The Atlantic Meridional Transect (AMT) is a multi-disciplinary programme which originated to undertake 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. Between 2007 and 2012 AMT was funded within  the Oceans 2025 programme as a Sustained Observatory which consisted of an annual cruise in October/November from the UK to Punta Arenas in Chile. Since 2013 the AMT programme has been supported as a component of the UKs marine science National Capability (NC). The transect repeated each year spans a distance of almost 13,500 km through many different ocean provinces.
