A few examples of work that Northland Freshwater Data has done in the past.

Telemetered water quality buoys built by Scottie

Our own buoy platform available to clients

Structure built for safe access to DO/Temp data logger at most flow conditions, Ruakaka.

Maintenance on NRCs Nine pin buoy, Bay of Islands

Bio fouling on a Phantom T30 Turbidity sensor

Another structure built to access a Hobo U-26 data logger in Doubtless Bay

Rigging for two MiniDot DO/Temp loggers used in Lake Omapere.

Suction dredge head used in Caulerpa invasive seaweed control, Bay of Islands.

Site built to measure ecosystem services provided by wetlands as part of PhD research.

Programmable auto samplers can save many site visits, Baylys Beach

Hobo U-26 DO/Temp data logger rigged with a Hobo U-20 pressure data logger to give water depth

Sediment laden water from large land slip discharges into the Kaikou River, suspended sediment can be monitored continuously using turbidity as a proxy.

Internal components of a water quality buoy built by Scottie

A range of battery powered non telemetered, from the right DO/Temp, 2 x pressure, temp/ conductivity.

Validating MiniDot DO/ Temp loggers using a recently calibrated hand held meter, quality systems are of the utmost importance.
