|A new gravity grab for quantitative sampling of the benthic fauna of water-bearing wells is presented. |
Because of its working principle, the device is similar to corers and to Ekman grabs, but it also shows remarkable features, discussed below.
The grab has been tested in a well along the Adriatic coast in the district of Chieti (Abruzzo, central Italy), where samples of sediment have been taken. Preliminary results of the survey are discussed.
