Journal ArticleDOI
Authigenic molybdenum formation in marine sediments: A link to pore water sulfide in the Santa Barbara Basin
Yan Zheng,Yan Zheng,Yan Zheng,Robert F. Anderson,Robert F. Anderson,Alexander van Geen,James S. Kuwabara +6 more
TL;DR: Pore water and sediment Mo concentrations were measured in a suite of multicores collected at four sites along the northeastern flank of the Santa Barbara Basin to examine the connection between authigenic Mo formation and pore water sulfide concentration.
Journal ArticleDOI
Influence of plankton mercury dynamics and trophic pathways on mercury concentrations of top predator fish of a mining-impacted reservoir
A. Robin Stewart,Michael K. Saiki,James S. Kuwabara,Charles N. Alpers,Mark Marvin-DiPasquale,David P. Krabbenhoft +5 more
TL;DR: In this article, changes in the quality and quantity of suspended particulate material, zooplankton taxonomy, and MeHg concentrations coincident with seasonal changes in water storage of a mining-impacted reservoir in northern California, USA.
Journal ArticleDOI
Trace metal associations in the water column of South San Francisco Bay, California
TL;DR: In this paper, the spatial distribution of copper (Cu), zinc (Zn) and cadmium (Cd) were followed along a longitudinal gradient of dissolved organic carbon (DOC) in South San Francisco Bay (herein referred to as the South Bay).
Journal ArticleDOI
Biological effects of anthropogenic contaminants in the San Francisco Estuary.
Bruce Thompson,Terry Adelsbach,Cynthia L. Brown,Jennifer A. Hunt,James S. Kuwabara,Jennifer C. C. Neale,Harry Ohlendorf,Steve Schwarzbach,Robert Spies,K. Taberski +9 more
TL;DR: The studies summarized provide a body of evidence that some contaminants are causing biological impacts in some biological resources in the Estuary, however, no general patterns of effects were apparent in space and time, and no single contaminant was consistently related to effects among the biota considered.
Journal ArticleDOI
Mercury speciation in piscivorous fish from mining-impacted reservoirs
TL;DR: Results of XANES analysis clearly indicated that mercury accumulated in these individual fish from the two reservoirs were dominated by methylmercury cysteine complexes, consistent with results from commercial fish species inhabiting marine environments which are presumed to include differing mercury sources.
