High-Frequency Dynamics of Ocean pH: A Multi-Ecosystem Comparison
The effect of Ocean Acidification (OA) on marine biota is quasi-predictable at best. While perturbation studies, in the form of incubations under elevated pCO2, reveal sensitivities and responses ofExpand

Atmospheric iron deposition: global distribution, variability, and human perturbations.
Atmospheric inputs of iron to the open ocean are hypothesized to modulate ocean biogeochemistry. This review presents an integration of available observations of atmospheric iron and iron deposition,Expand

Early Cenozoic decoupling of the global carbon and sulfur cycles
[1] Changes in carbon and sulfur cycling over geologic time may have caused considerable modification of atmospheric and oceanic composition and climate. Here we calculate pyrite sulfur (Spy) andExpand

Toxicity of atmospheric aerosols on marine phytoplankton
Atmospheric aerosol deposition is an important source of nutrients and trace metals to the open ocean that can enhance ocean productivity and carbon sequestration and thus influence atmosphericExpand

The oceanic phosphorus cycle.
Phosphorus (P) is an essential element to all life, being a structural and functional component of all organisms.1-4 P provides the phosphate-ester backbone of DNA and RNA, and it is crucial in theExpand

Origin of marine barite deposits: Sr and S isotope characterization
Barite can precipitate in microenvironments in the water column (marine barite), from supersaturated pore fluids at the oxic-anoxic boundary within marine sediments and where Ba-rich pore fluids areExpand

Nitrogen sources and cycling in the San Francisco Bay estuary: A nitrate dual isotopic composition approach
We used the dual isotopic composition of nitrate (δ15N and δ18O) within the estuarine system of San Francisco (SF) Bay, California, to explore the utility of this approach for tracing sources andExpand

A precise method for the analysis of δ18O of dissolved inorganic phosphate in seawater
A method for preparation and analysis of the oxygen isotope composition (δ18O) of dissolved inorganic phosphate (DIP) has been developed and preliminary results for water samples from variousExpand

Seasonality of N2 fixation and nifH gene diversity in the Gulf of Aqaba (Red Sea)
Nitrogen (N2) fixation rates were determined on bulk water collected in the Gulf of Aqaba, Red Sea, during fall (stratified, oligotrophic) and spring (deep mixing, mesotrophic) seasons. N2 fixationExpand
