Atmospheric analysis

This month-long fisheries trawl survey on the RV Tangaroa, aims to estimate the relative abundance of hoki, hake, ling and other middle depth fish species in the Southland and subantarctic areas.

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.

Our team of researchers have recently returned from a voyage onboard RV Tangaroa to retrieve moorings deployed to collect sediment samples from the Kaikōura Canyon.

NIWA forecasters say a marine heatwave is forming around parts of New Zealand after sea surface temperatures (SSTs) warmed considerably last month.

Small orange flecks spotted floating around in a respiration chamber at a NIWA laboratory have led to a discovery about the spawning habits of a deep-sea stony coral in New Zealand waters.

In the North Island, moderate rainfall amounts of generally 25-50 mm occurred across much of Northland and Auckland during the past week, with generally 15-30 mm for much of the western North Island and the western Wellington Region. Conversely, the east coast (including Wairarapa) saw generally light rainfall amounts.

Once a year, technicians from NIWA’s North Island Field Team don helmets and head lamps to check a network of CO2 sensors in the world-renowned Waitomo Caves. The sensors help make sure that heavy breathing visitors aren’t wrecking the caves’ precious natural structures and microclimate.
