| Summary of measurements |
- -Sidescan sonar: 7 zones each covered by a 3 NM profile at 100 m and a 1 NM profile 50 m depth.
-Shipeck grab sampling on 7 zones (from 1 to 5 samples per zone).
-Towed video on 7 zones for 10 minutes.
-CTD profiles at 4 points (from 3 to 6 profiles per point).
-Niskin bottle profiles at 4 points at 3 depths (from 3 to 6 profiles per point).
-Velocity time series (ADV and ADCP), suspended matter load (OBS, ADCP and Cilas granulometer), suspended matter granulometry (Cilas device), chlorophyll a loading (fluorimeter) at 4 points during 6 to 18 hours.
-Video imaging of a sediment cross-section (DySPI: Dynamic Sediment Profile Imagery) at 4 points, with 1 hour of sequential acquisition per point.
-Strata of 2 cm of sediment were sampled down to a maximum 20 cm depth at points, between 2 and 4 stratigraphic samples per point.
-2 drifting buoys were deployed: drifting for 14 days.
