Pilot aquaculture farm

Farm consists of five cascaded layers of production tanks. Water flows by gravity through each layer so that the effluent from one layer becomes the feed stock for the next. The farm is designed to study trophic interactions between the layers and the use of marketable organisms as a bio-filter in land based aquaculture. Ocean water is pumped and filtered to 200 µm before making a single pass through the farm. Total water volume of the farm is 65 m3 . Tank Oxygen levels can be monitored and controlled, and flow rates and temperatures are continuously monitored.

Total Volume 66 m3

Sea water flow rate: 14m hr-1


Wave logger and current profiler (ADCP with acoustic surface tracking)
Nortek AS
600kHz AWAC

Measures and logs surface waves and ocean current profiles as a function of depth using acoustic Doppler sonar. With connected software produces directional wave spectra and statistics as well as current profiles as frequently as each 30 minutes.

Max depth 60m; profile minimum cell size 0.5m;
Sampling rate 2 Hz (waves), 1Hz (current)
Waves: Hs to 15m, accuracy 1% or 1cm
Current: +/- 10ms-1range; +/- 1cms-1 uncertainty

Submersible data acquisition & logger system
RBR global
RBRmaestro custom configuration

Measure, log and (with appropriate cabling) transmit (RS485) 10-channels of analog data, sampled at up to 6 Hz.

2 channels are reserved for temperature and pressure (depth); all others are 0-5V (14bit). Maximum depth (exclusive of attached sensors) 2000m. Can store up to 30M data points, up to 3 month autonomous battery life (internal batteries, life depends on sensors & sampling regime).
