A turtle alerting system and method utilizes an acoustic signal that may be provided in a first, low frequency range, a second, mid-frequency range, or a third, high frequency range. One or more of those acoustic signals may be accompanied and/or modulated by either an ultrasonic signal or a MHz signal, so as to provide a carrier for the acoustic signal. Further, a beam of light may be used as another type of alerting sensor. Lastly, a sonar may be used to steer the system in a direction in which turtles may be located.
