Merging isotopes and community genomics in a siliceous sinter-depositing hot spring.
(American Geophysical Union, 2011-01)
Thermophilic microbes in hydrothermal ecosystems have multiple metabolic strategies for taking up carbon and nitrogen, which may result in distinct stable isotopic compositions of C and N in living biomass, as well as other ...
Mantle Flow Beneath Arabia Offset from the Opening Red Sea
(American Geophysical Union, 2011-02-16)
Continental rifting involves a poorly understood sequence of lithospheric stretching, volcanism, and mantle flow that evolves to seafloor spreading. We present new insight from inversion of seismic traveltimes and waveforms ...
Spectroscopic study of the cycling transition 4s[3/2](2)-4p[5/2](3) at 811.8 nm in Ar-39: Hyperfine structure and isotope shift
(American Physical Society, 2011-01-24)
Doppler-free saturated absorption spectroscopy is performed on an enriched radioactive Ar-39 sample. The spectrum of the 3s(2)3p(5)4s[3/2](2)-3s(2)3p(5)4p[5/2](3) cycling transition at 811.8 nm is recorded, and its isotope ...
