Forests in danger: not only fires!
We often talk about forests for their importance in climate as a carbon sink and oxygen source. For their great role in the preservation of biodiversity, both for vegetation and as habitat for many animal species, for their potential in recreational activities. However, we do not talk a lot about forests in relation to natural hazards. …[Read More]

Desert loess: formation, distribution, geoscientific value
Loess is an aeolian (wind-driven) silty sediment covering over 10% of the Earth’s land surface; it occurs predominantly in the mid-latitudes. On a global scale, loess is among the most widespread unconsolidated sediments, and of crucial importance for agricultural regions where loess deposits are known to form fertile soils because of its ability to store …[Read More]

Friedrich Mohs and the mineral scale of hardness
One of the most famous identification methods in the study of mineralogy is the Mohs Scale of Hardness. A comparative scale, based on the hardness of each mineral, it is a way geoscientists can compare minerals to each other and organise them based upon an easily testable physical characteristic. Each level of hardness has a …[Read More]

Climate Change & Cryosphere – A brief history of A68, the world’s largest iceberg
In July 2017, the world’s largest iceberg known as A68 calved from the Larsen C Ice Shelf, located in the western Weddell Sea, Antarctica. Since then, A68 has lost two chunks of ice, A68-B and A68-C, but still remains a giant after more than 3 years. How did it feel to be the greatest, A68? …[Read More]

The Sassy Scientist – Only Time Will Tell
Being a geophysicist, Eocenia is well aware of the fundamental cyclical rhythm of life – inbox time, coffee time, lunch time, nap time, scream-at-the-cluster time, tea time, pub time, late-night-coding time. But apparently stratigraphers just don’t accept this universal cycle, leaving us all with the question: When will geologists figure out time? Dear Eocenia, Ma …[Read More]

Do you know about the 3MT competition? What a challenging experience for a PhD student!
Effective communication plays a vital role in our PhD life. We spend significant amount of time working on a desk or in a lab performing our research for many years. However, if we do not effectively communicate our results and ideas to other scientists and researchers, our research will be unacknowledged. Of course, we all …[Read More]
