Oceans Across Space & Time (OAST) is part of NASA's Network for Life Detection. We study how ocean worlds might evolve into detectable life, past or present.

Great video of our collaboration with ETNTAC by Rhys Guilfoyle! We miss Esperance and all the salt lakes already!!

Our very own Emily R. Paris, along with the Society for Women in Marine Science, wrote a blog post on our Orca Basin fieldwork! Check it out!

And we're done! Over 12 days, we conducted 21 CTD casts, 11 ROV dives, collected 10 sediment cores (they said it couldn't be done!), and a considerable number of water column samples. Huge thanks to everyone for making this a reality. On to the real work! #nasaastrobiology

DHABs like Orca Basin provide essential information on the coevolution of biological communities and their geologic niches, and on the limits of life under conditions relevant to contemporary oceans on Europa, Enceladus, other icy moons, and past oceans on Mars. #NASAAstrobiology

The Dekas Lab started 168 stable isotope incubations with water from sites around the South Bay Salt Works. Using samples from lakes with different salts - from sodium chloride to magnesium chloride - they’ll mimic environmental conditions to see how the samples respond.

Brine time! Returning to South Bay Salt Works in Chula Vista, CA, our team collected samples from different salt ponds and the Otay River. The samples are being studied by team members across the country - some samples arrived in Atlanta to be filtered, a slow process!

At the Basque Lakes in Canada, OAST is investigating hypersaline lakes with diverse brine chemistries that may mirror those of several of NASA’s high priority astrobiology targets such as Europa, Enceladus, and Mars! #ResearchSpotlight

OAST Co-Investigator Jen Glass has a great home office space for contemplating the nitrogen cycle! #RemoteSciencing #SociallyDistancedScience

Looking for life in pink and green salt ponds at the South Bay Salt Works is very similar to the challenge of life detection on other planets. “These ponds will break any instrument that you put in them” said Jeff Bowman, OAST deputy PI.

How do different salts and concentrations impact the search for life on other worlds? Join the OAST team as we take a look at the South Bay Salt Works lakes in Chula Vista, California!

Our friends @IcefinRobot and others are doing a Twitter Q&A today with @BulletinAtomic in the #ThwaitesGlacierChat!
@GlacierThwaites is one of the fastest changing glaciers in Antarctica. We want to understand how that works, and how quickly #ClimateChange is affecting the glacier. #ThwaitesGlacierChat

This is one of the ice cores the OAST team got from hypersaline lakes in British Columbia. You can see brine channels at the base of it (two circles that look like little bubbles). These porous regions are where solutes and biology can be transported through the ice.
