Geological and Climate History of Mars: Identification of Potential Warm and Wet Climate 'False Positives' [#1731]
We outline an atmospheric evolution scenario with only modest decrease in P_atm and MAT; some geomorphic indicators of warm/wet climates may be “false positives.”

Planetary Scale Groundwater and Surface Water Interaction on Early Mars [#2415]
We present constraints for non-linear coupling of early martian groundwater and a putative ocean using the Boussinesq approximation and mass conservation.

Global Scale Martian Geomorphological Statistics Reveal an Integrated Noachian Hydrosphere [#1094]
Statistics derived from small [2–5]-km-diameter craters and VNs reveal an energetic integrated, dynamic Noachian hydrosphere, global water table, and no LNIH.

Differences in Fluvial Geomorphology Between Earth and Mars [#1562]
This study investigates how fluvial sediment transport is different on Mars and how these differences affect fluvial geomorphology and stratigraphy.

Martian Valley Networks and Their Lack of Headwater Catchment Areas [#1014]
Martian valley networks are evidence of ancient river flows on Mars. They are immature. We examine their topography to see if it limited their incision.

Noachian Valley Network Densities Track Ancient ITCZ Fluvial Precipitation [#1005]
Martian VN density supports a “cool and moist” low latitude climate consistent with the existence of a Noachian Intertropical Convergence Zone (ITCZ).

Global Spatial Distribution of Hack’s Law Exponent on Mars and Its Early Climate [#1540]
New algorithm used to delineate watersheds on Mars; Hack’s law exponent most similar to that of arid regions on Earth, implying early arid climate on Mars.

Bamber E. R.* Goudge T. A. Fassett C. I. Osinski G. R. Stucky de Quay G.

Factors Controlling Which Craters Developed Inlet Valleys on Early Mars [#1062]
Water trickling / Over crater rims, high, low? / How does it carve so?

Hesse M. A.* Shadab M. A. Hiatt E.

Timescales for Terminal Groundwater Drainage from the Southern Highlands on Mars [#1637]
We present a model for the terminal drainage of martian groundwater from the southern highlands and show that the time scale is a billion years.

Shadab M. A.* Hiatt E. Hesse M. A.

Investigating Groundwater Dynamics and Residence Times on Early Mars Using Unconfined Aquifer Model with Vertical Heterogeneity [#1736]
We develop an analytic model of a crustal aquifer with vertical heterogeneity on early Mars to study the groundwater dynamics and residence times.

Scheidt S. P.* Crown D. A. Berman D. C. Williams D. A. Bernhardt H.

Mapping Fluvial Systems on Martian Volcanoes: Investigations of Alba Mons and Amphitrites Patera [#2872]
We present and compare mapping from our investigation of Alba Mons fluvial networks and introduce a new mapping investigation on Amphitrites Patera, Mars.

Crater-Based Surface Age Dating of the Osuga Valles Region, Mars [#2895]
Water flows / Asteroids go splat / Statistics!

Constraining Sources and Sinks of Hydrated Minerals in the Uzboi-Landon-Morava Outflow System, Mars [#2331]
Where did you come from / Where did you go, all that clay / From so long ago.

Dundas C. M.* Keszthelyi L. P. Williams K. E.

Modeling the Reach of Floods in Athabasca Valles, Mars [#2470]
Were rootless cones near the martian equator the result of a flood or atmospheric ice deposition? Flood models can help.

Baran Z. J.* Cardenas B. T.

Numerical Simulations of Lake Bonneville Shoreline Erosion at Mars-Like Rates and Durations [#2697]
Preserved Mars shorelines / The small erode away, but / The larger ones last.

Evolution History of Mesas in the Southern Utopia Planitia and Implications for the Ancient Oceans on Mars [#1237]
We investigate the detailed morphological characteristics of the mesas on the lHl unit within the Utopia Planitia, and have an interesting insight.

Parker T. J.* Bills B. G.

The Mars Ocean Hypothesis: Objectives and Preliminary Results [#2963]
Mapped shorelines define nearly-planar surfaces averaged, but the local details show scatter of tens to hundreds of meters over distances of kilometers to tens of kilometers.

Soldano V. A.* McCoy S. W. Calvin W. M. Adams K. D.
