Dear colleagues I am currently surveying information on devices to monitor ambient noise in near shore areas for extended periods of time. The devices should be self-contained data loggers and should be able to record underwater sound with a reasonable bandwidth (at least up to 22 kHz; better higher than that). They should be reasonably handy to be deployed near an existing buoy or on the seafloor (provided there is a kind of a pop up mechanism). A predefined sampling regime for the recordings should be incorporated. Please respond directly to me; I will collect the replies and post them as a summary for anyone else interested.
