NIWA’s Crispin Middleton, an accomplished underwater photographer, was swimming last November in the Poor Knights Marine Reserve when he spotted a football octopus inside a salp.2020 Special Award Winner - Crispin Middleton for 'Football octopus catches a ride inside a salp'.
Voyage leader and NIWA marine geologist Dr Joshu Mountjoy says this is the first time this technology has been used to survey submarine canyons in New Zealand waters and information collected will lead to new understanding relevant to many of the world’s continental margins.
John Brosnan waits on board the RV Kaharoa after returning to New Zealand from an epic 75-day voyage.NIWA has deployed more than 1100 Argo floats in the Pacific, Indian and Southern Ocean over 22 voyages since 2004, more than any other individual vessel.
With COVID-19 having put a stop to all Pacific travel for now, NIWA field staff have had to work out how to carry out their jobs without actually being there, making mastering the art of delivering training and support via video call an essential skill.
The industry is looking to expand by farming in more exposed locations, but NIWA aquaculture scientist Dr Javed Khan says such growth is likely to be constrained unless new approaches are taken in the hatcheries that supply the juvenile fish to the farms.
NIWA hazards analyst Ryan Paulik, who led the assessment, says overall 430,000 people – or nine per cent of the population – live in the zones of which 170,000 are in red and orange zones.
However, NIWA fisheries scientist Dr Mark Morrison says no research was undertaken at the time of the closure of Separation Point to determine if the fish nurseries were present, nor has there been any since.
As the world battles a deadly pandemic, New Zealand school students have been beavering away at science fair projects researching the effectiveness of our own COVID-19 protection measures.NIWA freshwater ecologist and science fair coordinator Tracey Burton says that there is a strong focus on COVID-19 related projects entered in the fair.
Pelorus Ridge was officially granted its title by the New Zealand Geographic Board (NZGB) last week, along with 42 other place names for undersea features in New Zealand waters.Mr Mackay says the naming of Pelorus Ridge carries on a tradition of undersea features connected to NIWA.
The paper, written by Dr Stenton-Dozey along with NIWA scientist Jeffrey Ren, Phil Heath, formerly of NIWA, and Leo Zamora from the Cawthron Institute and published in the New Zealand Journal of Marine and Freshwater Research, had its origins in a four-year NIWA research programme into IMTA around salmon farms in the Marlborough Sounds.
NIWA scientists are heading to the waters around Whakaari/White Island in the Bay of Plenty next week to survey changes to the seafloor.No-one has collected water column imaging close to Whakaari so this is an incredible opportunity to discover new areas of volcanic activity.”.
NIWA climate scientist Dr Andrew Lorrey says that the volume lost from the Brewster Glacier in Mt Aspiring National Park is about equal to the basic drinking water requirements for all New Zealanders for those three years.
Last year NIWA air quality scientist Dr Ian Longley launched the Arrowtown project that included some outdoor monitoring and indoor air quality monitoring by people in their homes.
Before Samik came to work at NIWA he spent five and a half years as a post-doctoral researcher in the epidemiological modelling group at the University of Warwick.
As weather systems tracked toward New Zealand from the west and north, they lacked moisture because of cooler eastern Indian Ocean seas caused by the IOD.NIWA’s climate change expectations suggest spring average rainfall decreases for northern New Zealand, including Auckland.
Planning for this voyage has presented a few challenges for NIWA vessel operations manager Greg Foothead as he waited to hear if lockdown restrictions would be eased in time for the ship to leave.
And while conditions have improved in most regions, NIWA meteorologist Ben Noll says river flows and soil moisture levels remain below normal for large parts of the North Island and upper South Island while before last weekend drought still persisted in the Coromandel Peninsula.
Traffic pollution measurements in Auckland since Level 4 restrictions were eased on Tuesday have shown levels soaring even higher than those before lockdown, NIWA air quality scientists say.Nitrogen oxides have also returned to pre-lockdown levels in Christchurch but not as dramatically as Auckland.
The bushfires also caused a spike in carbon monoxide readings earlier in the year and last month NIWA scientists documented ash deposits on the South Island glaciers originating from the Australian fires.
High waves pounding Wellington’s south coast today are being caused by a deep area of low pressure passing the Chatham Islands, according to NIWA forecaster Ben Noll.Mr Noll said the low was responsible for generating strong winds and large waves between the Chathams and mainland New Zealand.
That was one of the findings in research, published this month in leading scientific journal Natural Hazards and Earth Science Systems, in which NIWA researchers describe how small increases in sea level rise are likely to drive huge increases in the frequency of coastal flooding in the next 20–30 years.
NIWA air quality scientist Dr Ian Longley says nitrogen oxide is found in pollutants from vehicle exhausts.Dr Longley says reductions in levels of airborne particulate matter have been more modest—for example a 20 per cent drop in fine particles (PM2.5) at Takapuna during daylight hours.
While the ship could have remained at sea until its intended return, NIWA vessels manager Greg Foothead said the decision was made to bring the ship back early so those on board could be reunited with families in the nationwide lockdown.
These are broadly defined as hazard monitoring, resilience, diagnostics for essential services like biosecurity, maintaining animal facilities, and infrastructure that requires constant attention (e.g., security of samples, collections and computing facilities), as follows.
Young New Zealanders can now access the most up-to-date educational material about the science of climate change and its impacts on Aotearoa thanks to NIWA’s new web section: .
NIWA marine geologist Dr Joshu Mountjoy says the discovery is one of the few times a significant offshore aquifer has been located around the world and may lead to a new freshwater resource for the region.
Journalists are invited to attend a media conference in Queenstown on Friday, March 6, starting at 10.15am at which scientists from NIWA and Victoria University of Wellington will outline the initial findings of the annual end-of-summer snowline survey taking place on March 5.
