Deep silicate content as evidence of renewal processes in the Venezuela Basin, Caribbean Sea
Average dissolved silicate concentrations in waters deeper than 1400 m of the Venezuela Basin (Eastern Caribbean Sea) increase from 27.7 μm in the north to greater than 29.0 μm in the south. Standard deviations of these values (a measure of temporal heterogeneity) decline from 1.8 in the north to 1....
