Fieldwork at Flarjuven

Saturday, January 31st, 2009

Boy… lots been happening.  Will try to make some nice posts soon, but in the meantime, here are some photos from fieldwork yesterday at Flarjuven Nunatak, 42km south of SANAE IV.  I was assigned as a field guide to our two geomorphologists,  who had to travel to the nunatak to download data from a temperature logger.  The logger is situated on the margin of an area of patterned ground – movement of the rock due to temperature changes creates patterns in the surface – and records both air and ground temperatures at various depths throughout the year.  We flew in, established an emergency camp (the wind was unpleasant and very cold at that altitude) and completed the data download  and maintenance before flying out in a hurry as the weather deteriorated once more.  Pictures below:

On their way…

The SA Agulhas left Cape Town harbour on December 23 on her southbound voyage to Antarctica, bringing the summer researchers, support personnel, and the new overwintering team (SANAE 48).  We will be training them and handing over duties during January and February, so that they can take the expedition forward for another year.

You can keep track of the progress of the Agulhas – now just entering the Roaring Forties – by clicking on the link in the sidebar labelled ‘Track the SA Agulhas’.  In January she should reach the German Station, Neumayer, then move to Blaskimen Butka to the east to offload fuel before a bouy run to the South Sandwich Islands and South Georgia.  She then returns to Antarctica to backload all the cargo and waste from SANAE, as well as us, before sailing to South Africa in March.  Using the link, you can zoom and pan the map to see exactly where she has been, the weather and sea conditions, etc.

My contacts (spies!) aboard the ship tell me that they sailed intto 5m swells directly after leaviing the Cape, keeping the new doctor very busy with sea-sick patients!  The Agulhas’s ice-strengthened round hull makes her quite susceptible to roll, and they have to navigate a set transect for the oceanographic research, so it must have been hell for those prone to motion sickness… and the Forties and Fifties still await!  Fortunately, ice conditions this year are much lighter than the last.  You can read an interesting and informative summary on the ice conditons by Ian Hunter of the SA Weather Service here.

Yes, these are a little overdue.  Still worth it – beautiful sundogs and a 10-degree arc.  Enjoy!
