The GLAMAR project seeks to examine the impact of subglacial meltwater drainage on the morpho-stratigraphic development of continental margins, with focus on known latitudinal variability in melwater discharge from former ice sheets along the North Atlantic margins. The objective of the GLAMAR research cruise is to investigate a system of seabed sand ridges on the continenttal in the Celtic Sea, in order to test the hypothesis that they record a subglacial drainage system on the shelf, linked to canyons on the slope.
1. Acquire multibeam swath bathymetric data along several ridges.
2. Acquire shallow seismic reflection profiles along and across the ridges.
3. Identify sites for the acquisition of vibrocores from the ridges during a follow-on Irish campaign.
