A buoy with the ability to “phone home” has been deployed in Wellington Harbour today to monitor currents, waves and water quality in the harbour.
NIWA researchers have spent part of the last month keeping a close eye on the bottom of Lake Tekapo to find out what it looks like and what is going on below the lake bed.
NIWA’s Fieldays team is basking in the glory of winning the Best Indoor Agribusiness Site awarded by the National Agricultural Fieldays organisation for the 2015 event.
A World Meteorological Organisation panel has confirmed a finding that a temperature of -25.6°C observed at Eweburn, Ranfurly in New Zealand on 17 July 1903 is the coldest temperature recorded for the Southwest Pacific Region.

Our work

Climate Present and Past is a core-funded project under NIWA's National Climate Centre. It aims to explore historical climate data and track past changes in climate through a range of approaches.

ARGO - measuring salinity and temperature across the oceans
Since the early 2000s, NIWA has been part of the international Argo programme. Argo floats takes the pulse of the oceans, collecting and distributing temperature and salinity observations from a global network of more than 3700 underwater robots.
Exploring the deepsea

Despite many centuries of maritime exploration, only a fraction of our planet's seafloor has been observed. NIWA Deepsea Scientist Di Tracey tells us what it feels like to probe deep beneath the waves to see what's living on the ocean floor.

NIWA IrriMet
NIWA has developed new tools that can help farmers decide when to irrigate or fertilise.

This Acoustic Doppler (water) Current Profiler (ADCP) can measure water velocity and discharge in shallow streams, ranging from 15 to 200 cm deep, in minutes.

The H-3600 series is a family of non-contact water level sensors that can connect to an SDI-12 compatible data logger. Eliminates the need for stilling wells and other costly infrastructure.

We can supply an environmentally sealed IP66 rated enclosure suitable for housing Unidata Starloggers to give added protection. It has NIWA-standard external connectors.

This general purpose logger is easy to program using standard Starlog software. It is suitable for standalone or telemetered applications and has an SDI-12 serial data bus.

The NIWA Ecologger provides a cost-effective, telemetry-capable option for many simple environmental data collection needs.

This telemetry-capable data logger is designed for remote operation and used extensively in NIWA's national hydrometric network of water level monitoring stations.

This is the standard precision instrument NIWA uses throughout New Zealand in the National Climate Network, and elsewhere, for rainfall measurement.

This Weather Transmitter is a compact and lightweight multi-sensor instrument that measures the six most essential weather parameters and has no moving parts.

This miniature transmitter measures humidity from 0 to 98% and temperature from -10 to +60 degC. It uses little power, and you can remove its sensor to simplify calibration.

For WMO-standard accuracy and stability we use HMP155 probes to measure Relative Humidity and air temperature in our Electronic Weather Stations.

These gather top-quality data and are used throughout New Zealand in the National Climate Network . Its10m high mast is easily lowered.

We can supply the cables you will need to connect 'instrument building blocks' together to configure a complete system.

A variety of input and output modules are available to use with data loggers. These range from signal conditioning and isolation devices to input expanders and units that enable loggers to control external devices.

We can supply calibrated linear and thermistor temperature sensors suitable for connecting to our range of data collection devices. The calibration information supplied must be entered in the logger scheme.

The Modbus to SDI Protocol Converter (sometimes referred to as ‘BabelStar’) converts Modbus data to/from SDI-12 data. Alternatively it can convert High Speed Serial data to Modbus data.

The EFM300 Electric Fishing Machine provides researchers and environmental managers with a simple and efficient tool for monitoring fish populations in their waterways.

The Current Meter Counter measures the contact closure or electronic switched output from conventional current meters such as Seba, Ott, Oss, Pygmy and Price AA. It is compact accurate and reliable.

To know the true condition of your batteries you need to measure battery capacity. The BMS2000 charges, measures and displays the capacity, in Ampere hours, of up to six 12V batteries at one time.

NIWA uses this data radio extensively throughout the National Hydrometric Network for telemetering water level data.

These RF modems work over long distances, have reliable and secure packet delivery, have seven channels and require little, if any configuration.

A self-contained advanced hydrostatic water level sensor with integrated air compressor. Easy to install and no stilling wells, gas bottles or regulators are needed. Keeps the electronics out of the water.

This smart self-contained air compressor bubbler system enables you to measure water level. Water pressure is coupled through a gas line that can be connected to a pressure-to-electronic-output transducer.

This water surface float-driven encoder converts water level into an electronic serial digital output that works with any SDI-12 data recorder.

This measures and records the Electrical Conductivity (EC) and temperature of water.

The WP Series measures Electrical Conductivity, Total Dissolved Solids, Dissolved Oxygen, Turbidity, Temperature, pH, Redox and Specific Ions.
