Zachary (Zack) Kaufman, UCSC Climate Dynamics

I am currently a PhD candidate in the Earth and Planetary Sciences Department at UC Santa Cruz.  In 2016, I received my undergraduate degree from Wesleyan University in Earth and Environmental Sciences.    

I am broadly interested in the climate system of Earth's polar regions, which feature fascinating, complex interactions between the ocean, atmosphere, and sea ice. I primarily work with Professor Nicole Feldl, applying novel causal discovery techniques to quantify the physical mechanisms underlying polar climate change. Currently, my research utilizes large geophysical datasets from state-of-the-art climate models. In the past, I have worked on polar paleoclimate reconstructions using deep-sea sediment cores in the Weddell Sea.

High-resolution modeling capabilities have enabled new research on open-ocean polynyas, an important  sea-ice feature in the Southern Ocean. See our recently published research on the topic, conducted in collaboration with the US Department of Energy's HiLAT Project:

I am currently developing causal effect networks to link the vertical structure of Arctic Warming to local and remote Processes.  Graphics are produced in Tigramite: A Causal Time Series Analysis Python Package
