Unique Acoustic System Protects Manatees From Injuries And Death

rivers, estuaries, saltwater bays, canals, and coastal areas.
They move from fresh to salt water easily and the Florida
manatee frequents most areas of Florida. It is estimated that
there are approximately 3,000 Florida manatees in existence
today. (Credit: Image courtesy of Florida Atlantic University)
ScienceDaily (Jun. 11, 2008) — Researchers at Harbor Branch
Oceanographic Institute at Florida Atlantic University have
developed and improved upon a unique acoustic system designed to
keep manatees from being injured or killed by flood gates and
boat locks. Locks are used on sections of a canal or river that
may be closed off by gates to control the water level to enable
the raising and lowering of boats passing through. The “Manatee
Acoustic Detection Sensor Protection System” is composed of an
array of unique acoustic transmitters and receivers that provide
non-contact detection
