Ziel der Reise / Objectives of Cruise:

The warm Gulf Stream and the cold Labrador Current meet in the Northwest Atlantic off Nova Scotia, which leads to the formation of nutrient rich slope waters. Expedition MSM118 NOVAMAR 2 collected water and sediment samples to provide important data for the reconstruction of changes of surface and deeper water masses at the convergence of the cold and warm spheres. The sampling of water column, water-sediment interface and subsurface sediments will provide new information on climate variability of the past 25.000 years, related biogeochemical cycling and changes in the nutrient budget. In this context, element fluxes between the water-column and underlying sediments and fluid and/or gas leakages were of interest. Suitable locations for geological sampling of Holocene sediment sequences were identified by detailed sediment acoustic surveys along the shelf and upper slope of south-eastern Canada. The cruise is part of a bilateral collaboration in marine science between Dalhousie and Kiel Universities and GEOMAR Helmholtz Centre for Ocean Research Kiel.
