NORBIT Aptomar acquires the SeaDarQ radar system for environmental monitoring
Nortek announces the sale of its SeaDarQ radar technology for environmental monitoring and oil spill detection to NORBIT Aptomar, a technology provider to global maritime markets.
Why patches are the best anti-biofouling solution for an ADCP
We all want our ADCP to gather data accurately and work for as long as possible, but biofouling can stop us achieving both of these objectives. When marine organisms accumulate on a transducer surface, the instrument’s performance can be greatly diminished.
New 250 kHz version of Signature VM Coastal offers accurate current profiling to 200 meters
Nortek has launched the Signature VM Coastal in a 250 kHz version. This completes the company’s suite of vessel-mounted acoustic Doppler current profilers (ADCPs) designed to measure coastal movements throughout the epipelagic zone.
Nortek redefines current profiling from autonomous vehicles
Installation and operation of current profiling instruments on remote unmanned or autonomous surface vehicles (USVs and ASVs) can be fraught with difficulties. Nortek has made it a lot simpler – and more useful – by combining its Signature VM acoustic Doppler current profiler (ADCP) system with specially customized software.
How to get discharge data from Nortek’s vessel-mounted systems
Discharge, or volumetric flow rate, is a key factor in the assessment of watersheds, estuaries and coastal oceans. To date, obtaining discharge with Signature VM data has been left to the user, but the required computation sequence can be a challenge. The latest version of the Signature Review software makes the process easier for users.
Current measurement made simple and easy
Measurements of current profiles do not have to be complicated. Here’s why ADCPs in the Aquadopp Profiler series prove that current profiles can be easily obtained by users who are less experienced:
U. Washington/APL use Nortek’s Signature1000 to observe fine-scale oceanic velocity structures
The 5th, vertical beam in the Signature1000 can provide unprecedented resolution when using pulse-coherent mode (HR)
A tailor-made buoy makes the deployment of Signature ADCPs even easier!
We have made life even easier for those working with ADCPs in the field: Nortek is now launching a custom-made subsurface buoy ideal for use with the Signature250 and Signature500 ADCPs.
Simplifying vessel-mounted current profiling and biomass measurements
By incorporating a current profiler and echosounder in one easy-to-install, vessel-mounted instrument, Nortek is making life more straightforward for researchers interested in current profiling and biomass measurements in the upper ocean boundary layer.
Change of management as Nortek grows and develops
After over two decades at the helm of Nortek, a specialist in oceanographic instrumentation, Atle Lohrmann is taking on new challenges at newly started Hefring Engineering in Boston. Nortek’s new CEO, Finn Ivar Marum, has been entrusted with the task of ensuring Nortek’s continued growth.
Helping young sailing athletes learn and compete internationally
Sailors are as passionate about the ocean as we are. Nortek has long sponsored young sailing athletes to enable them to learn and to compete internationally. Currently, we are helping the athletes in the Nortek Sailing Team to compete on an international level and develop their capabilities.
Two problems in sediment measurements tackled
ADCPs are great for current measurements, but can they be improved for sediment measurements? Absolutely! In this article you will find out how the Signature1000 echosounder improves two important aspects of your sediment measurements.
