The @PurdueEAPS faculty are ready for football season! #boilerup #purduegameface

[Ben K. D. Pearce @AstroBio_Ben]

Big news: I'm moving to Indiana!

Next year, I'll be joining the faculty in the Earth, Atmospheric, and Planetary Sciences Department at Purdue University (@PurdueEAPS).

This really is a dream come true. (1/)

I’ve had a great time visiting with old friends and new collaborators at @AstrobiologyPsu this week! Penn State is such a special place ❤️

[PSUAstrobiology @AstrobiologyPsu]

We're lucky to be hosting @GeoscPSU alumna @ExoStephO today at Astrobiology Hour. It's a great turnout with students and postdocs from both @PSUEMS and @PSUScience https://t.co/kbNCYZI3al

Got on our #PurdueGameFace on 🚂☝️⁦@mikesori1⁩ ⁦@ExoStephO⁩

[Dr. Stephanie Olson @ExoStephO]

We are so excited and lucky that @rogbryant is joining @PurdueEAPS! I’m excited for the geochemical adventures to come and for his B1G indoctrination #boilerup 🚂

[Dr. Stephanie Olson @ExoStephO]

@JensTerhaar Even more modest of a change than that actually. Just increasing salinity to 50 g/kg (not by 50 g/kg) was enough to simulate warm Archean climates despite otherwise pessimistic assumptions!

[Dr. Stephanie Olson @ExoStephO]

Super excited for our new paper in GRL today! We show that salt 🧂 may be an important ingredient for habitability, on Earth 🌎 and beyond 👽

[Dr. Stephanie Olson @ExoStephO]

@JanDZika At least partially! AMOC strengthens w/ increasing salinity in present-day Earth scenarios. No AMOC in Archean w/o continents, but the ice line is stabilized at low lats against the ice-albedo feedback due to overturning at the ice margin, which strengthens w/ increasing salinity

[Dr. Stephanie Olson @ExoStephO]

@ElleChimiak My understanding is that hypersaline environments get a lot of attention from biosignature folks for favoring organic preservation over geologic timescales, so quite possibly yes!

[Dr. Stephanie Olson @ExoStephO]

@climatedynamics Just wait until you see what @kylebatra is up to!

[Dr. Stephanie Olson @ExoStephO]

@ElleChimiak I suppose high salinity could negatively affect mineral templating of organics… but also more ions might facilitate other reactions?? I have zero intuition for this problem, but agree it’s important!
