V024: Quaternary and Neogene Hotspot Volcanism on the Cretaceous Kerguelen Plateau, Southern Indian Ocean: Nature and Potential Environmental Impact
The Kerguelen Plateau, a large
igneous province (LIP) of predominantly Cretaceous age in the southern
Indian Ocean, has experienced widespread Quaternary and Neogene hotspot
volcanism. Loci of this younger magmatism
include not only the Kerguelen Isles, Heard Island, the McDonald
Islands, and the seafloor surrounding these islands, but also broad
areas elsewhere on the Central Kerguelen Plateau. Recent data and
samples acquired from the seafloor, islands, and water column
are illuminating the origin, age, and distribution of the Quaternary
and Neogene hotspot volcanism as well as its role in supplying iron to
the anemic Southern Ocean. Phytoplankton, which produce approximately
half of the oxygen in the Earth’s atmosphere,
require iron to metabolize and bloom. This multidisciplinary session
aims to foster better understanding of young hotspot volcanism in the
Southern Ocean and its potential role in supplying iron to surface
waters where it nourishes phytoplankton.
