MRV Scotia: Survey 1715S Programme

November 24, 2015 by No Comments | Category Compliance, Marine Directorate general, Marine Directorate Science, Research Vessel Surveys

Duration: 18 November – 8 December 2015

Fishing Gear:

GOV Trawl (BT137 – Strengthened) and ground gear D.


  1. To participate in the ICES co-ordinated western division demersal trawling survey;
  2. To obtain temperature and salinity data profiles at each trawling position; and
  3. To collect additional biological data in connection with the EU data collection framework (DCF).


Scotia set sail on 18 November and (after all safety drills and shakedown trawl shoot) commenced fishing operations on the stations to the west of Orkney. A half landing will be made around 1 December, into Greenock, to exchange staff. The survey will end in Aberdeen on 8 December with all staff, equipment and fishing gear returning to the Marine Laboratory.


One trawl haul of thirty minutes duration will be made at the positions (approximate) shown on the attached chart and table. Final trawl locations will be decided after SIC consultations with Fishing Master and Captain. For each haul, the Scanmar monitoring system and NOAA bottom contact sensor will be used to observe and record the performance and geometry of the trawl and trawl doors.

Fish Sampling:

All fish will be treated according to current standard research vessel procedures and additional biological data will be collected as determined by EU data regulation 1639/2001 and 1581/2004.

Hydrography Sampling:

CTD casts will be taken at each trawl station. The thermosalinograph will be run continuously to obtain sea surface temperature and salinity throughout the survey area.
