THEO Concept Mission: Testing the Habitability of Enceladus's Ocean

, 2016
Saturn's moon Enceladus offers a unique opportunity in the search for life and habitable environments beyond Earth, a key theme of the National Research Council's 2013-2022 Decadal Survey. A plume of water vapor and ice spews from Enceladus's south polar

Detection of microbes in the subsurface [PDF]

The search for evidence of microbial life in the deep subsurface of Earth has implications for the Mars Rover Sampling Return Missions program. If suitably protected environments can be found on Mars then the instrumentation to detect biomarkers could be

Continuous Injection of Hydrogen Peroxide in Drip Irrigation—Application to Field Crops

Agronomy
Drip irrigation offers greater water use efficiency than conventional furrow irrigation practises, though routine maintenance is required for optimal performance. The continuous use of low concentrations (10 ppm) of H2O2 stabilized with hydroxyethylidene

Ecology of Thioploca spp.: Nitrate and sulfur storage in relation to chemical microgradients and influence of Thioploca spp. on the sedimentary nitrogen cycle

, 2001
Microsensors, including a recently developed NO3 − biosensor, were applied to measure O2 and NO3 − profiles in marine sediments from the upwelling area off central Chile and to investigate the influence of Thioploca spp.
