Meiofauna of the Venezuela Basin.

Abstract

Study efforts were focused on quantitative determinations of meiofauna (herein defined as benthic metazoans that pass through a sieve with a mesh opening of 0.500 mm and which are retained on a sieve with a mesh opening of 0.044 mm) that occur in three different sedimentary regimes in the Venezuela Basin. The vertical distributions of meiofauna in each sediment were examined to a depth of 10 cm to establish the existence of significant vertical differences in meiofauna densities. Biomass determinations of total meiofauna were made, and a detailed taxonomic study was also made of the Nematoda, the most dominant taxon, the purposes of examining population structure in each sedimentary type. The three sedimentary regimes consisted of a calcareous ooze; a hemipelagic ooze; a turbidite.
