In the channels, the Aquadopps were deployed on a much smoother bottom consisting of sand and coral rubble. The maximum significant wave height recorded was about 2.2 m. The AWAC was deployed in 10 m water depth on the forereef where the bottom was extremely rough (see photo). Read the latest news on Nortek product innovation and exciting features. The instrument array was completed with four Interocean S4 current meters and an Aanderaa tide gauge in the lagoon. Three Nortek Vectors (marked “adv”) were deployed on the reef crest and a Nortek AWAC was deployed offshore to provide directional wave information. Five Nortek Aquadopps (marked “adcp” in the photo) were deployed: three in the major channels between the ocean and the lagoon, one in a blind channel and one offshore of the reef crest. The instrument array is shown in the aerial photo.
The measurement program covered the period from November 26 to Decemwith the aim of measuring the relative contributions of wave, wind and tidally driven flows in the exchange of water between the lagoon and offshore. The photo shows a view along the reef looking south toward Mt Gower (elev. The project was a collaboration between the University of New South Wales Canberra at the Australian Defence Force Academy, the University of Melbourne and New Zealand’s ASR Ltd.Ī lagoon about 1 km wide on the western side of the island is bounded by a coral reef about 6 km long.
