Experimental determination of carbonate-associated sulfate dS in planktonic foraminifera shells

Understanding the coupling of oxygen, carbon, and sulfur cycles in the past is critical for reconstructing the history of biogeochemical cycles, paleoclimatic variations, and oceanic chemistry. The abundance of sulfur isotopes (dS) in sulfate from ancient marine carbonates, or carbonate-associated sulfate (CAS), is commonly used, along with other archives (mainly evaporites and barite), to esti...

Experimental Inhibition of Carbonate Precipitation by Sulfite Minerals

Introduction: Volcanic and hydrothermal supply of reducing gases to the early atmosphere of Mars likely surpassed the slow supply of oxidizing power from hydrogen escape to space, resulting in a neutral or mildly reducing atmosphere and in geochemical cycles that operated very differently than they do on the modern Earth. We have recently suggested that one such difference between the modern an...

Septicemia caused by DF-2.

Fatal septicemia due to an unidentified gram-negative rod developed in a 60-year-old alcoholic. Infection due to this organism has been reported only rarely in the medical literature. Like Pasturella multocida, this organism is related to dog bites, is gram negative, and is sensitive to penicillin.
