The Hunga Tonga-Hunga/Hunga-Ha'apai eruption on January 15, 2022 sent off a plume of ash material up to the stratosphere and triggered a meteotsunami and … barometric pressure pulse that rippled through the atmosphere and oceans all around the world.
The Hunga Tonga–Hunga Ha?apai volcano erupted on 15 January 2022, launching Lamb waves and gravity waves into the atmosphere. In this study, we present results using 13 globally distributed meteor radars and identify the volcanogenic gravity waves in the mesospheric/lower thermospheric winds.
On January 15, 2022, an ongoing eruption at the Hunga-Tonga Hunga-Ha'apai volcano generated a large explosion which resulted in a globally observed tsunami and atmospheric pressure wave.
Estimates of the distribution and density of Antarctic krill (Euphausia superba Dana, 1850) were derived from a large-scale survey conducted during the austral summer in the Southwest Atlantic sector of the Southern Ocean and across the Scotia Sea in 2018–19, the '2018–19 Area 48 Survey'.
This paper provides an overview of the deployments of Conductivity, Temperature and Depth (CTD) loggers and Benthic Video Cameras (BVCs) to fishing gear in the Dissostichus mawsoni exploratory fishery in Divisions 58.4.1 and 58.4.2 since 2015/16.
Exploratory fishing for Antarctic toothfish (Dissostichus mawsoni) in East Antarctica (Divisions 58.4.1 and 58.4.2) began in 2003. Since 2017/18, exploratory fishing has been conducted under successive research plans by Australia, France, Japan, Republic of Korea and Spain. Here…

Previous studies of Antarctic mosses … employing RAPDs have reported extraordinarily … high levels of genetic variation, even within a single … clump of moss. This is unexpected given their … extreme isolation in Antarctica and lack of sexual … reproduction. We offer an alternative explanation:
Iron(III)-uptake mechanisms in bacteria indigenous to the Antarctic, which is the most Fe-deficient … continent on Earth, have not been extensively studied. The cold-adapted, Antarctic bacterium, Shewanella gelidimarina, does not produce detectable levels of the siderophore, putrebactin…
Abstract. The discovery of an abundance of microorganisms that flourish in a diverse range of environments, from the frigid waters of the Antarctic, to the superheated waters of the hydrothermal vents, at the bottom of 11-km … deep ocean trenches and in salt-saturated lakes…
Beaufort Island, Ross Sea, Antarctica, is a Specially Protected Area originally designated on account of, and still supporting, a small winter sea ice breeding colony of Emperor penguins, a large summer breeding colony of Adélie penguins, and several colonies of Skuas. A substantial area of moss…
