Iron (Fe) is an essential micronutrient for marine phytoplankton often limiting phytoplankton growth due to its low concentration in the ocean and thus playing a role in modulating the ocean's biological pump. In order to ...
Subduction dynamics at the middle America trench : new constraints from swath bathymetry, multichannel seismic data, and ¹⁰Be
(Massachusetts Institute of Technology, 2003)
The cosmogenic radionuclide ¹⁰Be is a unique tracer of shallow sediment subduction in volcanic arcs. The range in ¹⁰Be enrichment in the Central American Volcanic Arc between Guatemala and Costa Rica is not controlled by ...
