Lightweight Buoys
OSIL200 data buoys are available in 4 different sizes, ranging from a diameter of 1.2 m with a buoyancy of 200 kg up to 3 m in diameter with 9,000 kg of buoyancy. They are manufactured using rotationally molded polyethylene hulls around a galvanized steel or welded polyethylene central structure and have a customized 316 stainless steel frame attached to the top for mounting instrumentation. OSIL.

GPS Receiver
The standard C-Nav 1010 system comprises a high-sensitivity single-frequency GPS receiver integrated with an L-Band demodulator operating on a single antenna. The custom-built demodulator receives GPS corrections, quality control and integrity data from a constellation of 6 high-power Inmarsat communication satellites. This constellation provides 200 percent coverage from latitudes 72° N to 72° S. C & C Technologies Inc.

Submersible UV Nitrate Sensor
SUNA provides real-time, chemical-free nitrate calculations in coastal and freshwater environments using advanced UV absorption technology. The sensor is complemented by a newly developed Windows-based software package for set-up, integration and in-field calibrations. SUNA has been redesigned for lower cost and easy integration into existing water monitoring systems. Satlantic Inc.

Side Scan Sonar System
4700-DFX is a dual-frequency 300/600 kHz system that combines multipulse technology for high tow-speed capability with dynamically focused transducers, which provide high-resolution imagery at increased range—as much as 20 to 30 percent more than conventional technology side scan systems. EdgeTech Marine.

Nautical Charts
Chart Navigator Pro is a convenient and cost-effective way to have charts for the entire U.S. coastline, plus an easy-to-use method that keeps charts current with free updates. Chart Navigator Pro includes NOAA charts—raster and vector—and Contour 3D charts with GPS planning and cruising software as well as a built-in guidebook gazetteer with Internet weather overlays on the charts. It comes on 13 DVDs. Maptech Inc.

Chart Capturing Tool
ENC digitizing software is now available as freeware. It is currently in use by more than 40 hydrographic offices. It can quickly generate ENCs from survey sheets and paper charts. Users of the freeware license will be offered professional assistance under a support agreement that can be renewed annually. The designer software can be downloaded from www.enctools.com. Seven Cs.

Arctic Sailing Life Raft
Arctic life raft comes in a specially heated container that ensures that the life raft can be deployed at temperatures as low as -45° C. A special heating system in the container prevents the container itself from over-icing and stops the life raft linings from freezing together. One supply box can heat 2 life raft containers and the container is simply plugged into the supply box. VIKING Life-Saving Equipment.

Wireless Data Logger
Wireless WizardT is now available to scientific researchers monitoring experimental temperature and/or humidity in a 30-day trial offer. Data loggers can be monitored in real time from a desktop PC or other computer workstation and eliminate the delays associated with data downloading and cabling of other temperature and humidity data logger technology, the company said. Dickson Co.

Multiparameter Instrument
Seaguard Platform is a self-recording instrument with storage on a small SD card. The instrument is delivered complete with pressure case. Sensor calibration coefficients are automatically downloaded. Aanderaa Data Instruments.

Fiber Optic Cable
Improvements in design and manufacturing of the LANmark-1000 cable have resulted in a best-in-class Category 6 Unshielded Twisted Pair, the company said. Through this redesign, the LANmark-1000 has increased all crosstalk parameters by 4 dB over the old design, said the company. Berk-Tek, a Nexans company.

Diver Interdiction System
DIS incorporates a 20 cu. in. air gun that is deployable pier side from a small boat. It allows continuous variable firing pressure over the firing pressure range of the gun. Hydroacoustics Inc.

Diesel Power Unit
The Power Unit features a hydraulic or air starting system, powder-coated aluminum or stainless steel enclosure and optional center point lifting eye. It also includes an insulated exhaust system wrap and single or double side doors. Ideal for the tank barge industry, it supplies 173 hp at 2,200 rpm. Laborde Products.

Personnel Management Solution
