Description 
Summary

The dataset comprises hydrographic profiles (temperature, salinity, oxygen, fluorometer, transmissometer, irradiance) and along track measurements (bathymetry, surface meteorology, sea surface hydrography), with discrete measurements including water chemistry (organic and inorganic nutrients, particulate organic carbon and nitrogen, dissolved gases, trace metals), biology (phytoplankton, zooplankton, primary production, community respiration, chlorophyll, pigments) and atmospheric particulates (major ions, organics and trace metals). Data have been collected from meridional transects of the Atlantic Ocean (between the UK and the Falkland Islands, South Africa or South America) from 1995 to the present day. The Atlantic Meridional Transect (AMT) programme aims to study the factors determining the ecological and biogeochemical variability of planktonic ecosystems in the tropical and temperate Atlantic Ocean, and their links to atmospheric processes. The majority of the data are available to academia for re-use and re-purpose but data from recent cruises may be subject to a moratorium which allows first use for data originators. The AMT is coordinated by Andy Rees (AMT Principal Investigator) and Miss Dawn Ashby (AMT Project Officer) at the Plymouth Marine Laboratory (PML) in conjunction with the National Oceanography Centre. Since its inception the programme has involved researchers from several different countries and has acted as a platform for national and international collaboration. Data are managed by the British Oceanographic Data Centre.
