A simple vertical advection-eddy diffusion model was applied to continuous vertical temperature, salinity, and dissolved oxygen profiles at depths greater than 1000 m in the eastern Caribbean. The continuous profiles were well-suited to vertical modeling because they tightly constrained the selection of the model boundaries and the model parameters. A model in which oxygen was assumed to be a conservative constituent fit the observations to within about 0.06 mll. The vertical advection-eddy diffusion parameter was the same at three locations in the Grenada Basin, but it was 50 smaller at the northeast corner of the Venezuela Basin. This analysis provides values for the upward vertical velocity for the vertical eddy diffusion coefficients, and a rate of oxygen consumption. A time of 350 years was calculated for the advection of waters between 2000 m and 1000 m in the eastern Caribbean.
