“…Dissolved Ni exhibits a nutrient-type distribution in the oceans and its concentration ranges from 2 to 12 nM (Sclater et al 1976;Bruland 1980). Price and Morel (199 1) have provided evidence indicating a potential biochemical role for Ni in urea assimilation by marine phytoplankton.…”

Interactive influences of bioactive trace metals on biological production in oceanic waters

We present an overview of the oceanic chemistries of the bioactive trace metals, Mn, Fe, Co, Ni, Cu, and Zn; we combine field data with results from laboratory phytoplankton culture-trace metal studies and speculate on the potential influences of these trace metals on oceanic plankton production and species composition. Most field studies have focused on the effects of single metals. However, we propose that synergistic and antagonistic interactions between multiple trace metals could be very important in the oceans. Trace metal antagonisms that may prove particularly important are those between Cu and the potential biolimiting metals Fe, Mn, and Zn. These antagonistic interactions could have the greatest influence on biological productivity in areas of the open ocean isolated from terrestrial inputs, such as the remote high nutrient regions of the Pacific and Antarctic Oceans. The emerging picture of trace metal-biota interactions in these oceanic areas is one in which biology strongly influences distribution and chemical speciation of all these bioactive trace metals. It also seems likely that many of these bioactive trace metals and their speciation may influence levels of primary productivity, species composition, and trophic structure. Future investigations should give more complete consideration to the interactive effects of biologically important trace metals.Biological processes can strongly influence the oceanic chemistries of trace metals, and, in turn, trace metals can influence plankton production and community structure. These interactive influences are particularly important for six metals of the first transition series which are required by phytoplankton for various metabolic functions: Mn, Fe, Co, Ni, Cu, and Zn. A deficiency of these "bioactive" trace metals may limit oceanic plankton production (Brand et al. 198 3), and an excess of certain of these same metals may inhibit plankton growth (Brand et al. 1986; Sunda 1988 Sunda -1989.Our knowledge of the oceanic concentrations, distributions, and cycles of trace metals has advanced significantly (see Bruland 1983; Whitfield and Turner 1987). We now know the bioactive trace metals exist at nanomolar (1 Om9 M) to picomolar ( lo-l2 M) concentrations in oceanic waters. In addition, marine chemists have recently advanced their ability to characterize the chemical speciation of these bioactive trace metals in the sea; that is, we can now determine their free ion concentrations and the extent to which certain trace metals interact with organic and inorganic ligands naturally present in oceanic surface waters. Results from laboratory studies on the relationship between dissolved trace metal concentrations and phytoplankton growth have emphasized the importance of the chemical speciation of trace metals in the external milieu of these organisms (Huntsman and Sunda 1980; Morel and MorelLaurens 1983; Sunda 1988 Sunda -1989.As a result of these advances, we now realize that the concentrations of the bioactive metals are much lower and that chemical...

Nickel, cadmium, and copper in the northeast Pacific off the coast of Washington1,2

The distributions of nickel, cadmium, and copper have been determined in northeast Pacific waters off the coast of Washington. Nickel concentrations average 5.5 nmol.kg-l at the surface and 10 nmol.kg-L in deep water. Although nickel shows a dual covariance with phosphate and dissolved silicon, a strong concentration gradient away from the coast cannot be explained by variations in the nutrient concentrations alone; an additional source in the sediments is suggested. The geochemistry of cadmium is controlled by the biological cycling of organic matter. Concentrations are depleted to levels of 0.1 nmol.kg-l at the surface but increase to a maximum of 1.27 nmolakg-l at the depth of the phosphate and nitrate maxima. Cd-phosphate and Cd-nitrate correlations are significantly different in nearshore and offshore waters. Copper shows no correlation with the nutrients. An apparent surface maximum may result from the upwelling and offshore advection of Cu-rich shelf water. Copper is rapidly stripped from subsurface waters but is then returned to bottom waters via a flux of dissolved copper from the sediments.
