    Abstract

    Liquid water was abundant on Mars during the Noachian and Hesperian periods but vanished as the planet transitioned into the cold, dry environment we see today. It is hypothesized that much of this water was either lost to space or stored in the crust. However, the extent of the water reservoir within the crust remains poorly constrained due to a lack of observational evidence. Here, we invert the shear wave velocity structure of the upper crust, identifying a significant low-velocity layer at the base, between depths of 5.4 and 8 km. This zone is interpreted as a high-porosity, water-saturated layer, and is estimated to hold a liquid water volume of 520–780 m of global equivalent layer (GEL). This estimate aligns well with the remaining liquid water volume of 710–920 m GEL, after accounting for water loss to space, crustal hydration, and modern water inventory.

    Proton’s statement from the linked article

    “We are aware of the Spanish terrorism case involving alleged threats to the King of Spain, but as a general rule, we do not comment on specific cases. Proton has minimal user information, as illustrated by the fact that in this case, data obtained from Apple was used to identify the terrorism suspect. Proton provides privacy by default and not anonymity by default because anonymity requires certain user actions to ensure proper OPSEC, such as not adding your Apple account as an optional recovery method.”











  • From my experience, kids can be some of the cruelest people just to fit in/be funny/feel superior at the cost of others. It’s a part of your past and you can’t change that, but you can change who you’ll become. It’s not easy being a good person and you’re going to have tough choices to make, but it’s the right thing to do.

    I do understand that abused kids have a higher tendency to abuse others and that is a more complicated issue that this statement does not pertain to.

    I also concede that there are kids that never grow up, unfortunately.
