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.

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 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.

Morphological Variability of Submarine Mass Movements in the Tectonically–Controlled Calabro–Tyrrhenian Continental Margin (Southern Italy)

Geosciences, 2019
The analysis of high resolution morpho–bathymetric data on the Calabro Tyrrhenian continental margin (Southern Italy) enabled us to identify several morphological features originated by mass–wasting processes, including shallow gullies, shelf&

Data handling methods and target detection results for multibeam and sidescan data collected as part of the search for SwissAir Flight 111 [PDF]

, 1999
The crash of SwissAir Flight 111, off Nova Scotia in September 1998, triggered one of the largest seabed search surveys in Canadian history. The primary search tools used were sidescan sonars (both conventional and focussed types) and multibeam sonars ...

Seafloor Characterization from Spatial Variation of Multibeam Backscatter vs. Grazing Angle [PDF]

, 2001
Backscatter vs. grazing angle, which can be extracted from multibeam backscatter data, depend on characteristics of the multibeam system and the angular responses of backscatter that are characteristic of different seafloor properties, such as sediment ...
