Broadband Subsea Acoustic Recorders

Applied Ocean is currently offering the Poseidon series broadband underwater acoustic recorders for shallow and deepwater deployments. Recording underwater noise has never been easier.

These instruments are field proven and are fully automated with an easy to use graphical user interface for configuring to suit your mission needs. The operator has the choices of sampling durations, and preset delays allowing for several configurations to suit longer run times or more frequent sampling. Connection to the instrument with a laptop or PC is simple using a provided network cable, and recharging is just as easy.

The Poisedon series acoustic recorders can be customized in both hardware and software to meet your particular application requirements. For easier useage, we offer a deployment frame that can be operated using a winch, or ROV (remotely operated vehicle) platform. Poseidon background recorders are designed for capturing acoustical energy, but can be customized for use with several other technologies such as RF and optical hardware.
