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.
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).
For scientist Sophie Gilbert, who spent four recent summers tracking the movements of Sitka black-tailed deer in the Tongass National Forest in a project with the Alaska Department of Fish and Game, that means notebooks with waterproof paper.
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.
Ten-thousand miles away in England, Simon Proud, a satellite data researcher at the University of Oxford, began to monitor the twitching volcano using an array of satellites.Then, early in the morning on January 14 local Tongan time, a 12-mile-high plume of ash pierced the sky.
Like the popular Summer Heights High (and its spinoffs, Ja’mie: Private School Girl and Jonah from Tonga , which was pulled from the air in 2017 for being racist), Lunatics is a mockumentary following a bevy of characters all played by Lilley.
