Lichens grow almost everywhere – apart from the deep sea. As my blog has a lichen focus, it is high time I completed it! We picked up a field party at King Edward Point (KEP), South Georgia which provided new experiences to share with you.

 

We arrived at King Edward Point shortly after 11.00 a.m. on December 17. I checked my GPS. Sunset was at 7.57p.m. and sunrise 2.46 a.m.

Jessica, Malu, Bruce and I disembarked from the JCR together after lunch and set off towards Grytviken. The contrast in the weather since our earlier visit (October 29-30) was dramatic. Snow was scarcely to be seen. Summer had arrived. We certainly did not need to wear many layers!

 

After a brief visit to the museum where we borrowed ski poles to ward off potentially angry fur seals, we set off to explore our local surroundings. I climbed the slope behind Shackleton’s grave to the same area I had visited with Mick Mackey 6 weeks previously.

I met Jessica and Malu walking towards Gull Lake. The lake was frozen when Mick and I last saw it and weather bitterly cold!

I explored the area for lichens and returned to the Museum.

South Georgia Museum, Grytviken, managed by the South Georgia Heritage Trust is located in stunning surroundings amongst spectacular relics of the Norwegian whaling industry. The museum was set up by Nigel Bonner, a former deputy director of the British Antarctic Survey, and opened in 1992. Nigel Bonner was also a Government sealing inspector in South Georgia in the 1950's and among other things undertook the first studies into the then endangered fur seals and reindeer. After his retirement from the British Antarctic Survey (BAS) he returned to SG and set up the whaling museum. Tim and Pauline Carr took over the curatorship in 1992, extending the collection and displays to include the islands natural history, administration, exploration and expeditions and other related maritime history. The museum is visited by thousands of people every year.

I was welcomed outside the museum by Ainslie Wilson, its manager.

30.jpg

I was greeted at the entrance by a magnificent specimen of a wanderer (the wandering albatross), the bird with the largest wingspan of any in the world.

31.jpg

Large specimens such as wanderers and whale skeletons naturally excite everyone and take centre stage in virtually every museum. Imagine my surprise when I found the centre of this exhibit was occupied by much less well known and smaller organisms!

32.jpg

Lying next to a cute albatross chick on its nest is a charming selection of lichens, mosses and fungi which can be found in South Georgia.

33.jpg

A nice selection which whetted my appetite to explore for lichens in a new area – the plateau above the museum leading to Mt Duse.

 

I was greatly impressed by the range of exhibits, the well-illuminated displays and clear labelling. It was a most enjoyable visit. The museum and gift shop is a ‘must see’ for anyone visiting South Georgia. I do hope I shall be lucky enough to be able to visit again someday.

34.jpg

I was soon greeted by a spectacular fell-field carpeted by lichens, mosses and a tussock-forming grass within view of Mt Sugartop and Mt Paget (2934 m), the summit of Allardyce Range, the highest in South Georgia. Wonderful!

35.jpg

I am used to seeing reindeer lichen in Scandinavia and Scotland but did not see it on South Georgia on my previous visit when it was snowy. It is eaten by reindeer which have the right gut flora to digest its polysaccharides.

36.jpg

I admired a king penguin standing amongst dandelions on my return to the ship. Seeing the alien dandelions reminded me how little we know about how lichens are dispersed.

 

Visit to King Haakon Bay

A highlight of our sea voyage was certainly our visit to King Haakon Bay yesterday (December 18) which is challenging to navigate, rarely visited by BAS but a popular route for tourist ships who trace Shackleton’s voyages. We travelled overnight (12 hours averaging 12 knots) from King Edward Bay - a distance of ca 140 nautical miles. I was on deck shortly after 6.00 am as we approached the Bay. Here is a small selection of photos I took on this special day.

First photo I took (6.09 a.m.).

This is where Shackleton arrived from Elephant Island.

It is now Saturday December 19. We won’t set foot ashore again until our ship arrives at Stanley in the Falkland Islands (scheduled for December 31) in time to catch a flight back to UK on January 1.

MERRY CHRISTMAS AND A HAPPY NEW YEAR!

 

William is now en route home where he will begin working on the specimens and data he has collected during his time 'down South'.

Jessica, Bruce and I are now onboard the James Clark Ross (JCR) currently anchored off Wilson’s Harbour, South Georgia before the ship heads North and resumes the Science cruise. Our remaining days at Signy passed all too quickly. An added bonus (as far as Jessica, Bruce and I were concerned) was stormy weather further south resulting in JCR arriving two days late on December 14. An extra 2 days on Signy Island! I shall complete the Signy part of my blog by sharing a special visit with you and local events.


Cummings Cove

On December 9 penguin monitoring and impending bothy maintenance necessitate a visit to the west coast and I am only too keen to join Matt, Dirk and Bruce as this relatively remote habitat is amongst the least disturbed on Signy. It will be an ideal reference site. We needed to cross the glacier so on this trip I carried a ‘rack’, an assortment of karabiners and other climbing gear as a precautionary measure.


1.jpg

Bruce, Matt, myself and Dirk on veranda outside Signy Base The weather bodes well as we set off - sunny weather and blue skies. Liberal suncream and lip balm was applied.

2.jpg

The ‘racks’ or ‘janglies’ as Bruce calls them are not particularly heavy as they are constructed of strong light modern alloys and include a selection of karabiners, ice-screws etc. The crampons packed in a protective plastic bag are less bulky.

3.jpg

Photo taken during a short break at Khyber Pass. Weighing around 20kg, it stood on its own without falling over. A sure sign of a well-packed rucksack!!!

4.jpg

On summit of Tioga Hill (278m) – the highest on Signy.

On the west coast, walking towards Cummings Hut. Coves were filled with brash ice and snow in places, lying deep and right up to the shore line.

At Cummings Hut.

Above Cummings Cove on lower slopes of Cryptogam Ridge. Named for its luxuriant cryptogamic plants (lichens, mosses and other non-flowering plants). Cryptogamic literally means hidden sex organs i.e. they don’t have flowers.

Rocks and soil are completely covered by lichens and mosses.

10.jpg

The summit of Cryptogam Ridge (seen here looking towards Moe Island) is similarly well-covered.

11.jpg

Ascending a blocky scree. Our work involved walking down to the coast and ascending and descending several hills in varied terrain.

Penguin Monitoring. A chin-strap is in the fore-ground.

13.jpg

14.jpg

Our work complete. Returning towards the base. Heavy skies suggested snow and it did snow for a while.

15.jpg

Back at Khyber the snow had stopped and we returned to base, satisfied with a successful day.

16.jpg

A = Signy Base. B = Cummings Hut. My GPS indicated we had walked over 9 miles.

No mechanized transport (skidoos etc) is available for travel on Signy. You do need to use your legs!

 

Local events

17.jpg

One of several Norwegian whaler’s graves on Signy, Cemetry Flats, 7/12/2009. Of the five graves here, this one marks the burial of Aksel Olsen Helstad, born 8/11/1889 died 21/2/1914 onboard SS Normanna from Sandefjord. I noticed the graves appeared on the wrong position on the 1:10000 map (2005) which I confirmed using GPS. It will be some time before this is rectified and a new Signy Map is published. Aerial photography is difficult on Signy on account of the frequent cloud cover. Certainly a lesson not necessarily to believe your map!

19.jpg

Whilst searching for lichens I came across these snow petrels and icicles. In places the snow remained 4 feet deep or more. Taken from the path leading up the Backslope behind Signy Field Station, 12/12/2009

20.jpg

Snow had retreated considerably on the south eastern slopes of the Stonechute with large moss patches apparent higher up, 12/12/2009.


Leaving Signy

Today, December 14 is departure day. Jessica, Bruce and I travelled by tender to the James Clark Ross ship moored in Borge Bay.

21.jpg

Samples were packed ready for shipment to UK next year within view of sparring elephant seals, the old boiler from the remains of a Norwegian whaling station and Jane Peak. Wow!

22.jpg

A friendly wave from an elephant seal - this year’s pup.

23.jpg

I took this panorama on the ship just before 9.00 pm looking north west. Robin Peak which Bruce and I had climbed flitted in and out of the mist. Back on the ship this reminded me that the peak is named after a ship’s captain. The small boat, a humber, is an inflatable rubber boat which provided relief to Waterpipe hut. Sunshine Glacier certainly lived up to its name!

24.jpg

I checked my GPS. Sunset at this location was 9.27, sunrise 2.25 and we had yet to reach the longest day.

 

I am privileged to have experienced Signy from almost Winter to full Summer, all in the space of 5 weeks. The downside was that I needed to sample in exposed sites free from snow. One area I had hoped to sample lichens for a Norwegian colleague below Robin Peak was likely to remain buried under snow until at least January!

0

November 30 was extremely windy, definitely an excellent opportunity to begin sample sorting and packing in earnest! Samples are air-dried back at base in a laboratory for a few days before being carefully wrapped in tissue and packeting for transport to UK next May in ‘cold stow’ under low humidity conditions. I am also databasing specimens on a daily basis, downloading GPS tracks and importing to GIS software and establishing a photoarchive which will help decide the ‘next steps’.

 

50th Anniversary of Antarctic Treaty

On 1 December we awoke to gloriously sunny weather. Strong winds and favourable tide brought in the first major brash ice to Factory Cove. I began to catch up with emails and rescued from ‘SPAM’ one sent to me by a Norwegian aunt referring me to an article on the 50th Aniversary of the Antarctic Treaty. I checked the article online - a rare event for me on Signy as I normally only check emails intermittently.

42.jpg

These are the routes I trekked on the anniversary. I first revisited Khyber Pass. After dinner and ‘gash’ duties, Matt suggested I walk up Observation Bluff. Wonderful!

43.jpg

Examining lichens on Green Gable overlooking the Gourlay snowfield.

44.jpg

Sunset over Coronation  Island from Bernsten Point, 20.59 hours. According to my GPS sunrise was at 02.39 and sunset at 21.03.

 

Coastal lichens

Coastal lichens are especially well adapted to life in harsh environments and are influenced by salt, temperature and other factors. They are at times completely immersed by sea water. I have been asked to collect samples for several colleagues at the Natural History Museum and elsewhere.

45.jpg

A marine lichen, collected from Cemetery Flat – my only sample of a coastal lichen so far! A similar black lichen in the Shetland Islands, Scotland, UK was mistaken for oil after an accidental oil spill.

47.jpg

Bruce and Jessica crossing Cemetery Flats. The ice is beginning to melt and break up. They crossed successfully and avoided getting wet! I decided not to examine coastal lichens on this occasion but to head back up the valley to Khyber.

 

Next steps

Jessica, Bruce and I probably have 10 days to go before we leave Signy. Our ship, the James Clark Ross is currently at Rothera but its itinerary is delayed owing to heavy storms. As well as returning home and to the Museum, I look forward to visiting colleagues at the British Antarctic Survey on January 11 and to consulting their collections. However, an extra day or two on Signy will be a bonus!

 

I consider my visit to be a success in spite of the snow and hope my visit and the samples I have collected will prove useful to others. I am extremely grateful to everyone for their support in making my visit possible.
