Oxygen isotope fractionation in phosphate during iron oxide-phosphate interaction

Lead Institution

University of Delaware

Principal Investigator

Deb Jaisi

Project type

Exploratory Research

Measurements of 18O/16O ratio of organic and inorganic PO4 in laboratory experiments have found that microbial metabolism of PO4 is accompanied by specific oxygen isotope fractionations. More…

Phosphorus cycling at mineral-water interface: role of mineral dissolution and transformation

Lead Institution

Yale University

Principal Investigator

Ruth Blake

Project type

Large-Scale EMSL Research

Phosphorous (P) is an essential but limiting nutrient for all live forms. Mineral bound PO4 is conditionally available to (micro)organisms depending on the mineral properties, type of bonding…

Is the mobilization of sedimentary phosphorus a key player for sustaining eutrophication in the Chesapeake Bay?

Lead Institution

University of Delaware

Principal Investigator

Deb Jaisi

Project type

Large-Scale EMSL Research

With the rise of coastal dead zones, oxygen-dependent feedback effects on phosphorus (P) cycling in coastal environments will play more important roles globally. Proposed research will employ…
