Ziel der Reise / Objectives of Cruise:
Poseidon cruise 346 was a multidisciplinary expedition (sedimentology, biology, oceanography) aiming at better understanding the complex sedimentary system of the upwelling zone off Mauritania. The shallow Banc d'Arguin in the North of Mauritania and the continental slope West of Nouakchott were studied in order to address three main, interrelated objectives: 1. The high-nutrient tropical carbonates of the Gulf d'Arguin 2. The siliciclastic sedimentary record of the Banc d'Arguin and Mauritanian outer shelf 3. The deep-water reefs along the continental slope. The sedimentary system of Banc d'Arguin is one of the rare examples in the modern world where high- nutrient yet warm waters host carbonate production. The siliciclastic record with sedimentation rates of up to 1 m per 1 ka allows for high-resolution paleoclimate reconstruction of the Late Holocene. The deep-water reefs are the southernmost known occurrence of such ecosystems in the Eastern North Atlantic. The aim is to decipher this complex sedimentary system and its climatic and oceanographic record. Our work is integrated in a larger study on high-nutrient tropical carbonates, Northwest African mud belts, and comprehensive EU- and DFG-funded deep-water reef work.
