The origin of the time-scale dependence of sedimentation rates is a subject of active research (Sadler and Jerolmack, 2014; Tipper, 2014; Wilkinson, 2015; Tipper, 2016; Schumer et al ...
Sedimentation rate variation across Sphaeroforma species is driven by cell size and density Lastly, we examined whether the variation in cell sedimentation observed across different Sphaeroforma species ( …
Figure 4: Examples of variations in sedimentation rates, showing an abrupt increase since ∼ 5 Myr ago in different settings. The locations of these settings are shown in Fig. 2.
Abstract. Sediment deposition in water reservoirs has major implications for storage capacity, reservoir lifetime, and water quality. Changes in rainfall patterns and …
Sedimentation rates show temporal and lateral variations in the context of climate changes, and regional tectonics. Exceptionally high hemipelagic sedimentation rates within the last 4 kyrs, are linked to the 3.6 ka Minoan and the 1650 AD Kolumbo eruptions that emplaced abundant erodible tephra.
Estimation of average Cenozoic sedimentation rates for the Atlantic, Indian, and Pacific oceans indicates global synchronous fluctuations. ...

A mean delta-plain sedimentation rate of 6.86 kg/m 2 (6 mm/year) has been calculated from field monitoring of a delta area of about 115 km 2 comprising a dense network of canals 39.
Sedimentation rates and sediment burial also affect the behavior and mortality of benthic macrofauna, ... use have generated a physical template that is influenced by present-day land use, climate, and management actions. Variations in these factors across the watershed and over time result in complex landscape processes and …
The estimated sedimentation rates range between 0.9 × 10 −5 and 20.5 × 10 −5 m yr −1, with the highest rates observed for the diatom ooze and clay deposits in Japan Trench. The lowest rates are for the nannofossil clay and ooze from the Southern High of Shatsky Rise in northern Pacific (Sites 1211 and 1212). 5. Discussion5.1.

The erythrocyte sedimentation rate (sedimentation rate, sed rate, or ESR for short) is a commonly performed hematology test that …
VARIATIONS IN SEDIMENT ACCUMULATION RATES AMONG SALT-MARSH AND OYSTER-REEF LANDSCAPES ... (2014) found that intertidal oyster-reefs in patch morphologies can outpace marsh sedimentation rates. If these results can be applied to oyster-reefs adjacent to marshes, it would allow the reef to
This can be equivalent to sedimentation rate (as discussed above) and so we calculated relative variations on sedimentation rates as a function of growth time (Fig. 11). Download : Download high-res image (488KB) Download : Download full …
Sedimentation rates variation in fast-settling mutants is associated with variation in cell size and cellular density.

Compared to the narrow range of sedimentation rate variation (90 to 220 m/Ma) at ODP Site 1247, ODP Site 997 at Blake Ridge (Figure 1), located in Atlantic Ocean off the southeast North American continental margin, has much higher sedimentation rates and a much larger range of variation from 40 to 340 m/Ma during a period of 6 Myr …
