Virginia Key, Fla. The University of Miami's Rosenstiel School of Marine and Atmospheric Science announced today that it has selected Rosalind E.M. Rickaby, Ph.D., as recipient of the 2009 Rosenstiel Award. A university lecturer in Biogeochemistry and a Tutorial Fellow of Wolfson College, Rickaby works in the Department of Earth Sciences at the University of Oxford. Her current research on the interaction between marine phytoplankton and dissolved carbon dioxide in the oceans is helping to establish a critically important record of the influences these microorganisms have had on the Earth's climate.
The Rosenstiel Award honors scientists who, in the past decade, have made significant and growing impacts in their field. It is an award targeted for researchers that are already making outstanding scientific contributions in their early to mid-career stages.
Rickaby's innovative approach to the measuring changes in atmospheric pCO2 levels during the Cenozoic suggests that direct climate signals of the past are harbored within, and can ultimately be deciphered from, the genetic make-up of existing organisms like marine algae. Her proposed studies are helping to gather extensive and necessary information on the history of pCO2, while also yielding additional insight into the feedback between phytoplankton and climate, the carbon isotopic signatures of the geological record and the mechanistic link between the amino acid sequence and specificity of RUBISCO (an important enzyme in the transfer of inorganic carbon into the biosphere) with a view to enhanced crop photosynthetic efficiency.
In her research she has also devised an ingenious solution to examine the oxygen isotopic composition of the water in certain hydrated carbonate minerals, such as Ikaite. With this technique scientists will be able to ascertain precise changes in the oxygen isotopic composition of seawater in areas where Ikaite forms, which are critical to understandi
