RESEARCH INTERESTS:

SELECTED RESEARCH EXPERIENCE:

Gakkel Ridge research project: Bryn Mawr College, Bryn Mawr, PA (NSF-ARN proposal declined)

   Following pilot analyses of six Eastern Volcanic Zone basalts from the 85ºE volcano on the Gakkel Ridge, worked with collaborators at WHOI and Univ. of Wyoming to develop a study to thoroughly characterize U-series systematics of basalts from the full Gakkel Ridge and explore melt generation, crustal accretion, and melt-rock reaction at the ultraslow-spreading mid-ocean ridge endmember. Although recently declined, the proposal development accelerated collaboration between Elkins and colleagues at other institutions interested in state-of-the-art marine science research and the pedagogy and mentorship of undergraduates.

Jan Mayen research project: Bryn Mawr College, PA, 2011-present (NSF-OCE 1061037, $140,000)

   After analysis of 238U-234U-230Th-226Ra and 235U-231Pa in several samples from the Eggvin Bank ridge segment as pilot study (Elkins et al., 2011), major questions were raised about volcanism in the Jan Mayen region: is the volcanism caused by a small hot spot, or is it generated by mantle convection anomalies and/or unusual mantle chemical compositions? Working with Bryn Mawr and Haverford students and colleagues at Univ. of Wyoming to conduct isotopic analyses of a newly compiled sample suite from Jan Mayen Island and the southernmost Mohns Ridge. High-resolution mapping and targeted concentrated sampling of the Eggvin Bank segment in July of 2012 led to additional characterization of the region and further geochemical analysis, all to explore the question above.

Melt modeling research project: Bryn Mawr College, Bryn Mawr, PA, 2009-2011

   Development and analysis of new, sophisticated melting models that consider various complexities of the melt process, including variations in melt productivity and trace element partitioning behavior during melting. Included supervision of an undergraduate senior thesis project.

Mid-ocean ridge basalt alteration project: Bryn Mawr College, Bryn Mawr, PA, 2009-2010

   Conducted electron probe microanalysis of young Kolbeinsey Ridge basaltic glasses to characterize the extent of chemical alteration by seawater on the rocks. Included supervision of summer undergraduate research.

Doctoral Research: Geology & Geophysics, Woods Hole Ocean. Inst.; Earth, Atmospheric, and Planetary Sciences Dept., Massachusetts Inst. of Technology, 2003-2009; Advisors: K.W.W. Sims, F.A. Frey

    Dissertation: Basalt Petrogenesis Beneath Slow- and Ultraslow-Spreading Arctic Mid-Ocean Ridges

   Conducted comprehensive study of U-series isotopes (238U-234U-230Th-226Ra-210Pb and 235U-231Pa) and radiogenic isotopes (Hf, Nd, Pb, Sr) in 40+ Arctic mid-ocean ridge basalts. Equipped new lab facility for U-series analysis. Used existing and developed new complex time-dependent melting models for comparison with analyzed data (Elkins et al., 2011; new manuscript in prep.). Conducted piston-cylinder experiments on partitioning of U and Th during melting of mantle garnet pyroxenite (Elkins et al., 2008).

Director, Summer Science Research Program for Undergraduates, Bryn Mawr College, 2009-2011

   Coordinated, ran, and successfully overhauled the Summer Science Research Program at the College, as funding sources and directing offices for the program were changing dramatically. The Program funds on-campus undergraduate internships to conduct research in the sciences under the mentorship of Bryn Mawr faculty. Includes awarding internships to qualified applicants, coordinating with department faculty and chairs to manage those internships, working with donors and donor managing staff, inviting distinguished scientific and alumnae speakers and panelists to campus, and hosting events and workshops.
