1. What contributions have the authors mentioned in the paper "Hydrophone array optimization, conception, and validation for localization of acoustic sources in deep-sea mining" ?
In this study, a 3-D prototype acoustic array to perform this localization and quantification is designed, built, and deployed at sea for validation of its localization capacities.. The design method performs a two-step study to define the array shape and select the hydrophone arrangement over it, under harsh constraints.. Thus, this design procedure provides an efficient underwater acoustic array for monitoring deep-sea mining, the localization capacities of which are validated in a real-life setting.

![Fig. 5. The 385 different CD configurations in the mean MSL/mean FWHM space. −− represents the threshold given for the FWHM in Section II-A; the MSL threshold cannot be represented because it is too low (−8 dB) compared to the values obtained ([−6;−3] dB). Each represents one of the 385 tested configurations. represents the configuration that gives the best performance from among these 385. • gives the performance of a new configuration from the best array with its middle circle rotated by 1◦ steps, whereas + gives the performance of a new configuration from the best array with its middle circle translated by 2-cm steps.](/figures/fig-5-the-385-different-cd-configurations-in-the-mean-msl-1dc97xat.webp)
