Seabed foraging by Antarctic krill Implications for stock assessment bentho-pelagic coupling the vertical transfer of iron
2014/4/8
A compilation of more than 30 studies shows that adult Antarctic krill (Euphausia superba) may frequent benthic habitats year-round, in shelf as well as oceanic waters and throughout their circumpolar...
Effects of bottom shear stresses on the wave-induced dynamic response in a porous seabed: PORO–WSSI (shear) model
Bottom shear stresses Wave-induced dynamic response Porous seabed “u–p&rdquo approximation Biot’s theory
2012/2/28
When ocean waves propagate over the sea floor, dynamic wave pressures and bottom shear stresses exert on the surface of seabed. The bottom shear stresses provide a horizontal loading in the wave-seabe...
