PurposeResearch
ObjectivesThe focus of METEOR cruise M81/1 will be chemical and isotopic investigations of the distribution of dissolved and particulate trace metals and their isotopes (TEIs) in the tropical Atlantic Ocean. The main scientific goal of the cruise is the determination of the detailed full water column distribution of the TEIs on a NE-SW section from the Canaries to the deep Brazil Basin and further along the northern coast of South America in relationship to ocean circulation and the biogeochemical cycles. It is planned to investigate the influence of the main water masses of the Atlantic Meriodional Overturning Circulation (AMOC), as well as the east-west directed deep (Romanche Fracture Zone) and shallow exchange pathways between the western and eastern Atlantic Basins on the distribution of the TEIs. The influence of external sources such as the exchange with volcanic islands (Canaries) and Saharan dust will be a focus of the investigations in the upper water column. In addition, the influence of riverine inputs from the Amazon and Orinoco rivers at the surface, as well as the underlying water layers will be addressed. The influence of biogenic particle flux and the near equatorial oxygen minimum zone on the TEI distribution will be investigated along the cruise track, whereby sampling for 234Th and trace metal clean sampling for novel isotopic tracers such as Fe- and Cd-isotopes, as well as Si-isotopes, will be the main goal. Samples for all core parameters of the GEOTRACES program will be taken. Further foci will be sampling for radiogenic Hf-isotopes and REE concentrations and 232Th, which are weathering and circulation tracers complementary to core parameter Nd isotopes. The biogeochemical cycling of Se/Te, Nb/Ta, Zr/Hf, Mo/W and their speciation will be investigated. In addition, sampling for natural (227Ac, 226Ra, 228Ra) and anthropogenic radionuclides, such as 239,240Pu, 237Np and 137Cs isotopes will be performed.
