About AMT

The main deliverable of AMT is a unique time series (1995-2012) of spatially extensive and internally consistent observations on the structure and biogeochemical properties of planktonic ecosystems in the Atlantic Ocean that are required to validate models addressing questions related to the global carbon cycle.

Data sets include:

  • Vertical CTD profiles and continuous underway data
  • Optical characteristics of the water column
  • Biogeochemical measurements on water samples including nutrients, pigments, dissolved gases and particulate carbon and nitrogen
  • Primary, new production and respiration measurements

The programme is coordinated and led by Plymouth Marine Laboratory in collaboration with the National Oceanography Centre and is now funded by the Natural Environment Research Council's National Capability, having previously received funding through NERC's Oceans 2025 programme as a Sustained Observatory within Theme 10 (which secured the continuation of these measurements along the transect for 5 cruises between 2008 to 2012.)


Since 1995 AMT has been scientifically led and coordinated by the Plymouth Marine Laboratory. This has involved a total of 23 research cruises with 223 scientists from 18 countries, over 200 refereed publications and 70 PhD theses. AMT continues to contribute to science and policy development including the social and economic understanding of the marine environment and services it delivers.
