The RRS James Clark Ross is on science cruise JR16006 to the Arctic and during this work period will be spending some time outside of the communications satellite that I use to update this web page. More information on this can be found HERE
No sooner had I written the last update when land could be seen outside my window. This proved to be handy as it meant a mobile phone and data signal for many on board and with the recent changes in overseas roaming it meant no additional costs. Sadly land has fallen away once again and we are just a little bit too far away to enjoy the benefits of mobile phone coverage.
On a communications related matter the James Clark Ross altered course this afternoon from a northerly to a north-easterly (I think that the heading required is about 025º in order to keep the coast of Norway where it should be, and this just so happens to be the reciprocal course for the V-sat system which means that if we were to stay on it we would have no communications as the Main Mast is blocking the view of the satellite (with an elevation of about 15º just now). This dilemma has been averted by steering slightly off course, to port and starboard, and so we are now tacking in the direction required. This heading will be required for several hundred miles, so this is the best solution to keeping the communications working. It is not unusual for this to happen from time to time.
A gannet, or booby, keeping a very sharp eye out for it's next meal. Unusually this bird was following the ship, normally they are ahead of us looking for fish being disturbed. As you can see we have had some nice clear sky with sunshine, although we have had a few rain showers during the morning.
I have been out an about in the machinery spaces today, testing the fire alarm system, and had my camera to hand. Here Glyn, one of our Motormen, is giving one of the main engines an injection!
One of the detectors that I tested is up the funnel and this is the view looking down, with Glyn reflecting nicely in the flash of the camera. It is possible to go from the Engine Room right up to the top of the Funnel, above the Monkey Island, although that involves a lot of vertical ladders.
This is one of three seismic compressors that are on board the James Clark Ross and used for seismic survey work, powering air-guns.
A large motor that drives an equally large pump. According to the label it has something to do with fresh water....I think! There are a lot of pumps of varying sizes throughout the ship and all are covered by a planned maintenance system that ensures that they work as well as they should, even after twenty seven years of service.
With the Arctic Circle fast approaching I thought I would finish this evening's update with some information about it:
The Arctic Circle is the most northerly of the abstract five major
circles of latitude as shown on maps of the Earth. It marks the
northernmost point at which the noon sun is just visible on the
northern winter solstice and the southernmost point at which the
midnight sun is just visible on the northern summer solstice. The
region north of this circle is known as the Arctic, and the zone
just to the south is called the Northern Temperate Zone. North of
the Arctic Circle, the sun is above the horizon for twenty-four
continuous hours at least once per year (and therefore visible at
midnight) and below the horizon for twenty-four continuous hours at
least once per year (and therefore not visible at noon); this is
also true within the equivalent polar circle in the Southern
Hemisphere, the Antarctic Circle.
The position of the Arctic Circle is not fixed; as of 1 July 2017,
it runs 66°33'46.7 north of the Equator.
