LOESS IN TRANSLATION

LOESS IN TRANSLATION

Loess is a mineral, aeolian deposit with a range of definitions in literature, which class it as either a sediment, soil, or rock. Some classic texts suggest that “loess is not just the accumulation of dust” [1], and it must include additional processes such as loessification, calcification, pedogenesis, and in-situ weathering. The definition adopted depends on the scientific background and the qu ...[Read More]

How Open Science may help us during and after the pandemic

How Open Science may help us during and after the pandemic

As Hedding et al. (2020) indicate, it is “not business as usual” for higher education across the globe. There are many testimonies by scientists who are struggling to work while their children are stuck at home during the coronavirus pandemic (Langin, 2020). Indeed, it is very complex to stay at home to raise and home-school kids and remain productive as an academic while living through a pandemic ...[Read More]

Field work in winter in Iceland: The beautiful nature of Strokkur geyser

Field work in winter in Iceland: The beautiful nature of Strokkur geyser

I was fascinated and excited on my first trip to Iceland in August 2010; just a few months after the eruption of Eyjafjallajökull that affected the air traffic across Europe for a few days. Besides these dangerous volcanoes, the Icelandic landscape is beautiful, rough, wide and impressive with elements such as water and ice interacting directly at some locations. Part of this trip was, of course, ...[Read More]

Imaggeo On Monday: Great Sand Dunes Sunset

Imaggeo On Monday: Great Sand Dunes Sunset

On a late afternoon in Colorado’s Great Sand Dunes, the sun came out from behind the clouds for a brief moment before it went behind the horizon, illuminating the stoss side of an eroding dune. Sand originated from lacustrine deposits in the San Luis Valley; the Sangre de Cristo mountains, which can be seen in the background, provided a source of some of the sand. This image therefore illust ...[Read More]

#vEGU21: Gather Online – what you need to know.

#vEGU21: Gather Online – what you need to know.

On November 2nd, EGU opened the call for abstracts and communicated that 2021 will see the General Assembly going again fully virtual. It seems a very considerate choice, giving that the COVID-19 pandemic still pervades our lives and makes impossible safe planning of events that include travelling and in-person contacts so far ahead in time. Let’s see what we have to know to get ready for it based ...[Read More]

The never-ending 2020 hurricane season

The never-ending 2020 hurricane season

Iota, this is the name of the last category 5 hurricane in the Atlantic Ocean. Iota is a non-name because normally hurricanes are named by NOAA starting from A to Z but when the alphabet is over, they are just identified from a letter of the Greek alphabet. Iota is a special cyclone not just because its name implies that the hurricane season is particularly rich in storms but also because of its e ...[Read More]

Using Milankovitch Cycles to create high-resolution astrochronologies

Using Milankovitch Cycles to create high-resolution astrochronologies

This year marks the 100th anniversary of Milutin Milankovitch’s first paper about Earth’s climate. Milankovitch argued that the amount of solar radiation Earth receives, and hence its climate, varies cyclically as its orbit changes due to gravitational tugs from the other planets. His climate theory fell into disrepute during the 1950’s but was rehabilitated in the 1970’s.   Today, many peopl ...[Read More]

Did you know… that you can read the edge of Greenland’s ice as an open book?

Did you know… that you can read the edge of Greenland’s ice as an open book?

Scientists struggle to get ice samples from the depths of glaciers where fundamental pieces of information about the climate of Earth are stored. But in many places around the periphery of the Greenland Ice Sheet, you don’t need to drill a deep ice core to obtain ancient ice, you can simply walk across the ice sheet’s margin and look at the layered ice surface. There you can read the ice as though ...[Read More]

On the way back to Mercury

On the way back to Mercury

It is the smallest planet of the Solar System, the closest to the Sun and the quickest at orbiting around it, the one with the least inclined and most elongated orbit, the only one where a day lasts two-thirds of a full year, the one with the highest bulk density. Mercury is a planet of extremes, but rarely visited by space missions (compared to Mars, Venus and the Moon). This week Dr. Nicola Tosi ...[Read More]
