用于超浅水域的有源和无源近场水听器

本文的作者描述了一种在阿布扎比近海复杂的近地表区域结合主动和被动近场水听器测量的方法。

地震勘测可能会使近地表采样不足。这在阿布扎比近海尤其是一个挑战，那里复杂的近地表污染了地震图像。为了减轻这些影响，作者使用近场水听器 (NFH) 数据。NFH 位于每支气枪上方约一米处，旨在记录近场压力。

Active and Passive Near-Field Hydrophones Used in Ultrashallow Waters

The authors of this paper describe an approach that combined active and passive near-field hydrophone measurements in a complex near-surface area offshore Abu Dhabi.

Seismic surveys can leave the near-surface undersampled. This is particularly a challenge offshore Abu Dhabi, where a complex near-surface contaminates the seismic image. To mitigate these effects, the authors use near-field hydrophone (NFH) data. NFHs are positioned approximately a meter above each airgun and are designed to record near-field pressure.
