JISAO Announces New Post-Doctoral Researchers

Four new Research Associates will be joining the Joint Institute for the Study of the Atmosphere and Ocean (JISAO) in 2016 and 2017. The JISAO post-doctoral program gives each researcher the opportunity to construct their own project, encouraging them to think broadly and work closely with scientists at the University of Washington and local NOAA laboratories. Following are brief overviews of each researcher, their projects, and the scientists with whom they’ll be working:

Anne Gothmann
Anne received a PhD in Geosciences from Princeton University. Her focus will be on how calcifying organisms respond to environmental change, especially temperature and ocean acidification. Anne is an expert in the stable isotope geochemistry of divalent cations and has used these isotope systems to provide new insight into climate variability. She will also conduct novel experiments that will identify which variables have the largest effect on calcification. Together, these complementary approaches will help determine if recent calcification in northeast Pacific deep sea corals are anomalous and will help better predict how it will respond to future change. Anne will be working with Casey Saenger, a research scientist with JISAO, and Alexander Gagnon, an assistant professor with the UW School of Oceanography. 

Hannah Horowitz
Hannah attends Harvard University where she will soon receive a PhD in Earth and Planetary Sciences. She will be working with Becky Alexander in the UW Department of Atmospheric Sciences where she will lead the first study to examine climate change impacts on the sea ice source of sea-salt aerosol, and estimate the climate impacts of potential changes to sea-salt aerosol resulting from changing sea ice and warming ocean temperatures in a future climate scenario. The process-level understanding gained from her results will improve future studies of chemistry-climate interactions and climate change impacts and inform parameterizations in simpler, computationally inexpensive models.

Cristian Proistosescu
Cristian is a student at Harvard University and is completing a PhD in Earth and Planetary Sciences. He will be investigating the interaction between ocean heat uptake and regional climate feedbacks across a range of temporal and spatial scales, with the aim of exploring the prospects for (and limitations of) what can be learned about Earth’s climate sensitivity from the instrumental and paleo records of climate variability and change. His research will build a process-level understanding of how modes of climate variability have consequences for Earths’ global energy budget. These are timely and important topics, given the recent evidence that climate sensitivity is variable, and that future warming may be underestimated from modern climate observations. Cristian will be working with Gerard Roe in the UW Department of Earth and Space Sciences and Kyle Armour with the UW Oceanography Department and Department of Atmospheric Sciences. 

Hannah Zanowski
Hannah will soon receive a PhD in Atmospheric and Oceanic Sciences from Princeton University. Her project will include both observational analysis of decade-to-decade historical water-mass changes in the Southern Ocean as well as diagnosis of model output, specifically to study full-depth southern ocean responses to changes in wind and freshwater forcing when they are applied in the open ocean vs. along the coast. Various climate models form Antarctic Bottom Water differently (some in open ocean polynyas and some on the continental shelves and slopes). By comparing observations and different climate models, Hannah hopes to elucidate key mechanisms for variability in the Southern Ocean limbs of the meridional overturning circulation. She will be working with Cecilia Bitz and Kyle Armour in the UW Department of Atmospheric Sciences and Greg Johnson at the NOAA Pacific Marine Environmental Laboratory.
