The Atlantic Meridional Transect (AMT) is a multi-disciplinary programme which originated undertaking biological, chemical and physical oceanographic research during the annual return passage of the UK research ship RRS James Clark Ross from the UK to the Falkland Islands in September and from the Falklands to the UK in May during the period 1995-2005. The project now operates under the Oceans 2025 programme as a Sustained Observatory and consists of an annual cruise in October/November from the UK to Punta Arenas in Chile. The transect repeated each year spans a distance of almost 13,500 km through many different ocean provinces.
