In the near-term, I am concentrating on oxic-suboxic-anoxic transitions in aquatic systems to better understand the relationship between redox disequilibria and microbes living in proximity to, or even mediating, steep redox gradients and pronounced geochemical interfaces. Microbes can use a wide range of electron acceptors in addition to oxygen for respiration. Microbial processes are thereby integral to all the major elemental cycles relevant to life on Earth, making oxic-suboxic-anoxic transitions and their associated changes in energy flow and chemical speciation of particular interest. Furthermore, processes occurring at oxic-suboxic-anoxic transitions of diverse temporal and spatial scales have been globally significant throughout Earth’s evolutionary history and are likely to be important in any aquatic environment that may potentially exist (or have existed) in extraterrestrial environments.
Preliminary results from samples collected by Doran’s team in 2005 indicated a unique stratified system at Lake Vida, with high ammonia, high iron, and high microbial counts. My participation in this expedition aims to collect clean, unobtrusive, in situ voltammetric profiling of the stratified brine prior to discrete sampling. Real-time in situ voltammetric measurements should assist targeted and efficient fluid collection, as well as quantify gradients of manganese, iron, and if present, various sulfur species of intermediate oxidation state.
