Welcome to my personal website!

I am Ronnakrit Rattanasriampaipong, but you may know me by many other names! “Ronnie” is what I normally go by in English-speaking conversations. I am currently a NOAA Climate & Global Change Postdoctoral Fellow (Class 33) at the Department of Geosciences at the University of Arizona in Tucson, AZ, working on the project “TEXAS: Towards a full proxy system modeling of TetraEther indeX of Ammonia oxidizerS and reanalysis of temperature trends for the past 100 million years” with Dr. Jessica Tierney as my mentor.

In Fall 2023, I earned my doctoral degree in Oceanography from the Department of Oceanographyat Texas A&M University in College Station, TX. I have spent five years and one semeseter working in the with Paleoceanography and Organic Geochemistry Lab under the supervision of Dr. Yige Zhang. My dissertation research focuses on leveraging the use of lipid biomarkers, specifically Glycerol Dialkyl Glycerol Tetraethers (GDGTs) — membrane-spanning lipids of ancient marine microbes, beyond their typical SST reconstruction application (commonly known as TEX₈₆ paleotemperature proxy). One of my dissertation chapters has published in Proceedings of the National Academy of Sciences (PNAS) in 2022, demonstrating that GDGT compositions recorded in marine sedimentary archives likely reflect ecological shifts of source organisms over geological history. The findings holds a crucial implication TEX₈₆ proxy, one of a few geochemical proxies that can provide reliable ocean temperature reconstructions over the past 100 million years.

Paleotemperature proxy data form the cornerstone of paleoclimate research and are integral to understanding the evolution of the Earth system across the Phanerozoic Eon. Here, we present PhanSST, a database containing over 150,000 data points from five proxy systems that can be used to estimate past sea surface temperature. The geochemical data have a near-global spatial distribution and temporally span most of the Phanerozoic. Each proxy value is associated with consistent and queryable metadata fields, including information about the location, age, and taxonomy of the organism from which the data derive. To promote transparency and reproducibility, we include all available published data, regardless of interpreted preservation state or vital effects. However, we also provide expert-assigned diagenetic assessments, ecological and environmental flags, and other proxy-specific fields, which facilitate informed and responsible reuse of the database. The data are quality control checked and the foraminiferal taxonomy has been updated. PhanSST will serve as a valuable resource to the paleoclimate community and has myriad applications, including evolutionary, geochemical, diagenetic, and proxy calibration studies.
