Volcanic ash as a source of nutrients: How the Hunga Tonga eruption affected ecosystems in the South Pacific
The eruption of Hunga Tonga-Hunga Ha'apai (HTHH) in January 2022 ejected about 2.9 billion tons of volcanic material into the atmosphere and across the South Pacific. In early 2022, a scientific expedition (GEOTRACES GP21) investigated the impact of this monumental event on the biogeochemistry of the South Pacific Gyre (SPG) surface waters.
