Depth-related differences in organic substrate utilization by major microbial groups in intertidal marine sediment.
Stable isotope probing of magnetic-bead-captured rRNA (Mag-SIP) indicated clear differences in in situ organic substrate utilization by major microbial groups between the more oxidized (0 to 2 cm) and sulfate-reducing (2 to 5 cm) horizons of marine intertidal sediment. We also showed that cyanobacteria and diatoms may survive by glucose utilization under dark anoxic conditions.

بیمه گران همیشه بابت خسارات بیمه نامه های تحت پوشش خود نگران بوده و روش هایی را جستجو می کنند که بتوانند داده های خسارات گذشته را با هدف اتخاذ یک تصمیم بهینه مدل بندی نمایند. در این پژوهش توزیع های فیزتایپ در مدل بندی داده های خسارات معرفی شده که شامل استنباط آماری مربوطه و استفاده از الگوریتم em در برآورد پارامترهای توزیع است. در پایان امکان استفاده از این توزیع در مدل بندی داده های گروه بندی ...
Geotechnical Properties of Lacustrine Carbonate Sediment
Results of laboratory tests on specimens produced from subsoil studies were evaluated tocharacterize geotechnical properties of Tabriz Marl. It was concluded that, Tabriz Marl may be considered as a high liquid limit silt or clay (MH & CH). Range of changes of index, physical and mechanical properties of the Tabriz Marl are comparatively vast. Correlation between these properties has been intro...
متن کاملEvaluating optical lightness as a proxy for carbonate content in marine sediment cores
Optical lightness is increasingly being used as a proxy for the carbonate content of marine sediment. We compared three measurements of optical lightness, gray scale, brightness and L, to carbonate content to test the reliability of these Ž . measurements as carbonate content proxies. In five piston cores from isotope stages 1 though 6 0–;130 ka , all measures of optical lightness are reasonabl...
متن کاملAn abyssal carbonate compensation depth overshoot in the aftermath of the Palaeocene–Eocene Thermal Maximum
1 The PETM represents one of the largest and most abrupt greenhouse warming events in Earth’s history. Marine and terrestrial records document a global >2.5‰ negative carbon isotope excursion (CIE; refs 1–3) coincident with global mean surface ocean warming of >4 °C (ref. 4) and geochemical and sedimentological evidence for ocean acidification5,6. Collectively, these lines of evidence suggest a...
