Abstract:
The survey was carried out in an area approx. 15km to the east of Harwich. 72 Hammon grab (0.2m2) samples from 24 stations were collected in total - at 12 stations a single grab was taken and at the other 12 stations 5 grabs were taken. 200 taxa in 12 phyla were identified, (85% to species level). Survey was carried out by Unicomarine Ltd for Oakwood Environmental Consultants.
Purpose:
The survey was carried out as part of a marine aggregate dredging application.
NB. Exact date of each survey was not known - date of Sept. 17th 1995 has been used for all 24 sites.
Most of the data collected was quantitative so has been recorded as quantitative (nos per area) under species data type, although presence/absence was used for some colony forming fauna e.g. hydroids and bryozoans.
Further information is available in the report regarding individual species found at each grab however only the average number of species from each site has been entered as the report does not make it clear which results came from each site. Information on sediment particle size for each grab sample is also available
