在衣阿华州西南地区使用了 NimbusES1210F12道信号增强地震仪和 G724S 数字记录器,成功地采集到自地面至地下1800米深处的高分辨率地震反射数据。一个三人野外小组使用一辆汽车,每天可采集到0.8公里(0.5英里)的6次 CDP 叠加数据,并且在当天晚上就可用一台轻便的微型计算器进行处理。在野外工作中数据存贮在简易盒式磁盘上,然后被转录到按 SEG 格式记录的9轨磁带上,以便进行标准的勘探处理。事实证明,当采用最新研制的 Nimbus
The NimbusES1210F12 Road Signal Seismograph and the G724S Digital Recorder were used in the southwestern region of Iowa to successfully capture high resolution seismic reflection data 1800 meters deep from the ground to the surface. A three-man field team used a car to collect 6 CDP overlays of 0.8 km (0.5 miles) daily, and was able to process it with a portable micrometer that same night. In the field work data is stored on a simple cartridge and then transcribed to 9-track tape recorded in SEG format for standard exploration. It turns out that when using the newly developed Nimbus
