Si-32 availability

Los Alamos National Laboratory is once again producing the radioisotope
Silicon-32 with high specific activity suitable for studies of Si
cycling in the upper ocean. The isotope is available through the isotope
distribution office at Oak Ridge National Laboratory.  The contact
person for sales is Jeff Sheldon (sheltonjh@ornl.gov), (865) 574-6984.

Developments in recent years have greatly reduced the amount of Si-32
required in silica production experiments allowing this rather expensive
isotope to be cost effective in oceanographic work (Krause et al. 2011:
Mar. Chem. 127:40-47).  Those interested in implementing these methods
can contact Mark Brzezinski (mark.brzezinski@lifesci.ucsb.edu).
