Our lab (based at WHOI and led by Alan Seltzer at UCD) specializes in measurement and modeling of gas isotope tracers applied to explore research questions related primarily to hydrogeology, oceanography, and volcanology. To learn more about our research, view recent publications, or inquire about analytical services, please browse the site and feel free to get in touch. We have recently merged with the dissolved noble gas side of the WHOI IGF, a longstanding facility for oceanographic noble gas measurements that has undergone recent upgrades.
