Gazette Article Featuring Dave Johnston’s Research

Please follow this link to a Harvard Gazette article “A Read on Seawater Sulfate” featuring the research of Dave Johnston’s group.  Quoting from the article “The ocean is often depicted as teeming with life, from crustaceans and fish to whales and other mammals, but in fact large swaths of it are virtual deserts, populated only by bacteria and a handful of particularly hardy species.”  Along with graduate student Andy Masterson, Dave’s group has developed a new isotope tool that significantly advances the study of this phenomena and the role played by sulfates.  Nice work!
