Ethics and Geosciences: discovering the International Association for Promoting Geoethics

Geoscientists do not have to deal only with technical matters, but have to think also about the ethical implications related to their discipline. To increase the awareness of researchers on the ethical aspects of their activities, it has been created the International Association for Promoting Geoethics (IAPG). To better understand what geoethics and the IAPG are, we interviewed Silvia Peppoloni, ...[Read More]

Decreasing Moon Imaggeo

This picture shows the decreasing Moon on May 6, 2015, two days after the full Moon, as viewed from Hamburg, Germany. There are still 96.4% of the lunar front illuminated. The Moon does not glow on its own, but its surface reflects the sunlight. The Sun always illuminates a complete half of our natural satellite, which, in its orbit around our planet, always turns its face (which we see at full Mo ...[Read More]

SeismoChat: How to disarm earthquakes

Solmaz Mohajder is a researcher at the Earth System Dynamics Research group of University of Tübingen in Germany. She has published an online database and an interactive map for active faults in Central Asia (Mohajder et al., 2016).  More recently, Solmaz and her colleagues have compiled fault slip rates to investigate whether deformation rates from GPS and from geologic observations provide consi ...[Read More]

Image of the Week – Ice caps on Mars?!

Much like our Planet Earth, Mars has polar ice caps too, one for each pole: the Martian North Polar Ice Cap (shown on our image of the week) and the Southern Polar Ice Cap. Yet, their composition and structure reveals these ice caps are quite different from those of Planet Earth… Mars refresher   As a refresher, here are some Mars facts: Mars is the 4th planet from the sun. Its equatorial dia ...[Read More]

The Case Against Fieldwork – How can we internalise the carbon cost of fieldwork, as scientists who investigate the earth system?

The Case Against Fieldwork – How can we internalise the carbon cost of fieldwork, as scientists who investigate the earth system?

There are few, if any, fields of human study for which fieldwork is more fundamental than geology. For many geologists, the solid earth itself is their subject, and this means observations can be made at any given location on the planet. Moreover, the local quirks of different environments almost necessitate a diverse range of study sites for us to fully comprehend the differing processes that gov ...[Read More]

Peat in the Tropics

Peat in the Tropics

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]

How do we study the magnetosphere?

How do we study the magnetosphere?

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]

Image of the Week – Arctic changes in a warming climate

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]
