Nortek AS is pleased to announce the release of the new 400 kHz Nortek AWAC, which extends the wave and current profiling capability of this best-selling instrument to 100 m. And for good measure, Nortek has added ice thickness capability.
The 400 kHz retains the same geometric configuration as the earlier 1 MHz and 600 kHz version but gets a different "look" because of the larger transducers. The ice measurements are implemented as a new detection algorithm that is more appropriate to the raw data recorded when the surface is covered with ice.
Please see this report for more details on ice measurements.
