No. 18: CEND23/16X Cruise Report: Monitoring Survey of Pisces Reef Complex cSAC-SCI
(018 - 2017)
Jenkins, C. & Nelson, M.
The monitoring survey at Pisces Reef Complex candidate Special Area of Conservation (cSAC) and Site of Community Importance (SCI) was carried out aboard the RV Cefas Endeavour. The survey team for the duration of the fieldwork included Cefas marine scientists, three marine scientists from the JNCC, two geophysicists, two hydrographers and a PAM operator.
 

Abstract


This report summarises the methods and data acquired during a survey of the Pisces Reef Complex candidate Special Area of Conservation (cSAC) and Site of Community Importance (SCI). The monitoring survey of the Pisces Reef Complex was carried out from 30th October – 4th November 2015, as part of a cruise that also visited Utopia Marine Conservation Zone (MCZ) on behalf of Natural England.

There were two key aims of the survey:

1. Acquire sentinel monitoring data to support the ongoing monitoring time-series for the Pisces Reef Complex.
2. Provide evidence on the structure, function and condition of the Annex I Reefs (both rocky and stony) against which the direction of change can be inferred over time.

A variety of data types were collected during the six-day survey including multibeam echosounder bathymetry and backscatter, chirper sub-bottom profiles, high resolution video and stills, and water samples to calibrate the camera frame mounted CTD. 

Weather conditions were very good throughout the survey period with only minor data artefacts occurring in the sub-bottom data. Video transect locations were selected on vessel using multibeam echosounder and sub-bottom profiler data to target both areas of potentially exposed rocky reef and wider muddy habitat. 391km of multibeam and chirper data were acquired across the three Pisces Reef areas along with 63 video transects and 11 water samples. Due to the good weather, all of the survey objectives were completed with the vessel able to remain on site and work continuously, with no need to make use of the weather contingency sites.
