| Summary: | Deception Island volcano (Antarctica) is one of the most closely monitored and studied volcanoes on the region. In January 2005, a multi-parametric international experiment was conducted that encompassed both Deception Island and its surrounding waters. We performed this experiment from aboard the Spanish oceanographic vessel ‘Hespérides’, and from five land-based locations on Deception Island (the Spanish scientific Antarctic base ‘Gabriel de Castilla’ and four temporary camps). This experiment allowed us to record active seismic signals using a large network of seismic stations that were deployed both on land and on the seafloor. In addition, other geophysical data were acquired, including bathymetric high precision multi-beam data, and gravimetric and magnetic profiles. To date, the seismic and bathymetric data have been analysed but the magnetic and gravimetric data have not. We provide P-wave arrival-time picks and seismic tomography results in velocity and attenuation. In this manuscript, we describe the main characteristics of the experiment, the instruments, the data, and the repositories from which data and information can be obtained.

He was the principal researcher for all of the Spanish projects involved in the experiment, and was a main researcher for the remaining projects. He was the advisor of A.D.-M., J.P., D.Z., J.A., and A.G.-Y., whose doctoral theses have contributed to the present database and to improving knowledge of Deception Island. He contributed to the structure and text of this manuscript, and prepared the figures. He coordinated data analysis and actively participated in the derived models and in the data storage. A.D.-M. actively participated in writing this manuscript, in the attenuation derived models, in data organisation, and in the storage of the data. J.P. actively participated in writing this manuscript, and in editing and improving the figures. Through her PhD thesis, she was responsible for all works associated with the attenuation models and provided these derived products. D.Z. actively participated in the success of the TOMODEC experiment, which formed the main part of her PhD thesis. She actively participated in all phases of the experiment, including the preliminary search for sites, the planning of the experiment, the field campaign, and the derivation of velocity seismic tomography of Deception Island. W.W. was responsible for the NSF project that provided OBSs to the experiment, and actively participated in the TOMODEC field campaign. He advised the velocity-derived models, including the 3-D seismic tomography. His support during the preparation phase of the experiment, during the experiment itself, and after the experiment was crucial to the creation of this high quality database. A.B. was, together with W.W., responsible for the successful use of OBSs, participating in their deployment and data quality control. He participated in on-land activities during the experiment. He was actively involved in the derivation of structural velocity models of Deception Island. He was responsible for bathymetric data and prepared the high-resolution sea floor map of the region, which is necessary for any analysis using this database. He has performed a deep revision of the English version of this manuscript. J.A. was the co-advisor of the doctoral thesis of D.Z. He actively participated in the planning and development of the TOMODEC experiment and in the velocity derived models, including the determination of the first arrival, quality control, and the publications of these results. C.B. was the other principal researcher for the Spanish project KNOWAVES, together with J.M.I., which provided support for data storage and dissemination. She is responsible for the present and future policy of geophysical data dissemination and for the public diffusion strategy of experiments associated with our research group. A.G.-Y. actively participated in the production of derived attenuation models of Deception Island. She has improved and corrected the text of this manuscript and provided complementary information to complete the database. G.I. was responsible for the seismic stations deployed on land and for the construction of the seismic arrays used in this experiment. He actively participated in the planning and execution of the TOMODEC field campaign. He was responsible for the quality of seismic data and maintained a permanent presence during signal processing of seismic data. |
