New paper in press
Uchikawa et al. (in press) Sulfate and phosphate oxyanions alter B/Ca and d11B in inorganic calcite at constant pH: Crystallographic controls outweigh normal kinetic effects. Geochimica et Cosmochimica Acta.
~~~~~~~~~~~~~~~~~~ Current/Active Research ~~~~~~~~~~~~~~~~~~
Co-PI on "Carbonic acid dissociation and calcite solubility in seawater of non-standard major ion composition"
Lead PI on "Ground-truthing lithium paleo-proxies: Experimental study on the Li incorporation and isotope
fractionation during inorganic calcite and aragonite precipitation" Co-PI: Dr. RIchard Zeebe.
Lead PI on "Effects of sulfate on boron incorporation into calcite: Relevance and implications for
foraminiferal boron isotope and B/Ca paleo-proxies",
Collaborative Research with Dr. Noah Planavsky (Yale) and Dr. Donald Penman (Utah State).
