Zusammenfassung |
An adequate understanding of aquatic carbonate systems require high quality in-situ measurements with sufficient temporal and spatial resolution. Within the frames of the ongoing FixO3 project and as a pre-study for a deep water fixed observatory deployment 8 different technologies to measure pCO2 and pH were compared in-situ using the Koljoefjord cabled observatory (https://www.youtube.com/watch?v=0M9Z8BWzrkA) as the backbone. This presentation will discuss obtained results taking into account challenges imposed by fouling and the difficulty to collect representative reference samples in this and less dynamic environments. |
