“…Grice (1972), who used plankton nets attached to a submersible and observed a distinct benthopelagic fauna 20Á50 cm above bottom at 1000Á1500 m. All 14 'planktobenthic' Copepoda species in his samples belonged to the families Aetideidae, Phaennidae and Tharybidae.…”

The study presents results on the composition and vertical distribution of the near-bottom plankton community at an abyssal site in the NE Atlantic. Plankton samples were collected at 1, 15, 50 and 100 m above bottom (mab). Whereas the composition within the upper three layers was very similar, a major shift occurred in the immediate vicinity of the seafloor. Between 100 and 15 mab, the plankton was dominated by Copepoda, making up more than 75% of the total abundance and biomass (without gelatinous organisms). At 1 mab, Copepoda were still abundant, but their share decreased to ca. 50%, while Polychaeta, Malacostraca and Chaetognatha became important groups. Within the Copepoda, the predominance of the genus Metridia (Calanoida) in the upper layers was replaced by the genus Benthomisophria (Misophrioida) at 1 mab. Despite enrichment in organic particles towards the bottom, the total abundance and biomass of plankton did not show marked differences between the four layers investigated. Several hypotheses are discussed which may explain why the presumably higher food concentrations near the deep-sea floor do not lead to increased standing stocks of the plankton community.

“…Members of this fauna include medusae (Hartman and Emery 1956;Smith 1982), pelagic holothuroids (Barnes ct al. 1976), cirrate octopods (Roper and Brundage 1972), copepods (Grice 1972; with the statistical analyses. We also thank the Alvin group and the captain and crew of the Lulu for their help.…”

A quantitative plankton net sampler with a multicompartment cod-end for use with deep submersible vehicles was developed. This cod-end protects samples from surface temperatures so that deep-sea animals can be recovered alive. The DSV Alvin used it to sample the benthopelagic faunas forms, a group dominated by copepods and larger crustaceans, were more uniformly distributed and ranged from 2.1 to 7.9 mg wet wt m-3. Abundances of Scotoanassa sp., but not the other categories, varied greatly between years and between basins. Scotoanassa sp. had a low oxygen consumption rate of 0.0009 ~1 O2 (mg wet wt)-' h-l; the near-bottom crustaceans had rates similar to those of bathypelagic crustaceans. Total metabolism of the sampled groups was dominated by Scotoanassa sp. and nongelatinous plankton near the bottom with other gelatinous plankton becoming dominant higher. Scotoanassa sp. may be a rapid growing, opportunistic species that can respond reproductively to short-term environmental changes.
