My research projects focus on combining remotely-sensed and in situ observations and numerical ice flow modeling to develop a better understanding of the environmental triggering mechanisms and internal controls of marine-terminating glacier behavior (i.e., glacier dynamics). I am particularly interested in glacier-ocean interactions, namely submarine melting and iceberg calving, and how changes in these interactions influence the rate of mass loss from the fast-flowing glaciers that drain the Greenland and Antarctic ice sheets. I completed my Ph.D. research under the supervision of Dr. Ian Howat (Glacier Dynamics Group, Byrd Polar and Climate Research Center) in 2013. Since then, I have been working at the University of Maine Climate Change Institute. Information on my research interests can be found under the Research tab.
I am also actively involved in a number of outreach activities. I currently co-chair of the US national committee for the Association of Polar Early Career Scientists (USAPECS). USAPECS is in its infancy and looking for ways to engage our constituents so please contact me if you have ideas for webinars, online or in-person events, or panel discussions that you would like to have organized at conferences. I also enjoy giving presentations on glaciers and climate change to middle and high school students (see Outreach tab). If you're a teacher looking for a guest speaker, please contact me!
My undergraduate research assistant and UMaine junior, Caroline Carrigan, recently presented her research results on iceberg melting at the UMaine Center for Undergraduate Research symposium. This was Caroline's first scientific poster! She presented her preliminary results on submarine melting for icebergs calved from Alison Glacier in NW Greenland and Zachariae Isstrom in NE Greenland. She's found that 2011 iceberg melt rates were similar in both locations, with an average of ~0.04 m/d and no significant seasonal variations. She'll be expanding her datasets to investigate seasonal and inter-annual variations in iceberg submarine melting near these two glaciers during her senior year at UMaine.
