Acantharian cysts have been collected in sediment traps and net samples around the world, at high latitudes (Antarctic, East Greenland Sea, Iceland Basin,,, ), Acantharian skeletons are composed of strontium sulfate, SrSO4, in the form of mineral celestine crystal Celestine is named for the delicate blue colour of its crystals, and is the heaviest mineral in the ocean The denseness of their celestite ensures acantharian shells function as mineral ballast, resulting in fast sedimentation to bathypelagic depths High settling fluxes of acantharian cystAcantharea

Abstract/Summary Acantharian cysts were discovered in sediment trap samples from spring 2007 at 2000 m in the Iceland Basin Although these singlecelled organisms Their large size (, 1 mm) and mineral ballast result in a sinking rate of,500 m d21; hence, they reach the bathypelagic before dissolving Our findings are consistent Sedimentation of acantharian cysts in the Iceland Basin CORE

It is hypothesized that Acantharia at high latitudes use rapid, deep sedimentation of reproductive cysts during phytoplankton blooms so that juveniles can exploit the large quantity of organic matter that sinks rapidly to the deep sea following a bloom Acantharian cysts were discovered in sediment trap samples from spring 2007 at 2000 m in the Sedimentation of acantharian cysts in the Iceland Basin: Strontium as a ballast for deep ocean particle flux, and implications for acantharian reproductive strategies Patrick Martin,a,* John T Allen,a Matthew J Cooper,a David G Johns,b Richard S Lampitt,a Richard Sanders,a and Damon A H TeagleaMartin, Patrick, et al Sedimentation of acantharian cysts in the

Sedimentation is of vital concern in the conservation, development, and utilization of our soil water resources 泥沙淤积问题是水土资源的保持, 开发和利用中最受关心的事 The deposit is formed in marine invasion by weathering crust transportation, sedimentation, diagenesis and super genesis 矿床是在海侵过程中[3,21,25] However, a particularly large type of acantharian cyst was recently found in sediment traps from 2000 m in the Iceland Basin, contributing up to 48% of POC flux during a 2week sampling interval [4] It was hypothesized that deep sedimentation of cysts might be limited to high latitudes and exhibit a seasonalDiversity, Ecology and Biogeochemistry of CystForming

Sedimentation removes settleable solids by gravity The process takes place in sedimentation basins that are either rectangular, square or circular By increasing the volume of the flow channel, the flow velocity is slowed to the point where there is no turbulence and the suspended solids are allowed to settle outAcantharian cysts were discovered in sediment trap samples from spring 2007 at 2000 m in the Iceland Basin Although these singlecelled organisms contribute to particulate organic matter flux inMartin, Patrick, et al Sedimentation of acantharian cysts in the

Similar measurements suggest that acantharian cysts in the subarctic Pacific may also sink to great depths Acantharian cyst flux in the Iceland Basin was restricted to April and May It contributed up to around half the particulate organic matter found in the traps during the two weeks of highest cyst flux, albeit with considerable A sedimentary basin is a depression on the Earth’s crust that provides an accommodation space for sediments A sedimentary basin may not be a depression at present, but in its geological past, it was a low depression, that accommodated sediments from the surrounding regions Therefore, a sedimentary basin refers to an area where Sedimentary Basins SpringerLink

Irrigated agriculture, particularly smallscale irrigation (SSI), is a mainstay for sustainable livelihoods in the developing world In Ethiopia, SSI sustainability is threatened mainly due to excessive sedimentation Stakeholders’ perceptions of the causes of sedimentation and how they sustain SSI under excessive sedimentation conditions A sedimentation basin is 60 ft long by 22 ft wide and has water to a depth of 10 ft If the flow to the basin is 1,500,000 gpd, what is the sedimentation basin detention time? First, determine the volume of the rectangular basin with the formula: Volume = Length, ft x Width, ft x Depth, ft x 748 gal/ft 3Lesson 6: Sedimentation Calculations Mountain Empire
