Scientists have discovered an extensive body of freshwater off the Canterbury coast between Timaru and Ashburton.
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.
Across the North Island, rainfall during the past week was generally higher than several previous weeks, with many locations receiving 10-20 mm and isolated pockets of 30 mm or more.
Scientists have recorded more snow on the South Island glaciers this year, but they warn it is simply a temporary break rather than any good news on the climate change front.
Scientists know so little about how storms affect the delicate balance of lake ecosystems that we may be unable to protect them from the effects of climate change, says a NIWA scientist.
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.
Auckland is set to break a climate record on Saturday for the region’s longest dry spell, according to NIWA forecasters.
Across the North Island, the past week once again featured little if any rainfall for most locations. Soil moisture levels in the lower South Island have improved markedly from last week.
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.
Aucklanders should not expect any decent rain for more than 10 days, says NIWA principal scientist and forecaster Chris Brandolino.
Ever wondered what fish is served in a Filet-o-Fish at MacDonald’s? It’s hoki. Fish fingers at the supermarket? Chances are, they’ll be hoki too.
If you want a healthy fishing industry, you need to know how healthy your fish stocks are. Sam Fraser-Baxter talks to a scientist who went to sea to find out.
NIWA has teamed up with Microsoft for a new project using artificial intelligence to combine historic weather records with breakthrough handwriting recognition tools.
Dr Rob Bell worked out a long time ago that sea-level rise is much more than a scientific problem. No wonder then that people say his ability to listen is one of his best traits.
Castle Hill, on State Highway 73 between Darfield and Arthur’s Pass in the Waimakariri Basin, was named for the imposing array of limestone boulders in the area that mirror the look of castle ruins.
Technology and Innovation General Manager, Dr Barry Biggs, looks at the impact of the fast-moving world of “tech” on NIWA’s science.
