HydroCal is Ocean Networks Canada's hydrophone calibration system. It generally consists of a hardware jig to position and hold the hydrophone under test along with reference sensors and sources, a data acquisition system and software to run the data acquisition, do the analysis and produce a calibration certificate. The goal is to robustly calibrate a hydrophone to facilitate observing in the ocean. Sound is the key mechanism for communication and interaction in the ocean. HydroCal can calibrate almost any hydrophone: analog or digital, low frequency (via a bench top rig) and high frequency (in-situ, live or offline).
