TOMODEC. High resolution seismic tomography of Deception Island (Antarctica), and modelling of seismo-volcanic sources. Bathymetryc data and derived products.

In January 2005 a multi-parametric international experiment was conducted that encompassed both Deception Island and its surrounding waters. This experiment used as main platforms the Spanish Oceanographic vessel 'Hesperides', the Spanish Scientific Antarctic base 'Gabriel de Castilla' at Deception Island and four temporary camps deployed on the volcanic island. This experiment allowed us to record active seismic signals on a large network of seismic stations that were deployed both on land and on the seafloor. In addition other geophysical data were acquired, such as: bathymetric high precision multi-beam data, and gravimetric and magnetic profiles.
During the whole period of the experiment a multi-beam sounding EM120 was used to perform bathymetric surveys. The characteristic of this sensor permitted to reach up to 11.000 m b.s.l. In table 2 we provide some of its main characteristics.
During the experiment different bathymetric profiles were performed with this equipment outside of Port Foster. Some of these images already have provide an accurate vision of the region, and were used to estimate the real size of the water column locate below each shoot. Additional information of these data could be found in the Lamont-Doherty Earth Observatory at IEDA Marine Geoscience Data System (http://www.marine-geo.org/). It is possible to access the summary of downloads that were made of these data and documents at http://www.marine-geo.org/about/downloadreport/person/Ibanez_Jesus/2016A.

2005年1月，一项多参数国际实验在欺骗岛（Deception Island）及其周边海域开展。本次实验以西班牙海洋考察船"赫斯佩里德斯号"（Hesperides）、位于欺骗岛的西班牙南极科学考察基地"加夫列尔·德·卡斯蒂利亚站"（Gabriel de Castilla），以及部署在这座火山岛上的4座临时营地作为核心作业平台。实验依托布设于陆地与海底的大规模地震台站网络，记录到了主动地震信号。此外还采集了多类地球物理数据，包括高精度多波束测深数据、重力与磁法剖面数据。

实验全程采用EM120多波束测深系统开展海底地形测量。该传感器的性能上限可达11000米水深（b.s.l.为below sea level的缩写，即海平面以下）。表2列出了该传感器的部分核心参数。

实验期间，研究团队使用该设备在福斯特港（Port Foster）外侧完成了多组海底地形剖面测量。其中部分测绘图像已精准呈现了该区域的地貌全貌，并被用于估算每条测线下方水体柱体的实际尺度。这些数据的补充信息可在拉蒙特-多尔蒂地球观测站下属的IEDA海洋地球科学数据系统（IEDA Marine Geoscience Data System，http://www.marine-geo.org/）获取。用户可通过链接http://www.marine-geo.org/about/downloadreport/person/Ibanez_Jesus/2016A 查阅这些数据与文档的下载汇总报告。
