Early observations from the Perseverance rover suggested a deltaic origin for the western fan of Jezero crater only from images of the Kodiak butte. Here, we use images from the SuperCam Remote Micro‐Imager and the Mastcam‐Z camera to analyze the western fan front along the rover traverse, and further assess its depositional origin. Outcrops in the...

Continental weathering and erosion are fundamental components of global geochemical cycles on earth, facilitating the transfer of atmospheric CO₂ to sedimentary reservoirs through alteration of silicates and transfer of organic carbon. In the Himalayas, a region characterized by kinetically limited weathering, the interplay between monsoon intensit...

Seafloor methane emissions can affect Earth’s climate and ocean chemistry. Vast quantities of methane formed by microbial decomposition of organic matter are locked within gas hydrate and free gas on continental slopes, particularly in large areas with high sediment accumulations such as deep-sea fans. The release of methane in slope environments h...

The tidal prism, or the volume of water exchanged from the sea to an estuary from mean low to mean high tide, influences system hydrodynamics and ecological functioning. Since 1884, the tidal prism in Morro Bay, California has been estimated to be decreasing over time due to sedimentation from upstream practices. What is the current tidal prism in ...

Comprendre l’impact des perturbations climatiques passées sur les environnements continentaux est crucial pour mieux anticiper le futur de notre Terre. Cette thèse contribue à l’effort collectif des études concernant la Transition Éocène-Oligocène (TEO) au prisme des environnements continentaux du Fossé Rhénan (FR). C’est une période de ~790 ka qui...

Mass movements and delta collapses are significant sources of tsunamis in lacustrine environments, impacting human societies enormously. Palaeotsunamis play an essential role in understanding historical events and their consequences along with their return periods. Here, we focus on a palaeo event that occurred during the Younger Dryas to Early Hol...

Le Paléogène du Bassin de Paris est un cas extrêmement intéressant de système « Source-to-Sink » : les bassins versants amonts sont des plateaux étagés de faible altitude soumis à une intense altération chimique, évoluant à un système en dépôt faiblement subsident (200m en 35Ma) constitué de grands domaines palustro-lacustres et de domaines marins ...

This thesis aimed to provide deeper insights the effectiveness of hypersaline lacustrine settings and microbial mats as palaeoenvironmental archives, while attempting to further understand the spatial complexities of the depositional and sub-depositional settings of saline lakes and characteristics of microbial mats within them. To achieve this, ke...
