Chemical and biological sensor technologies have advanced rapidly in the past five years. Sensors that require low power and operate for multiple years are now available for oxygen, nitrate, and a variety of bio-optional properties that serve as proxies for important components of the carbon cycle (e.g., particulate organic carbon)....
The subarctic-subtropical transition zone in the North Pacific represents the second largest sink of
atmospheric carbon dioxide in the world ocean, yet the relative importance of physical and biological processes in
this uptake is debated. In a step toward understanding the spatiotemporal variability of environmental,
physiological, and ecological factors that...
We have used the vanadium concentration in cleaned foraminiferal calcite as a tracer
of seawater V changes in the past. Since the benthic flux of vanadium is sensitive to the redox potential
of sediments, changes in the vanadium concentration of seawater should be a reflection of
changes that control the...
