Underway Surface Measurements
All data sets from the 1995-2005 cruises are publically available online under 'data delivery' at the BODC website. The remaining AMT data sets are available upon request to BODC, with future web delivery under development.
The Oceans 2025 data policy has been designed to make the data from the AMT cruises since 2007 available to the Oceans 2025 community one year after a cruise and then, after two years, to the wider scientific community. The aim being to make maximum use of this valuable data resource.
The British Oceanographic Data Center (BODC) has been integrating the data that resulted from the physical, chemical and biological measurements made during the first phase of AMT to answer the key AMT objectives:
- How does the structure, function, and flow of food within planktonic ecosystems vary in space and time?
- How do physical processes affect the supply of nutrients, including dissolved organic matters, to the planktonic ecosystem?
- How do ocean-atmosphere exchanges and sunlight affect the formation and breakdown of organic matter?
- During the second phase of AMT work expanded to cross-disciplinary studies of ocean plankton ecology and biogeochemistry, and link to atmospheric processes.
The location of the AMT transect allows for a basin-wide perspective on these cross-disciplinary measurements made during the cruises, providing integrated knowledge of the physical, chemical and biological behaviour of both the north and south Atlantic.
The expanded data sets collected during the AMT cruises between 2002 and 2006 include:
- Aerosol and rainwater composition
- Surface water time series and profiles of biological chemical and physical parameters
- Optical characteristics of the water column
- Primary, new production and respiration measurements
- Satellite imagery
- Plankton community structure
