The survey gets us out and about all over the island, to the little nooks and crannies that we don't usually visit. We still have some pretty ice around.
Whilst out and about on the chinstrap survey, it has actually been the Adelies who have been the most photogenic as the chinstraps are just sitting dutifully on their eggs. There is much more activity in the Adelie colonies. The chicks are already suprisingly large!
This pair is almost too big to fit underneath its parent. It is good to see many nests still with two chicks- in a really poor year they can only find enough food to rear one.
Whilst out surveying we came across something quite special. Spot the odd one out!
This Adelie is leucistic, meaning it has a pigment disorder resulting in a partial loss of pigmentation in its feathers. This form of leucism is known as Isabellinism- where the bird has a uniform reduction in the pigment melanin all over, giving it a honey colour everywhere that should be black. It has brownish toenails and an almost red beak. It is not an albino, which would have no colour at all and pale eyes.
It looked perfectly happy with its fellow colony buddies.
Finally to finish, here is some more ice in the bay.
On base we are starting to prepare for Christmas. We put the Christmas tree and decorations up yesterday and my Christmas cakes are maturing, waiting to be iced. The temperatures are hovering around minus two- probably warmer than the UK at present!

The season is moving on- we have been here for almost a quarter of our time already. In another 10 days we'll have reached the longest day here. It doesn't really get dark at night much these days which is rather nice.
The wildlife is also busy progressing through the season. The Adelie penguins now have small chicks.
They are guarding these closely from predators like skuas and giant petrels.
The chinstraps nest about a month later than the Adelies.
They have just finished laying their eggs and now begin the process of incubating them.
We had a nice visitor one day to the beach in front of the station. This little Weddell seal came to visit and seemed very content snoozing on the beach.
Meanwhile, on station things moved on too and we had the second ship visit of the season- the RRS Ernest Shackleton, which called yesterday. It is too big to get to the jetty (so people and cargo are moved in small boats) but it has a shallow draft so can get much closer than our other ship, the James Clark Ross.
The Shackleton brought four new scientists. This bring the number of people on station up to eight, which is the maximum we can fit in. It feels much busier than it did til now as there were only 5 of us for the first part of the season. Claudia, who has been with us from the start but has now finished her science here, left on the ship. She has been collecting small crustaceans from the lakes and shorelines around the island. Here are the original team- Matt, Iain, Me, Catrin and Claudia.
(the orange boilersuits are not compulsary, but they are a firm favourite for wearing around and about- rather like wearing a duvet!)
This will now be the last ship we see until early February when there will be another change of personnel, who will join us for the remainder of the season. The next couple of months will be the busiest- there is much to do!

Happy Antarctica Day!
December 1st is Antarctica Day. This day celebrates the signing of the Antarctic Treaty on 1st December 1959. The Antarctic Treaty, signed by 48 nations is a perfect example of global cooperation between nations, designating the whole of Antarctica as a "natural reserve, devoted to peace and science". The treaty sets aside all claims of territorial ownership by the various nations, and prohibits military activities and mineral extraction. Conventions passed by the treaty nations protect the Antarctic as a whole, enhancing scientific discovery, monitoring the status of the continent and its wildlife (my job) and regulating fishing and tourism to sustainable levels. The treaty has resulted in successful cooperation between all nations, working together for the greater good and is as strong now as when it was first signed.

It seems a shame to me that we can't use this as a model for the rest of the world!
We can't celebrate Antarctica Day without some penguins, so here are a few pictures. The Adelies are currently still incubating and the colonies are clean and tidy with each bird sitting on their nest of pebbles, patiently waiting for their eggs to hatch.
Its a long job, so snoozing is often a good way to pass the time...
Yesterday when I went to visit my study birds, it was exceedingly windy and the birds had all turned themselves round to face the wind. This made them look particularly neat and tidy.
From the front the Adelies look rather intimidating! Not something to be messed with. Especially the one in the middle of the picture!
The first egg was just showing signs of hatching yesterday with a pea-sized hole in the shell and a tiny beak showing through. It will hatch fully today- what better day to arrive into the world than on Antarctica Day!

With the ship gone, it was time to settle in and start work. Within a few days of it leaving, the rest of the boxes were all unpacked and the research station was fully up and running. Everyone settled into their various roles and routines.
My first job was to head across to Gourlay to my penguin colonies there. This is where I do the majority of my monitoring work. It is about an hours walk from the research station. The Adelie penguins were here long before we were, and are already settled on eggs. These should start hatching any day now. For such a noisy bird, the colonies are suprisingly quiet at this stage.
There are a lot of Adelies at Gourlay...
It is important to try and work out what stage in the breeding season they are at, so I can conduct the rest of the seasons counts at the correct stages through the breeding season to enable them to be consistant over the years and therefore contribute to the longterm datasets. Their arrival times can vary by several weeks depending on a range of factors such as the amount of sea ice and the condition of the birds themselves. Once the eggs start to hatch, we will be able to determine when the eggs were laid.
Away from Gourlay, we had a day trip to Northpoint, which is (as expected) the northern most point of the island. This is where the gentoos nest. They were also settled on their eggs.
The Blue-eyed shags also nest at Northpoint. They have spent a lot of time neatly constructing nests and are just starting to lay eggs now. Being able to fly, they have the advantage of a wider choice of nesting materials and often build with seaweed. Their nests look much softer and more comfortable than those of the penguins!
There weren't many chinstraps around when we first arrived as they breed later in the season. The first males were just arriving, to defend their nest sites from rival males and start building a nice pile of pebbles, ready to impress their partners who arrive a few days later.
We have quite a lot of sea ice at present which looks particularly nice on a sunny day.
The sea ice constantly changes. As the wind direction and tides change, the sea ice moves around so every day is different. These penguins were in the bay at Foca Cove, which was full of sea ice when we visited.
Here is Claudia for scale...
We have been quite lucky with the weather so far, enjoying some beautiful sunny days and some lovely snow.

With the air temperature pretty chilly too, the aft deck was covered in ice where the waves had been washing over it and freezing immediately.
The rest of the ship looked like some kind of ghost ship with everything white and ice covered.
It was going to be a cold day for working! The first cargo tender arrived to offload people to start the process of opening up the base for the summer. Jobs to be done were to dig out the walkways and doorways to the buildings, to remove shutters from the windows and to start the process of getting the services up and running. On days like this, everyone, regardless of their reason for being onboard, mucks in to get the job done.
These jobs all take time and have to be done in the right order. Generators have to be warmed up properly before they can be started and buildings need a chance to warm up before things like communications can be switched on. The first day went very well, and by the end of the first day we had heating, lighting and flushing toilets on station meaning we were able to spend the first night ashore in our Signy home.
Day two dawned a complete contrast with glorious blue skies and sunshine.
The digging continued...
This pipe is critical to life at Signy- it brings sea water into the generator shed where it is pumped up to the main building for flushing toilets, or diverted to the Reverse Osmosis plant which converts it to drinking water.
By the end of day two we had started making fresh water, all of the cargo was ashore and being unpacked, and the base was starting to feel much more homely.
The ship finally left us with a fully functional base at the end of day three.
This year there are only 5 of us for the first part of the season, but we are back up to eight people with the next ship call in early December. There is much to do in the next couple of weeks- unpacking all of the cargo that has come ashore, stocking the foodstore, tidying up, and starting the science that allows us to be here in the first place.
It is great to be home!
