Working with microbiology and exobiology colleagues in the Astrobiology Institute (principally, Brad Bebout), we have developed a "collaboratory" in a greenhouse atop Building 239. In this greenhouse, microbial algae mats collected from various astrobiology field sites are incubated and maintained in aquarium tanks. Using our collaboratory software, scientists can conduct remote experiments with individual mats, measuring oxygen concentration levels at various depth levels using a microsensor probe mounted on a motor above the aquarium. Our team has developed an interface to remotely schedule, control, and monitor these oxygen microsensor experiments over the web. The remote control setup interfaces with the ScienceOrganizer information repository, and the microsensor data is deposited directly into the system, where it can be remotely accessed with suitable permissions.
