Sed rate (erythrocyte sedimentation rate)

Sed rate, or erythrocyte sedimentation rate (ESR), is a blood test that can reveal inflammatory activity in your body. A sed rate test isn't a stand-alone diagnostic tool, but it can help your doctor diagnose or monitor the progress of an inflammatory disease. When your blood is placed in a tall, thin tube, red blood cells (erythrocytes ...

Oceanic sediment accumulation rates predicted via machine

Observed vertical sediment accumulation rates (n = 1031) were gathered from ~ 55 years of peer reviewed literature. Original methods of rate calculation include long-term isotope geochronology (14C, 210Pb, and 137Cs), pollen analysis, horizon markers, and box coring. These observations are used to create a database of global, …

Strong local, not global, controls on marine pyrite sulfur isotopes

Swings of ~65‰ in shelf δ 34 S pyr track short-term variations in local sedimentation and are completely absent from the abyssal record. In contrast, a long-term ~30‰ decrease in abyssal δ 34 S pyr reflects regional changes in ocean circulation and/or sustained pyrite formation. These results highlight strong local controls on δ 34 S pyr ...

Sedimentation rate control on diagenesis, East China Sea sediments

These cores have two common characteristics: shallow water depths (40–70 m) and high sedimentation rate (2–6 mm/year), but the SSB occurs at different depths from site to site ( Table 2 and Fig. 6 ). Hesse and Stolz (1999) pointed out that magnetic mineral diagenesis is mainly controlled by TOC and sedimentation rate.
