RV Cefas Endeavour 22/13
|Ship name (ship code)||RV Cefas Endeavour (74E9)|
|Cruise period||2013-11-04 — 2013-11-11|
|Port of departure||Lowestoft, United Kingdom|
|Port of return||Lowestoft, United Kingdom|
|Objectives||This survey is part of a 3 week investigation at the North Norfolk Sandbanks and Saturn Reef SCI. During the first week (Survey 22/13) there is the additional aim to build the knowledge of JNCC staff on how to undertake survey work.
1. The aim on this survey is to train a number of participating JNCC survey staff in order that they are able to lead offshore surveys for JNCC in the future. The training element of the cruise will be led by JNCC staff, with support from the Cefas staff in certain instances, such as TOWER training or taxonomic identification.
2. The aim of this survey is to gather additional seabed data to assist with the development of management advice. Objectives can be broken down in terms of priority:
a. Survey areas of existing known Sabellaria spinulosa reef or areas where it has previously been found in order to better delineate the Annex I feature and characterise associated fauna;
b. Survey areas where Sabellaria spinulosa reef is predicted to occur based on observations from (a) in order to better delineate the Annex I feature and characterise associated fauna; and
c. Survey areas of sandbank to characterise distribution of infauna communities in order to better understand sensitivities to demersal fishing pressures.
RV Cefas Endeavour will be mobilised in Lowestoft on Friday 1st, Saturday 2nd and Sunday 3rd November 2013. The vessel will set sail on the morning tide (09:45) on Monday 4th November 2013. The vessel will set sail to the NNS&SR survey area and in agreement with the vessel's captain a detailed operational plan will be developed. A suite of survey tools will be deployed in order to best meet the requirements of the site. It is likely that acoustic survey tools (multibeam echosounder and sidescan sonar) will be used to characterise seabed habitats. In addition, a combination of camera and grabbing work will be undertaken.
Although work is expected to take place across the entire NNS&SR site, additional survey effort will be targeted in those areas where Sabellaria spinulosa was previously found. Survey tools used in these areas will again include: multibeam echosounder, sidescan sonar, grab sampling and video observations.
