• Increase of broadband acoustic images (BAI) collection
• Detailed spectral information
• But curse of dimensionality, limited availability of labeled samples and taxa mixing
• Unsupervised classification approaches to BAI big data challenge
• New methodologies,methodologies,( softwares ,,( computers and common reference datasets for benchmarking
• Hyperspectral image community legacy
• First results of unsupervised classifications of BAI near an offshore windmill in the Bay of Biscay BoB France, EchoSonde project)
