A weekly update describing soil moisture across the country to help assess whether severely to extremely dry conditions are occurring or imminent. Regions experiencing these soil moisture deficits are deemed “hotspots”. Persistent hotspot regions have the potential to develop into drought.
A large area of high pressure will take up residence east of New Zealand for the next few days, bringing more unusual springtime warmth to parts of the South Island from tomorrow through to late next week, says NIWA forecaster Seth Carrier.
A weekly update describing soil moisture across the country to help assess whether severely to extremely dry conditions are occurring or imminent. Across the North Island, soil moisture levels have generally not changed significantly during the past week, while across the South Island, soil moisture levels have generally decreased.
An air flow extending from Australia on Thursday and Friday may bring near-record warmth to parts of the interior South Island, says NIWA forecaster Ben Noll. A large area of high pressure to the northwest of New Zealand will help steer this warm air across the Tasman Sea.
A decade of scientific research into how ocean acidification is affecting New Zealand waters has led to far greater understanding of the vulnerability of our marine ecosystems, according to a newly published review.
NIWA scientists have found signs of recovery in the Kaikōura Canyon seabed, 10 months after powerful submarine landslides triggered by the November earthquake wiped out organisms living in and on the seabed.
Sitting at the surface of Taylor Glacier in Antarctica, are layers of ice more than 10,000 years old. And trapped inside those layers are bubbles of ancient air – like tiny time capsules - able to tell scientists a story about what the world used to be like and how humans have changed it.
