As my colleague David M. Herszenhorn reports, scientists are poised to take some highly anticipated samples from a deep subglacial lake in Antarctica, saying on Wednesday that they had succeeded in boring through more than two miles of ice.
We took a water sample from a mile deep in the Earth from some coal mines in Colorado, and we knew there was life there, but we didn't know to what extent and how much diversity there would be.
In the present study, X-ray diffraction (XRD) analysis, scanning electron microscope (SEM), and mercury intrusion porosimetry experiments were carried out to investigate the mineral compositions, microstructure and porosity characteristics of the 13 clay-bearing soft rock samples collected from a deep coal mine in China.
Parts of the sediment record from the core sample indicate a deep lake with lacustrine silts and clays and freshwater fossils.
Microbial assemblages were sampled from an offshore deep sub-surface petroleum reservoir 2.5 km below the ocean floor off the coast of Norway, providing conditions of high temperature and pressure, to identify new thermostable enzymes.
"My Crib" uses the same Moments sample as on Jay Z's "You, Me, Him and Her"; "Henny" uses a bouncy sample from Mobb Deep's "Learning (Burn)"; "Own It" samples the seminal "Eric B. Is President".
He was hoping to extract an ice core — a sample from deep inside the glacier, which would provide a detailed picture of the area's past climate.
d Rough growth surface of dark crystalline Mg-calcite scale-fragment precipitated inside a pipe (sample KIR33 collected from a deeper production well section).
Prevalence of childhood sexual abuse and physical trauma in an HIV-positive sample from the deep south.
At each site, two samples were taken; one from a depth of 0 25 cm and a second, deeper sample from a depth greater than 100 cm or the deepest part of horizon C as possible as we can take.
