Scientific drivers for the work

The main objectives of the cruise are to map the distribution of trace elements and isotopes along the mid Atlantic ridge south of the Azores and in particular focus on the processes that govern the size and scale of signals linked to different types of hydrothermal vent site. In addition, via around 35 full water column profiles we can assess how variations in ridge driven mixing may affect the horizontal and vertical mixing of tracers in this region.
