Abundance and bathymetric distribution of Bahrain (Arabian Gulf) reef ichthyofaunas

Estuarine, Coastal and Shelf Science, 1987
Abstract Species composition and relative abundance of reef-fish assemblages at 4–7, 7–10, and 13–15 m depths off Bahrain (Arabian Gulf) were surveyed using SCUBA and the species/time, random count technique. A total of 55 species within 22 families was recorded from all reef stations.

Depth distribution and bathymetric classification of some sea-floor profiles

Marine Geology, 1965
Abstract Fifteen east Pacific sea-floor profiles of 60 nautical miles length are analysed as to depth of the sea floor and the character of the hills. Mechanical energies of formation of some model hills are discussed. Several profiles have a Gaussian distribution of depths and others seem to have a large component that is Gaussian.

Change of Bathymetric Distribution of Genus Cyclammina: ABSTRACT

AAPG Bulletin, 1970
Disparities between ancient and modern occurrences of Cyclammina spp., both in abundance and in the nature of the associated fauna, indicate that the bathymetric distribution of the genus Cyclammina in the Gulf of Mexico has changed with time. An examination of Gulf Coast fossil assemblages reveals that this distribution became more restricted during ...

Bathymetric distribution of chironomid larvae (Diptera: Chironomidae) in Lake Saiko, Japan

Lakes & Reservoirs: Science, Policy and Management for Sustainable Use, 2012
AbstractThe distribution of benthic macroinvertebrate on 8 March 2009 was studied in Lake Saiko (73.2 m maximum depth). The average density of the benthic community for the entire lake was 19 583 individuals m−2, being comprised of oligochaetes and chironomid larvae, with densities of 18 163 (92.8%) and 1274 (6.5%), respectively.

Bathymetric Distribution of Brittlestars (Ophiuroidea) Collected off the Northern Oregon Coast

Journal of the Fisheries Research Board of Canada, 1965
A cooperative study by the Bureau of Commercial Fisheries and the U. S. Atomic Energy Commission was undertaken to evaluate the composition of benthic fauna indigenous to waters adjacent to the Columbia River mouth. Standard stations were established by 25-fath intervals between 50 and 500 fath, and by 50-fath intervals from 500 to 1050 fath.

Microplankton of the Gulf of Elat: Aspects of seasonal and bathymetric distribution

Marine Biology, 1977
The components of 4 major groups of microplankton were identified and their numerical abundance determined in net samples collected at depth intervals down to 600 m at a permanent station off the H. Steinitz Marine Biological Laboratory, Elat. The samples analyzed were collected once a fortnight over a period of 1 year beginning in June 1974.

The geographical and bathymetrical distribution of the Fecampiidae (Turbellaria, Rhabdocoela)

Hydrobiologia, 1981
All members of the Fecampiidae are endoparasites. Since 1964 when only four species were known, four new species and 11 cocoon types, made by as many unknown species, have been described. The Fecampiidae are distributed in all major oceans from shallow waters to more than 5000 m depth.

Bathymetric species-diversity patterns and boundary constraints on vertical range distributions

Deep Sea Research Part II: Topical Studies in Oceanography, 1998
Abstract A system where a set of species is randomly distributed within two spatial boundaries produces parabolic species diversity patterns, where diversity is lowest in the vicinity of the boundaries, and highest in the mid-zone between the boundaries. We demonstrate this phenomenon using simulated data. We tested whether parabolic depth trends in

A featureless approach to efficient bathymetric SLAM using distributed particle mapping

Journal of Field Robotics, 2010
AbstractThis paper presents an approach to simultaneous localization and mapping (SLAM) suitable for efficient bathymetric mapping that does not require explicit identification, tracking, or association of seafloor features. This is accomplished using a Rao–Blackwellized particle filter, in which each particle maintains a hypothesis of the current ...
