AbSciCon 2015 Abstracts

Twenty abstracts from eight different RPL labs (Boyd, Brazelton, Cardace, Hoehler, McCollom, Schrenk, Shock, Templeton) were submitted for presentation at AbSciCon 2015. Sixteen of these were submitted toThe Habitability of Water-Rock-Supported Ecosystems session organized by RPL PI Alexis Templeton.
