Abstract : A buoyed sensor array communications system comprises multiple sensor systems electrically connected to a signal transmission line which are positioned at pre-determined locations along the signal transmission line to form a linear sensor array. Each of the sensor systems generates a data signal in response to receiving an address signal. The system further includes; a processor system electrically connected to the signal transmission line for transmitting address signals to enable any one of the sensor systems at a time in a selectively accessed order and has a data storage memory for storing the data signal from each of the sensor systems as stored data. A radio frequency transmitting system is coupled to the data processor and transmits the stored data at a pre-determined time. A negatively buoyant structure connected to the signal transmission line pulls the communications system to the bottom of a body of water upon deployment. A positively buoyant structure supports the processor system and radio frequency transmitting system, and is connected to the signal transmission line. A signal transmission line cutting system mounted in the buoyant structure severs the signal transmission line upon receipt of a cutting system enablement signal generated by said processor system where upon the buoyant structure floats to the surface of said body of water. Then the transmitting system transmits the stored data.
