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.

Much of his graduate work was conducted in the Sargasso Sea in conjunction with the Bermuda Atlantic Time-series Study (BATS) site. He moved to the Bermuda Institute for Ocean Science (BIOS) in for his post doctoral work where he focused on the focused on the biogeochemistry of dissolved organic matter in the oceanic systems of the. Complexation of cobalt by natural organic ligands in the Sargasso Sea as determined by a new high-sensitivity electrochemical cobalt speciation method suitable for open ocean work. Marine Chemistry , 75 (), DOI: /S(01) Andrzej Bobrowski, Jerzy by: The Sargasso Sea, particularly in the region of the BATS site, is perhaps the most intensively studied region of the world's ocean in terms of carbon and nitrogen biogeochemistry (Steinberg et al Cited by: Biogeochemistry.

Cobalt By John F. Slack, Bryn E. Kimball, and Kim B. Shedd Chapter F of Critical Mineral Resources of the United States—Economic and Environmental Geology and Prospects for Future Supply. Seawater samples must be UV-irradiated prior to analysis, in order to liberate organically-bound Co. A field study in the Sargasso Sea, demonstrated that aerosol Co was significantly more soluble than aerosol Fe over a range of aerosol dust deposition fluxes (1– μg Fe m-2 d-1) (% for Co versus % for Fe).Author: Rachel Shelley. This thesis explores the potential of zinc, cobalt, and phosphorus to influence primary production in the subarctic North Pacific, the Bering Sea, and the North Atlantic Ocean. In the North Pacific and Bering Sea, total zinc concentrations were measured along a near-surface transect and in . Biogeochemistry of Marine Dissolved Organic Matter, Second Edition, is an extremely useful resource that helps people interested in the largest pool of active carbon on the planet (DOC) get a firm grounding on the general paradigms and many of the relevant references on this : $
