Sub-seabed CO2 Storage: Impact on Marine Ecosystems (ECO2) (A 7th Framework Programme EU project) aboard R/V Helmer Hanssen

Chief Scientist: Stefan Bünz


The ECO2 project sets out to assess the risks associated with the storage of CO2 below the seabed. Carbon Capture and Storage (CCS) is regarded as a key technology for the reduction of CO2 emissions from power plants and other sources at the European and international level. The proposed project will assess the likelihood of leakage and impact of leakage on marine ecosystems. As part of the ECO2 project, cruise CAGE13-3 intend to acquire a 3D seismic volume (which will act as monitor along with the 3D cube collected in 2011) from the Snøhvit carbon capture area. In addition, we will repeat some of the lines twice and in reversed direction in order to study the repeatability of the P-Cable acquisition for monitoring purposes. The primary objective of the hydrological and biogeochemical sampling in the Snøhvit area is to study any possible effects of a Carbon Capture and Storage (CCS) site on the water column and on the bottom sediment.
