Bathyal zone, marine ecologic realm extending down from the edge of the continental shelf to the depth at which the water temperature is 4° C (39° F). Both of these limits are variable, but the bathyal zone is generally described as lying between and 2, m ( and 6, feet) below the.

The diversity of bathyal and abyssal marine organisms is still poorly known and this is especially true for tubicolous polychaetes of the family Serpulidae, the common inhabitants of subtidal and shelf locations. We report herein new records of poorly Bathyal and abyssal polychaetes book deep-sea (mostly below m) serpulids collected in the Pacific Ocean by early Soviet Cited by: A.

89 pp. [Determination Key to polychaetes and presentation of Swedish families of. Journals & Books; Help As this is the first collation of abyssal polychaetes, the records were analysed to determine whether there is a distinct hadal fauna and whether the fauna of individual trenches was distinctive or a subset of the abyssal plain fauna.

dispersal from abyssal and bathyal assemblages (Rex et al., ). However, when Cited by: Barry Wilson, in The Biogeography of the Australian North West Shelf, Continental Slope (Bathyal) The slope, terraces, and plateaux from depths of to m are referred to as the bathyal or deep-sea zone.

The bathyal zone and the abyssal and hadal zones below it are referred to as the deep sea. In much of the hydrocarbon resource area of the North West Shelf, the sea bed lies in.

12 species, seven inhabit the bathyal zone and five the abyssal and ultra-abyssal zones. However, the endemic bathyal species are known, as a rule, from a single sample, whereas the deep-ocean species are distributed more widely in 'their own' ocean.

For instance, the most deep-ocean ultra-abyssal and endemic of the Pacific Ocean. Continental Slope (Bathyal) The slope, terraces, and plateaux from depths of to m are referred to as the bathyal or deep-sea zone.

The bathyal zone and the abyssal and hadal zones below it are referred to as the deep sea. In much of the hydrocarbon resource area of the North West Shelf, the sea bed lies in this depth zone.

Forty-nine beam trawl samples were collected from 13 sites. These trawl samples were conducted at both lower bathyal (~ m) and abyssal depths (~ m). A total of about polychaetes from 24 families were recorded, with Ampharetidae, Maldanidae and Onuphidae being the most abundant polychaete families.

The general patterns are similar for bivalves, gastropods and polychaetes, with the highest species numbers per depth interval on the shelf, constantly dropping species numbers on the upper slope (roughly around m) and then more or less constant species numbers at bathyal and abyssal.

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): A total of species representing 17 families of er-rant polychaetes were obtained from 40 bathyal and 43 abyssal stations by the Galathea Expedition Sixteen species were found only in the abys-sal zone, 54 only in the bathyal zone, and 35 in both.

Two species are pelagic. Areas of the Northwest (NW) Pacific have been investigated in the last century from board of the Russian RV Vityaz. During the past decade intensive c. A biofacies dominated by N. umbonifera characterized the lower abyssal zone throughout the Oligocene, and expanded to lower bathyal depths in the South Atlantic during two time periods, ~32–29 Ma and ~24–22 Ma.

These expansions correspond to marine isotope zones Oi2 and Mi1, indicating that there was a faunal response to increased Southern. Abyssal polychaete assemblages from three sites in the NE Atlantic were compared with three from the equatorial Pacific. Both sets of sites lie along perceived productivity gradients.

Abundance of polychaetes was related to measures and proxies of nutrients reaching the deep-sea floor, while diversity was not consistent. The abyssal zone or abyssopelagic zone is a layer of the pelagic zone of the ocean.

"Abyss" derives from the Greek word ἄβυσσος, meaning bottomless. At depths of 3, to 6, metres (9, to 19, ft), this zone remains in perpetual darkness.

It alone makes up. Two bathyal and two abyssal lineages showed a widespread distribution, while five other abyssal lineages each seemed to be restricted to a single ocean basin.

The observed higher diversity in the abyss compared to the bathyal zone stands in contrast to the depth-differentiation hypothesis. Deep Benthic Zones - Bathyal, Abyssal, Hadal The continental slopes are usually called Bathyal zones, usually in the range of m; The general ocean bottom or abyssal plain is the Abyssal zone (m; average m deep, and covering perhaps half of the entire planet).
