Ziel der Reise / Objectives of Cruise:

The goal of this project is to obtain accurate and well resolved hydrographic and current data and to combine these with seismic measurements acquired under the EU project GO to study the internal wave field and mixing processes in the Gulf of Cadiz. New methods to underpin the developing research field of seismic oceanography are being evaluated and improved an the basis of this data set. CTD/LADCP data have been collected contemporancously and at very close distance to marine seismic reflection measurements. The combination of the seismic data with its very high horizontal resolution of down to a few meters together with the more accurate hydrographic and current measurements will yield new understanding and insights into water mass mixing processes and will significantly further the new tool of seismic oceanography. In particular the comined data set will be used to investigate the mixing processes connected to meddies (subsurface eddies with water of Mediterrancan origin), which result in structures highly visible in seismic data. As described above, hydrographic and current data were measured with standard and state of the art physical oceanography tools on FS Poseidon. A good part of the cruise this was done following RRS Discovery which was underway doing seismic oceanography measurements for the EU profect GO.

Current profiler (e.g. ADCP)
Lowered ADCP profilies together with CTD profiles using two RDI workhorse systems no
IFMGEO Papenberg Cord 36 hour(s) G90
Other geological or geophysical measurements
At two locations a vertical seismic profiler, a string of hydrophones, was lowered from the stationary ship to listen continuously to seismic sound reflections Seismic sound was omitted by RRS Discovery which steamed in various patterns around FS Poseidon. Temporal veriations of the reflectivity and their email scale horizontal variations were thereby investigated. no
