1. AWAC in concert with fish

This photograph shows a prototype AWAC installed in TaiChung harbor. The system is installed at a depth of 15 m on top of a 2-ton concrete frame. During the first year of deployment the peak significant wave height in the area was about 7 m while the peak currents exceeded 1.5 m/s.

5. World championship in NDPs

AndreDolle5 The ship is on its way to deploy 4 NDPs outside Boulougne, France as a part of a project for French Oil company Elf to establish an oil terminal in the area. An Aquadopp deployed for test purposes can bee seen on one of the NDP frames.

BartSpelt66. Where is the Aquadopp?

This Aquadopp was used in the project "Case Study Petten" where it was deployed for one year in 2 m of water about 400 m off the Dutch coast. The Aquadopp was mounted on a pole, facing downward and the data were transmitted over a radio link. As strange as it may seem, the Aquadopp continued to provide reliable data even in the overgrown state displayed in the first picture.

Can you see where the Aquadopp is?
