Explaining the Mysterious Plethora of Short Magnetic Field Reversals Observed by Parker Solar Probe and their Relation to the Origin of Solar Wind. In Switchbacks Explained: Super-Parker Fields – the Other Side of the Sub-Parker Spiral, N. A. Schwadron and D. J. McComas provide a simple geometric explanation for the source of “switchbacks” and associated large and one-sided transverse flows in the ...[Read More]

vEGU21: What makes a good CV?
This year for vEGU21 we couldn’t have our normal CV board for our attendee’s to share their skills and talents, so instead we added the ‘Ask me for my CV’ sticker that you can put in your profile to let people know that your CV is available. But what about the actual CV itself? Seismology Division Early Career Scientist Michaela Wenner has collected some of the best advice ...[Read More]

SENSOR: The AWARENESS project
“SENSOR” – stands for Seismological Experiments, Network Systems, Observations and Recovery In this blog series, we share news about recent or upcoming seismic experiments around the globe! The first blog of the SENSOR series follows a young researcher, Dr. Andreia Pereira, from the Instituto Dom Luiz of the University of Lisbon, who is working on the AWARENESS project and has explained to me the ...[Read More]

Climate Change and Cryosphere – What can we learn from the smallest, most vulnerable glaciers in the Ötztal Alps?
The Alps were the first mountains to be studied from a glaciological point of view in the 19th century and they host some of the most studied glaciers of Earth. Some of them are found in the Central Alps and in particular, the Ötztal Alps. Just to cite the most known and largest glaciers in this Alpine sector, we can mention Hintereisferner or Vernagtferner. But in the Ötztal Alps you can also fin ...[Read More]

New metric to interpret linear trends from short time series: Trend to variability ratio (TVR)
Availability of good quality data is essential to deduce meaningful information in all disciplines of science and technology. This statement is especially relevant in climate research, which is under constant scrutiny from sceptics. In order to better understand the Earth system response to the ongoing anthropogenic global warming, we require global observations of climate indicators at ver ...[Read More]

Tips on engaging outside of your echo chamber
In my previous blog, I highlighted that public engagement needs to go beyond traditional approaches such as lectures, since these tend to only attract audiences who are already highly interested in science. However, our science is relevant to (and funded by) everyone, so we have a duty to engage beyond simply this “scientific echo chamber”. But how do you even approach attempting this? It seems li ...[Read More]

What’s my age again? Comparing dating methods in loess
As you have learned from our previous posts, loess is a widespread terrestrial sediment, known to be an important archive for the changes of past environmental and climatic conditions. In order to use loess as a proxy, we first need to investigate the age of the sediments. In loess, different dating methods can be used, such as luminescence dating, radiocarbon dating, magnetic stratigraphy, and or ...[Read More]

Imaggeo On Monday: Transit of Venus over the Sun
The object of this photo is the transit of planet Venus in front of the Sun which took place on June 6th 2012 and was the last event of this kind until 2117! This is a very rare event with respect to a human life span and the transit always happens in pairs, 8 years apart, with a repeatability of more than two centuries. The picture was captured on the shore of the Black Sea, in Vama Veche, Romani ...[Read More]
