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.
