Anthropogenic influence in the ocean can lead to poor environmental health of the seabed. For example, huge fish farms, designed to feed our exploding population, produce massive faecal pallets that sink to the deep. These causes stress to the health of the seabed and the organisms living in it. Sediment-profile imaging (SPI) cameras are widley used to assess anthropogenic influence and the health of the seabed. SPI cameras take pictures of the sediment-water interface. These pictures are used to determine the animal-sediment relationship, the oxygen penetration depth, bioturbation (particle and water displacement caused by animals) and the Benthic Habitat Quality. However, the major disadvantage of this technique is that by only looking at two dimensions of the sediment and ignoring the third one information get lost. Conclusions are reached based on incorrect assumptions. This NEXUSS project involves the improvement of the SPI camera to consider the third dimension of the sediment. Assessing the third dimension of the sediment requires to develop new and innovative techniques. This will be deployed from autonomous lander platforms to achieve a rapid and more accurate investigation of the seafloors' health condition.

海洋中的人为影响可能会导致海底环境健康状况不佳。例如，大型养鱼场，旨在养活我们爆炸式增长的人口，产生大量的粪便托盘，这些粪便托盘会沉入深海。这些都会对海床和生活在其中的生物的健康造成压力。沉积物剖面成像(SPI)相机广泛用于评估人类活动的影响和海底的健康状况。SPI相机拍摄沉积物-水界面的照片。这些图片被用来确定动物-沉积物的关系、氧气渗透深度、生物扰动(动物引起的颗粒和水的移动)和底栖生境质量。然而，这种方法的主要缺点是只观察沉积物的两个维度，而忽略了第三个维度的信息。结论是基于错误的假设得出的。NEXUSS项目包括改进SPI相机，以考虑沉积物的第三维度。评估沉积物的第三维度需要开发新的和创新的技术。这将从自主着陆器平台部署，以实现对海底健康状况的快速和更准确的调查。
