Collaboration with NIWA to develop salinity models

The Resilient Shorelines team would like to thank the Brian Mason Scientific & Technical Trust and also NIWA for bringing their support to this exciting research.

An interesting though unexpected finding of this work was the discovery of a leak in the Woolston Tidal Barrage. The model calibration was excellent in the lower estuary and in the Avon / Ōtākaro. However there was a strong  anomaly between the modelled versus observed salinity datasets for the Heathcote / Ōpāwaho that have been influenced by the tidal barrage leakage. Read more about it here in the Brian Mason Trust report on 'Development of a fine-scale salinity model for the Avon Heathcote Estuary Ihutai'.

Earthquakes cause a shift in the location of īnanga spawning sites

One of the main objectives for our whitebait conservation study was to determine if the earthquakes had altered the location of spawning sites for īnanga (Galaxias maculatus) for spawning. They are typically found in specific locations near the freshwater-saltwater interface at rivermouths. As such, īnanga spawning sites are potentially a very good indicator of change. Conversely, they may be especially vulnerable to changes that affect the availability or condition of suitable habitat.

And the answer is - yes, there has been a major shift in the location of spawning compared to all previous records!
