What are the relative magnitudes of natural and anthropogenic nickel sources?

Nickel fluxes from benthic sediments can be quantified using core incubations according to established protocols. Additional work will be needed in the wetlands and marshes adjacent to San Pablo Bay to determine fluxes of nickel from those regions. This work is being incorporated in the Regional Monitoring Program (RMP) redesign.

  1. Are the high levels of dissolved nickel observed in western San Pablo Bay typical of other shallow embayments?

Our understanding of nickel gradients in western San Pablo Bay is limited to a single station at the mouth of the Petaluma River. Additional monitoring is needed to evaluate the spatial extent of the nickel gradient, and whether this gradient is typical of shallow embayments or related to unique features of San Pablo Bay. This work is being incorporated in the Regional Monitoring Program redesign.
