The distribution of dissolved silica in the deep western
North Atlantic Ocean is presented. The potential temperature-dissolved silica relationship is compared with the potential
temperature salinity relationship in the North Atlantic Deep
Water. Geographical variations in the potential temperature-
dissolved silica relationship are discussed with particular
emphasis on the low silica signal of the Western Boundary
Undercurrent (WBUC). The WBUC is shown to have a significant
influence on the potential temperature-dissolved silica
relationship from the tail of the Grand Banks of Newfoundland
to Cape Hatteras.
It is suggested that a region of enhanced mixing is present
west of 65°W that is responsible for the observed changes
in the dissolved silica distribution.
