C.1.1 Univariate Statistical Analysis of the EAOW Cable Route Sediment Data
A total of 41 PSD samples were acquired from across the site. This figure includes the PSD sub-samples taken from benthic samples during the EAOW zonal benthic survey within Area B (Table 1).
All sediment samples were sieved across a range of sieves from 31.5mm to 0.063mm. The results showing the percentages of material retained on each sieve are presented in Appendix Table 4.
The PSD data acquired from the EAOW cable corridor area has been grouped into three broad sediment categories:-
Appendix Table 5 outlines the %gravel, %sand and %silt found at each station across the EAOW cable corridor area.
Figure 4 illustrates the distribution of the percent gravel, sand and silt found across the EAOW cable area from the PSD data acquired during this survey. Sand was the most prominent sediment type found across the area of interest. Some of the sites near to the shore were dominated by either silt or gravel, which may be reflective of the fluvial and coastal processes which influence these areas. Coarser sediments were recorded at many stations; especially those which lay within 10nm of land.
