Analyzing Archive Transit Multibeam Data for Nodule Occurrences
Journal of Marine Science and EngineeringWe show that analyzing archived and future multibeam backscatter and bathymetry data, in tandem with regional environmental parameters, can help to identify polymetallic nodule fields in the world’s oceans.

Geometric and Radiometric Correction of Multibeam Backscatter Derived from Reson 8101 Systems [PDF]
, 2002 A common by-product of multibeam surveys is a measure of the backscattered acoustic intensity from the seafloor. These data are of immense interest to geologists and geoscientists since maps of the acoustic backscatter strength can be used to infer ...

A Suite of Field Manuals for Marine Sampling to Monitor Australian Waters
Frontiers in Marine Science, 2019 One of the main challenges in assessing marine biodiversity is the lack of consistent approaches to monitor it. This threatens to undermine ocean best practice in marine monitoring, as it impedes a reduction in the bias and variance of sampled data and ...

Subsidence of Artificial Reefs with Bamboo Foundations on a Soft Seabed
Applied SciencesThe design of artificial reefs must be based on the criteria of both durability and serviceability. In this respect, the seabed subsidence rate related to the weight of the reefs and of their foundation system should be limited.
