During the Svalbard field campaign, the MISO team tested a gas flux chamber system designed to measure greenhouse gas emissions directly from the ground in remote Arctic environments, with minimal maintenance requirements.
- Greenhouse gases released from the soil are captured inside the chamber and circulated through the tubing.
- After a predefined measurement period, the chamber is flushed with ambient air before being closed again and the sequence is repeated.
- Gas concentrations are measured using the K96 sensor, and data are stored locally.
Over time, the system can be equipped with wireless communication, enabling data retrieval by UAVs and supporting fully autonomous operation in hard-to-access locations.
⚠️
- Installing the chamber in Arctic conditions proved challenging due to frozen soil, which required preparing the ground using a hammer and chisel before lowering the ground pipe.
- Achieving a reasonably airtight seal between the frozen soil and the ground pipe was difficult, highlighting an important area for future design improvements.
