A field team with members from the Natural History Museum and University of Sheffield will spend five weeks in January to February 2013 at King Edward Point research station in Cumberland Bay on South Georgia, Southern Atlantic Ocean. The project is funded through a Research Grant by the Government of South Georgia and the South Sandwich Islands.
The aims of the field trip are to collect samples from soils and streams around Cumberland Bay such as Greene and Barff Peninsula to perform a comprehensive characterization of the bacterial and microbial eukaryotic diversity using next generation sequencing. The sample collection will enable to map bacteria and microbial eukaryotic community richness, composition and geographic distribution. Nutrients analysis for especially nitrogen and iron will also be performed to evaluate the relationship between microbial diversity and nutrients present in soils and streams.
This is important because bacteria and microbial eukaryotes are a major component of soils, and are essential for maintaining terrestrial ecosystems. Microbes are also important for processing of organic biomass and minerals in the soils, and nutrients generated in the soils can be transported into coastal waters through terrestrial runoff, and could subsequently potentially provide a source of nutrients for phytoplankton and fish in the coastal waters of South Georgia.
South Georgia is an island in the southern Atlantic Ocean and located south of the Antarctic Convergence, which is a climatic boundary between air and water masses of the Antarctic and subantarctic regions. South Georgia is around 170 long and between 2 to 40 km wid.
The landscapes of South Georiga characterized by steep barren mountainswith Mount Paget being up to 2.934 m high, numerous large glaciers and snowfields. The vegetation is dominated by mosses, lichen, grasses and a several flowering plant species . Ponds and streams are often rich in algae and mosses (http://www.sgisland.gs).
