A weekly update describing soil moisture patterns across the country to show where dry to extremely dry conditions are occurring or imminent. Regions experiencing significant soil moisture deficits are deemed “hotspots”. Persistent hotspot regions have the potential to develop into drought. This will be the final update of the Hotspot Watch for this season. Weekly Hotspot Watch updates will resume in the spring.
New Zealand has just over 50 native freshwater fish species. Of these, 85 % are endemic and 75 % are deemed to be at risk of decline or are threatened.

High-resolution mapping has produced the first ever global estimates of coastal habitat damage caused by anchoring.
Greater Wellington Regional Council regularly assess sediment quality and seafloor community health in the subtidal areas of Te Awarua-o-Porirua (Porirua Harbour) and Te Whanganui-a-Tara (Wellington Harbour).
NIWA is contributing to an international effort to help developing countries reduce the impact of biofouling on aquatic-based industries and environments.

The annual end-of-summer snowline survey of more than 50 South Island glaciers has revealed continued loss of snow and ice. Last week, scientists from NIWA, Victoria University of Wellington, and Department of Conservation took thousands of aerial photographs of glaciers. Some of them are used to build 3D models that track ice volume changes.
This week’s torrential rains have set a new national rainfall record.
