ObjectivesThe Atlantic Meridional Transect (AMT) Program exploits the passage of the Royal Research Ship (RRS) James Clark Ross (JCR) latitudinally through the Atlantic Ocean between the United Kingdom and the Falkland Islands (approximately 52° N to 52° S) in support of British Antarctic Survey (BAS) research activities in the Antarctic and its environs. In September, the JCR sails southward, sampling the boreal fall and the austral spring; the following April it returns to the UK sampling the austral fall and the boreal spring.

There are three objectives of the AMT Program. The first is to derive an improved understanding of the links between biogeochemical processes, biogenic gas exchange, air-sea interactions, and the effects on, and the responses of, oceanic ecosystems to climate change. The second is to investigate the functional roles of biological particles and processes that influence ocean colour in ecosystem dynamics. The Program relates directly to algorithm development and the validation of remotely-sensed observations of ocean colour. Because the Sea-viewing Wide-Field-of-view Sensor (SeaWiFS) instrument achieved operational status during the cruise (on 18th September). AMT-5 was designated the SeaWiFS data during the first 100 days of operations. This third objective involved in the near-real time reporting of in situ light and prigment obersvations to the Sea WiFS Project, so the performance of the satellite sensor could be determined.
