Scientists across NIWA use specialist tools manufactured across the world to perform their research and environmental consultancy. Here are some of the advanced instruments that help keep NIWA on top in its field.
NIWA's Lauder facility has two Bruker FTIR spectrometers. These instruments remotely measure trace gases in the atmosphere. Lauder is also responsible for the operation of a third Bruker FTIR at Arrival Heights, Antarctica.
Ocean water properties such as temperature are measured directly, while conductivity is used to tell us the salinity. It also captures water samples at different depths for a variety of chemical and biological measurements made either on the vessel or back in the laboratory.
NIWA operates two mobile air quality monitoring trailers containing equipment capable of measuring a range of key air contaminants and meteorological parameters to enable quick and easy investigations of local air quality issues across New Zealand.
Modern marine geoscience requires accurate and detailed subsurface information for the mapping of geologic structures and sedimentary sequences beneath the continental margin. In order to acquire this information NIWA purchased a Multi Channel Seismic system (MCS) in December 1996, consisting of a 24 channel streamer, seismic source and acquisition hardware.
Hull-mounted on the RV Tangaroa, the EM302 multibeam echosounder maps the seafloor using a fan of 288 acoustic beams, producing up to 864 soundings per ping in dual swath mode, providing 100% coverage of the seabed.
NIWA uses Trimble RTK GPS surveying equipment to undertake precise topographic and bathymetric surveys. These surveys are used to measure beach stability, river bed erosion and deposition, and to make digital terrain models of rivers for 2-dimensional hydrodynamic modelling.
