Landscapes Live

Landscapes Live is a weekly online seminar series opened to the international scientific community interested in various aspects of geomorphology. Every week, we will post here a link to a Zoom meeting. If you intend to join, have a login that allows you to be fully identified. The talk is every Thursday, starting at 2pm GMT.

Check your local time here – 2pm GMT = 3pm in London / 4pm in Paris-Berlin / 5pm in Moscow / 7.30pm in Delhi / 10pm in Beijing / 10am in New-York / 7am in Los Angeles / way too early in Hawaii ! ).

“Sublimation as a geomorphic process on Mars”

Abstract: Our experience on Earth points to water as one of the main agents of landscape denudation – in its liquid state mainly by fluvial erosion and sub-glacial erosion. However, liquid water is rare on planetary surfaces other than the Earth. I will be talking about how sublimation can be a landscape forming process and how its action on Mars has led to some surprising landforms, and other landforms that closely resemble those carved by liquid water on Earth.

“Appalachian pasts, Arctic futures: permafrost landscape dynamics”

Abstract: What happens to permafrost landscapes when the climate heats up? Today, high latitudes face amplified warming and permafrost thaw, leading to erosion, carbon release and ecosystem disturbance, and predicting the location and magnitude of such disturbance is a top priority for Arctic communities and climate modelers alike. I argue we can make better predictions by probing sedimentary records from past warming events in unglaciated Appalachia, where permafrost thaw and ecosystem change occurred thousands of years ago and is recorded in sedimentary archives in headwater catchments and bogs. I show how digital terrain analysis in both Appalachia and Alaska, geophysical imaging, isotope and bulk geochemistry and pollen allow me to connect erosion rates and styles to  past climate conditions.

“Estimating mass loss from pebble shape”

Abstract: One important question in sedimentology is the mass loss of pebbles due to erosion. In some cases it is possible to track the mass loss process, however, this may not always be the case. We present a mathematical theory which suggests that from measurements of current shape descriptors and some information on the formative process, the original mass of pebbles may be efficiently estimated.

“Flow of southeastern Tibet across a steady-state topography”

Abstract: The Tibetan Plateau is Earth’s most important topographic feature, which controls the strength of the Asian Monsoon. Most current models predict that the plateau has been steadily growing southward for tens of millions of years. Using a new, high resolution thermochronological dataset from the deep gorges of the Salween and Mekong rivers, we postulate that the shape of the southeastern margin of the plateau has remained unchanged for the last 10 Myr, while vast volume of rocks have continued to flow across it. Our finding agrees very well with a wide range of other, independent geological and geophysical data and has implications for our understanding of the evolution of Asian climate and biodiversity.
