Our view of the sea floor is at present strongly biased towards muddy areas simply because we cannot sample sandy areas effectively. Vibrocoring is the only effective way of coring sand-rich parts of the ocean floor. This would be the only vibrocorer worldwide that can operate in water depths greater than 4,000 meters, and the only vibrocorer available for scientific projects worldwide that operates deeper than 2,000 meters. It would provide the only effective tool for sampling large areas of the ocean floor. The ROV-based vibrocorer can also take very precisely located samples (of sand or mud) in a wide range of water depths down to 6,000 m. This ability to take precisely located cores (whose context was well understood due to sea floor mapping using other technology during the ROV dive) would also enable a wide range of marine science. The design for the ROV-based vibrocorer has been provided by the Monterey Bay Aquarium Research Institute in California. This has resulted in a substantial cost saving. MBARI have previously built three ROV-based vibrocorers that have taken many hundreds of cores in and around the Monterey Canyon offshore California. This ROV based vibrocoring technology is therefore low risk because it has been already tried and tested by MBARI.

我们对海底的看法目前强烈偏向于泥泞的地区，因为我们不能有效地对沙质地区进行采样。振动取心是在海底富砂区域取心的唯一有效方法。这将是世界上唯一一个可以在水深超过4000米的地方工作的振冲器，也是世界上唯一一个可以在水深超过2000米的科学项目中工作的振冲器。它将是对大面积海底取样的唯一有效工具。基于rov的振冲器还可以在水深6000米的大范围内非常精确地定位样品（沙子或泥浆）。这种精确定位岩心的能力（由于在ROV潜水期间使用其他技术进行海底测绘，因此可以很好地了解岩心的背景）也将使广泛的海洋科学成为可能。这种基于rov的振动器的设计是由加州蒙特利湾水族馆研究所提供的。这大大节省了成本。MBARI之前已经建造了三个基于rov的振动器，在加利福尼亚州近海的蒙特利峡谷及其周围采集了数百个岩心。因此，这种基于ROV的振冲技术风险很低，因为MBARI已经对其进行了试验和测试。
