The animations below show
the penetration of a dye tracer in the ocean.
The surface boundary condition for the tracer is a unit step function
in time. In steady state, the dye concentration everywhere will be "1".
As the simulations show, it takes several hundred to many
thousands of years to reach equilibrium. Simulations were performed
with the transport matrix method
using monthly mean transport matrices derived from the data-assimilated
ECCO (iteration 277) model.
