Multidisciplinary studies of the sub-polar and tropical North Atlantic (Koordinatorantrag M 60)

• Applicant: Professor Dr. Douglas W.R. Wallace
• Subject Area: Oceanography
• Term: from 2003 to 2006
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 5413880

The proposed expedition is comprised of 5 legs covering the sub-tropical gyre of the North Atlantic from the Azores and Madeira to the tropical western Atlantic. Leg 1 focusses on the ecology and biogeochemistry of seamounts in the eastern Atlantic in the context of an EU program; Leg 2 compromises a detailed seismic and geophysical investigation of a propagating ridge segment at the Mid-Atlantic Ridge in cooperation with French scientists; Leg 3 is a multidisciplinary (geological, biological and chemical) investigation of the effects of hydrothermal cirulation at the Mid-Atlantic ridge in support of a DFG Special Priority Program; Leg 4 is a physical oceanographic study of long-term variation of the thermohaline circulation in the western basin of the Atlantic in the context of the BMBFCLIVAR progam; and Leg 5 is a multidisciplinary (chemical/biological) investigation of CO2 uptake and the biological pump in the water column of the North Atlantic sub-tropical gyre (DFG Special Research Area 460).
