Oxygen as a Quasi-Conservative Constituent in Deep Waters of the Eastern Caribbean.
Abstract
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 ml/l. 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.
