For partially-developed structures most bed load particles moved through saltation but a portion of sediment moved in sliding and rolling.
A portion of the impounded sediment was removed by mechanical means during the deconstruction of the structure.
The 3.35-m-high timber crib/rock fill spillway of the Anaconda Dam partially breached during a storm prior to the dam's scheduled removal allowing a portion of the impounded sediment to move down through the river system.
Holes were then sealed with a portion of the extracted sediment core.
A portion of the resuspended sediment was deposited on carbon-coated Formvar films, stained with 2% uranyl acetate and examined in a JEM 100C (Joel LTD, Tokyo, Japan) transmission electron microscope at 80 kV with magnification of ×66,000.
A portion of the resuspended sediment was deposited on carbon-coated Formvar films, stained with 1% uranyl acetate for 30 s, and examined in a Philips CM 100 (Philips CM 100, Japan) transmission electron microscope at 80 kV with 39,000x magnification.
A significant portion of sediment oxygen uptake is not caused by aerobic respiration, but is rather due to reoxidation of reduced inorganic metabolites (e.g., NH4+, Mn2+, Fe2+ and H2S) close to the oxic/anoxic interface.
Because the Japan Trench accretes a large portion of sediment at the toe (Figure 7; Kodaira et al. 2012; Nakamura et al. 2013), sediment variations of 600 m may still affect prism morphology because they are a large percentage of the total sediment thickness.
A few investigations have highlighted that anaerobic N2 production may occur within the Arctic sea ice or snowpacks [18, 57], but the documented N2 production from Arctic sea ice represents only a small portion of sediment yields over the Chukchi Shelf [18].
Remarkably, at later stages of spermatid maturation (P28 and P40), while DCP1a stays concentrated in RNP fractions, a portion of HuR and MVH sediments into denser regions of the gradients (Figure 4C), suggesting that a fraction of these two RNA binding proteins leaves the CB and associates with polysomes while differentiation proceeds.
