The data were collected primarily on two areas: (1) NNW of the Capraia Island, were ancient deep sea corals were dredged from mounds and small reliefs and other research studies have been carried out by ISMAR-Bologna [Remia et al.(2003),Remia and Taviani(2005)]) and (2) nearby the ODAS-Italia 1 buoy. The survey was generally performed at the speed of 10 Kn, except during high seas, utilizing as much as possible transit time from one station to the other, as well as periods during mooring and buoy maintenance.
For quick production we were able to use the 'real-time' DTM (resolution 10m), after a filtering step using a ISMAR procedure, able to detect and clean outliers and high-frequency noise. A better, yet preliminary processing was made at ISMAR Bologna. We present here some results.
Figures 24 and 25 show the area of the mooring W and of the 'mounds' NNW of Capraia Island. The Side Scan Sonar data that were collected NNW of Capraia by the above cited previous ISMAR cruises, will be reprocessed for a better georeferencing using the above DTM.
Figures 26 and 27 present the bathymetry of the area around the ODAS buoy. Figure 28 shows the area of the mooring W of the ODAS buoy.
