The first Targeted Riparian Management Course since 2015 was held for Hawke’s Bay Regional Council staff in Napier over two days in late February 2022.There were 12 Hawke’s Bay Regional Council staff on the course with a background in physical geography, looking to increase their knowledge around stream ecosystems.
NIWA’s Snow and Ice Network (SIN) provides information on snowfall, depth of snowpack, snow melt and climate for ten alpine sites across New Zealand, including Mueller Hut above Mount Cook Village.
The snapper contained a tag – known as a passive integrated transponder (PIT) – that was implanted into the fish on 21 February 2002 by NIWA principal technician Derrick Parkinson, who incidentally still works at NIWA.
A team of scientists from New Zealand’s National Institute of Water and Atmospheric Research, or NIWA, recently observed something different.The slopes of the underwater volcano are still largely as they were before the eruption; the same features still contour the surrounding seafloor.
NIWA’s research vessel, RV Tangaroa , has returned from a month-long expedition as part of the Nippon Foundation-funded Tonga Eruption Seabed Mapping Project (TESMaP), where scientists were studying the effects of January’s eruption of Hunga Tonga–Hunga Ha'apai (HT – HH).
NIWA’s Freshwater Species Programme Leader Dr Paul Franklin said World Fish Migration Day, on May 21, is a good time to remind New Zealanders of the challenges migratory fish face, and also the research that is underway to provide solutions.
GloFouling Project Technical Analyst John Alonso, based in London, said the guide developed in partnership with NIWA will help each country deliver an economic analysis to understand the potential benefits of a policy to prevent or manage invasive aquatic species introduced by biofouling.
In a rare opportunity to improve understanding of the nature and impact of a major volcanic eruption, NIWA scientists are sailing to Tonga to survey the ocean around the Hunga-Tonga Hunga-Ha'apai (HT–HH) volcano and surrounding regions.
Dr Lauren Vargo from Victoria University of Wellington says the retreat that we're seeing is due to the majority of New Zealand’s glaciers losing mass most years over the past decade.
NIWA meteorologists say the 103 mm of rain from 4am-5am recorded at Maungatapere near Whangārei on Monday 21 March is a new national hourly rainfall record for a low elevation station.
NIWA scientists and Toitū Te Whenua Land Information New Zealand (LINZ) have used satellite technology to chart the Cook Islands’ seafloor in never-before-seen detail.The work was done as part of Seabed 2030 - a collaborative project to produce a definitive map of the world ocean floor by 2030.
“Hoki are one of the species we research – they have major spawning events, but we are currently only able to collect data on these for a few weeks every two years.NIWA hopes to be routinely using the vessel for monitoring fish within the next five years.
NIWA is asking people in flood-affected areas to contribute photos to a national database to support understanding of flood hazard and flood risk.I am really excited by the development of NIWA’s citizen science app, as we look to gather more information to support our country’s flood management decision-making.”.
Marine scientists from NIWA have been on the hunt for high-risk invasive species as part of their latest biosecurity survey, designed to detect marine animals and plants that come in from overseas.
During the 2021 America’s Cup, NIWA’s supercomputer, the largest in New Zealand, was used to analyse past environmental conditions (hindcasting), predicting future weather (forecasting) and modelling ocean currents in the Hauraki Gulf – all to an extremely high resolution.
Thirty years of management informed by a raft of scientific research appears to now be paying dividends.In the Hauraki Gulf, commercial and recreational fishers are reporting improving catches, and NIWA scientists will soon be able to estimate whether the highly valued Hauraki Gulf snapper population is seeing a similar increase.
While both the astronomical and meteorological definitions are valid, NIWA forecasters have turned to Mother Nature’s weather patterns, looking at the warmest 90-day period of the year to provide another perspective on when summer in Aotearoa New Zealand begins.
As we all move to the NZ COVID-19 protection framework, and in accordance with our health and safety risk assessment and in consultation with our staff, NIWA is proposing to introduce a Vaccinated Workplace Policy from 15 December 2021.
Dr David Thompson, a seabird ecologist at NIWA, highlights the hurdles these little birds must go through to successfully raise young: “Breeding for kororā can be a stressful time because they need to find food for both themselves and their chicks, with one adult remaining at the nest while the other hunts.
One of the best ways to reduce the likelihood of Covid-19 being transmitted in Aotearoa New Zealand classrooms is simply by opening doors and windows to create natural ventilation, say NIWA air quality experts.
Science takes NIWA employees to some stunning locations and leads to some special encounters, and every year the research organisation holds a photographic competition for staff working across its climate, oceans and freshwater platforms.
New NIWA-led research shows increasing flood risk is going to be what leads people to make changes to adapt to sea-level rise.“Rising seas are slowly causing a trifecta of impacts along coastlines in Aotearoa: increasingly frequent flooding, coastal erosion and even permanent inundation,” says Dr Scott Stephens, NIWA Chief Scientist for Coasts & Estuaries.
After 40 years of work, retired NIWA fisheries scientist Larry Paul has just published a 793-page bibliography of references to New Zealand marine fishes.For all that the bibliography covers, Larry says new species of fish are still being discovered throughout New Zealand’s waters.
NIWA meteorologist Nava Fedaeff also said there were 76 locations across the country that experienced a record or near-record warm winter.To put this winter’s record warmth in perspective, Ms Fedaeff delved into historic weather records and found that the last time New Zealand experienced a similar sequence of events was 50 years ago.
Dr Turner determined that using NIWA’s in-house, high resolution weather model, known as the NZCSM – New Zealand Convective Scale Model – could result in a fairer comparison across all golf courses.NZCSM mean wind speeds from the past four years were applied to the ratings calculation of almost 400 golf courses across the country.
