D/H Ratio in Water and the Origin of Earth’s Oceans

Abstract
Measurements of the D/H ratio in cometary water provide key constraints on the origin and history of water, and the contribution of comets to Earth’s oceans. Measurement of the D/H ratio in a statistically significant sample of comets is as a high-priority goal for the next decade, important for understanding Earth’s habitability.
