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. -
Samantha Hordyk
Masters Student in Geophysics, admitted Autumn 2022
BioI recently graduated from Reed College with a physics degree and am now pursing a Master's in Geophysics at Stanford University, advised by Prof. Jenny Suckale. My research interests lie in numerical modeling of environmental fluids, and the fundamental multi-phase physics of natural systems. In all my work, I am committed to creating a safer and more resilient world.

Stepfan Huntsman
Ph.D. Student in Geological Sciences, admitted Winter 2022
Research Collections Asst, Earth Specimen CollectionBioI've had an interest in rocks and fossils since I was a small child, amassing a large collection in my youth, but hadn't considered it a viable career path instead starting my path as a social scientist studying gender and sexuality. My interest in a career in paleontology peaked after finishing my first degree, leading me to pursue a second bachelors degree. While working on my undergraduate at Weber State I discovered a true deep love of plants as well as a curiosity about the methods they use to adapt to new environments, which has lead me to pursuing a doctoral degree here at Stanford University.

Amanda Jackson
Ph.D. Student in Geological Sciences, admitted Autumn 2022
BioI’ve long been fascinated with volcanoes, and my research interests broadly include igneous petrology, trans-crustal magmatic systems, high temperature geochemistry, and geo/thermochronology. My first PhD project explores the formation of Catalina Island and investigates pluton assembly in continental rift settings. In my free time, I enjoy hiking, camping, backpacking, reading, yoga, and playing with my cat, Carl.

Shaunak Joshi
Ph.D. Student in Energy Resources Engineering, admitted Autumn 2022
BioI am Shaunak, from India. I am starting my PhD in Energy Science and Engineering with Prof. Daniel Tartakovsky and Prof. Hamdi Tchelepi. My research will primarily focus on pore-scale modeling of lithium-based batteries.
Prior to this, I graduated from the Indian Institute of Technology (IIT) Bombay with a Bachelor's and a Master's in Energy Science and Engineering. I love to play all sorts of sports, especially football, badminton, and cricket. You would usually see me running around the campus on odd days. Hit me up if you want to have a chat! -
Ayako Kawano
Ph.D. Student in Environment and Resources, admitted Autumn 2022
BioAyako Kawano is a Ph.D. student at Stanford University. Her research interests include the impact analysis of air pollution on population health and climate change in low- and middle-income countries using remote sensing data and machine learning methods. Before coming to Stanford, she worked as a Data Scientist at UN Global Pulse and as a Program Manager at the United Nations Industrial Development Organization (UNIDO).
