    Caroline Alexa Famiglietti

    Ph.D. Student in Earth System Science

    BioCaroline Famiglietti is a second-year PhD student working with Prof. Alexandra Konings. She is interested in using remote sensing technologies to assess large-scale interactions between the carbon and water cycles. In 2017, Caroline graduated summa cum laude from UCLA with a B.S. in Applied Mathematics and a minor in Geography/Environmental Studies. Prior to graduate school, Caroline worked in the Carbon Cycle & Ecosystems group at NASA JPL (with Josh Fisher) from 2017-2018 and in the UC Berkeley Department of Civil & Environmental Engineering (with Sally Thompson) in 2016.

    BioAntarctic ice sheet, both of which have exhibited significant mass loss over the past few decades. If the two ice sheets were to fully collapse, they could be responsible for up to 15m of global sea level rise (roughly equal parts from both). This sea level rise would not only pose serious problems for coastal settlements, but cause serious changes to ecosystems, and could profoundly alter the Earth’s ocean circulation.

    Current estimates of the mass balance for ice sheets are based primarily on satellite data. This data has become more accurate and more available than ever before, since the 1990s. While estimates can be provided by satellite data, satellites are limited by virtue of the fact that they can only evaluate the surface of the ice shelf. Recent research has shown that a significant amount of the mass loss from the West Antarctic ice sheet is happening underwater, along grounding lines, where deep waters, warmed by global warming, enter the area underneath the ice shelf, and melt the shelves from the bottom. This not only results in mass loss directly, but increases calving of glaciers into the ocean, further accelerating their loss. This melting, below the surface of the ice shelves, cannot be estimated by satellites.

    To get a better understanding of the impact of warmer deep waters on glacial retreat in Western Antarctica, we need to measure the melt more directly. Using highly precise measurements of salinity and isotopic composition of seawater in coastal regions of Western Antarctica, we can estimate the amount of glacial meltwater present in the oceanic adjacent to ice sheets. Gaining a greater understanding of the rates and locations of West Antarctic melting will be crucial to developing our understanding of future sea level rise, and other wider impacts.

  • Nataniel Moishe Holtzman

    Nataniel Moishe Holtzman

    Ph.D. Student in Earth System Science

    BioNatan Holtzman is a first-year PhD student in the Earth System Science department working with Prof. Alexandra Konings. He is interested in using remote sensing and modeling to study how water moves between the atmosphere, plants, and soil. Natan graduated from the University of North Carolina at Chapel Hill in 2016 with a B.S. with honors in Geological Sciences and minors in Mathematics and Biology. From 2017 to 2018, he worked as a research associate at UNC with Prof. Tamlin Pavelsky on improving the representation of snowmelt-driven runoff in a regional climate and land surface model.

  • Elizabeth Johnston

    Elizabeth Johnston

    Ph.D. Student in Earth System Science

    BioAs a PhD Student in the Department of Earth System Science, Elizabeth investigates the response of Earth surface processes to climate. She is interested in coupling high resolution satellite imagery, field observations, and/or geochemical data with empirical models to answer research questions related to the response of landscapes and other surface processes to climate change. She is currently conducting research that examines the relative impacts of antecedent rainfall and urbanization on landslides using a data-driven statistical learning approach.

  • Bennett Kapili

    Bennett Kapili

    Ph.D. Student in Earth System Science

    BioBennett Kapili is a Ph.D. student in the Dekas Laboratory. He is interested in studying the microbial ecology and biogeochemistry of environments that push the limits of life. Through developing our understanding of how microbes function in extreme environments, he seeks to advance our search for life within our solar system. He holds a BS in Science of Earth Systems from Cornell University.
