The annual AMT voyage undertakes biological, chemical and physical oceanographic research in the Atlantic Ocean
The transect crosses several ecosystems from sub-polar to tropical, euphotic shelf seas to oligotrophic mid-ocean gyres
AMT samples over a 100° latitude, including the rarely visited South Atlantic Gyre
Consistent observations are made on the biogeochemical properties of plankton ecosystems
Data sets include: CTD Profiles and water sample measurements of nutrients, pigments, dissolved gases and particulate carbon and nitrogen
Over 223 scientists from 18 countries have generated more than 220 refereed publications and contributed to over 70 PhD Theses
AMT cruise data will help provide warning of any fundamental change in Atlantic ecosystem function, resulting in improved forecasts of the ocean's future state and related socio-economic impacts.

The Atlantic Meridional Transect (AMT) is a multidisciplinary programme which undertakes biological, chemical and physical oceanographic research during an annual voyage between the UK and destinations in the South Atlantic. The programme was established in 1995 and since then has included 23 research cruises involving 223 scientists from 18 countries. AMT has proved to be a long-term multidisciplinary ocean observation programme, which is a platform for national and international scientific collaboration, a training arena for the next generation of oceanographers and an ideal facility for validation of novel technology.

 

The AMT programme has been crucial for the training of many European young researchers at the postgraduate and postdoctoral level.
