TOMODEC. High resolution seismic tomography of Deception Island (Antarctica), and modelling of seismo-volcanic sources. SEISMIC DATA
Listed in NASA Earthdata CMR
The base of this experiment performed in Deception Island volcano was the generation of active seismic signals using the Spanish Oceanographic Research Vessel 'Hesperides' .
Description
Seismic signals were recorded on a temporary network of land seismometers on the volcanic island and of ocean-bottom seismometers (OBS) deployed on the floor of the flooded caldera (Port Foster) and in the Bransfield Strait around the island. Ninety-five on-land seismic stations and 14 OBSs were deployed.
They included 7 Lennartz Marslite seismic stations (covering 14 positions), four M24 instruments (covering 7 positions) and 11 seismic arrays (with 84 short period sensors, occupying a total of 101 different positions), all of them working in continuous recording mode. In order to provide a clear nomenclature of the different seismic stations, each type of sensor received different names. These seismic stations are: - Seismic Arrays Modules (A, B, C, E, F, G, H, J, K, L, M, N).

Each array module was used with different number of channels according to their position and use. Thus, Modules A, B and C were used with three component stations placed near the Spanish Base, the Argentinean Base and in Fumarole Bay; modules E, F contained a three component and 8 vertical seismometers; modules G and H with a three component and 9 vertical seismometers (during the second phase of shooting some of the vertical seismometers were shifted into a smaller configuration in order to be used to estimate the uppermost velocity structure under the array sites21); Array J with 11 vertical component seismometers; array K with a three component seismometer and 5 vertical seismometers in the first phase, and with 9 in the second phase in different places; arrays L and M with a three component and 9 vertical seismometers with no changes; array N with three vertical seismometers. - M24 (DE46, DE47, DE63, DE64, W15, W26, W27) - Marslite (W01, W04, W05, W06, W07, W10, W11, W12, W13, W14, W16, W17, W18, W23, W25) - OBS (S111, S112, S113, S114, S201, S202, S203, S204, S206, S207, S208, S209, S211, S213, S301, S302) - RADIO-TELEMETER STATIONS (FUM, OBS, PEN, BAS).
In the public access link a file display the full information of these seismometers including type of the system (arrays are named MalIAG), name of the unit, channels used, component of the seismometers (3C or V), latitude S (in degrees and minutes, and degrees, minutes and seconds), longitude W (in degrees and minutes, and degrees, minutes and seconds), UTM position East and North, elevation over the sea level, stating and end of the recording period and shooting phases recorded.
