ObjectivesThe Atlantic Meridional Transects (AMTs) were conceived as a means of acquiring a time series of oceanographic, biological, chemical and optical data over large latitudinal ranges (50° N to 50° S) and through a number of contrasting oceanographic provinces. The core scientific objectives are to refine out understanding of the role of the ocean biota in the biogeochemical processes, carbon fluxes and ultimately global climate and to develop remotely-sensed measurements of global primary production.

The AMTs take advantage of the twice yearly passage of the NERC vessel, RRS James Clark Ross, operated by the British Antarctic Survey, during its passage to and from Antarctica each year. Since the only ship costs involved are to cover the additional time required for course deviations and station work, the AMT is a highly cost-effective project for fundamental marine science. AMT-3 is the third Atlantic transect in the current series.

Aims:
1. To improve our undestanding of the relationship between physical processes and biological production.
2. Identify, define and quantify latitudinal changes in biogeochemical provinces.
3. Determine phytoplankton characteristics and photosynthetic parameters.
4. Identify nutrient regimes and their role in biogeochemical cycles.
5. Characterise plankton community structure, including the accurate determination of carbon values
6. Relate the partial pressure of CO2 (pCO2) in surface waters with the biological production
7. Acquire data for the calibration of remotely sensed obersvations (primary validation).
