GeoTalk: Meet Marisa Storm, Molecular Fossil researcher!

Marisa Storm

  Hi Marisa. Thank you for joining us today! Could you tell our readers a bit about yourself and your research? Hi, I am a geologist and organic geochemist, currently working as a postdoc at the NIOZ Netherlands Institute for Sea Research based on the island Texel. After my geology-focused undergraduate and master studies in Germany at the RWTH Aachen and Heidelberg University, I graduated wi ...[Read More]

Imaggeo On Monday: Erosion and suspension

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]

Imaggeo on Mondays: how short-term storms can impact our landscapes

Imaggeo on Mondays: how short-term storms can impact our landscapes

In the Sierra de Aconquija, a mountain range in the southern Central Andes of Argentina, strong storms often come and go at a moment’s notice, but they can have a long-lasting impact on the Earth’s surface. The thunderstorm cell featured in this photo formed in less than half an hour, giving all those nearby only a few minutes to take cover. Mitch D’Arcy, a geomorphologist and postdoctoral researc ...[Read More]

Imaggeo on Mondays: Small scale processes, large scale landforms

Imaggeo on Mondays: Small scale processes, large scale landforms

This picture was taken in a sea cliff gully landscape at the Portuguese coast. It shows the microrelief which small scale wash and erosional processes produce in these poorly consolidated sediments. These small scale landforms could be interpreted as initial stages of larger scale gully landforms, which can be seen in the back. This highlights the importance of regarding scales and scale linkages ...[Read More]
