Hydroid's Most Compact AUV Ever Produced

When scientists and engineers at Hydroid set themselves the task of designing one of the most compact autonomous underwater vehicles (AUVs) ever produced, they collaborated with Nortek to provide high-quality navigational equipment capable of fitting such a small form factor.   Hydroid has built on REMUS AUV technology – first developed at the Woods Hole Oceanographic Institution in Massachusetts – to become a leading manufacturer of trusted, field-proven lightweight AUVs for underwater search and survey. Acquired by Norwegian technology firm Kongsberg Maritime in 2008, the

Sensors Switched-out at the Bourne Tidal Test Site

Two Nortek Signature 500 acoustic doppler current profilers (ADCP) at the Bourne Tidal Test Site have been removed and replaced with new, freshly charged Signature 1000 systems.The data that is being collected is part of the research being conducted by Soroush Kouhi a PhD candidate at the University of Rhode Island (URI). He and his team of students are working out the details of how best to measure and characterize the water flow resource at tidal turbine sites. The Bourne Tidal Test Site is a great place to learn about how to deploy, calibrate and manage these sensors in the turbulent waters of the

are coming to fruition as fisheries management is begins to take on a more holistic ecosystem approach and funding becomes even more limited. In order to match these changing needs, scientific instrumentation must follow suit.The Signature100 long-range current profiler from Norwegian manufacturer Nortek lends itself well to collaborations between physical and biological scientists, since it uniquely combines the capabilities of an ADCP and a biological echosounder in one. It is currently the only instrument in the world providing this combined capacity, Nortek said.“The biggest advantage of

Optimizing the Tides

U.K. alone, the government estimates that wave and tidal combined has the potential to deliver 30 – 50GW equating to around 20 percent of the country’s current electricity needs. As investment and innovation begin to surge across the sector, Dutch-based tidal energy leader Tocardo joins with Nortek to help optimize the operational performance of its turbines.  Sicco Kamminga, Director of Nortek’s Netherlands division, explains how ADCPs are contributing to solving the world’s sustainable energy needs. Unlike other forms of renewable energy, tidal energy isn’t dependent

The exclusive mooring design includes a data swivel to ensure that the subsea instruments can continually report data without the risk of cable entanglements in the dynamic environment.   The buoys have a substantial power consumption rate owing
