Desert loess: formation, distribution, geoscientific value

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 water and retain nutrients. Loess is compr ...[Read More]

TS Must-Read – Mckenzie and Parker (1967) The North Pacific: an example of tectonics on a sphere

The paper describes how large, rigid, aseismic regions can be defined with Euler’s theorem, which describes the geometry of motion on a sphere, i.e. the Earth’s surface. Points on these large and rigid blocks move in relation to other blocks describing small circles set by their rotation pole. The paper describes this as “paving stone theory”, where tectonic plates are “paving stones”, and success ...[Read More]

Forests in danger: not only fires!

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. Indeed, forests can be severely affected by natural hazards. T ...[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? Being the greatest With a length of 175 km and being about 50 km wide, this giant iceberg also appropriately ...[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 or Myr? Either would ...[Read More]

Ana Margarida Neiva – A woman as hard as granite

  Ana Neiva was born on May 7 1941 in Cedofeita, Porto, northwest Portugal – a city carved in granite. Her childhood and youth were spent in Coimbra, where her father worked. João Cotelo Neiva was an eminent geologist and professor at the University of Coimbra, one of Europe’s oldest universities. His influence was decisive for her interest in geology and her scientific career.     ...[Read More]
