Every two years a group of PhD students disappear into the geological wilderness for the RSES Student Field Trip. In 2014, students spent two weeks camping in the Australian outback investigating the regional geology of Central Australia. After many discussions and presentations about exotic and tropical locations, the student cohort settled on a geological road trip around Tasmania. Here is a quick overview of the geological history of Tasmania and some of the cool sites we managed to visit.
This weeks post is from third year Msci geology exchange student Jesse Zondervan who has been visiting RSES for the last year. This was originally posted on the 10th April on Jesse’s personal blog site.

The two week mid-semester break started off with a field trip to Wee Jasper, in the bush of New South Wales. After five days of walking around in a field shirt and hat without phone signal I arrived back in civilization on Wednesday evening. Back in Canberra I spent the rest of my time writing for my assignments and the student newspaper. I also worked on the microscope with Janelle and played some boardgames with the B&G boardgames society.
Earlier this year I was lucky enough to get to go over to California for a few days all in the name of science. We stayed up in the hills behind Berkeley, a short walk away from the instrument we were using. The view from our hotel room was pretty amazing with views across San Francisco, the Golden Gate Bridge and the Pacific Ocean.

Last week I snuck into the ARC Centre of Excellence for Climate System Science’s scientific paper writing workshop, held here at the ANU. I thought I would share a few of the nuggets of wisdom I learnt during my 3 days at the workshop. I am not a climate scientist but was lucky enough to score a place in this workshop.
In the widely used pyrolite model for mantle composition developed by Ted Ringwood (a former Professor at RSES), the chemistry of the Earth’s mantle is dominated by a small handful of oxides: SiO2, MgO, FeO, CaO, and Al2O3, with smaller amounts of Na2O, TiO2, and Cr2O3. The study of the physical and chemical properties of the Earth’s mantle is predominantly the study of the mineral phases formed by these oxides. However, chemical elements occurring at minor and even trace abundance can be almost as important for the properties of the mantle.

Following the tradition of Disney films produced by Pixar Animation Studios, the recent 2015 release of Inside Out was accompanied by a short video simply called Lava. Here it is:
Eleanor’s post last week on scale provided the perfect segue for my first ever blog (!). Like many people when I think about my work, I find it useful to visualise processes to better understand them. I do this when I think about the interactions of atoms, tectonic plates and planets for example. In geoscience it seems we often work on scales that are either too small to see or too large see all at once (or at all) and thus an imagination is vital. It is a misconception that creative people study arts whilst regimented people study science.
