Race Across Antarctica

After Bird Island's triumph in the Rebel Race last winter we were looking forward to this year's fitness challenge with a degree of trepidation, knowing we had something to live up to and would be without the influential Craig.

This year sees the return of the official race, organised by those in Cambridge with teams from there, the ships and the bases completing a distance of either 2,840km (Scott's Terra Nova route from Cape Evans to the pole and back again), 6,000km (across the continent from Cape Hope to Cape Adare) or a monumental 12,000km (a 'grand tour' that takes in many of the research stations). We've a ten week window to complete our chosen distance and, like most of the 26 teams entering, we will be going for the 6,000km trek.

We've put together our team of six – the four of us on base plus the other two field assistants who have just got back to the UK and are keen to retain their Bird Island fitness in the presence of such mainland luxuries as take-away food.

Activities have been weighted with different scores based around world record speeds, hence 1km cycling = 2.5km running / walking = 3km rowing = 10km swimming. We have machines for all but the latter, which sadly is off the list of events until I get somewhere warmer. With less outdoor work to do and with the nights drawing in we've plenty of time to get moving.

Here's a few pictures of what else has been happening recently:

Wandering Albatross are starting to head off to spend the winter at sea.
The last few unpaired ones are still dancing round like the singles left in a club at 2am.
A possible last opportunity for established pairs to spend time together before spending all their time feeding and bringing back food for their tubby, fluffy chick who will otherwise be left alone for the next six months,
While the Macaroni Penguins have headed out to sea and won't return to land before October, the Gentoos stay closer and often come ashore in large numbers in the evening.
Grey-headed Albatross are continuing to feed their chicks, although it won't be long before they follow the Black-brows in starting to fledge and head off themselves.
As the days get shorter there's more of a chance of being out to see a sunset. Though there won't be many like this, with a clear sky.
Clear skies also mean good opportunities for stargazing.
With the majority of Giant Petrel chicks having fledged the adults gather together to discuss the breeding season. 
Great views across the South Georgia mainland from near the tip of La Roche.
Testing the ice on the frozen ponds.
On a final note, congratulations to my previous workplace Skokholm, on it's official re-opening as a UK BirdObservatory. An amazing amount of hard work and changes have happened there in the last five years.

First Winter Blog


All change at Bird Island

I arrived back on 14th March. Later than planned due to bad weather, but that meant I had a chance to see KEP again, this time in the snow, a lot of which had fallen while I was out feeling rough at sea. There was a decent amount of snow remaining when I got back to Bird Island and I had time to race up the valleys to play in it and appreciate being back while it was sunny and the ship's crew were deciding on a plan of action for last call.

The snowy La Roche and South Georgia from the top of Gazella.
Ruth, Jen, Jon, Tamsin and Iain (who I'd only briefly crossed over with) headed off later that afternoon. A strange and emotional departure; we weren't sure if they'd return the next day or if that was it. To go from living and working so closely with people and then having half of them suddenly leave is a bit daunting, particularly when they know so much about the place and the work.

Our last view of the others as they are shipped off to the RSS Ernest Shackleton  and return to the UK (via a trip down to the peninsula).
They didn't return, just a few of the crew came back in the RIBs to pick up outgoing cargo and waste as well as dropping off a few bits of cargo, fresh veg and what post they had for us.

It's taken a bit of getting used to running the base with just four people – cooking comes around twice as often, there are more cleaning jobs each, the place can easily feel a lot quieter if a few are out working. We've not been able to properly settle into the more relaxed winter regime yet as there's still a lot of work going on:


Penguins / Geeps

The Northern Giant Petrels are fledging, while the Southerns are not too far behind. I'm carrying out weekly rounds to check on them and will soon be out ringing the Southerns and sending a few on their way with tiny GLSs so we can find out where they travel to and feed in those important few juvenile years.

There's not too much penguin work at the moment as all their chicks have fledged. Gentoos are finishing their annual moult spread sparsely around the beaches, while the Macaroni colonies are full as the adults moult before heading out to sea for the winter. We managed to take advantage of a clear evening to head down to the bottom of Big Mac to watch them arriving and departing, riding in on the breaking waves and struggling through the kelp.

Albatrons

Black-browed and Grey-headed Albatross chicks are getting pretty big now, not far off fledging. I've been out helping Steph weigh and ring them. By weighing on specific days after hatching we can study how they progress and how healthy the population as a whole is. It is also very useful data for predicting how future changes to food supply will affect these species.

The Wandering Albatross eggs have hatched and the first chicks are starting to be left unattended, their parents heading off to sea and only returning to feed them. It was the monthly census on 1st April and I headed over to Farewell Point on the east end of the island, checking nests on the way. It was a cold but clear day and I took advantage of this and the early start to head back via the ridge at the top of north cliffs. This tiring and walk and occasional scramble was well worth it, offering some magnificent views across Bird Island and South Georgia. I finished up with my first ascent of La Roche, at 356m the highest point on the island by some distance.

Views along the ridge - steep and spectacular.

Seals

The seal work continues to fill days, with the team of three dropping to one with the rest of us drafted in to try and fill their place. The beach is a lot quieter as adults and puppies alike spend more time out at sea and Hannah spends all day walking up and down the valleys looking for specific puppies to weigh.


Back on base

It's starting to feel like winter as the nights draw in – it doesn't get light until about 9 and is dark by the same time in the evening. As we've all still got loads of work to do we only manage the odd evening off. The best one so far was Craig's birthday. He decided on a Hawaiian theme, complete with barbeque and hot tub: a great way to kick off our winter celebrations.

Not BAS-issue winter clothing.

An unexpected and lost visitor - Cattle Egrets aren't unknown here, in fact one a year is about average, but they still look very out of place amongst the penguins and seals.
