The recent publication by SoMAS alum Shaily Rahman (PhD, 2016) and her advisors, Robert Aller and J. Kirk Cochran: “The Missing Silica Sink: Revisiting the Marine Sedimentary Si Cycle Using Cosmogenic 32Si” published in Global Biogeochemical Cycles 31, 1559 – 1578, is the January 2018 Research Spotlight on the American Geophysical Union site Eos.org.
In the Spotlight, author Terri Cook highlights how the team developed new techniques that more accurately, “by a factor of 2-4,” measure the “the amount and type of biogenic silica stored in samples collected from four depositional settings, including subtropical and tropical deltas and temperate coastal zones.”
