2013-14: EMSO-Azores, Atlantic Ocean, Tour Eiffel Edifice, CISICS was deployed on top of the chimney. On 29/09/13 13:50, the instrument slid down the edifice so data after that date are not to be taken into account. There were no water sampling due to inlet clog. https://doi.org/10.17882/42980

2014-15: EMSO-Azores, Atlantic Ocean, Tour Eiffel Edifice, CISICS was deployed at the base of the chimney in a area where seepings are diffuses. https://doi.org/10.17882/48321
