Significant contribution of passively sinking copepods to the downward export flux in Arctic waters
Significant contribution passively sinking copepods downward export flux Arctic waters
2014/4/17
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...
Sedimentation of acantharian cysts in the Iceland Basin: Strontium as a ballast for deep ocean particle flux, and implications for acantharian reproductive strategies
acantharian cysts a ballast for deep ocean particl
2014/4/16
Acantharian cysts were discovered in sediment trap samples from spring 2007 at 2000 m in the Iceland Basin.
Although these single-celled organisms contribute to particulate organic matter flux in the...
Intermittent oxygen flux from the interior into the bottom boundary of lakes as observed by eddy correlation
Intermittent oxygen flux observed
2014/4/21
Turbulent oxygen transport from the overlying stratified water column into the bottom boundary layer (BBL)
on the slope of a medium-sized lake was investigated using the eddy correlation (EC) techniq...
Eddy correlation flux measurements: The sediment surface area that contributes to the flux
Eddy correlation flux measurements sediment surface area contributes to the flux
2014/4/22
We investigated the size and shape of the area on the sediment surface, the so-called footprint, that contributes to the flux in subaqueous eddy correlation measurements. Tracer tracking simulations w...
Effect of the brittle star Amphiura filiformis (Amphiuridae, Echinodermata) on oxygen flux into the sediment
brittle star Amphiura filiformis oxygen flux sediment
2014/5/21
O2 plays a key role in early sedimentary diagenetic processes, but the effect of most macrofaunal species on the pathways and rates of supply of O2 into the seabed are not well known. We investigated ...
Does 234Th/238U disequilibrium provide an accurate record of the export flux of particulate organic carbon from the upper ocean?
234Th/238U disequilibrium provide accurate record particulate organic carbon the upper ocean
2014/5/20
The magnitude of the flux of biogenic particulate organic carbon (POC) exported from the surface waters of the world ocean and remineralized at depth is critical to constraining models of the global c...
Effects of groundwater flux on open-channel estimates of stream metabolism
groundwater flux open-channel estimates stream metabolism
2014/5/26
The open-channel oxygen method can produce precise estimates of photosynthesis (P) and respiration (R) over a wide range of stream conditions. It is widely recognized that flux of groundwater contribu...
