Ziel der Reise / Objectives of Cruise:
Overall objectives in the POL science programme to 2007 include estimates of slope mixing and some of its oceanic effects. As part of this, objectives a) on the cruise were to make measurements to enable estimates of internal waves and their induced mixing and bottom boundary layer forms (over the West Shetland slope), and to enable the estimates to be related to context: slope, stratification, mean flow. In the wider project, further allied objectives are: b) to derive, using 3-D fine-resolution and specialist process models for extrapolation, an estimated effect on the characteristics of water flowing adjacent to slopes with (internal-wave-induced) mixing; c) to estimate, using 3-D fine-resolution models for extrapolation, the role slope mixing and associated processes such as water mass transformation, play in cross-slope exchange of mass, heat, salt and nutrients.
