Ziel der Reise / Objectives of Cruise:
The major goal of this expedition was to get a better understanding in biogeochemical processes and community structure of the Atacama Trench system in highly productive surface waters. Detailed understanding of benthic biogeochemistry requires insight to the processes conveying sediment deposition, the nature of settling material, and the aerobic and anaerobic microbial-driven mineralization processes in the seafloor, all of which was explored during the cruise. Our studies addressed the ecosystem functions such as benthic respiration, remineralization and nutrient transport, bacterial productivity, microbial as well meio- and macrofauna biodiversity in the eutrophic Atacama Trench and adjacent abyssal and bathyal sediments.
