Production, dissolution, accumulation, and potential export of biogenic silica in a Sargasso Sea mode-water eddy
Production dissolution accumulation
2014/4/16
Rates of biogenic silica (bSiO2) production, dissolution, accumulation, and potential bSiO2 export were
determined in a Sargasso Sea mode-water eddy (MWE) during two occupations in April 2007. Standi...
Death by dissolution: Sediment saturation state as a mortality factor for juvenile bivalves
Sediment saturation state juvenile bivalves
2014/4/18
We show that death by dissolution is an important size-dependent mortality factor for juvenile bivalves.
Utilizing a new experimental design, we were able to replicate saturation states in sediments ...
Phosphorus release with carbonate dissolution coupled to sulfide oxidation in Florida Bay seagrass sediments
Phosphorus release carbonate dissolution
2014/4/17
We hypothesized that CaCO3 dissolution, coupled to sulfide oxidation, is an important mechanism by which
solid-phase inorganic P (iP) becomes available to seagrass in tropical carbonate sediments. To...
Shallow water dissolution of settling calcite at Station ALOHA
settling calcite Station ALOHA
2014/4/17
The dissolution of settling calcite at the Hawaii Ocean Time-Series Sta. ALOHA in the North Pacific is
examined using a calculation of the calcite saturation state based on 5 yr of alkalinity measure...
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 ...
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...

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...
