Between August 2008 and April 2018 I spent a number of years working on Signy Island (South Orkney Islands) and Bird Island (South Georgia) for the British Antarctic Survey (BAS). I worked as a Zoological Field Assistant on the penguin, seal and albatross long-term monitoring programme. After a 5 year break, i'll be heading back down to Bird Island in Janary 2024 for another dose of penguin work.

This blog gives readers an insight into my day-to-day life in the Antarctic, from my first trip south in 2008 to the present day.

The largest iceberg in the world

Part way between Signy Island and the Falklands we took a small detour to visit the largest iceberg in the world, unimaginatively named A23a.  This berg broke off from Antarctica in 1986, and remained grounded on the sea bed for many years.  In 2020 it started slowly moving northwards and now lies pretty much on our route home.  It is currently a massive 40 miles long by 32 miles wide and is a huge flat sheet of ice, with edges beautifully scalloped by the incessant battering of the southern ocean waves.  We were able to get quite close to it and get some amazing views.

One morning at sunrise we were treated to some very nice anti-crepuscular rays- these are like the sun rays you see around a sunrise, but with the added confusion of being on the horizon directly opposite the sun instead of around the sun itself, resulting in something that looks like a sunrise but without the sun!

On our final morning at sea we were treated to a lovely sunrise. 

We have now arrived into the Falkland Islands where we are spending a week there before flying home on 9th April.  We are still aboard the ship and are moored at Mare Harbour, which is the military port that supports the RAF base at Mount Pleasant.  It is in the middle of nowhere, about an hours drive from the capital Stanley, so we have hired a car so we can get out and about and see the islands.
