Halley Station, being so far south and so remote, relies heavily on RRS Ernest Shackleton for supplies. Each year there are typically two ship calls: at the start and at the end of the season.
RRS Ernest Shackleton departing Cape Town. To the port side, a pilot boat follows, providing assistance.
Life is simple from now on. The blue and white ship in the centre of the frame is the German polar ship, Polarstern.
A couple of days into the cruise, it has become noticeably cooler and the weather started picking up.
A few days into our journey, we were accompanied by a number of sea birds - petrels and albatrosses of all kinds.
These birds measure about 85cm in length and have a wingspan of up to 2m. They nest on various islands in the southern Atlantic Ocean and Indian Ocean.
In late afternoon, deck officers discuss their tactics for getting through the first sea ice. The depth below the Shackleton's keel is over 4400m.

The extent of sea ice this summer season is again larger than usual. The first ice floes were encountered just north of the average August sea ice extent line.
Under a watchful eye of the Chief Officer, the RRS Ernest Shackleton is making its way South towards Antarctica. Ice floes can be seen forward of the ship, and the ice coverage is increasing.

It was an incredibly quiet and peaceful evening, with next to no wind. The only disturbance to the peace was caused by the RRS Ernest Shackleton, making a steady progress on its journey South to deliver the cargo and personnel to the Halley Station.
