Iron regulation of ocean ecosystems
Project Manager/Lead Scientist: Ken Johnson
As in the past several years, the goals of this project are to extend our understanding of the role that iron plays in regulating ecosystem structure and the impact of iron on biogeochemical cycles and climate.
During 2004, we will continue the time series of measurements in Monterey Bay. These observations provide a picture of iron dynamics that is unparalleled anywhere else in the world.
Secondly, we will do three ROV dives in the Año Nuevo/Davenport region to finish that time-series study. The dives will take place in winter and spring, to overlap the time frame at which we began sampling.
Third, we will continue collecting iron samples with OsmoSamplers on additional moorings (M1, M2, MOOS). If problems are identified, we will work to eliminate these difficulties.
Finally, we have a proposal submitted to NSF (Collaborative Research: Sampling and Analysis of Iron (SAFE)) to conduct an international iron intercalibration exercise. (a separate abstract has been submitted for this project). If this proposal is funded, we will need to dedicate a significant level of effort to that work.
