Across the North Island, rainfall during the past week was quite variable. Moderate rainfall occurred in the West Coast and Southland. However, rainfall was generally meagre from Marlborough to southern Canterbury.
Scientists undertaking the annual Southern Alps end-of-summer snowline survey this week will be using advanced photographic technology to help clarify obscure snowlines due to ash and dust from the Australian bushfires.
Across the North Island, slight soil moisture increases were observed during the past week as a front brought much needed rain to drought affected areas. However, soil moisture levels continue to be well below normal across the vast majority of the island. Across the South Island, soil moisture levels generally increased in the north and decreased in the south during the past week.
NIWA researchers have helped unlock information trapped in ancient air samples from Greenland and Antarctica that shows the amount of methane humans are emitting into the atmosphere from fossil fuels has been vastly underestimated.
Nearly all of the North Island has reached official hotspot status, with only a few isolated areas that have not quite reached hotspot criteria. Current hotspots in the South Island now include Nelson and nearby parts of Tasman, much of Marlborough, along with northern Canterbury, Banks Peninsula, and parts of Ashburton and Selwyn districts.
A giant squid and several glow-in-the-dark sharks were surprise finds for NIWA scientists last month on the Chatham Rise during a voyage to survey hoki, New Zealand’s most valuable commercial fish species.
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.
