Typically, all undecomposed metazoans found in formalin-poisoned cups of sediment traps are considered to be active intruders (or ‘‘swimmers’’) and are removed to prevent an overestimation of the down...
Diatom sinking speeds: Improved predictions and insight from a modified Stokes’ law
mproved predictions insight
2014/4/17
Accurately predicting the size-dependant sinking rate of diatoms is necessary to fully understand the cycling of
oceanic carbon and silicon. Stokes’ law predicts that sinking velocity should be propo...

2010/1/19
The flux of materials to the deep sea is dominated by larger, organic-rich particles with sinking rates varying between a few meters and several hundred meters per day. Mineral ballast may regulate th...
Intense cooling of a warm-core ring or warming of the fluids surrounding a ring can increase the density of that ring relative to the surrounding fluids. This increase in density can cause the ring to...
