Radium 228 as a tracer of basin wide processes in the Abyssal Ocean
- 1. Geophysical Fluid Dynamics Program, Princeton University, Princeton, New Jersey 08540
Description
A simple model of isopycnal mixing in a circular basin is developed in order to examine the utility of the 5.75-year half-life tracer radium 228 for studying basin wide processes in the deep ocean. The model shows that it is possible to resolve diffusivities of < or approx. =8 x 107 cm2 s-1 in a basin of approx.3000-km diameter with profiles measured near the center and edge of the basin. A least squares fit of the model to four abyssal profiles measured during GEOSECS in the North American Basin gives an isopycnal diffusivity of 6 x 107 cm2 s-1
