Overview
Te Whanganui-a-tara/Wellington Harbour is a nationally significant harbour and port environment valued for the range of ecosystem goods and services it provides. Like other coastal environments surrounded by urban areas, the harbour receives inputs of sediment, nutrients and other contaminants from the surrounding catchments. Such contaminants have the potential to adversely impact on the health and function of its ecosystem.
Greater Wellington Regional Council (GWRC) and the National Institute of Water and Atmospheric Research (NIWA) have been collaborating on the monitoring of Te Whanganui–a-tara since 2016. This collaboration has evolved as a result of a need by GWRC to have water quality data from Te Whanganui–a-tara in order to assess changes or impacts from the surrounding catchments. The use of real time telemetered water quality buoys coupled with discrete water quality sampling aims to build a baseline picture of water quality in Te Whanganui–a-tara.
Results
Results summarises data collected by WRIBO, Kelburn weather station, and Hutt river Taita gorge flow gauge from July 2017 to May 2019 for the variables below. Previous data summaries are available on request.
- Wind direction & speed
- Water currents (direction & speed)
- Air temperature
