Skidaway Institute faculty and students visit Paris for Goldschmidt Conference

Skidaway Institute was well represented at the Goldschmidt Conference in Paris in August. Jay Brandes, Julia Diaz, Cliff Buck and Sydney Plummer participated in the annual, international conference on geochemistry and related subjects, organized by the European Association of Geochemistry and the Geochemical Society.

Jay was a co-convener of the session: “Tracking carbon from source to sink in modern and ancient environments: the carbon cycle in coastal environments, stable carbon isotope systematics, and the role of photochemical reactions.” His fellow conveners were Jaime Toney, Christian Schröder, Anke Neumann, Songhu Yuan, Leanne Powers (former SkIO post doc), Ying Cui and Xiahong Feng.

Jay was the lead author on one poster presentation and co-author on another with Leanne Powers, Kevin Ryan, Aron Stubbins and Bill Miller.

“What Can Carbon Isotopes Tell Us About the Nature of Photo-Labile Dissolved Organic Carbon?” Jay Brandes, Kevin Ryan, Aron Stubbins & Leanne Powers

Moderate Dissolved Inorganic Carbon (DI13C) Isotope Enrichment (MoDIE) for Improved Evaluation of DIC Photochemical Production in Seawater
