A thought-provoking and wide-ranging talk yesterday by Andy Wickert, University of Minnesota.
His group has tracked changes in drainage patterns during the final deglaciation of Minnesota (~11 thousand years ago) to changes in erosion rates since the advent of mechanical agriculture.

Transition entre périodes glaciaires et interglaciaires MaP#14

On s’intéresse, ici, à l’alternance des périodes glaciaires et interglaciaires. Pour cela, il faut parler de l’évolution des paramètres orbitaux de la Terre, ce qu’on appelle des paramètres de Milankovitch. Mais, ces paramètres ne permettent pas d’expliquer, seul, les différences de températures observées dans le passé récent. On s’intéresse donc aux rétroactions de notre système climatique (au temps longs). Une dernière partie est consacrée à un des arguments fallacieux les plus souvent utilisés par les climato-dénialistes. Ce qui apprend à y répondre mais aussi comment on peut manipuler certaines idées.
Article source Shakun et al. (2012), malheureusement un article de Nature qui n’est pas en accès libre (en tant que scientifique, je trouve ça inadmissible la façon dont fonctionne les revues… ) http://www.nature.com/nature/journal/v484/n7392/full/nature10915.html
Un vieux c’est pas sorcier sur le sujet pour ceux qui aiment :) https://www.youtube.com/watch?v=-LObjnPMdgA (c’est surtout la fin qui recoupe avec ce que je raconte dans cette vidéo).

"A Brief Guide to the Last Glaciation" How did the North Sea develop? This piece develops the history of the ice sheets over Britain and Europe. This theory uses all the most recent technical data available, and comes up with a course of prehistoric modification of the British landscape that is not recognised by academic circles at this time.
A more detailed account is being developed, giving evidence and reasoned calculations for the processes involved.

Reading up on the #Cordilleran ice sheet, which is/was the ice sheet on the west coast of North America during the current period of #glaciation (from 2,580,000 years ago to present.)
#Wikipedia's article has an uncited section about #Refugia which includes a possibly controversial statement - needs tagging:
"…evidence of ice-free refugia above present sea level north of the Olympic Peninsula has been refuted by genetic and geological studies since the middle 1990s."
🟢 #GLACIATION at the #ENCRYPT Final Event in Athens
Yesterday, Mpampis Chatzimallis presented the GLACIATION EU project at the ENCRYPT Project Final Event, during the afternoon session focused on related #HorizonEurope projects.
His presentation showcased GLACIATION’s work on privacy-preserving, cross-border data collaboration, and the technical and governance frameworks that enable secure data sharing in complex environments.

Today, the GLACIATION Project is joining the Final Event of the ENCRYPT Project, held in Athens and accessible online.
During the afternoon session dedicated to related EU initiatives, #GLACIATION will outline its approach to supporting cross-border data collaboration and privacy-preserving technologies.
The event brings together stakeholders from research, policy, and industry to discuss the future of secure data sharing in #Europe.
Small Waterbodies Of Large Conservation Concern - Towards An Integrated Approach To More Accurately Measuring Surface Water Dynamics

“HIGHLIGHTS
• Hydrologic models were used to assess remotely sensed surface water estimates.
• The accuracy of satellite surface water estimates diminished for waterbodies < 2 ha.
• Vegetation reduces accuracy of surface water detection, especially during wet years..."

Scientists are coming closer to understanding the period of time during Marinoan period. This was about 720 million years ago and the earth is called "snowball earth' during this time. The period lasted somewhere between 4 and 15 million years ago. Scientists have been trying to narrow the time period down. Now by using isotopic dating of ash layers this has been narrowed to it lasting 4 million years.

Grand day in the Mull hills yesterday. Here are some superb ice-moulded ridges of quartz gabbro (ring dyke? of Centre 2, Paleocene) just south of Mam Clachaig. A' Chioch (mountain on left) and Beinn Fhada (right) in distance. #Mountains #Mull #Geology #Glaciation
Excellent visit earlier this week to Torosay Sand Limited's gravel quarry in eastern Mull. Most of the quarry consists of bedded gravel and sand deposited by glacial melt rivers around 16 to 15 thousand years ago when most of Scottish glacier ice melted away. But these are overlain by a couple of meters of grey till produced by local Mull glaciers during the "Loch Lomond Readvance" when ice grew again in western Scotland between about 13000 and 11700 years ago. #Geology #Glaciation #Mull
