Dear colleagues: My name is Daniel Patón and I live to thousands of kilometers far away of sea and cetaceans :-(. However, I am professor of Ecology in a small University in SW Spain, close to Portugal rounded of vultures, eagles, birds and incredible landscapes ;-). In my classes on numerical methods in ecology, the students use animal sounds from internet that we analyze mathematically. Usually, students are interested in birds but this year we are exploring other organisms. A group of students is preparing a work on cetaceans and we had localized a lot of species. However we do not find any sound file in WAV on these species: Balaenoptera_edeni Kogia_breviceps Kogia_sima Pontoporia_blainvillei Any of this list could send me sound files on these species?. We need the data in WAV for working on ultrasounds. As counterpart I can help in data analysis or any questions that require numerical methods (multivariate analysis, genetic algorithms, neural networks, etc...)
