The Daily Update this evening is going to be fairly short and,  sadly,  without any pictures due to a bit of a hectic day.  I will try and get some pictures for the next update tomorrow.

However I have been asked a question about tracking the ship.  There are a number of websites available that it is possible to see where the ship is,  but all have different ways of showing the data and also some tend to lag behind others.  The main method,  and only one that will work regardless of where we are working,  is to find a site that searches out the regular weather observations that the JCR makes every day.  The standard Obs are sent at what is known as the 'synoptic hour',  which is 00:00, 06:00, 12:00 and 18:00 UTC.  This means that the Obs are sent at the same time daily,  regardless of the time zone the ship is working to.  The JCR is currently three hours behind UTC and so this means that the Deck Officers make the observations at 21:00,  03:00, 09:00 and 15:00 local time.  In addition to this the ship is also fitted with an Automatic Weather Station (AWS) that sends pressure and temperature data,  along with position,  every hour.  For a number of years this was available via the link on this website to Sailwx.inf but this has stopped working.  I am not sure why as the data is available and can be found HERE at a French website.

Another way is to use one of the many AIS (Automatic Identification System) websites.  The drawback with this is that the AIS uses VHF for the transmission of data and this has a very limited range,  perhaps twenty or thirty miles,  and so when we are deep sea or in Antarctica the data can't be found.

It was thought that the weather was going to deteriorate during the day but I am pleased to say that has not been the case.  There has been a little motion but that is to be expected.  One thing that is rather surprising is the depth of water here in the Atlantic.  This morning it was about 21m (which meant if we sank on an even keel the chances are we would all be able to hang on to the top of the mast to await rescue!) and looking at the echo-sounder just now it has only got to about 50m.

With only the ship's company and one IT support person on board,  the ship is very quiet in the evening and when wandering through the labs they are deserted,  not a very common occurrence.
