Submarine Channel Flow Dynamics – The Black Sea

2013

The Black Sea

Autosub 3

The primary aim of this expedition supported by the RV Pelagia sailing from Istanbul was to image the 3D structure of submarine flows passing through a rare example of an active submarine channel system in the Southeast Black Sea.

Mapping of the internal flow structure within and outside the channel was achieved using Autosub 3 supplemented by vessel-based, CTD profiling and a fixed CTD mooring in the proximal channel for the duration of the cruise. The Autosub 3 data provided the first observed field example of a subsurface hydraulic jump formed by a flow moving over a scour.
