Study on methane in deep-sea sediments shows small releases happen more often than thought（图）
深海沉积物 甲烷 化石生物 单细胞生物
2023/6/26
New research describes evidence that deep sea methane deposits change into gas more frequently than could be monitored previously and that a set of fossilized organisms has a unique ability to detect ...
Deep-sea sediments lead to new understanding of solar system（图）
Deep-sea sediments new understanding solar system
2019/10/18
A day is the time for Earth to make one complete rotation on its axis, and a year is one revolution around the Sun -- reminders that basic units of time and periods on Earth are intimately linked to o...
Anaerobic ammonium oxidation in deep-sea sediments off the Washington margin
deep-sea sediments off Anaerobic ammonium
2014/4/17
The significance of anaerobic ammonium oxidation (anammox) for nitrogen removal in deep continental
margin sediments was studied with 15N amendments to suboxic sediments collected from 2800–3100-m wa...

14C excess in deep-sea sediments porewater driven by diffusion—Southeast Mediterranean
14C excess deep-sea sediments porewater driven by diffusion— Southeast Mediterranean
2014/5/26
Core profiles in the deep SE Mediterranean Sea revealed a significant Δ14C excess in the total dissolved inorganic carbon (DIC) of porewater as compared to the Δ14C of the sediments, below the bioturb...
What controls the mixed-layer depth in deep-sea sediments? The importance of POC flux
mixed-layer depth deep-sea sediments The importance of POC flux
2014/5/26
The depth of biogenic particle mixing, i.e., the mixed-layer depth (L), is fundamental in models of organic-matter recycling and paleoreconstructions for deep-sea sediments. Factors postulated to cont...
Zeolite Distribution in Volcaniclastic Deep-sea Sediments from the Tonga Trench Margin (SW Pacific)
Analcime Miocene tuffs Mordenite Pore-water Thermal pulse Tonga Trench margin Wairakite Zeolite distribution
2011/12/1
Abstract: 605 m of sediments were cored in Hole 841 of the Ocean Drilling Program (ODP) at the Tonga Trench margin. The sedimentary sequence consists mainly of Miocene vitric siltstones, vitric sandst...
Isothermal Diffusion of Eu and Th in Deep-Sea Sediments: Experimental Results and a Numerical Model
Deep-sea sediments Diffusion Europium Partition coefficient Sorption Thorium
2012/1/12
Batch data for the sorption of Eu and Th on pelagic sediments may be represented by equations of the form: ln M = A ln Cs + B/T + D, where M = concentration of sorbate on sediment, Cs = concentration ...
A Method for the Quantitative Estimation of Clay Minerals in North Pacific Deep-Sea Sediments
Clay Distribution Clay Quantification Deep-sea Pacific X-ray Methods
2012/2/9
The addition of a 10% talc internal standard to North Pacific sediments allows the relative abundances of clay minerals to be determined both accurately and precisely by X-ray powder diffractometry. L...
