JNCC Offshore Survey Blog

As part of our statutory responsibility to recommend Marine Protected Areas (MPAs) in UK offshore waters (beyond 12 nautical miles), JNCC gathers information to help support these recommendations; either by searching and retrieving existing information, or through collaborative or commissioned survey. Once these MPAs have been identified, further information gathered through survey may be required to deliver management measures and conservation advice. JNCC survey work takes place throughout the year and our staff who join the research vessels will blog throughout the survey sharing information and images from the survey.

  • North East Faroe-Shetland Channel Survey Update

    Welcome to the 2017 monitoring survey by Marine Scotland and JNCC onboard RV Scotia to North-East Faroe-Shetland Channel Nature Conservation Marine Protected Area (NCMPA) (Figure 1) and Wyville Thompson Ridge Site of Community Interest (SCI).

    Figure 1. North-East Faroe-Shetland Channel NCMPA sampling locations, shown as ‘Box A’ (red points), ‘Box B’ (blue points), ‘Box C’ (purple points) and ‘Box D’ (green points).

    The survey is split in to two legs, ten days for the North-East Faroe-Shetland Channel NCMPA and a further ten days on location at Wyville Thompson Ridge SCI. Leaving Aberdeen at 5am on Friday 19thOctober meant that during the 36-hour transit we had time to prepare all of the equipment, familiarise ourselves with the data management processes and standard operating procedures, and get our body clocks into our various shift patterns allowing us work around the clock (Figure 2).

    Figure 2. Familiarisation with (A) the equipment and (B) relevant processes and procedures.
    We arrived at North-East Faroe-Shetland Channel NCMPA at midday on Saturday 21st October. The first shift lasted from midday until midnight using Hamon grabs to collect sediment samples from ~660m for particle size and infaunal analysis and working alongside colleagues from Marine Scotland Science who directed the chariot tow video equipment operations (Figure 3B). The video footage from the chariot tow showed coarse-gravelly sediment prevailing, a variety of sponges (potentially including massive, pedunculate, papillate, and flabellate sponges) and multiple sighting of chimera fish. With the first shift over, all chariot tows within ‘Box A’ were complete (Figure 3).

    As the first night shift began the weather took a turn for the worst, with Storm Brian becoming ever closer. This meant that the nights sampling had to be postponed from midnight to 8am on the 22ndOctober. During this time, the JNCC night shift collated all the metadata from the previous shifts work, backed everything up on multiple hard drives, and ensured all positional information relating to the day’s sampling efforts were stored and correct.

    As the first night shift ended, the weather had calmed down considerably, enabling us to begin chariot tow work in ‘Box B’.
