Deployment off Coconut Island in Kaneohe Bay, Hawaii
A one month long moored field test was conducted in Kaneohe Bay from October 3, 2016
to November 2, 2016. The deployment site was located at 21.43° N x 157.79° W, on a floating
dock anchored off Coconut Island (HIMB) in a depth of approximately 16 meters (Figure 18).
Kaneohe Bay, located on the eastern side of Oahu, Hawaii, is a complex estuarine system with a
large barrier coral reef, numerous patch reefs, fringing reefs, and several riverine inputs. Tides in
Kaneohe Bay are semi-diurnal with mean tidal amplitude of approximately 68 cm day.

Time series results of ambient conditions for tidal height, temperature, and salinity are
given in figure 19. Temperature at the sensor level ranged from 24.5 to 27.9 °C and salinity from
27.3 to 34.8 PSU over the duration of the field test
The Real-NO3 was not deployed at HIMB at the manufacturer’s decision.
