The aim of this project is to unveil the microbial biodiversity, novel metabolic capabilities and chemosynthetic primary production of subsurface ecosystems, such as those found in caves. Leveraging a powerful blend of geospatial, molecular and biogeochemical approaches this project expects to identify the microbial basis of subsurface biogeochemical processes driving the earth’s major elementary cycles. Expected outcomes include a predictive framework to assess and upscale the impact of these microbial communities on the environment. Benefits include predicting and responding to climate risks, such as the desertification of agricultural soils, by uncovering how microorganisms respond to nutrient and carbon depletion.

该项目的目的是揭示地下生态系统（例如在洞穴中发现的生态系统）的微生物多样性、新颖的代谢能力和化学合成初级生产，该项目希望利用地理空间、分子和生物地球化学方法的强大结合来确定地下生态系统的微生物基础。驱动地球主要基本循环的地下生物地球化学过程的预期结果包括评估和升级这些微生物群落对环境的影响的预测框架。通过揭示微生物对养分和碳消耗的反应，应对农业土壤荒漠化等气候风险。
