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...
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...
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...
