1. A system for measuring and acoustically signaling a blood gas saturation of a diver, the system comprising:
- a sensor device, the sensor device comprising a support layer for positioning the sensor device on the diver, the support layer including a light emitter and detector configured to emit and detect light at a wavelength having an absorbance corresponding to a blood gas saturation level of the diver;
a processor coupled to the emitter and detector and configured to control (i) a characteristic of the emitted light, (ii) determine a blood gas saturation level based on an output from the sensor device, and (iii) generate an output signal for an acoustical transmission device that is based on the blood gas saturation level, the output signal being used to acoustically signal the blood gas saturation level to an acoustical receiving device; and
a power source for powering at least one of the processor, the sensor device, and the acoustical transmission device.

Abstract
A system and method for monitoring biometric data of a diver and signaling those data from a first communication device to other communication devices, e.g., those of other divers, on a ship or buoy. A signal generated from a device of the diver can generate a diver identifier, an indication of a stress state of the diver and the diver'"'"'s location.
