Estimation of Polymetallic Nodule Abundance Based on Seafloor Photography
Journal of Marine Environmental EngineeringIn this study, we aim to enhance the precision of estimating polymetallic nodule resources in the Western Pacific Ocean by employing a traditional deep-sea camera method supported by sampling. A series of image pre-processing techniques are applied, and an equation is developed to determine the weight and surface area of the nodules.

Megabenthic ecology of abyssal polymetallic nodule fields [PDF]
, 2019 Abyssal polymetallic nodule fields constitute an unusual deep-sea habitat. The mix of soft sediment and the hard substratum provided by nodules increases the complexity of these environments, and is thought to promote the occurrence of some of the most biologically diverse seafloor assemblages in the abyss.

Technical and Economy Study of Polymetallic Nodules Seabed Mining
2014At present there are many proposals on individual technical devices suitable for deep-sea mining of polymetallic nodules. Now is the time to define elements of the system of mining. The structure of such a system may consist of one or more vessels at the sea level, one or more mining collectors moving on the ocean floor, buffers, and vertical pipes and
