The NERC-funded QICS controlled CO2 release experiment (located offshore Oban, Scotland) mimics the formation of a new CO2 seep in the marine environment. At the site, CO2 is injected at an onshore wellhead, and a stainless steel pipe transports the CO2 under the seabed. Approximately 350 m offshore, the CO2 is released through a perforated screen into the 12 metres of overlying marine sediment, which is at approximately 10 metres water depth. During spring/summer 2012, 4.2 tonnes of CO2 was released at the QICS experimental site. In order to establish stakeholder views on the research priorities for the site, consultations for three 'audiences' were performed via online questionnaires. These 'audiences' were: 1. QICS research community: Researchers actively involved in the QICS project were asked to complete an online questionnaire. The questionnaire aimed to gather participants' reflections of the QICS CO2 injection experiment in Summer 2012, and also to consult on the scientific priorities for possible future activity at the site. 2. CCS (storage) research community: The international CCS research community (specifically, researchers working on aspects of CO2 storage) were consulted via an online questionnaire distributed by the IEAGHG storage network mailing list in June 2013. The survey aimed to gather their reflections of the QICS project, and to consult on the scientific priorities for possible future activity at the site. The survey had 24 respondents with a broad range of expertise and representing both industry and research organisations from 10 countries. 3. Technology industry: Technology industries were consulted via an online questionnaire. The survey aimed to gather consult on the scientific priorities for science and technology development at possible future activity at the site, and also to scope potential interest from technology developers. For each of these consultations there is a report (presenting a synthesis of the survey responses) and also the dataset for all three surveys. All of these files are confidential.
