The Atlantic Meridional Transect - AMT

a multidisciplinary programme which undertakes biological, chemical and physical oceanographic research during a voyage between the UK and destinations in the South Atlantic.

Over 25 years of unique scientific excellence

AMT is a well respected and established scientific research programme which enables scientists to make open ocean observations through a wide latitudinal degree (100°), including the (rarely sampled) north and south Atlantic gyres. The cruise is unique and facilitates a greater understanding of the ocean and the biogeochemistry within it.

AMT30 Team

A significant contribution to oceanographic data

The AMT cruises have hosted over 250 scientists (from more than 60 research institutes in over 20 countries), produced over 300 significant scientific papers and contributed to over 100 PhD studies. It serves as an ideal 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.
