Sed rate (erythrocyte sedimentation rate) Mayo Clinic . Sed rate, or erythrocyte sedimentation rate (ESR), is a blood test that can reveal inflammatory activity in your body.

Abstract. The abundance and flux of acantharian cysts were recorded for a period of 12 months from December 2012 to 2013 in a sediment trap deployed at 1500
Freedrifting sediment traps were used to derive large particle fluxes between depths of 100 and 3500 meters in the eastern and western North Pacific Ocean. Flux data revealed substantial quantities of acantharian skeletons and cysts (both made of strontium sulfate) settling through the upper kilometer of the water column.
Acantharian cycts have been recovered from sediment traps and their concentrations decrease sharply with depth over the top 1000m mirroring the increase in dissolved Sr in the water. Fig 45 Acantharian skeleton and cyst from Bermuda in the North Atlantic . 8

Acantharian symbionts include dinoflagellates and prymnesiophytes, and some species have more than one symbiont type within the same host. Symbiont abundances vary within a host from a few large dinoflagellates, to many thousands of smaller cells. Most Acantharia have symbionts at some stage in their life cycle (Michaels, 1991).
Seasonal variation of acantharian cyst sedimentation. Longterm sediment trap deployments across a latitudinal gradient allowed us to follow the seasonal dynamics of the acantharian sinking flux. Strontium fluxes in both subtropical and Scotia Sea traps showed a marked seasonal pattern,

Considering the average acantharian Ba content (5 pmoles) and the upper 150 m acantharian abundance (73,700 m −3) we calculate that the acantharian‐associated Ba if entirely transloed into barite and now re‐distributed into the 150–1000 m layer (850 m), could account for 18% of the mesopelagic Ba xs contents.

Acantharian 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 in the upper mesopelagic, their contribution to bathypelagic particle flux has previously been found negligible.

Freedrifting sediment traps deployed at 400, 1500, and 3200 m were used to collect particles near the US JGOFS TimeSeries Station (31䓱.5′N and 64䓈.2′ W) in the Atlantic Ocean. Acantharian specimens isolated from our samples were abundant at the 400m depth horizon and were rare to nonexistent in our 1500m traps.
