The first GSR Nodule Exploration campaign was conducted from 24/07/2014 to 18/09/2014 in the GSR concession. The cruise focused on the acquisition of a complete (77,000 sq. kilometer) and detailed mapping of the seabed topography of the GSR concession, from 4300m to 5000m of water depth, by using multibeam echosounder (MBES) equipment built under the exploration vessel. The topographic information, together with the acquisition of the backscatter signal of the seabed and the collection of sediment and nodule samples, was used to “filter” the GSR concession and identify potential nodule fields. http://eu-midas.net/sites/default/files/newsletters/MIDAS_Newsletter_Aug2015_LO
