data: Position, Speed, Course, Water depth. Quality Information: Obviously erroneous data (e.g. negative air pressure) have been omitted. No other processing or quality check of the data has been undertaken. Users ...
