Near-bottom enhancement of particulate Al (in w/v units) would suggest bottom sediment resuspension, and such a mechanism could account for apparent local increases in the concentra- tions of Fe, Mn, and V at the base of the water column (Robertson, unpublished report). Such could also be extended to include enhancements in "solu- ble" contents—for example, the copper and lead of Table 19-2; , enhancements due to the presence of particulate material less than the nominal nm filter pore size (Burrell 1978). Fig. 19-21 illustrates the distribution of surface soluble (passing //m membrane) copper and gives data for near-bottom samples from within the 100-m shelf contour. The mean bottom-water copper concentration given in Table 19-2 is for this shelf suite. It has been argued (Heggie, 1980) that the shallow-water copper gradient (negative away from the benthic boundary into the column) may be attributable to a flux of, in this case, remobilized copper from the sediments.
