Dear colleagues:
I would very much appreciate your help in building a collection of marine
mammal vocalisations.
My name is Peter Holden and I work for the Marine Conservation Society
Seychelles (MCSS). We are currently undertaking a project on marine mammals and
a major part of the research is based on acoustic detection and recognition of
marine mammals. To aid in species detection during PAM surveys and hundreds of
hours of acoustic data collected via autonomous recorders, I am currently in
the process of building a classifier/recogniser to help in the identification
of species in real time (PAMGuard) during surveys and also for post analysis of
the audio files (Song Scope).
To achieve this I require a number of varied vocalisations (i.e. tonal and
impulsive sounds) from species found in the area (see species of interest list
below) for training data, it would be beneficial if the recordings are in .wav
format and varied in amplitude of the perceived signals. It would be even
better if these recordings were made in the South West Indian Ocean :D
Species of interest:
Southern Right Whale (Eubalaena australis)
Blue Whale (Balaenoptera musculus)
Fin Whale (Balaenoptera physalus)
Sei Whale (Balaenoptera borealis)
Bryde's Whale (Balaenoptera brydei)
Common Minke Whale (Balaenoptera acutorostrata)
Humpback Whale (Megaptera novaeangliae)
Sperm Whale (Physeter macrocephalus)
Pygmy Sperm Whale (Kogia breviceps)
Dwarf Sperm Whale (Kogia sima)
Cuvier's Beaked Whale (Ziphius cavirostris)
Blainville's Beaked Whale (Mesoplodon densirostris)
Longman's Beaked Whale (lndopacetus pacificus)
Killer Whale (Orcinus orca)
Short-finned Pilot Whale (Globicephala macrorhynchus)
False Killer Whale (Pseudorca crassidens)
Pygmy Killer Whale (Feresa attenuata)
Melon-headed Whale (Peponocephala electra)
Rough-toothed Dolphin (Steno bredanensis)
Risso's Dolphin (Grampus griseus)
Common Bottlenose Dolphin (Tursiops truncatus)
Indo-Pacific Bottlenose Dolphin (Tursiops aduncus)
Pantropical Spotted Dolphin (Stenella attenuata)
Spinner Dolphin (Stenella longirostris)
Striped Dolphin (Stenella coeruleoalba)
Fraser's Dolphin (Lagenodelphis hosei)
If anyone could supply any of the species on this list that would be amazing!
In return for your donation of audio files I would be more than happy to
discuss and help with development of your own classifiers/recognisers and send
the classifiers relating to the species you have supplied.
Thank you for your help,
Kind Regards,
Peter Holden
Marine Mammal Acoustic Researcher and Project leader,
