FS Poseidon PO534
|Ship name (ship code)||FS Poseidon (06PO)|
|Cruise period||2019-05-01 — 2019-05-28|
|Port of departure||Bremerhaven, Germany|
|Port of return||Bremerhaven, Germany|
|Objectives||This cruise relates to the EU project: "Strategies for Environmental Monitoring of Marine Carbon Capture and Storage" STEMM-CCS.
1. Develop and test new sensitive and robust subsea monitoring technology, which is indicative for subsea C02 leakage. New technology: lab-on-a-chip, optodes, membrane inlet mass spectrometry, (multibeam)echosounder quantification.
2. Tests are conducted under a controlled C02-release experiment at Goldeneye (https://www.youtube.com/watch?v=FteAvlLEvzk).
3. Porewater geochemistry, benthic flux measurement, pelagic water column monitoring provide data for quantitative interpretation of C02-induced biogeochemical changes by numerical modelling to improve best practice guides for CCS integrity monitoring.
4. Hydroacoustic water column imaging and atmospheric CH4 and C02-measurements above abandoned wells in the North Sea provides statistical sound carbon flux estimates from 'leaky wells' into the North Sea and atmosphere.
