These tests focussed on the clayey-silty fillings, encountered as sediments at the cave floor, in karst cavities and fractures.
The Jurassic sediments encountered in the tunnel included breccia and conglomerate in contact with the underlying gneisses and a sandstone with coal fragments, some of which was quite unconsolidated.
where ntot(x) is the mean total number of burrows encountered in the sediment slab, and A0 is the horizontal surface area of the 3D grid.
These muddy sediments were encountered at the base of all other sediment cores from the Gyra fan.
In all other sediment cores from the Gyra fan structure and the adjacent lagoonal area (in transects A and B), these muddy sediments were encountered in a similar stratigraphical position.
No Loricifera were encountered in the oxygenated sediments surrounding the basin, where nematodes and copepods accounted for 95% and 4%, respectively, of the total metazoan abundance.
In alluvial fan sediments, it is expected that finer-grained sediments should be encountered with depth and in distal locations, such that hydraulic conductivity will decrease with depth and distance from the sediment source (Reading 1978; Blair and McPherson 1994); deposition of fluvial sediments on top of alluvial fans could deposit fining upwards sediments on top of the alluvial fan sediments.
Benthic infaunal organisms living in sediments encounter relatively high concentrations of pollutants and may also suffer toxic effects of ENPs.
A well-preserved Eemian sediment record was encountered as the infill of a Late Saalian (MIS6) subglacial basin.
The latter intention caught Wolfgang by surprise, but despite his light colored, long coat, he fetched a van Veen Grab Sampler (which, I believe, still exists), drove us to the Port of Hamburg Harburg, and pointed out where to fetch a "suitable" sample… The man really knew his environment: That was the most evil smelling sediment I have encountered ever since.
