Ziel der Reise / Objectives of Cruise:
The POS534 research cruise relates to the EU project: "Strategies for Environmental Monitoring of Marine Carbon Capture and Storage" STEMM-CCS. Contributions to the main aims of STEMM-CCS (i.e. WP 4, http://www.stemm-ccs.eu/work-packages): (1) Develop and test new sensitive and robust subsea monitoring technology, which is indicative for subsea CO2 leakage. New technologies: optodes, membrane inlet mass spectrometry, (multibeam)echosounder quantification (2) Tests were conducted under a controlled CO2-release experiment at Goldeneye (https://www.youtube.com/watch?v=FteAvILEvzk ). (3) Porewater geochemistry, benthic flux measurement, pelagic water column monitoring provide data for quantitative interpretation of CO2-induced biogeochemical changes by numerical modelling to improve best practice guides for CCS integrity monitoring. (4) Hydroacoustic water column imaging and atmospheric CH4 and CO2-measurements above abandoned wells in the North Sea provides statistical sound carbon flux estimates from "leaky wells" into the North Sea and atmosphere.
