Rates of carbonate dissolution in permeable sediments estimated from pore-water profiles: The role of sea grasses
carbonate dissolution permeable sediments estimated pore-water profiles sea grasses
2014/4/21
In this study we estimate sediment carbonate dissolution rates for sandy sea grass sediments on the Bahamas Bank using an inverse pore-water advection/diffusion/reaction model constrained by field obs...
Dissolution of biogenic silica from land to ocean: Role of salinity and pH
Dissolution of biogenic silica land to ocean salinity pH
2014/4/18
The dissolution rates of diatom frustules, phytoliths, two diatomaceouslake sediments, a siliceous ooze from the Southern Ocean, a diatomite deposit, and a synthetic amorphous silica were measured in ...

CO32− concentration and pCO2 thresholds for calcification and dissolution on the Molokai reef flat,Hawaii
CO32− concentration pCO2 thresholds calcification dissolution
2010/1/13
The severity of the impact of elevated atmospheric pCO2 to coral reef ecosystems depends, in part, on how seawater pCO2 affects the balance between calcification and dissolution of carbonate sediments...
Physical and chemical predictors of diatom dissolution in freshwater and saline lake sediments in North America and West Greenland
Physical and chemical predictors diatom dissolution in freshwater saline lake sediments North America West Greenland
2014/5/4
Diatom dissolution in surface sediment samples from two regional lake datasets in the Northern Great Plains (NGP; n = 64) and West Greenland (n = 40) is assessed using a morphological approach categor...
Effects of surface roughness and oscillatory flow on the dissolution of plaster forms: Evidence for nutrient mass transfer to coral reef communities
surface roughness oscillatory flow dissolution of plaster forms nutrient mass transfer coral reef communities
2014/5/8
We dissolved plaster forms in seawater to examine the effects of surface roughness and flow conditions on masstransfer rates. Plaster blocks with varying roughness were dissolved under both steady and...
Dissolution mortality of juvenile bivalves in coastal marine deposits
Dissolution mortality juvenile bivalves coastal marine deposits
2014/5/14
We evaluate experimentally the effect of carbonate saturation state at the sediment-water interface (SWI) on survivorship of various size classes of the juvenile bivalve Mercenaria mercenaria. Populat...
The balance between silica production and silica dissolution in the sea: Insights from Monterey Bay, California applied to the global data set
silica production silica dissolution in the sea Insights Monterey Bay, California applied global data set
2014/5/21
Silicon isotope tracers were used to examine the relative magnitude of silica dissolution and silica production in the Monterey Bay, California, upwelling system. A diatom bloom dominated by Skeletone...
Diminished efficiency in the oceanic silica pump caused by bacterially-mediated silica dissolution
Diminished efficiency oceanic silica pump bacterially-mediated silica dissolution
2014/5/21
Previous laboratory findings indicated that marine bacteria accelerate biogenic silica (bSiO2) dissolution rates in the sea by degrading the organic coating surrounding diatom frustules and exposing t...
Dissolution from a liquid CO2 lake disposed in the deep ocean
Dissolution liquid CO2 lake disposed deep ocean
2014/5/20
The dissolution from a liquid CO2 lake source located at a flat ocean bottom at 3,000 m depth is investigated. Using the unsteady, two-dimensional advection-diffusion equation, temporal and spatial di...
Dissolution of particle-reactive radionuclides in deposit-feeder digestive fluids
particle-reactive radionuclides deposit-feeder digestive fluids
2014/5/26
Naturally occurring radionuclides such as 234Th, 7Be, and 210Pb are important tracers for quantifying sedimentmixing and sediment-accumulation rates. Profiles of these radionuclides in marine sediment...

Acid Dissolution Activation Energy Frequency Factor Hematite Iron Oxide Metal Substitution
2011/12/2
Abstract: The dissolution in 1 M HCl of Al-, Mn-, and Ni-substituted hematites and the influence of metal substitution on dissolution rate and kinetics of dissolution were investigated. The inhomogene...
Gypsum dissolution is not a universal integrator of "water motion"
