We’ve been introducing you to a couple of new faces on the GfGD blog, bringing fresh ideas and perspectives on topics relating to geoscience and sustainable development. We’re delighted to have their input, and look forward to their posts. Today we interview Heather Britton – a recent graduate of the University of Cambridge (UK). Tell us a bit about yourself. I’ve recently graduated with a Master ...[Read More]
This stunning vista encompasses the south-western wilderness of Tasmania as seen from the Tahune air walk 60 m above the Huon river valley. In front lies the beginning of a huge UNESCO World Heritage Site, covering almost a fourth of the area of Tasmania. The site mostly consists of a pristine, temperate rainforest of Gondwanan origin that is home to the tallest flowering trees in the world; Eucal ...[Read More]
Over the next few weeks we’d like to introduce you to some new faces on the GfGD blog, bringing fresh ideas and perspectives on topics relating to geoscience and sustainable development. We’re delighted to have their input, and look forward to their posts. Today we interview Robert Emberson – based in Victoria, Canada. Hi there! Who are you? I’m Robert Emberson, and I’m delighte ...[Read More]
Although traditionally used to study earthquakes, like today’s M 8.1 in Mexico, seismometers have now become so sophisticated they are able to detect the slightest ground movements; whether they come from deep within the bowels of the planet or are triggered by events at the surface. But how, exactly, do earthquake scientists decipher the signals picked up by seismometers across the world? And mo ...[Read More]
“Summer break is over, which means we will continue with our Minds over Methods blogs! For this edition we invited Andrew Cross to write about his experiments with a new rock deformation device – the Large Volume Torsion (LVT) apparatus. Andrew is currently working as a Postdoctoral Research Associate in the Department of Earth and Planetary Sciences, Washington University in St. Louis, USA. ...[Read More]
Most of the energy that drives glacier melting comes directly from sunlight, with the amount of melting critically dependent on the amount of solar energy absorbed compared to that reflected back into the atmosphere. The amount of solar energy that is reflected by a surface without being absorbed is called the albedo. A low albedo surface absorbs more of the energy that hits it compared to a high ...[Read More]
Climate change is calling for various and multiple approaches in the adaptation of cities and mitigation of the coming changes. Because buildings (residential and commercial) are responsible of about 40% of energy consumption, it is necessary to build more energy efficient ones, to decrease their contribution to greenhouse gas emissions. But what is the relation with the atmosphere. It is two fold ...[Read More]
With more PhD and postdoc positions than there are tenured posts, landing a permanent job in academia is increasingly challenging. For some, years of funding and position uncertainty, coupled with having to relocate regularly is an unwelcome prospect. A changing job market also means that aspiring to the traditional, linear career path might be an unrealistic expectation. Skills acquired by those ...[Read More]
Apart from Earth, there are a lot of Peculiar Planets out there! Every 8 weeks, we look at a planetary body worthy of our geodynamic attention. This week Richard Ghail, lecturer in Engineering Geology at Imperial College London in the United Kingdom, discusses Earth’s sister: Venus. Geologists have long held the view that they only have the results of one experiment: Earth. The growing list ...[Read More]
Name of the proxy: Stable isotope ratios of carbonates in speleothems Type of proxy: Precipitation, atmospheric circulation, CO2 availability in soil, soil productivity Paleoenvironment: Continental environments Period of time investigated: Present day to 10 million years How does it work? Speleothems are inorganic carbonate deposits growing in caves that form from super-saturated cave waters (wit ...[Read More]
