As has been previously discussed in Robert’s blog, fertile soil is an incredibly important resource that is fast running out in many regions of the world. It is true that soil’s importance for agriculture (and sustainable development) cannot be understated, but I wish to focus on another aspect of soil in this week’s blog– its ability to store carbon. One soil type in particular, peat, is an incre ...[Read More]
Our closest star, the Sun, is constantly emitting hot gas in all directions as its upper atmosphere, the corona, expands. This is known as the Solar Wind, also carrying with it an embedded magnetic field, the Interplanetary Magnetic Field (IMF). The IMF originates at the Sun and forms an enormous spiral throughout the solar system as the solar wind escapes radially, while the magnetic field-line ...[Read More]
The Arctic is changing rapidly and nothing indicates a slowdown of these changes in the current context. The Snow, Water, Ice and Permafrost in the Arctic (SWIPA) report published by the Arctic Monitoring and Assessment Program (AMAP) describes the present situation and the future evolution of the Arctic, the local and global implications, and mitigation and adaptation measures. The report is base ...[Read More]
The thick packs of ice that pepper high peak of the world’s mountains and stretch far across the poles make an unusual time capsule. As it forms, air bubbles are trapped in the ice, allowing scientists to peer into the composition of the Earth’s atmosphere long ago. Today’s Geosciences Column is brought to you by PhD researcher Ruth Amey, who writes about recently published resea ...[Read More]
Communicating the fragility of one of Earth’s remotest environments is hugely difficult, precisely due to the location of the poles. Jon Fuhrmann, a freelance science writer and guide on Antarctic cruises, discusses the potential benefits of taking tourists to these once inaccessible locations, especially when it comes to making members of the public aware of the challenges faced by the Eart ...[Read More]
Apart from Earth, there are a lot of Peculiar Planets out there! Every 8 weeks, give or take, we look at a planetary body or system worthy of our geodynamic attention. When the discovery of additional Earth-sized planets within the TRAPPIST-1 system was revealed last year, bringing the total to 7 planets, it captured the minds of audiences far and wide. This week, two of the authors from a 2017 Na ...[Read More]
Today we are happy to post our first interview and to thank our first interviewee, Paola Crippa for her contribution. The topic focuses on mortality from high concentration of particulate matter generated from widespread wildfires. This topic wants to be just the starting point to address another and broader theme: dealing with lack-of-data for research purposes in developing countries. This will ...[Read More]
Imaggeo, our open access image repository, is packed with beautiful images showcasing the best of the Earth, space and planetary sciences. Throughout the year we use the photographs submitted to the repository to illustrate our social media and blog posts. For the past few years we’ve celebrated the end of the year by rounding-up some of the best Imaggeo images. But it’s no easy task to pick which ...[Read More]
Take a look and try to identify anything around you that has phosphorus as a component. Phosphorus – the P element – is critical for life, like oxygen, nitrogen and carbon, being present in every plant, animal and bacteria. It constitutes cell walls, DNA, RNA and ATP, which transports energy to the brain. Our bones and teeth include phosphorus. Now look again and you might see that pho ...[Read More]
