FRV Scotia 1619S
|Ship name (ship code)||FRV Scotia (748S)|
|Cruise period||2019-10-26 — 2019-11-01|
|Port of departure||Aberdeen, United Kingdom|
|Port of return||Aberdeen, United Kingdom|
1. To recover the time lapse cameras used to assess the macro benthic ecology of drill cuttings around the Murchison oil field.
2. To deploy an acoustic mooring at approximately 60 NM east of Arbroath (JOMOPANS).
3. To undertake grab sampling to assess carbon content on the sediment samples captured.
MRV Scotia will depart from Aberdeen Harbour at 09:00 hours on 26th October (LW, 06:27) and, after all safety drills have been undertaken, make passage to the decommissioned Murchison platform. The completion of the survey work will be heavily dependent on the prevailing weather conditions encountered and a daily plan will be agreed between the SIC, Captain and Fishing Master. The survey techniques are no different to previous similar surveys conducted by MSS using MRV Scotia.
Time Lapse Camera: Six time lapse cameras deployed during 0619S in April 2019 will be collected from the seabed. One of the seven initially deployed cameras has already been collected.
Acoustic mooring deployment: An acoustic mooring will be deployed approximately 60 NM due east of Arbroath. This mooring is composed of an anchoring chain, an acoustic release device for its retrieval and two sound recording devices.
Grab Samples: Grab samples of surface sediments will be collected to be sampled for carbon content. Grabs will be taken at regular intervals during steaming activity to assess the changes in sediment carbon content in relation to distance from land.
A cluster of grabs will be done in the Firth of Forth area if time allows.
Hydrographic sampling: Surface water parameters will be monitored and recorded constantly with the ship's thermosalinograph. Water samples will be taken from the same locations where grab sampling will be done.
