Increased use and improved methodology of carbonate clumped isotope thermometry has
greatly enhanced our ability to interrogate a suite of Earth‐system processes. However, …

The potential for carbonate clumped isotope thermometry to independently constrain both the
formation temperature of carbonate minerals and fluid oxygen isotope composition allows …

Lake Fryxell is a perennially ice-covered lake in the McMurdo Dry Valleys, Antarctica, with a
sharp oxycline in a water column that is density stabilized by a gradient in salt concentration. …

Clues to the evolutionary steps producing innovations in oxygenic photosynthesis may be
preserved in the genomes of organisms phylogenetically placed between non-photosynthetic …

The evolution of oxygenic photosynthesis was the most important geochemical event in
Earth history, causing the Great Oxidation Event (GOE) ∼2.4 by ago. However, evidence is …

Precambrian marine carbonate strata are commonly assumed to have formed in warm‐water
carbonate factories due to the temperature dependence of non‐skeletal carbonate …

Perennially ice-covered, meromictic lakes in the McMurdo Dry Valleys, Antarctica, are useful
models to study the relationship between cyanobacterial and environmental variables. They …

Carbonate clumped-isotope thermometry is a promising technique that has the potential to
help decode the significance of the variability of both physical and geochemical compositions …

Lake Vanda is a perennially ice-covered, closed-basin lake in the McMurdo Dry Valleys,
Antarctica. Laminated photosynthetic microbial mats cover the floor of the lake from below the …

Ecological communities are regulated by the flow of energy through environments. Energy
flow is typically limited by access to photosynthetically active radiation (PAR) and oxygen …
