Undersea Beacon Deployment

This underwater deployment system holds several transponders entirely by vacuum force which can be individually released to mark a location. Each transponder is configured in weight and dimensions to compensate for any ballast changes which occur in the AUV during deployment

Smart Tag

Smart Tag is a miniature, long-endurance acoustic tag to be used for tracking a wide variety of marine animals from finfish to whales. The tag has Autonomous Underwater Vehicle (AUV) tracking and imaging capability – better suited to unassisted animal tracking than current satellite methods, enabling two-way communication & increased range.

PHORCYS Marine Biological Oxygen Demand Sensor

A semi-autonomous submersible sensor system that passively samples the water column in situ. The sensor performs real time, direct oxygen consumption measurements for quick turn-around.

Passive Ballast

The Passive Ballast and Semi-Passive Ballast systems take advantage of ambient water pressure to achieve both positive buoyancy while on the surface and neutral buoyancy while submerged, all while requiring no or very little power.

On-Call Buoy

The On-Call Buoy was developed as a “whale-safe” fishing method, an alternative to closing areas, securing vertical lines on the seafloor until released on command. The On-Call Buoy holds the vertical end line on a spool anchored to the seafloor, thereby reducing the risk of entangling whales in the rope.

Dynamic Electric Motor

The Dynamic Electric Motor offers a more efficient power source coupled with noise and weight reduction. The design allows for low voltage operation and eliminates the need for a transmission.

Contaminant Fingerprinting

This technology advances contaminant monitoring by using multidimensional gas chromatography (GC x GC) with mass spectroscopy coupled with a software package to provide a high-resolution contaminant fingerprint analysis of complex mixtures of synthetic organic chemicals, natural products, and/or petroleum hydrocarbons.

Compact Dissolved Methane and Gas Sensor

The Dissolved Gas Sensor supports field-portable, in-situ, and bench-top measurements. The sensor can measure dissolved gases in liquids using only milliliters of the sample and produce a sample analysis time of only minutes. In addition, using a hollow-core fiber optic sensor allows analysis to be simple, robust, and conducted with a compact configuration.
