# Benthic abundance and composition

Benthos and substrate: With benthos is mend the living organism on the sea bottom (e.g. Coral, seagrass, algae), often it also include the substrate that are considered non living (e.g. Rock, rubble, sand, long time dead coral or reef matrix). The abundance describe the amount of benthic and substrate cover types or on the seabed. Where the composition describes the combination of these different bottom types at a predefined surface area.

With benthic field data collection the composition and abundance of the features that are making up the bottom is determined.
