1. MERIDIONAL TRANSECTS
AIMS
Examine the latitudinal evolution of tracers following deep and intermediate water masses (e.g. Western Boundary Current, North Atlantic Deep Water, AAIW, AABW).
2. Provide linkage between other sections for oceanographic consistency.
Proposed work
4 NIOZ cruises in the north and south western basins
(proposed by Hein de Baar).
These will be high resoluton (1 degree resolution).
2. 1 UK lead cruise (high resolution transect).
Challenges
need strong hypothesis for funding
Th only basinscale sections- optimise sampling resolution carefully

5. SW Atlantic Meridional Justifications
Examine the latitudinal evolution of tracers following deep and intermediate water masses (e.g. Western Boundary Current, North Atlantic Deep Water, AAIW, AABW).
entrance of Southern Ocean water masses (AAIW, AABW) into the western Atlantic Basin (connects to Drake cruise), entrance of NADW to Southern Ocean
far field effects of dust input, margin inputs, comparison of seawater signal to observations at the margins
