Sandwiched between the U.S states of Mayland, Delaware, Pennsylvania, New York State, the District of Columbia and Virginia, lies Chesapeake Bay, the largest estuary in North America. It is of huge ecological importance: “the bay, its rivers, wetlands and forests provide homes, food and protection for countless animals and plants”, says the Chesapeake Bay Program. Up to 150 major rivers and stream ...[Read More]
Each month, Jesse Zondervan picks his favourite posts from geoscience and development blogs/news, relevant to the work and interests of Geology for Global Development . Here’s a round-up of Jesse’s selections for the past two weeks: If you thought we were safe from Tsunamis in Europe, think again. I was surprised to find out Geneva experienced a Tsunami in 563 triggered by a mudslide. On a simila ...[Read More]
Geotalk is a regular feature highlighting early career researchers and their work. Following the EGU General Assembly, we spoke to Yadong Sun, the winner of a 2017 Arne Richter Award for Outstanding Early Career Scientists, about his work on understanding mass-extinctions. Using a unique combination of sedimentological, palaeontological and geochemical techniques Yadong was able to identify some o ...[Read More]
To study how the ocean behaves in the glacial fjords of Antarctica and Greenland, we normally have to go there on big icebreaker campaigns. Or we rely on modelling results, especially so to determine what happens when the wind or ocean properties change. But there is also a third option that we tend to forget about: we can recreate the ocean in a lab. This is exactly what our Bergen-Gothenburg tea ...[Read More]
The Geodynamics 101 series serves to showcase the diversity of research topics and methods in the geodynamics community in an understandable manner. We welcome all researchers – PhD students to Professors – to introduce their area of expertise in a lighthearted, entertaining manner and touch upon some of the outstanding questions and problems related to their fields. This month we continue the con ...[Read More]
In this post, originally published in June 2017 on the blog of the Geological Society of America (GSA), Terri Cook, a science and travel writer and former winner of the EGU’s Science Journalism Fellowship, argues the importance of quality science communication as a means for scientists to make their research accessible to a broad audience. One way to achieve this is working with a science jo ...[Read More]

A blazing sky and shimmers cast by water ripples frame the spectacular beauty of one of the world’s oldest treasures: an evergreen rainforest in Thailand. Today’s featured image was captured by Frederik Tack, of the Institute for Space Aeronomy in Brussels. This picture was taken during sunset between the limestone mountains with the sunlight reflecting on beautiful Ratchaprapha lake i ...[Read More]
Post by Andy Baker, Professor researching groundwater, caves, past climate, organic carbon and more at the University of New South Wales, in Australia. __________________________________________________ We know a lot about the carbon cycle, right? Increased carbon dioxide emissions since the Industrial Revolution have perturbed the carbon cycle. This has led to rising atmospheric carbon dioxide le ...[Read More]
Earthquakes: nucleation, triggering, rupture, and relationships to aseismic processes – 2-6 October 2017, Cargèse (Corsica) A summer school in October, isn’t that a bit late? Well, not if it is held in Cargèse, a small town at the coast of Corsica! After a successful first edition in 2014, scientists from all over the world gathered again last week at the beautifully located ‘Institut d̵ ...[Read More]
