kilo-samples per second) to capture strong bandwidth recordings. Cetacean detector algorithm Known as a click detection process, the cetacean detector algorithm was originally implemented in analog electronics to test different dolphins and porpoises in containment and in freedom. The center frequency is 130 kilohertz with a 30 kilohertz bandwidth. The pulse's envelope is tracked through a sequence of short clicks. The lower bandwidths (less than 20 kilohertz) are digitized and the frequencies shifted to be low enough for the human ear. This helps humans understand the acoustic behavior. In between clicks, acoustic behavior can be observed. Behavioral interpolation of the mammals can be inferred between inter-click periods. The system has implemented the SDA14 platform alongside DSP to get full bandwidth waveforms that holds large advantages cetacean examination. Summary ARU's offer large advancements in monitoring underwater acoustics due to strong signal processing and data capturing. The quality of noise is somewhat limited because of the digital and analog systems that are implemented. At the moment this system works best with porpoises, but it is rather versatile and can still be applied to other mammals such as dolphins and whales. Pros and cons Pros In comparison with human observers, ARU's are much more successful at perceiving the species of animals in the area. ARU's permanent record cancels bias as multiple listeners can access the audio and come to a consensus Can also allow for understanding patterns behind the detection of certain animals Can confirm the identification of more rare species Can be used to identify changes in vocalization of species over the years and for what possible reasons Overall good for determining anthropogenic disturbances on species' vocals and distributions over time Installation and removal are done in minutes with less total time needed for people to be on the scene Can track species that have more randomized sounds ARUs can have set times to record through their programming, allowing for a look at specific species Cons Storage can fill up quickly and become a large cluster data that is difficult to decipher and maintain. Reviewing recordings is time consuming A recording failure can lose data. ARUs are expensive and require frequent check ups to replace batteries and maintain microphones. To cover a large area, multiple ARUs are needed as their range is limited. Current and future applications The three main functions of ARU's include monitoring movement, biology, and animal communication in an
