Lunch… and Glycerol Dialkyl Glycerol Tetraethers

Aug 24, 2015 No Comments by 198 views
The last plenary talk of the conference was given by Professor Ann Pearson of Harvard University and provided a detailed overview of recent advances in the understanding of the TEX86 proxy. I’m entirely new to this proxy, having only heard it mentioned very briefly in the past so I found the talk particularly informative. (If […]

Words from the ghost

Aug 22, 2015 No Comments by 295 views
My role at Goldschmidt 2015 was mostly photography. With a side portion of blogging thrown in, like a salad relish afterthought. There was also the poster of course, presenting my PhD hydrothermal experiment work. Poster sessions make me nervous. In fact, most social events make me nervous. I’m a nervous kind of creature. A flavour […]

Remember the hydrosphere!

Barbara Sherwood Lollar from the University of Toronto, Canada gave the plenary session this Wednesday on “Dark Energy from the Deep Hydrosphere: Water-Rock Reactions Sustaining Deep Subsurface Microbiology. This was actually quite a different set of water-rock reactions than what I focus on, thus ever-confirming the wide range of topics that geochemistry encompasses. I really […]

A damp Moon?

Aug 21, 2015 No Comments by 242 views
For almost 50 years the Moon was considered dry. Then in 2008 Alberto Saal and colleagues published a paper detailing the discovery of water in lunar fire fountain glasses. These findings (& a study by MCubbin et al 2007) initiated a community-wide reincarnation of lunar volatiles research.Later work would advocate in one extreme a lunar […]

Thoughts from a First-Time Attendee

Aug 20, 2015 No Comments 172 views

When I first arrived bright-eyed (well actually super sleepy) early Monday morning, I still had no idea exactly what this week would be like. That first day all seems like one strange chaotic dream as I was trying to grasp the “conference” routine and ended up just wandering quite aimlessly around for the better part […]

How comet impacts may have formed the building blocks of early life

Aug 19, 2015 No Comments 300 views

Proteins form the machinery of life: they catalyze the chemical reactions that allow organisms to gain energy and reproduce. A study presented at the 2015 Goldschmidt conference shows how oligopeptides, the precusors of proteins, might have been formed when comets impacted the Earth nearly 4 billion years ago. Comets are believed to contain substantial quantities […]
