Episodic ocean-induced CO2 greenhouse on Mars: implications for fluvial valley formation.
Pulses of CO2 injected into the martian atmosphere more recently than 4 Ga can place the atmosphere into a stable, higher pressure, warmer greenhouse state. One to two bar pulses of CO2 added to the atmosphere during the past several billion years are sufficient to raise global mean temperatures above 240 or 250 K for tens to hundreds of millions of years, even when accounting for CO2 condensat...
متن کامل[Severe hemorrhagic form of Rift Valley Fever in Mauritania].
We report three severe cases of hemorrhagic form of Rift Valley Fever which have been observed in the Hospital of Aïoun (two cases) and in the regional hospital of Tidjikdja (one case). The disease manifested itself by an infectious syndrome, an early infectious syndrome (on the second day) with onset of hemorrhagic complications and disorder of consciousness ranging from an agitation to deep c...
متن کاملClimate-driven fluvial development and valley abandonment at the last glacial-interglacial transition (Oude IJssel-Rhine, Germany)
In the Weichselian, the Lower Rhine in the Dutch-German border region has used three courses, dissecting ice-marginal topography inherited from the Saalian. In the Late Weichselian, the three courses functioned simultaneously, with the central one gaining importance and the outer ones abandoning. This study aims to reconstruct the fluvial development and forcings that culminated in abandonment ...
متن کاملThe fluvial history of Mars.
River channels and valleys have been observed on several planetary bodies in addition to the Earth. Long sinuous valleys on Venus, our Moon and Jupiter's moon Io are clearly formed by lava, and branching valleys on Saturn's moon Titan may be forming today by rivers of methane. But by far the most dissected body in our Solar System apart from the Earth is Mars. Branching valleys that in plan res...
متن کاملThe Response of Fluvial Systems to Large Flood Events
In the summer of 2001, an intense thunderstorm in southeastern Caspian Sea triggered a catastrophic flood in the Madarsoo basin . Use of methods including high-resolution aerial photographs and satellite images interpretation, multi-date mapping, hydraulic calculations and field observations made possible the documentation of the geomorphic impacts on the Madarsoo River and its tributaries. Geo...
