Comments.Text: Thank you WMXZ for the questions. My specific question is asking for specific proposed equipment, software, work processes. As for the ethic concerns, if the supported sanctuary is ethical then this equipment would probably be used ethically and the main purpose is to help ensure the health and safety of the residents, so I consider the question and the use of the described equipment to be ethical.

  Here's is how I would do it, as a first draft. Many members of this exchange can do a better job than I, no doubt.
  
  1. For the identification of health and security issue signals:
  
  * 1.1. review literature, ask knowledgeable community members and outsiders;
  * 1.2. collect signals from current residents and select candidate signals; collect additional occurrence data on these signals;
  * 1.3. convert candidate signals in a form usable by the recognition system;
  * 1.4. software to be evaluated: PAMGuard, and/or DC Dolphin Communicator paired with recording software, others TBD
  * 1.5. hardware to be evaluated: low cost laptop or tablet, low-cost hydrophone (high quality recordings are not required)
  
  2. For the real-time signal recognition and notification system:
  
  * 2.1. evaluate DC Dolphin Communicator on tablet with low-cost hydrophone (as used in the identification system in item 1), DC should be able almost as-is to recognize issue signals and notify by email; DC is at <https://play.google.com/store/apps/details?id=sm.app.dc> (disclosure: I wrote it)
  * 2.2. if the option to notify the residents is enabled then we'll need an inexpensive projecting transducer (underwater speaker), and maybe it could be in air, or both in water and air;
  * 2.3. evaluate PAMGuard (on laptop): How hard is it to have it recognize signals? Can it send notification email when an issue signal is recognized? Probably can be modified to do that;
  * 2.4. are there others components to be evaluated?
  
  The equipment part is relatively easy to define.
  
  The hard parts are:
  
  1. The identification of the issue signals.
  2. The encoding of the selected issues signals into a form used by the recognition system, for example, if an artificial neural net (aka. machine learning) is attempted, then a large amount of examples of the issue signals would be required to train the ML and obtain a valid model. A sufficiently large amount of such issue signals may not be available or may be only obtainable over a long period of time which would hinder the benefits of the system. For this reason, a machine learning approach may not be applicable, but this remains to be confirmed.
