My project consists of investigating the different pockmark systems (e.g. crater-like depressions formed by upward transport of fluid through the unconsolidated sediment column) located in Lake Thun, Switzerland. In contrast to the marine realm, pockmark systems in lakes are much less investigated. By using a multidisciplinary approach (sedimentology, geology, biogeochemistry, and microbiology), we aimed to better understand the mechanism of formation of these pockmarks and quantify their potential influence on the lake hydrological and biogeochemical budget.
The financial support from CH-QUAT allowed me to participate in a 2-day conference (“Pockmarks et Ecosystèmes Benthiques”, Paris) specialized on pockmarks. During this conference, I have presented my research in front of many researchers from different fields, as well as participated in workshops during which we brought together our knowledge to identify the proxies that can be used to investigate pockmarks in marine and lacustrine environments. Thanks to the CH-QUAT and this conference, I have received relevant inputs that will be useful to develop my project further.
