Baffin Island Provides Insights into Origin of Earth's Water (1 of 3)

Caption

An aerial photograph showing the most recent eruption at the Holuhraun lava field in Iceland. This eruption was fed directly from the Iceland mantle plume, and a proportion of the gas emitted is thought to be water vapor sourced from this plume. We measured Baffin Island and Icelandic rocks where plume water was trapped inside the rocks, rather than being degassed into the atmosphere.
