Analyzing Archive Transit Multibeam Data for Nodule Occurrences

Journal of Marine Science and Engineering
We 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.

Subsidence of Artificial Reefs with Bamboo Foundations on a Soft Seabed

Applied Sciences
The 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.
