This is a transmitted light microscope image of a thin section – a 50-micron thick sliver of rock. This sample was collected from Jebel Hafit, a mountain which straddles the United Arab Emirates and Oman border. Jebel Hafit is approximately 900 m high and is made up of Eocene to Miocene age carbonate rocks which were mainly deposited in a shallow water, tropical setting. More specifically, this im ...[Read More]

During my PhD I was working at the German Neumayer III station in Antarctica for my research on polar atmospheric chemistry. Since my instrument was set up on an observatory south of the main station, every day I would walk past a Scott pyramid tent to go and do my research. One day, in the midst of an Antarctic storm, I caught sight of the tent deep in the drifting snow, and took this picture. Th ...[Read More]
