The Electric Sands of Titan
Electric Sands Titan
2017/3/30
Experiments led by researchers at the Georgia Institute of Technology suggest the particles that cover the surface of Saturn’s largest moon, Titan, are “electrically charged.” When the wind blows hard...

Transformation and fate of microphytobenthos carbon in subtropical shallow subtidal sands: A 13C-labeling study
Transformation fate of microphytobenthos carbon subtropical shallow subtidal sands A 13C-labeling study
2014/4/2
Microphytobenthos (MPB) in photic sediments are highly productive but the fate of this production remains uncertain. Over 33 d, tracing of 13C from added bicarbonate in subtropical shallow subtidal sa...
Carbon cycling hysteresis in permeable carbonate sands over a diel cycle: Implications for ocean acidification
Carbon cycling hysteresis permeable carbonate sands over a diel cycle ocean acidification
2014/4/2
Dissolved inorganic carbon, dissolved oxygen, H+, and alkalinity fluxes from permeable carbonate sediments at Heron Island (Great Barrier Reef) were measured over one diel cycle using benthic chambers...

Quantifying denitrification in rippled permeable sands through combined flume experiments and modeling
Quantifying denitrification rippled permeable sands combined flume experiments modeling
2014/4/4
We measured denitrification in permeable sediments in a sealed flume tank with environmentally representative fluid flow and solute transport behavior using novel measurements. Numerical flow and reac...
Some regolith and landscape evolution highlights from the Murray Basin's Loxton Parilla sands
regolith landscape evolution highlights the Murray Basin Loxton Parilla sands
2012/3/30
The Loxton-Parilla Sands formation provides a well-constrained geological record of the Late Miocene – Early Pliocene marine regression from the western Murray Basin (Miranda et al. 2009). It presents...
Variable sources of beach sands of north Adriatic islands:examples from Rab and Susak
beach sands sediment supply framework composition heavy mineral Rab Susak Croatia
2009/12/7
The composition of beach sands from the Islands of Rab and Susak (northern Adriatic) has been studied in order to determine how individual beaches are supplied with detritus. The beaches on both islan...
Discriminant Function Analysis of Upper Miocene and Pliocene Sands from the Southwestern Part of the Pannonian Basin System,Croatia
Discriminant function analysis heavy mineral association lithostratigraphic units Upper Miocene
2009/12/7
Multiple discriminant analysis (MDA) of Upper Miocene and Pliocene sands of SW portion of Pannonian Basin System is performed in order to find out optimum criteria of separating previously defined inf...
Identification of phytodetritus-degrading microbial communities in sublittoral Gulf of Mexico sands
phytodetritus-degrading microbial communities Mexico sands
2014/4/18
We identified microbial taxa that catalyze phytodetritus degradation and denitrification in permeable coastal
sediments of the northeast Gulf of Mexico. Stable isotope probing experiments were used t...
Construction of three-dimensional geological models for oil sands reservoirs in Athabasca, Canada
oil sands geological model acoustic impedance inversion multi-attribute analysis
2009/3/5
Three-dimensional geological models were constructed by integrating well and seismic data from the oil sands area of Athabasca, Canada. For the production of bitumen from the reservoir 200 to 500 mete...
Wave friction factors are estimated from vertical profiles of near-bed turbulence and horizontal velocity spanning the wave bottom boundary layer. Measured values are partitioned by bed state, which r...
Selection by a deposit-feeding polychaete,Polygordius jouinae, for sands with relatively high organic content
deposit-feeding polychaete Polygordius jouinae sands relatively high organic content
2014/4/18
Field observations and flume experiments investigated whether subsurface migration and selection by adult Polygordius jouinae for sediment enriched with organic flocs could help explain small-scale pa...
13 November 2006，Physicists in Germany have turned their attention to an age-old challenge facing desert dwellers -- how plants can be used to stop moving sand dunes. The researchers defined equations...
