Summary

Deep-sea corals can create a highly complex, three-dimensional structure that facilitates sediment accumulation and influences adjacent sediment environments through altered hydrodynamic regimes. Infaunal communities adjacent to different coral types, including reef-building scleractinian corals and individual colonies of octocorals, are known to differ from background non-coral soft-sediment communities, often exhibiting higher macrofaunal densities and distinct community structure. However, the coral types have different morphologies, which may modify the adjacent sediment communities in discrete ways. Here we address two main questions: 1) how infaunal communities adjacent to deep-sea corals and their associated sediment geochemistry [...]

Purpose

Data were obtained in order to assess benthic macrofaunal community structure and function, and sediment geochemistry near multiple deep-sea coral habitats in the Gulf of Mexico to inform conservation and management decisions.
