Atm Loss from Ar Isotopes
The ratio studied by MAVEN for the Jakosky (2017) paper.
What is the 38Ar/36Ar ratio?
This process likely both brought and removed atmosphere during the Noachian, making it's net effect challenging to estimate.
What are/is impacts/bombardment?
This is the thickness an amount of water would have if it were spread evenly over Mars (words, not acronym).
What is Global Equivalent Layer?
Characteristic about argon makes it an ideal gas for studying atmospheric loss?
What is chemically inert?
What is it has one sputtering mechanism?
What is it has measurable diffusive separation?
Carbon dioxide reservoir that would be the easiest to reach if terraforming Mars were to happen
What are the polar ice caps?
Mars lacks this, causing crustal hydration to be a permament process unlike on Earth.
What are plate tectonics?
Indicator of gains to space
What is light-isotope enrichment?
This non-chemical reaction adheres CO2 molecules to regolith particles on or near the surface.
What is adsorption?
This is the size of the Noachian ocean proposed at the beginning of Scheller 2021.
What is 100-1500m GEL?
Instrument that directly measures the composition of and isotopes of neutral gases and ions in the upper atmosphere during deep-dip orbits.
What is the Neutral Gas and Ion Mass Spectrometer (NGIMS)?
The least likely scenario for determining the amount of carbon dioxide that can be sequestered when assessing a carbonate reservoir size.
What is the carbonate unit extent extrapolated to include the entire Isidis melt sheet?
This is the ratio that constrains the amount of water that could have been lost to space from the beginning of the Noachian to now.
What is the D/H ratio?
What is the Rayleigh equation?
The crater where deep carbonates were first identified on the central peak.
What is the Leighton Crater?
These three reservoirs make up the Exchangeable Reservoir used by the authors to model the currently available water on Mars.
What are the atmosphere, ice, and liquid water?
