  1. Researchers Find Evidence of Ancient Microbial Life in 3.51 Billion-Year-Old Rocks

    Teasing out biochemical information from ancient organic-rich sediments, notably the timing of the emergence of photosynthesis relative to…

  3. I'm still trying to process this one (because math, hard), but it does present an interesting framework to explain the preservation of #OrganicMatter in #sediment and when carbon really leaves Earth's superficial #CarbonCycle.

    Yet another study made possible by #IODP, that we could not do again without.

  4. Just published in Organic Geochemistry, "Fire-induced shifts in stalagmite organic matter mapped using Synchrotron infrared microspectroscopy", led by #ANSTO colleague Dr. Liza McDonough. We demonstrate for the first time that Synchrotron IRM is a promising non-destructive, high resolution (5 µm) technique for analysing stalagmite organic matter. The paper can be found #OpenAccess here: doi.org/10.1016/j.orggeochem.2

  5. Happy 1000th Google Scholar citation anniversary

    To a paper published in 2001 that saw me sampling rivers and sewage treatment plant final treated effluent in northeast England. And then analysing the water samples for their intrinsic fluorescence properties. How did that all come about?
    I had recently started a new position at the University of Newcastle, and had started to work with hydrologists to there. And I was using the latest fluorescence spectrometer technology to analyze organic matter characteristics in cave drip waters, groundwater and estuaries....
