  • Jan Seiler from Germany, receives the ROV, the autonomous submarine vehicle with a video camera as it comes out of the water
  • The bottom trawl catch is emptied directly into the wet laboratoty where it will be sorted
  • Iain Barratt, from UK, one of the octopus specialists, looking for some intact specimens in the higher part of the bottom trawl, shows a brittle-star and its enormous arms
  • Olaf, Gesche and other scientists in the big wet lab sorting the benthos (sea floor fauna) as the by-catch of the bottom trawl
  • For this particularly muddy Agassiz trawl, Meike Messner from Germany enters the net to already select the upper part of the catch, not too mixed, before the catch is poured on the deck
  • Christine, Thomas and Olaf throwing stones overboard caught by the Agassiz trawl
  • David Fischer from Germany bringing on deck a multicorer used to sample sediment... and the fauna inside
  • Armin Rose (Germany) and Maarten Raes (Belgium) slicing a sediment core to isolate meiobenthos bottom fauna with a size smaller than 1mm
  • The big weight (1 Ton) of the gravity corer allows it to penetrate much deeper in the sediment
  • Christine McClelland from Canada ready to put her giant box corer in the water, a gear adapted to retrieve big quantities of undisturbed sediment
  • Americo Montiel from Chile, on the right, controls his multi-box corer arriving at the bottom thanks to a video screen in the winch control room
  • Marzia Umani from Italy and Enrique Isla from Mexico pull their plankton net back on deck
  • After having been released from the weight of the piece of rail which remained on the sea-floor, the frame bearing the amphipod crustaceans traps is back on the surface
