The bathypelagic community of Monterey Canyon
Deep-Sea Research Part II: Topical Studies in Oceanography, 2010We used a quiet, deep-diving remotely operated vehicle (ROV) to conduct oblique, quantitative video transects of the bathypelagic fauna at depths between 1000 and 3500 m at a site over the Monterey Submarine Canyon, in the eastern North Pacific off central California. Fifteen such dives were made over a two-year period.

Particle‐association lifestyle is a phylogenetically conserved trait in bathypelagic prokaryotes [PDF]
Molecular Ecology, 2015 AbstractThe free‐living (FL) and particle‐attached (PA) marine microbial communities have repeatedly been proved to differ in their diversity and composition in the photic ocean and also recently in the bathypelagic ocean at a global scale. However, although high taxonomic ranks exhibit preferences for a PA or FL mode of life, it remains poorly ...

Limnology and Oceanography, 1956
Four different kinds of hydrozoan medusae, two of scyphozoans, and four of siphonophores are recorded from three basins of southern California, largely in depths greater than 4000 feet. The records are based on photographs made with a special underwater camera which is described. These coelenterates show specific distributional patterns which appear to

Parasitism in the bathypelagic fish, Melanostigma pammelas
International Journal for Parasitology, 1975Abstract Three hundred and thirty-seven specimens of the zoarcid fish, Melanostigma pammelas, collected between December, 1950 and December, 1969 from bathypelagic waters off southern California, were examined for their parasites. Incidences of infection were: digentic Trematoda 61%, Myxosporida 39%, larval Nematoda 9%.

Carbon Monoxide Production by a Bathypelagic Siphonophore
Science, 1964A physonectid siphonophore, Nanomia bijuga , associated with a vertically migrating deep scattering layer, has been observed with a gas-filled float at depths in excess of 300 meters in the sea. This implies that gas is secreted and maintained in the pneumatophore against a diffusion gradient of 30 atmospheres or ...

Pigments of meso- and bathypelagic chaetognaths
Marine Biology, 1977Pigments of the meso- and bathypelagic chaetognaths Sagitta macrocephala and Eukrohnia fowleri were studied by chromatographic analysis. Supplementary histological studies were also performed. Fat-soluble properties and absorption spectra of the chaetognath pigments indicated that all pigments were carotenoid, independent of chaetognath species or ...

Large variability of bathypelagic microbial eukaryotic communities across the world’s oceans [PDF]
ISME Journal, 2015 Abstract In this work, we study the diversity of bathypelagic microbial eukaryotes (0.8–20 μm) in the global ocean. Seawater samples from 3000 to 4000 m depth from 27 stations in the Atlantic, Pacific and Indian Oceans were analyzed by pyrosequencing the V4 region of the 18S ribosomal DNA.

The archaebacterial communities in Antarctic bathypelagic sediments
Deep Sea Research Part II: Topical Studies in Oceanography, 2007Abstract 16S ribosomal DNA clone library analysis was performed to assess archaeal diversity within three surficial sediment samples obtained from the bathypelagic zone (depth: 2165–3406 m) of the Weddell Sea, Antarctica. The nearly complete 16S rDNA gene (1440 bp) was obtained for 146 clones and 46 phylotypes were defined.
