The Tristan da Cunha expedition February-March 2003

-

some shots of the field work on Tristan da Cunha island

 

 


The four participants: myself, Karl Ljung (PhD on the project), Dan Hammarlund

and Ole Bennike. The photo was taken just after we had reached The Base, after

600 m of very tough climbing. Note the village between myself and Karl.

 

 

2000 m high Tristan da Cunha seen from Nightingale Island, 40 km away.

 

 

 

Tristan da Cunha seen from a distance of ca 15 km.

 

 

 

Parts of the Settlement Plain, with Hottentott Gulch to the left

and the Hillpiece to the right.

 

 

 

Edinburgh of the Seven Seas, the only village on Tristan da Cunha,

with 285 inhabitants. Hottentott Gulch in the middle

 and the 1961 volcano to the left.

 

 

 

The lava field from the 1961 volcano in the foreground.

To reach one of our sites, Bottom Pond, we had to climb

this 600 m high and steep hill side up to The Base with all our

 coring equipment, including a Zodiac boat and coring platform.

 

 

 

Walking on The Base at ca 700 m a.s.l. with its fern trees

(Blechnum palmiforme), small Phylica trees,

dwarf-shrubs of Empetrum rubrum and mosses.

 

 

An impressive landscape shows up when the clouds disappear.

 

 

 

The heavily eroded and dramatic morphology, with its deep gulches,

between The Base and The Peak at 2060 m a.s.l.

 

 

 

The crater lake Bottom Pond, whose max water depth

was found to be 11 m, with its lush vegetation.

We managed to retrieve 4.75 m of sediments from the lake.

 

 

One of the sediment cores from Bottom Pond.

The sediments are abundant in macrofossils.

 

 

 

Walking back in unstable weather over The Base

 after the successful corings.

Taking a rest after having climbed up to The Base. Note the Big

Green Hill volcano in the background. Without the help of Matthew

(to the very left) and James (Glass) we would hardly have managed

to get all the equipment up, and without James´ help and guidance

 the project would hardly have been feasible. Even James´ dog

Jives looks pretty tired!!
