PAMGUARD

The PAMGuard software provides a suite of Detection, Classification, and Localization algorithms developed specifically for the many types of sounds made by different species. The algorithms are backed up by a powerful user interface that allows a human operator to view sounds in real time, confirm the output of the automatic detectors, and mark out sounds manually when automatic detection is not possible... Marine mammals, whales and dolphins in particular, are highly vocal. This means that it's often easier to hear them, than it is to see them. This is particularly true at night or in poor weather.
