Atlantic abyssal mud
Description (English)
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 classification's broad sediment types according to the relative proportion of mud, sand and gravel (see p3 of UKSeaMap 2010 technical report 3 http://jncc.defra.gov.uk/pdf/UKSeaMap2010_TechnicalReport_3_Substrate2.pdf). It can be difficult to reliably distinguish between mud and sand using video data only. Note that muddy sand sediments are classed as mud if the mud content is great enough.
