Melanie Leng is currently part taking in an expedition to the Southern Ocean as part of ORCHESTRA (Ocean Regulation of Climate by Heat and Carbon Sequestration and Transports), a NERC funded programme with partners at the British Antarctic Survey (lead), the National Oceanography Centre, Plymouth Marine Laboratory, and many more including BGS. Here she updates us on her journey so far...

Since this is geoblogy, a bit about the rocks! So far I have only seen quartzite and basalt. The quartzite is a hard, grey, layered rock (Silurian and Devonian sandstones?) which outcrops within Stanley. Many of the older houses are built from it. The basalts sit on top of the quartzites in the surrounding hills - and are therefore younger. Between 1996 and 1998 the BGS re-surveyed the islands and produced the first modern geological map.
I am tweeting @MelJLeng and @ORCHESTRAPROJ and Facebooking (Orchestra project) during this trip, as well as updating the BGS Geoblogy and drakepassageblog.wordpress.com when I have time.
Melanie Leng is the Science Director for Geochemistry at the BGS and the BGS lead scientist for ORCHESTRA.
