2008 SHOTS Workshop
Southern Hemisphere Ocean Tracer Studies:Tracer studies using ocean circulation models
Jan. 30 - Feb. 1, 2008
Central Research Institute of Electric Power Industry
Transient chemical tracers such as 3H,3He, chlorofluorocarbons (CFCs), radiocarbon (14C), artificial radionuclides (137Cs, 239,240Pu) have been extensively used in oceanography to provide information on the pathways, mechanisms, and rates of ocean circulation. Global modeling studies for transient chemical tracers by ocean general circulation models are effective both to understand the mechanism of material transport in the ocean, and to assess the skills of ocean general circulation models in comparison with observational database. Extensive measurements of transient chemical tracers have been conducted throughout the world ocean in a number of programs, e.g., Transient Tracer in the Oceans Programme (TTO), the World Ocean Circulation Experiment (WOCE) and the Climate Variability and Predictability Experiment (CLIVAR).
Recently, our SHOTS (Southern Hemispheere Ocean Tracer Studies : Tracer studies) project provides an long-term database for ca. 50 years (HAM database) including artificial radionuclides (137Cs, 239,240Pu) and Southern Hemispheere Ocean transects of transient chemical traces such as artificial radionuclides.
Now we can choose many transient chemical tracers for the modeling studies.
The result of comparison of ocean circulation modeling with multi-tracers are expected to provide significant constrains to global modeling.
