چکیده

Mesozooplankton abundance and species composition in the upper 200 m at seven sites in Lützow-Holm Bay, Antarctica, were compared using plankton nets with 60, 100 or 330 mm mesh during the austral summer of 2007–2008. While the collection efficiency of the 330 mm mesh was low, ranging from 2.0 to 5.6%, owing to the significant underestimation of small copepod species, no significant underestimation of abundance was found using the 100 mm mesh, except for copepod nauplii.

An Overview of Southern Ocean Zooplankton Data: Abundance, Biomass, Feeding and Functional Relationships

There is an enormous amount of data on Southern Ocean (SO) zooplankton, mostly on their distribution with a minority addressing rate processes. This review aims to summarise these data and show where it resides, to assist SO food-web modellers or those with limited specialist knowledge of SO zooplankton. First, a brief overview is provided of the diversity and basic biology of SO zooplankton, w...

Study on transferred impulse and response of steel plate walls under various impulsive loading considering mesh size effects

The behavior of steel plate walls (SPWs) under various impulsive loadings and the effects of different mesh sizes are investigated in this paper. With the aim of accurately inspecting SPWs, a series of analyses with 250 models with different plate geometric assumptions and different blast impulsive loadings are performed to study the SPWs’ out-of-plane behavior. The mild steel material specific...
