Data plot of the bottom-track capacity of an advanced DVL from Nortek.

DVLs with bottom-tracking algorithms that improve accuracy and reliability for subsea navigation

Navigating subsea presents many challenges, and having a reliable navigation system is critical for successfully conducting a subsea mission with an ROV or AUV. Why is a sophisticated DVL with an advanced bottom-tracking algorithm crucial f...

NORBIT Aptomar acquires the SeaDarQ radar system

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

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 gr...

250 kHz version of Signature VM Coastal offers accurate current profiling to 200 meters

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

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 ...

Nortek is one of many suppliers of state-of the-art maritime equipment whose output needs to be interpreted by the crew on a ship’s bridge.

Nortek contributes to digital innovation on the ship’s bridge

Nortek is one of many suppliers of state-of the-art maritime equipment whose output needs to be interpreted by the crew on a ship’s bridge. At present, that means analyzing readings from multiple interfaces – a process that can lead to erro...

Site of Hagenstein deployment with discharge tracks shown with white line. The ADM discharge station is located at the downstream weir.

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...

Aquadopp Profiler series is a good option for users who are less experienced

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:
