ISIIS Technology / Towed Vehicles

We offer ISIIS instruments for purchase and for rentals.

ISIIS Prototype Video
ISIIS Prototype

In 2007, an initial prototype was delivered to the University of Miami. This robust platform has allowed testing and refining ISIIS optical technology. It has also been used for demonstration purposes.
This vehicle had a depth rating of 50+ meters. Data is transferred via fiber optic to the ship and the vehicle water position is function of the length of tether deployed. This particular vehicle platform is discontinued.

ISIIS-2

This vehicle is the newest and most advanced design. The first model is being delivered and ocean deployments are scheduled in the spring of 2009.
With a depth rating of 200m, the vehicle is capable of pre-programmed undulation and can be towed off the side of the ship to avoid the disturbances created by the tether. Particular attention has been given to provide for undisturbed flow path in front of the imaging viewports. This vehicles is equipped with environmental sensors (CTD, PAR, Fluorometer) and a navigation ADCP. Plankton images are transferred via fiber-optic to the ship. This vehicle can also be delivered as a basic non-undulating platform, and fitted with your own environmental sensors.

ISIIS-GigE

This vehicle is in development and will provide a lower cost alternative to ISIIS-2.
ISIIS-GigE is a non undulating platform. Its position in the water column is function of the length of tether deployed.
The vehicle stores data onboard and only requires the use of a standard oceanographic CTD winch.
As for ISIIS-2, particular attention has been given to provide undisturbed flow path in front of the imaging viewports. This vehicles is equipped with a CTD and a navigation ADCP.
