The springs exhibit stable temperatures with time and season, averaging about 17±1°C.
“The springs exhibit stable temperatures with time and season (spring vs. fall), averaging about 17±1 ˚C (Morrill et al., 2013; Suzuki et al., 2013).”

Morrill et al. (2013) identified two types of ultrabasic water at The Cedars that variably mix: deep flow-path waters enriched in K+, salinity, and volatile organic compounds, and shallow path waters with lower salinity and [K+].
“They identified two types of ultrabasic water at The Cedars that variably mix: (1) waters with deep flow-paths that interacted with the underlying Franciscan Complex enriching the waters in K + , salinity, and volatile organic compounds before encountering ultramafic rock, and (2) waters with shallow paths that pass solely through ultramafic rock and are characterized by lower”

Applying the aragonite precipitation rate equation to the observed growth range for a temperature of 17.4°C yields an aragonite saturation state Ω of ~9 to 13.
“Applying this equation to the observed growth range above for a tempera ture of 17.4˚C (Morrill et al., 2013) yields a Ω of ~ 9 to 13.”

The one measurement of δ13C of BSC pool water DIC gives a value of -31.5‰ (VPDB), about 5‰ lighter than the lightest values recorded by the CaCO3 and consistent with near complete conversion of CO3 2- to CaCO3.
“It may be significant that the one measurement of δ 13 C of BSC pool water DIC gives a value of -31.5‰ (VPDB; Morrill et al., 2013), which is about 5‰ lighter than the lightest values recorded by the CaCO3 and consistent with near complete conversion of CO3 2 -to CaCO 3 .”

The calculated Ω of ~9 to 13 compares well with Ω estimates by Morrill et al. (2013) of 13 for BSC and 5 for GPS based on measured ion chemistry.
“This compares well with the Ω estimates made by Morrill et al. (2013) of 13 for BSC (where our growth rate was measured) and 5 for GPS based on measured ion chemistry.”

“Geochemical conditions in the mafic and ultramafic crust hosting the present deep biosphere, even when obducted, can have hardly changed in the last 4 billion years and thus might provide indications of what the oldest inhabitants of the planet were like (Thauer et al., 1977; Morrill et al., 2013).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
