Data collection and database management

Support for data collection within WP1, WP2 and WP3.

WP1: Monthly monitoring of a pilot site (Chavoley) for sediment gas measurements and water sampling aimed at identifying bacterial communities (MOB) using qPCR.

WP2: Collection of short sediment cores in lowland lakes (Bugey) and high‑altitude lakes (Sentinel Lakes Network).

WP3: Assistance with data collection to feed watershed and lake models used to simulate carbon inputs and their fate within lakes.

Regional synthesis of soil‑erosion dynamics in the Alps during the Holocene and its impact on carbon export and burial

This work aims to synthesise existing palaeolimnological data from Alpine and peri‑Alpine lakes in France and beyond, in order to assess lateral carbon exports and its accumulation in lakes throughout the Holocene. The objective is to determine how human disturbances have shaped the lacustrine carbon cycle over millennial timescales—an aspect still largely overlooked in carbon‑cycle research. By integrating multiple sedimentary proxies, the study will provide a comprehensive understanding of the interactions between lacustrine carbon stocks and sources, soil erosion, and associated transformations within watersheds. The harmonised dataset produced will also support the DEEP‑C project’s modelling efforts to simulate large‑scale Holocene carbon fluxes and stocks.

Quantifying the role of lentic ecosystems (gravel pits, ponds, natural lakes, reservoirs, etc.) in the carbon cycle (production, emission, sequestration, greenhouse‑gas transfer) and identifying the key processes that determine the fate of organic carbon in these freshwater systems.

This work has two main components. First, it involves analysing the monthly datasets collected since 2024 at four pilot sites encompassing both natural and artificial lentic systems. These datasets include organic‑matter characterisation, sediment GHG production, water‑column concentrations and atmospheric emissions, trophic‑network incorporation assessed through stable‑carbon‑isotope analyses, and associated environmental parameters. Second, the work includes coordinating and contributing to field campaigns and laboratory analyses across a broader set of sites in 2026–2027. It also entails conducting a comprehensive review of existing data from the scientific literature and from consortium partners, and disseminating the findings within the FairCarbon programme.

Vulnerability of sedimentary carbon stocks and long‑term compensation of lacustrine greenhouse gas emissions over centennial to multi‑centennial scales

My PhD investigates the fundamental role of aquatic environments in the global carbon cycle. For the first time, this work provides a coupled analysis of three key mechanisms: CO₂ emissions, methane release, and carbon sequestration in lake sediments. By examining these processes over long timescales—spanning several decades to centuries—this research aims to decipher the historical biogeochemical dynamics of lake ecosystems. The goal is to determine how human pressures, particularly eutrophication and climate warming, have altered the capacity of these systems to store or release carbon. The scientific challenge is considerable: understanding how lakes respond to recent environmental changes is essential to accurately evaluate their true contribution to global greenhouse gas emissions
