Caption

In order to determine the quantitative role of Trichodesmium in the phosphorus cycle, cells were incubated in bottles containing trace quantities of radioactive phosphate. University of Southampton graduate student Despo Polyviou (left) and Columbia University postdoctoral investigator Monica Rouco, place the bottles in a large container that is designed to mimic the light and temperature of the surface ocean. The container also ensure that the bottles, and the radioactivity they contain, never fall into the ocean.
