Most of us know about the existence of waves and tides. We can see them along our coasts and, even if we do not pay much attention, we also know that waves and tides move sediment that rests on the seafloor: sand, mud, shells and…plastics. We all can see ripples and small channels on beaches …[Read More]
As you have learned from our previous posts, loess is a widespread terrestrial sediment, known to be an important archive for the changes of past environmental and climatic conditions. In order to use loess as a proxy, we first need to investigate the age of the sediments. In loess, different dating methods can be used, …[Read More]
The Geosciences are at the forefront of the fight against climate change. It is Geoscientists who discovered it and explained it, and it is Geoscientists who work to understand it and its consequences. Geoscientists undoubtedly will be amongst those who will lead us to the solutions. However, it often seems that Geoscientists are solely associated …[Read More]
In these days fossils are becoming the new Hollywood stars as we are more and more pushed to use new -or sort of new- approaches for disseminating paleontology which pass through a screen. Technology is providing us with several ways to reach homes, colleagues throughout the world, or classrooms to share our research. The EGU …[Read More]
When I graduated in the 80’s, a job in oil and gas was seen as a glamorous and exciting career for a geoscientist. Even some dramatic falls in the oil price could not dent the optimism within the industry, and oil cities like Calgary thrived. However, life for geologists working in our city has changed …[Read More]
There is a place in the NE of Mexico where anyone can learn heaps about the dynamics of the ground beneath our feet while enjoying the wonders of the desert. Geologists call the area ‘La Popa Basin’. La Popa means “The Bow”, a name that comes from the shape of one of the mountains in …[Read More]
While many of us are experienced in giving presentations before a variety of audiences, for some, the switch to a remote presentation format can be daunting. With this in mind, and based on our experiences at sedsonline.com I have put together the following tips for our community – these are in no way exhaustive, but …[Read More]
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]
By Mike Simmons and Andy Davies. It seems that geoscience is facing something of an existential crisis. The September 2020 issue of Geoscientist, the magazine of the Geological Society of London, contains a number of articles on the future of geoscience and its relevance to society. At the heart of the concerns are a drop …[Read More]
Every year, the Stratigraphy, Sedimentology and Paleontology Division awards one scientist for their outstanding contribution to stratigraphy, sedimentology or paleontology with the Lamarck medal in recognition of the scientific achievements of Jean-Baptiste Lamarck (Bazentin-le-Petit, 1-02-1744 – Paris, 18-12-1829). It was the 11 May 1800 when Jean Baptiste Lamarck presented a lecture at the Muséum national d’histoire naturelle …[Read More]
