A Vector deployment in a coral reef is sure to grab the attention of local residents. Completely oblivious of the acoustic intereference it may cause, this Barracuda just "gotta check it out".
File conversion programs
Do you ever need a quick conversion program that takes you from one instrument format to another? Want to see Vector data with Tony Wahl's WinADV, or run wave analyses on Aquadopp data using Quick Wave??
Innovation gets stamp of approval
On April 1st, 2008, The U.S. Patent Office "stamped" the SUV method for wave measurement with the number US 7,352,651 B2, and a formal patent was issued for this technology. The patent represents the culmination of three years of work where the concept of measuring waves from a subsurface buoy was suggested, developed, and tested in the North Atlantic.
New HR release
We are pleased to announce the release of a new HR-Aquadopp firmware and software version. The release includes an option for extended velocity range, for using only a user-specied number of beams and an improved burst mode. The release has full support for 2 MHz units while the 1 MHz version is still in beta.
Tidal energy - real world performance analyses
One of UK’s many renewable energy companies, Tidal Generation Limited, has developed an impeller tidal turbine to produce electrical energy from tidal currents. They contacted Nortek when they wanted to analyze the relationship between incoming currents and produced energy, to understand the effect of waves, and possibly in the future to control the pitch of the turbine blades.
Aquadopp Profiler Installed on WEBB Glider
Nortek has collaborated with scientists to integrate an Aquadopp Profiler on a WEBB Glider.
HR shows the small scales
The pulse coherent technology embedded in the HR version of the Aquadopp profiler provides a higher temporal and spatial resolution than what we are used to seeing with Doppler current profilers. A recent test off a dock in Coconut Grove, Miami illustrates the point.
Sea Technology Magazine Features AWAC
The February 2008 issue of Sea Technology describes a new method for using the AWAC for directional wave measurements from a subsurface buoy.
The world's longest Aquadopp Profilers
What do you do when you have four octagonal pipes deep in the ground, and you want to know the velocity of the water flowing through these pipes? No conventional flow sensor nor any standard Doppler current profiler could solve this challenge, so Alstom decided to talk to Nortek.
Aquadopps are becoming smaller
As part of an engineering effort that lasted for all of 2007, the circuit board inside the Aquadopp and the Aquadopp profiler has shrunk by about 10 cm (4 in). As a result, it is possible to fit the instrument inside smaller spaces and it is easier to integrate the instruments in OEM applications.
Nortek on the move!
The activity level is growing all over the world and Nortek instrument sales made another 25% leap from 2006 to 2007. As a result, both NortekUSA in Annapolis and Dutch subsidiary Qmetrix have been forced to find new offices to meet the demand for more space.
Nortek UK “2008 Student Equipment Grant Awards”
Encouraged by the success of their previous competition, Nortek UK invited post-graduate students working in fields of marine science, to submit research proposals by the end of December 2007, for projects utilising a Nortek instrument. The authors of the two most outstanding proposals were to be awarded their chosen Nortek instrument, for a free 3 month deployment period during 2008. In addition, the best proposal also secured £500 in travel expenses, to attend a national conference in order to present his/her scientific results.
20 DW Aquadopps for Seatronics UK
Nortek deepwater Aquadopp has been selected by one of the world’s leading oceanographic companies. This time Seatronics UK needed 20 deepwater current meters for a deep water pipe route study in the Mediterranean, and careful comparison between the DW Aquadopp and other single point Doppler current meters led to a decision in favor of the Aquadopp.
Buoy in the works...
Pictured here is Nortek's Tom Christian Mortensen, whose extensive field experience has aided in developing a buoy solution that is manageable by shorthanded crews and small workboats. The complete buoy is a 1.1 meters in diameter and approximately 55 kg. Power is provided by 5 solar cells and batteries which is sufficient for winter deployments on the light deprived coast of Norway.
190 kHz "Continental" profiles over 300 meters!
We are pleased to see an increasing number of "Continental" current profilers being put to use in scientific studies and in engineering projects. We are equally pleased that the profiling range of the 190kHz version often exceeds the stated specifications of 200 m.
Nortek delivers first ADCs
Nortek, in cooperation with Ott GmbH of Germany, has completed the development of a new handheld river current meter named "ADC". First delivery took place in November of 2007
