Group F Bristleworm Mediomastus fragilis, nemertea and tubeworm Pomatoceros lamarcki; and
Group G Mussels 11.
Group A species roughly match the characterising species from the Zone surveys which cover eastern end of the cable corridor (the majority of which are Group J ‐ N. cirrosa, S. bombyx and nemerteans). Comparisons between the distribution of abundance and taxonomic richness across the cable corridor indicate that the offshore cable corridor has a low overall diversity when compared to East Anglia THREE and East Anglia FOUR.
12.
Overall, the infaunal groups described for the site and cable corridor are what would be expected for the substrate type, i.e. coarse sand and gravel (Figure 1 below) supporting low diversity and low abundances. The survey results are a good fit with previous studies (Heip and Craeymeersch 1995, the East Coast Regional Environmental Characterisation (REC) (Limpenny et al, 2011) and habitat groups identified by UKSeaMap 2010 (JNCC, 2013).
3.2.2 Intertidal 13.
Intertidal habitat at the landfall is predominantly shingle, which runs from the mid to low shoreline. At the southern end of the landfall site the shingle runs into larger cobbles and rock higher up the shore. At the landfall the shingle is unvegetated, with vegetated shingle approximately 300m from where the cables will come ashore.
