A new international study using ancient swamp kauri from Northland shows a temporary breakdown of Earth’s magnetic field 42,000 years ago sparked major climate shifts leading to global environmental change and mass extinctions.
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.
People along the Kapiti and Wanganui coast may spot NIWA’s research vessel Kaharoa operating close to shore in the next few weeks as scientists carry out a survey of snapper, tarakihi, red gurnard and John Dory.
NIWA’s South Island snow and ice monitoring stations have confirmed what many skiers have been talking about: winter has been dry and snow coverage has been poor. In fact, several sites have recorded half their typical snow depth for this time of year.
After a decade-long effort, NIWA’s latest Biodiversity Memoir has just rolled off the presses. Written by marine biologist Kareen Schnabel, the 350-page treatise presents everything we currently know about the different kinds of squat lobster living in New Zealand’s waters.
