Dear list members Peter Dobbins, Ultra Electronics and I, Irene Voellmy, University of Bristol, are currently conducting a survey to evaluate current and future requirements for Passive Acoustic Monitoring (PAM) devices for research (e.g. aquatic animals, acoustic environments), conservation and anthropogenic noise emission monitoring purposes. This survey is conducted as part of an ongoing study investigating the current state of the art in PAM systems. In this survey, we particularly investigate whether and where users of PAM systems locate gaps in available devices and how further developments of the techniques could meet these requirements. If you are a user of PAM systems, we would be grateful if you could take part in this survey and complete the questionnaire on: http://www.surveymonkey.com/s/J355HDV The deadline for completed questionnaires is *30 September 2013*. The survey should not take more than 15 minutes and your information will only be used for statistical purposes. Your name and contact details will not be linked to your answers and will not be conveyed to third parties. Thank you very much for your help and your time, Irene Voellmy and Peter Dobbins -- Irene Voellmy School of Biological Sciences University of Bristol Woodland Road Bristol BS8 1UG Irene.Vollmy@bristol.ac.uk Phone: +44 (0)117 95 45945
