New Martian valley network volume estimate consistent with ancient ocean and warm and wet climate
Abstract
To understand the early Martian climate, the volume of the global Martian valley network is required. Here, the authors use a black top hat transformation method and find that the minimum global valley network volume is 1.74 × 1,014 m3 with a minimum cumulative volume of water required of 6.86 × 1,017 m3.
