Gear construction: Double-sided, D-shaped runners and a net with a mesh size of 1 cm
Dimensions: 8.7 x 3.5 x 0.7 m
Weight: ~ 200 kg
Deployment: On the R/V Sonne the AGT is deployed over the starboard side and the winch pulls the gear over a section of the seafloor.
Maximum Depth: Full Ocean Depth
Follow-up work: To preserve the animals from the trawl, the mud is carefully sieved through a series of decreasing size sieves: 1 mm – 500 μm. All specimens are picked out as quickly as possible and preserved for further studies. We photograph some of the specimens before preservation to document their live colors and shape.
Samples / Results: Qualitative samples of the benthic mega-epifauna, as well as some of the infauna and bentho-pelagic fauna.
