Arctic upper bathyal mud

Deep-sea mud sediments have a diverse infaunal community dominated by polychaetes. Epifauna tend to be sparse, mobile species, but aggregations of erect fauna such as glass sponges, sea pens and soft corals can occur.$$$In the absence of ecological data, mud habitat can be defined according to Long (2006), which describes the classifications broad sediment types according to the relative proportion of mud, sand and gravel (see http://www.emodnet-seabedhabitats.eu/PDF/GMHM3_Detailed_explanation_of_seabed_sediment_classification.pdf). Note that Folk muddy sand sediments are classed as mud habitat if the mud content is great enough to support species usually associated with mud. In the absence of particle size data it can be difficult to reliably distinguish between mud and sand.
