In this issue

  • Beating drought

    How a regional climate history helped save a farm and cure depression
  • Panorama: John Morgan - A quantum leap in New Zealand's science capability

    How long would it take to count all the grains of sand in the world? About 5000 seconds – a little over an hour and 20 minutes – if you had a Cray XC50. NIWA has just installed one at the High Performance Computing Facility in Wellington.
  • Silicon power

    Massive increases in computing power are allowing NIWA scientists to not only analyse more data, faster, but also to envisage completely new experiments.
  • The record summer of 2017/18

    Less than a week before the official end of summer on 28 February, temperatures dropped and a cool breeze made a whistle-stop tour of the country.
  • Water count

    Ruth Beran discovers that public interest in the state of fresh waterways has driven a dramatic change in the tools used by scientists.
  • Drones watch quake aftermath

    NIWA scientists like Leigh Tait were saddened by the human impact of the 2016 Kaikoura earthquake, but he also says that it provided a “massive natural history experiment”.
  • NZ snowline shrinks

    New Zealand’s glaciers have all retreated and lost volume since NIWA started surveying them in 1977.
  • Encouraging interest in science

    Efforts to create interest in STEM education (science, technology, engineering and maths) have led to a 40 per cent increase in tertiary students taking the subjects this year.
  • Q&A - Bloomin' algae!

    A hot and steamy summer saw Kiwis heading down to rivers and lakes to cool off. But they weren’t the only ones enjoying the warmer weather – algae had a great time too.
  • Profile: Bob Newland

    Being prepared to give anything a go and thinking outside the box to get a job done – often in incredibly challenging conditions – is something Bob takes great personal and professional pride in.
  • Solutions: Regional climate change

    As climate change takes hold, regional council planning, sustainability and hazard managers are looking to NIWA for help to understand how their communities will be affected.
  • Citizen science: Monitoring the Maitai

    The first Wednesday of the month finds Philippa Eberlein and her Friends of the Maitai colleagues collecting samples from the Maitai River in Nelson.
