Raw high-resolution single- and dual-channel seismic field data from the 2006 MERC I Eilat-Aqaba survey

The first high-resolution seismic survey, MERC I, in the area offshore Eilat in the northern Gulf of Aqaba was conducted from 29 October to 16 November 2006 and included the acquisition of 261 seismic lines with a total length of 426 km. The survey was carried out in two phases: deep survey (water depths of 100–700 m) onboard the R/V Etziona and a shallow phase (water depths of less than 100 m) onboard a fishing vessel called Danny-Boy. The high-resolution geophysical survey used a GeoResources GeoSparker200 seismic source generated by electrical spark at energies of 300–1000 J and seismic frequencies of 200–3000 Hz. During the deep survey, the system used two hydrophone arrays (i.e. dual-channel), one towed parallel to the sparker, and the other offset about 50m attempting to receive more seismic energy across steep slopes. In the shallow survey only one hydrophone array (i.e. single-channel) was towed parallel to the sparker. The seismic acquisition parameters are described in the associated documents. Funding was provided through the U.S. Agency for International Development Middle East Regional Cooperation program (MERC) under contracts TA-MOU-05-M25-004 and TA-MOU-08-M29-036.

亚喀巴湾北部埃拉特近海海域的首次高分辨率地震勘探——MERC I，于2006年10月29日至11月16日实施，共采集261条地震测线，总长度达426千米。本次勘探分为两个阶段：深水勘探阶段（作业水深100~700米）在R/V Etziona号科考船上开展，浅水勘探阶段（作业水深小于100米）在名为"Danny-Boy"的渔船上进行。本次高分辨率地球物理勘探采用GeoResources公司GeoSparker200电火花震源，激发能量为300~1000焦耳，地震信号频率范围为200~3000赫兹。深水勘探阶段，该系统配备两套水听器阵列（即双通道）：一套与电火花震源并行拖曳，另一套偏移约50米，以在陡坡区域获取更多地震能量。浅水勘探阶段仅采用一套与电火花震源并行拖曳的水听器阵列（即单通道）。地震采集参数详见配套文档。本项目由美国国际开发署（U.S. Agency for International Development）中东区域合作计划（MERC）通过合同TA-MOU-05-M25-004与TA-MOU-08-M29-036提供资助。
