    Biological processes in the oceans play a crucial role in regulating the fluxes of many important elements such as carbon, nitrogen, sulfur, oxygen, phosphorus, and silicon. As we come to the end of the 20th century, oceanographers have increasingly focussed on how these elements are cycled within. Lohan ). Nutrient-like depletion of cobalt has been observed in the upper water column of several environments including the Sargasso Sea, North Pacific, Costa Rica upwelling dome, and Peru upwelling region (Martin et al. , Saito and Moffett , Saito et al. , Saito et al. ). While cobalt generally behaves similarly to iron in.

      I first heard about the Sargasso Sea as a kid in Florida—I think I was 13—when reading William Beebe's book Half Mile Down. I was entranced with Missing: biogeochemistry  cobalt. Deborah K. Steinberg is an American Antarctic biological oceanographer who works on interdisciplinary oceanographic research programs. Steinberg's research focuses on the role that zooplankton play in marine food webs and the global carbon cycle, and how these small drifting animals are affected by changes in : Oceanography.

Cobalt and manganese uptake onto suspended particles was studied in waters collected from Waquoit Bay, Massachusetts and the upper water column of the Sargasso Sea using radiotracers, coupled with. The ligand Teta was explored as a means to induce cobalt limitation.

The CoTeta complex was not bioavailable to the Sargasso Sea microbial assemblage in short-term experiments. Bottle incubations with Teta did not induce cobalt limitation of by: 7.

Moreover, Mediterranean circulation prevented the exchanges between the DCo‐rich surface and the DCo‐poor deep layers enhancing the scavenged‐like profile of DCo.

Finally, tentative DCo budgets were balanced at basin scale and showed the strong imprint of the surface inputs at Gibraltar Strait on the Mediterranean cobalt by: 6. The biogeochemistry of cobalt in the Sargasso Sea By Mak A Saito Download PDF (13 MB)Author: Mak A Saito.

A highly sensitive voltametric technique was developed for the direct determination of cobalt and nickel in seawater at picomolar and nanomolar concentrations, respectively.

Cyclohexane-1,2-dione dioxime (nioxime) complexes of Co(II) and Ni(II) were concentrated from 10 mL of sample onto a hanging mercury drop electrode by controlled adsorption and the current resulting from reduction of Co(II.

The objective of this research project is to use electrochemical/analytical work, culture work, and field work to explore the biogeochemistry of cobalt in the Sargasso. Cobalt is an important micronutrient for marine phytoplankton, and it is part of several current hypothesis about the ecology and biogeochemistry of the oceans.
