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 nature of the volcanic event and its global impacts on the oceans, atmosphere, lithosphere and the cryosphere are a matter of debate. Here we present a first overview of the time travel of the sound atmospheric pressure wave through the Antarctic continent based on in situ measurements, which represented a unique event observed through the polar ice sheet during the instrumental meteorological era.

- Marine viruses prevalent in seawater have been less studied regarding their movement from ocean surfaces to the atmosphere.
- A study found that 6.2% of viruses could be found in both the air-sea interface and rainwater, indicating selective enrichment and transfer of viruses, particularly from the surface microlayer and sea foams to the atmosphere.
- The presence of specific CRISPR matches suggests frequent interactions between marine prokaryotes and foreign viruses, supporting the idea that viruses can spread through the natural water cycle.
Size-fractionated particulate mercury (PHg) measurements were performed from November 2017 to January 2018 at Terra Nova Bay (Antarctica) for the first time. Samples were collected every 10 days by a six-stage high-volume cascade impactor with size classes between 10 μm and 0.49 μm.
