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]

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]

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]

Imaggeo On Monday: Erosion and suspension

This image shows bottomset beds from the Kerinitis Gilbert-type delta. The Pleistocene delta uplifts along the active southern margin of the Corinth rift in Greece. A bottomset bed is one where layers of sedimentary material lying along the bottom of a body of water near the point of entry of a stream are subsequently covered by foreset and topset beds in the formation of a delta. Thus in this ima ...[Read More]
