In-situ monitoring

Definition

In-situ monitoring refers to the process of observing and measuring environmental parameters directly in their natural location, rather than in a laboratory or controlled setting. This method is crucial for accurately assessing changes in ecosystems, particularly in areas experiencing significant environmental shifts like thawing permafrost. By collecting real-time data on factors such as temperature, moisture, and gas emissions, researchers can better understand the dynamics of biogeochemical processes occurring in situ.
