During the early hours of Sunday morning the James Clark Ross carried out a swath bathymetry survey of the Grattan Seamount,  the location of the science project that is being carried out by National Geographic and the British Antarctic Survey.  As dawn approached the ship made a rendezvous with the fishing vessel Extractor with the intention of carrying out a boat transfer and putting some of the team from JCR to the fishing vessel.  Sadly there was a swell running and it was not safe to carry out the transfer so the plans were modified,  something that happens often on a science cruise,  and when the sea settles down we will try once again.

The F/V Extractor at first light this morning.  It is from St Helena,  some 700 miles or so from Ascension Island and I am told it is an excellent fishing boat.  It is about 22m in length.

It has been another lovely day with a fairly clear sky and lots of sunshine.  This is the view looking aft from the Navigation Bridge Deck across the top of the aft crane.

The Compass binnacle on the Monkey Island.  The ship has three compasses,  two are gyros and are the main ones used for navigating the ship around the oceans.  The one within this binnacle is the magnetic compass and is for emergency use as it requires no power to work.  It is checked on a regular basis and can be viewed from the Bridge via a periscope and mirrors.  All very simple but effective.

This view of the Monkey Island is of the Dartcom satellite receiver,  housed within the dome.  There is just enough room to climb inside,  with the dish switched off,  to carry out maintenance work as and when required and when in Antarctic waters is a nice warm place due to the heaters inside.  Here in the Tropics it will be a bit on the warm side,  and having just looked at the digital thermometer it is showing 35C.

I don't often feel seasick on the James Clark Ross but have to admit to feeling a bit queasy this evening as I was watching the Extractor bobbing about like a cork.  Sea conditions are,  for us at any rate,  very comfortable with a moderate sea,  but on the Extractor it is a very different situation.  I have no idea how they manage to sleep over there but like everything I suspect that they just get used to it.
