Phosphate use for fertilisers, essential in modern agriculture, is hitting an all time high while resources are being heavily depleted. Flo discusses the background, numbers, geopolitics and potential solutions behind the issue of ‘the end of phosphorus’. The Issue The dilemma over diminishing natural resources is a topic of our times with the daily bulletins filled with reports relate ...[Read More]
James Hickey is a PhD student in the School of Earth Sciences at the University of Bristol. A geophysicist and volcanologist by trade, his PhD project is focussed on attempting to place constraints on volcanic unrest using integrated geodetic modelling. The newly discovered submarine Tamu Massif (pictured below), approximately 1500 km east of Japan, has been proposed as the wo ...[Read More]
One year has passed since I first wrote a post for this occasional blog. Now, 12 months, 22 posts and 7500 page views later, here’s a quick look back. For me, this has been a way of using some of my back catalogue of field photographs, of fleshing out a bit of context around papers I have been working on, and adding a little commentary on some more topical aspects. I am pleased with the results so ...[Read More]
You’re standing on a mountain peak, with a fabulous field site before you. Wanting to capture the moment, you take out your iPhone, snap a dozen pictures and your mobile stitches them together beautifully – a nice record to show your colleagues back in the office. Unfortunately, not all field sites are so easy to capture – especially when you need to do a little science with the images. Seafloor p ...[Read More]
Every geologist has heard the story of the birth of the Himalayas; India crashes into Asia and they crumple up, sending the seafloor into the sky, melting the crust and forming the highest mountains on earth. The mountains are still rising, and for that reason the region is prone to earthquakes, landslides and flash floods. The mountains also make the boundary between India and the rest of Asia a ...[Read More]
The past summer has seen a great deal of media coverage of fires burning across the globe. When I consider what to write about for the blog, it has often been difficult to avoid commenting on yet another instance of a fire burning somewhere. This has been especially difficult given my current research project investigates biomass burning aerosol from deforestation and agricultural fires in Brazil. ...[Read More]
The northern lights, or aurora borealis, are created as charged particles interact with the Earth’s atmosphere. These electrons are part of the solar wind and as they pass through the Earth’s magnetic shield (the magnetosphere); the charged particles collide with those in our atmosphere, emitting light. In the southern hemisphere this phenomenon is known as the aurora australis, but both are caus ...[Read More]
KT Cooper is a PhD student in the School of Earth Sciences at the University of Bristol. A carbonate geochemist by training, she is currently on a three-month secondment to Houston, Texas, USA working with Exxon Mobil. Recently, I was lucky enough to visit a fellow Bristol Earth Sciences PhD student in Vancouver, Washington for a weekend of volcano-spotting (and hiking) in the Cascades. As a non-v ...[Read More]
Our latest 10 Minute Interview is with Jennifer Clear, a fellow PhD student here in the School of Environmental Sciences, University of Liverpool. She is approaching her submission deadline and will soon be leaving to take up a PostDoc position in Prague, Czech Republic. We will be sad to see her go! Jen has kindly helped on a number of my fieldwork expeditions as well as teaching me how to spot ( ...[Read More]
Greenhouse gas levels and globally averaged surface temperatures are both on the rise. Whilst slow increases in temperatures are not easily perceived as threatening, and might even be welcomed by some, climate change can also include fast and sudden changes. These sudden changes could have disastrous effect on not only us humans, but also life on this planet more generally. When it comes to places ...[Read More]
