Our last field trip was to Harpon Bay. Unfortunately, we managed to pick one of the most rainy days of our whole trip. Nevertheless, we still got some good samples, and even more enjoyed dinner and a warm cup of tea in the evening. The main glacier in Harpon Bay is the Lyell Glacier which is highly covered with debris. It is also a very active glacier with a lot of calving.

But, now it is time to say good-bye to South Georgia. After 1-month of extensive sampling, we now have an interesting set of samples to take back to the UK for further analysis. The last two days, we spend cleaning, packing, and getting our samples ready for shipping.


We left South Georgia on the James Clark Ross (JCR), one of the British Antarctic Survey's research vessels. The JCR arrived on a windy morning and we were all transferred by jet boat onto it. The JCR left Cumberland Bay as soon as we were onboard, and we waved King Edward Point goody-bye.

Before the JCR headed towards the Falklands Islands, there was another stop at Bird Island, a small island at the northern tip of South Georgia. A few people joined us from there, and some re-supplies were loaded off. It was a cloudy morning, but Bird Island still looked beautiful. A multitude of birds such as petrels and albatrosses could be seen.


After a few hours at Bird Island, we headed for the open sea. While we were on the JCR , we had a chance to visit the labs and find out more about the science happening on the research cruise. We were lucky the sea was pretty calm throughout our journey, and after 3 days we arrived in Stanley, Falksland Islands. From here, we jumped on a plane to get back to London.

In our project, we would like to investigate how microbial communities  differ between soil types. Therefore, we need to characterise the soil types and chemistry of the soils. This will entail measurements of pH, moisture content and nutrients such as nitrogen, phosphorus and iron.


The pH and soil moisture were determined straight after the collection on return to King Edward Point.  It makes quite a big mess in the lab, but worth it! Nutrient analyses are more complicated and therefore will be done back in the UK.

We also measure pH, conductivity, oxygen and temperature for every stream that we sample, but this has to be done directly at the sampling site. For continous measurement over several days, a data logger was also installed in a stream near the station.

Corral Bay is small bay on Barff Peninula. The shores along Corral Bay are covered in a maze of tussock grass and big water-filled wallows, which is very common for South Georiga. The bay leads to a small valley with grasslands, bogs and bright green moss streamsWe also got to see a Sooty Albatross (Phoebetria fusca) pair with their chick, which was a real treat for us.


The next day, we were picked up again by the the King Edward Point (KEP) boat crew and headed back to KEP in a slightly choppy sea. There was a lot of ice from icebergs and glaciers, which must have been pushed into this part of Cumberland Bay by the wind.

South Georgia's flora is particularlly rich in cryptogams. While hiking across hills and mountains in South Georiga for interesting soil sampling spots, I also came across a lot of beautiful lichens. Common lichen genera were Caldonia, Usnea and Diploschistes.  There are also several fern species growing in South Georgia and hude amount of moss species, which often cover whole streams; so called "moss streams".
