Benthic fauna, through their diverse feeding modes and lifestyles, not only are affected by conditions in the sediment environment, but also actively influence sediment textural and geochemical properties, the flow regime of bottom waters   Benthic habitat maps are derived from aerial imagery, underwater photos, acoustic surveys, and data gathered from sediment samples.

The resulting digital map is viewed using geographic information system tools. Policy makers, scientists, and researchers use benthic maps to make informed decisions that help protect the nation’s fragile shallow   Although many benthic organisms tolerate a wide variety of seafloor central Georges Bank, many are restricted to specific habitats.

This paper combines the results of three photographic surveys, conducted between and with multibeam sonar imagery (collected in ), to characterize the variety of substrates within Santa Monica :// The curvilinear relationship between species richness and habitat area (species–area relationship (SAR)) is a fundamental ecological pattern.

The relationship is often viewed from a long‐term perspective across relatively large spatial scales, reflecting a balance between immigration and extinction :// Faunal material was collected during the same cruise from 11 stations located across the Svalbard Bank at depths varying from 40 to m.

A van Veen grab ( m 2 sample area) was used to collect infaunal samples whenever possible from the east and west bank slopes, resulting in 26 samples from seven stations (Fig.

Benthic surveys using a Phantom HD2 remotely operated vehicle (ROV) were conducted during Changes in benthic sedimentary communities in many areas of the northern North Sea in the vicinity of oil and gas fields have been monitored intermittently over the past three decades, in most cases triennially but in some areas annually for short periods.
