Brewer, P.G., T. Takahashi, and R.T. Williams. 1986. Transient Tracers in the Oceans (TTO) - Hydrolographic data and carbon dioxide systems with revised carbon chemistry data. NDP-004/R1, Carbon Dioxide Information Center, Oak Ridge National Laboratory, Oak Ridge, Tennessee.
The 1981 TTO North Atlantic experiment cruise consisted of seven legs
and visited 250 hydrographic stations across the North Atlantic Ocean
in 200 days. About 9000 water samples were taken for analysis of
salinity, oxygen, and nutrients. More than 3000 samples were collected
for tritium analysis, and more than 1000 samples for radiocarbon
analysis. Samples were characterized hydrographically (e.g., sample
depth, ocean depth, and water temperature) and chemically (e.g.,
alkalinity, salinity, silicate concentrations, and nitrate concentrations).
They may be used for ocean-mixing studies, for testing models of ocean
CO2 uptake, and for determining the exchange of carbon dioxide
between the atmosphere and the ocean. The data are in two files [ origional
TTO data (0.67 MB) and revised TTO data (0.86 MB)].
Institutions participating in the TTO North Atlantic Experiment include:
Lamont-Doherty Geological Observatory, Columbia University, Princeton
University, Scripps Institution of Oceanography, University of California,
Rosenstiel School of Marine and Atmospheric Science, University of Miami,
and Woods Hole Oceanographic Institution.
The TTO North Atlantic Experiment was sponsored by the National Science
Foundation and the U.S. Department of Energy.
