| Objectives | The tenth Atlantic Meridional Transect (AMT10) took place 12th April to 8th May 2000. There are three objectives of the AMT programme. 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 responses of, oceanic ecosystems and climate change. The second is to investigate the functional roles of biological particles and processes that influence ocean colour in ecosystem dynamics. The third is the algorithm development and validation of remotely sensed observations of ocean colour. During AMT10 the ship was constrained in her ability to maintain station in any but the lightest winds, and the weather conditions were not always favourable. Nevertheless, the cruise produced a near-continuous set of surface underway data, and 23 stations during which physical, biological and chemical properties of the euphotic zone (depths 0-250m) were sampled. |
