When someone says ‘hydrogen’, what do you think of? I think BOOM! I wasn’t sure why I thought that until I looked up the range at which hydrogen can explode compared to methane. And indeed hydrogen is more flammable. Methane’s range of concentration in which it can explode is between 5 and 15% (so lower […]
There was a recent article in the Eos Science News by the AGU. As a whole the AGU is doing a great job at being relevant and topical in today’s geoscience world. Its dynamic and attracts a lot of young professionals, which is fantastic. The article that caught my eye was titled “Teaching Geoscience History […]
“Without data, you are just another asshole with an opinion”, said John Ferm standing at the blackboard, chalk in one hand and a cigar in the other with smoke swirling around his head (this was, after all, 1985). It’s a phrase John (my MSc and PhD advisor) would often use when we, his students, started […]
I was flying through the chill Christchurch air with my arms outstretched like some newbie superhero about to make a hard landing on frosty, frozen gravel. I had just been cycling through Hagley Park on my way to work thinking about how to put together a disparate set of papers for a book when I […]
Though mostly overlooked by sedimentologists and climatologists coal provides highly detailed information on past climates and tectonics. In a recent paper* by myself and my colleagues (available Here) we take a look at a very thick (>40 m) coal of Early Cretaceous age in Inner Mongolia, near the borders with Russia and Mongolia. Using stable […]
Two geologists walk into a bar. The first orders a ‘Flaming Volcano’ (he’s a neo-tectonics/Quaternary guy). Without blinking an eye the bartender asks him what sort of rum he’d like. The second geologist orders a ‘Black Coal’ Stout (she is an organic petrologist). Everyone in the bar freezes then slowly slinks out the door …. […]
There is a certain similarity between rocks and photography. I suppose it has to do with stopping time. When I look at an outcrop of sediment, whether it is from the Quaternary or the Cambrian, it is like a snapshot of time for me, frozen, and waiting for interpretation. When I take a photo, I […]
It was like jumping off the end of a pier into unknown depths with unknown dangers – but a quick calculation (in actuality lots of deep reflection) indicated that it was safe…-ish; nevertheless it was exhilarating. Thus, Cipher was born. In early September 2010 Cipher started trading and by late September we had our first […]
It would not be untrue, though perhaps unwise, to say to a burly coal miner ‘your coal is full of holes’. Indeed, a fundamental property which makes coal such a special and unique material – and has implications for coal properties ranging from not just methane holding capacity but also activated carbon and liquefaction – […]
Sometimes I am asked how I became a coal geologist. My son has asked me several times; sometimes because he has forgotten, sometimes because he just wants to hear a good story from his Dad. More than seldom I get asked by random people; some curious how a scientist starts out (and stays) being a […]
