This update sees me about half-way through my current work period.  Upon my return to Birkenhead,  some five weeks after the end of my last work period,  and on my first walk across to the RRS Sir David Attenborough it was good to see the changes that had taken place.

If one were to visit the ship on a daily basis,  the changes would be hard to detect.  However in the time I was at home,  cabling was being run throughout the vessel and the cabins for both crew and scientists were starting to take shape.  With some good,  and rather unseasonable weather,  it meant that external painting was able to be carried out.

This is the 'Coffee Shop' adjacent to the Mess,  sadly when I visited there was no coffee available!  However this space is being fitted out, along with many others,  and before long all signs of steel bulkheads,  lagging,  pipe work and cabling will all be nicely hidden away and this will be a space to be enjoyed and relax in.

One of the two mighty rudders that will steer the SDA through polar waters.  Attached to these,  and other sections of the ship,  are sacrificial anodes,  which are designed to corrode as they are a highly active metal.  These are then replaced during refit periods but in doing so provides excellent protection to the hull of the ship.

The bottom of the ship has a large array of acoustic devices.  These are mounted in special 'tanks' and depending on the type of transducer may have a titanium cover,  as seen here,  or a polycarbonate cover.  The acoustic pings are transmitted through these and with sound travelling through water at about 1500m per second,  it is possible to do a range of tasks,  from just determining where the sea bed is (whether that be six or six thousand metres),  to actually mapping vast areas of the seabed and even to finding wildlife such as fish and krill.

I am not anticipating another update until my next work period,  in May.  However,  I will from time to time post updates via my Twitter feed which can be viewed below - without the need for a Twitter account.
