Temperature and conductivity fluctuations caused by the hydrothermal emissions released during the degasification stage of the Tagoro submarine volcano (Canary Islands, Spain) have been analysed as a robust proxy for characterising and forecasting the activity of the system. A total of 21 conductivity-temperature-depth time series were gathered on a regular high-resolution grid over the main crater of Tagoro volcano. Temperature and conductivity time series, as manifestations of stochastic events, were investigated in terms of variance and analysed by the Generalised Moments Method (GMM). GMM provides the statistical moments, the structure functions of a process whose shape is an indicator of the underlying stochastic mechanisms and the state of activity of the submarine volcano. Our findings confirm an active hydrothermal process in the submarine volcano with a sub-normal behaviour resulting from anti-persistent fluctuations in time. Its hydrothermal emissions are classified as multifractal processes whose structure functions present a crossover between two time scales. In the shorter time scale, findings point to the multiplicative action of two random processes, hydrothermal vents, which carries those fluctuations driving the circulation over the crater, and the overlying aquatic environment. Given that both temperature and conductivity fluctuations are nonstationary, Tagoro submarine volcano can be characterised as an open system exchanging energy to its surroundings This research was funded by FEDER and the Spanish Ministry of Economy and Competitiveness through the VULCANO-II project (CTM2014-51837-R) and for the Spanish Institute of Oceanography through the VULCANA-I (IEO-2015-2017) project, both projects led by the Spanish Institute of Oceanography (IEO), and by Fundación CajaCanarias-LaCaixa through project Cyclovent (2019SP18). Moreover, the Swiss company ORIS Höltsein 1904 funded the scholarship of one of the authors in the Spanish Institute of Oceanography facilities making possible the data preparation, data assessment and training With the institutional support of the ‘Severo Ochoa Centre of Excellence’ accreditation (CEX2019-000928-S) Peer reviewed 2021-09-16T06:42:17Z 2021-09-16T06:42:17Z 2021-09 artículo http://purl.org/coar/resource_type/c_6501 Geosciences 11(9): 374 (2021) CEX2019-000928-S http://hdl.handle.net/10261/250308 10.3390/geosciences11090374 2076-3263 http://dx.doi.org/10.13039/501100011034 http://dx.doi.org/10.13039/501100011033 http://dx.doi.org/10.13039/501100003329 http://dx.doi.org/10.13039/100012000 en #PLACEHOLDER_PARENT_METADATA_VALUE# info:eu-repo/grantAgreement/MINECO/Plan Estatal de Investigación Científica y Técnica y de Innovación 2013-2016/CTM2014-51837-R https://doi.org/10.3390/geosciences11090374 Sí open Multidisciplinary Digital Publishing Institute
