A 3.5 kHz or chirp sub-bottom profiling survey is widely used in the marine geological and engineering purpose exploration. However, swells in the sea degrade the quality of the survey data. The horizontal continuity of profiler data can be enhanced and the quality can be improved by correcting the ...

탐사장비는 무엇으로 구성되는가? | 5 kHz 천부지층탐사자료이며, 자료취득변수는 Table 1에 나타내었다. 탐사장비는 음원과 수신장치 역할을 동시에 수행하는 트랜스듀서(transducer)와 트랜시버(tranceiver)로 구성된다. 3. | |
해저면 신호의 진폭이 작기 때문에 나타나는 결과는? | 8d 에는 보정 결과를 나타내었다. 해저면 신호가 상대적으로 약한자료에 대하여 개별 트레이스에 대해 3가지 형태의 자료로부터 구한 해저면 위치들은 원자료와 엔벨로프자료에서는 해저면이 아닌 하부의 지층을 찾은 경우가 많았다(Fig. 8). | |
현장탐사에서 발파시간간격은? | 5 kHz 천부지층탐사 디지털 자료는 A/D (analog-to-digital) 변환기를 장착한 PC기반의 KDAPS (KIGAM (Korea Institute of Geoscience and Mineral Resources) Data Acquisition and Processing System)로 기록하였다. 발파시간간격은 0.5 s의 등시간 간격이다. 탐사속도를 ~9 km/hour (~5 knots)로 유지하여 발파간격은 ~1. |
