To understand these sightings, the forecasting team contacted their colleagues at the Lauder Atmospheric Research Station in Central Otago, who confirmed that their ground-based LIDAR (Light Detection and Ranging) instrument has been detecting unusual spikes in aerosols in the stratosphere, at around 20-25 kilometres above New Zealand.
These instruments, part of the National Oceanic and Atmospheric Administration’s Search and Rescue Satellite-Aided Tracking program (Sarsat), picked up the signal and immediately pinged alerts to Earth.
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.
Researchers from Sustainable Seas and Our Land & Water National Science Challenges are involved in a two-year project called Ki uta ki tai: Estuaries, thresholds and values, which includes interwoven critical steps funded by MfE.
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.
One controversial idea is known as bioenergy with carbon capture and storage, or BECCS: You’d grow crops and burn them for energy, then capture the emissions coming out of the facility and pump them underground as liquefied gas.
“If you don’t have water, you’re not going to get very far.” Making sense of that subglacial hydrology is especially important for researchers racing to model particularly precarious regions of ice, like the Thwaites Glacier, a few hundred miles away from Whillans.
Using off-the-shelf accelerometers, researchers have been quantifying how trees sway differently over time: when they’re warmer or colder, hydrated or dehydrated, weighed down by snow or unburdened.But with accelerometers, scientists have a new way of measuring how much rain or snow a particular tree in a forest ends up intercepting.

Studies from the Natural Resources Defense Council (NRDC) have found that more than 100 billion kilowatt-hours are wasted every year because of vampire energy, “costing American consumers over $19 billion—about $165 per US household on average—and 50 large (500-megawatt) power plants’ worth of electricity.”.
© Chuck Peoples / TNC In 1989, the Conservancy purchased 10,626 acres along the river that became the Roanoke National Wildlife Refuge.Since 2002, the Conservancy has worked with the Corps of Engineers on dam releases that mimic natural flows, providing pulses of water to the floodplain forest that provide for vegetation and fish migration and spawning.
Changes in salinity, temperature, and pressure change how the sea sounds, with unknown impacts on the life-forms that depend on that noise to survive.
The new species of jumping slug was found in the same area and habitat as TNC’s Ball Creek Ranch Preserve, Idaho.
By late February, the dam operators were releasing more than 400 acre-feet per hour into the lower river—enough water to flood 400 acres of grapes or almonds shin-deep.

“I think it's just absolutely remarkable that there are places on the seafloor where changes of this scale are happening at this rate,” says Monterey Bay Aquarium Research Institute marine geologist Charlie Paull, a coauthor on the paper.
Giant Redfin: Conserving South Africa’s Native Fish.Giant redfin and other freshwater species in the Cape Region face significant challenges.And the litany of challenges they face will be familiar to freshwater conservationists everywhere: invasive species, pollution, water quantity and habitat degradation.
That’s why the Conservancy and partners are working together on the Rio Grande Water Fund that generates funding for a 20-year program to restore 600,000 acres of forests in northern New Mexico and southwestern Colorado.
The health effects of these kinds of wartime incidents are likely to be felt long after the physical conflict subsides, says Doug Weir, director of research and policy at the UK-based Conflict and Environment Observatory.
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.
Last week, a group of federal agencies released a report detailing the dire state of sea level rise in the United States: On average, it projects up to 12 additional inches in the next 30 years, the same amount that the country has seen in the last century.

Conserving salamanders and other underground life is a “huge deal,” said Tovar, “because they rely on the water that we rely on.” The health of underwater ecosystems can act as a barometer for the health of everything living aboveground, too, including people.
