Sediment grab sampling with marine benthic fauna bycatch

Undertake sediment grab sampling (marine benthic fauna maybe included not specifically targeted returned to the seabed) in association with side scan sonar and geotechnical surveys completed for potential offshore drill sites, subsea pipline alignments and offshore platform locations.

为适配潜在海上钻井场址、海底管线走向及海上平台场址的勘测需求，同步开展侧扫声呐（side scan sonar）与岩土工程勘察（geotechnical surveys）作业，并配套实施沉积物抓斗取样（sediment grab sampling）；该取样作业的沉积物样本中可能包含海洋底栖生物（marine benthic fauna），但未将其作为专门采样目标，作业完成后将采样抓斗返还海床。
