PI- Kranz (2017) prior to CCE-LTER on the R/V Revelle

I received my PhD at the Alfred-Wegener-Institute for Polar and Marine Research (AWI) with Dr. Bjoern Rost working of CO2effects on the N2-fixing cyanobacterium Trichodesmium. After a short Post-Doc in the same group I had the opportunity to work with Prof. François Morel at Princeton University on the carbon acquisition of Southern Ocean phytoplankton while continuing my work on CO2effects on Trichodesmium under Fe-limitation. In 2014 I started at the EOAS department at FSU as an Assistant Professor. I currently work on several projects including CO2effects on the dinoflagellate Karenia brevis, CO2and light effects on the diatom Pseudo-nitzschia,Thalassiosiraand light effects on the cyanobacteria Synechococcusand Prochlorochoccus. In my work at FSU, I am building upon my work as a PhD student and Post-doctoral researcher and continue to increase my portfolio to better understand the regulation of physiological processes of phytoplankton under environmental change. While working mainly in the laboratory, I also conduct fieldwork. In 2012 I spent 2 month at Palmer station in Antarctica and in 2017 I participated in the CCE-LTER process cruise in  which I measured net community productivity using a membrane inlet mass spectrometer.

Tristyn B. (PhD candidate) presenting her data on phytoplankton light acclimation to different light sources

Tristyn is a 4thyear graduate student. She is currently working on a project analyzing the response of the toxic dinoflagellate to changes in CO2. Here, processes such as productivity, carbon acquisition and toxin production are investigated. Tristyn is also working on a project analyzing the (us)suitability of different commercially available “growth” light sources. Here photophysiology, growth and productivity is investigated.
