Summer Days Drifting Away

Though the sun has yet to fall below the horizon since my arrival at Halley, there is a noticeable evening which was not present a month ago, indeed the sun will set for the first time this year in a few days time if only for an hour or so.

The temporary disappearance of the sun coincides neatly with the end of the Halley summer season, for the ship is already keenly waiting for second call to begin and the long shifts of sledge towing Sno-cats will make the journey to the coast but on this occasion taking out the waste (including all the building materials) produced over the last six or so weeks. More importantly the bulk of the winterers from last year, apart from six who are staying for a further year, along with the summer team will also be leaving.

We have all been fortunate to spend some time up with the plane- I, particularly, since I had the opportunity to sit up front as co-pilot. All BAS flights require a second person to fly, as there is no solo flying by any of the pilots, all that the co-pilot training involves are basic field skills including pitching a pyramid tent along with lighting Primus stoves and a Tilley lamp, so that there is somebody to assist the pilot should poor weather force the plane to land in the middle of a storm. No flying skills or knowledge are required!

Unfortunately, despite taking far too many photos, the poor contrast that has blighted a lot of the summer meant that there were few of great worth. However, the aerial photos of the base should mean that I can give a quick guided tour of the base, though I intend to elaborate on most of these over the winter.

Aerial Map
Again from the north-east as above but further away


From Left to Right:

CasLab or Clean Air Sector Laboratory- (off the map) it sits almost 2 miles from the base towards the plateau and is surrounded by a large no-entry sector allowing ultra-clean chemical sampling to study the chemistry of the interaction between the atmosphere and ice-sheet.

Simpson platform- one of the three main platforms at Halley, it houses the offices of the meteorology team (known ubiquitously as MetBabes- Kirsty, Tamsin and Dave) along with some of their equipment. Thomas also works from here running an exciting project to be covered another time but involves flying an unmanned aerial vehicle.

SHARE- there are seemingly innumerable acronyms within BAS Science and I cannot remember what this stands for. Basically, it is a long structure dominating the southern portion of the base involving a sequence of large pylons used to study the upper atmosphere.

Piggott platform- the second of the two science platforms, along with the Simpson. From here Alex, Jules and Chris look after the many upper atmosphere experiments (including the SHARE), that run around the base and further afield.

Laws platform- the centre of the base and the largest structure. It houses all the accommodation and living areas (including kitchen and dining room), as well as many of the technical services workshops (into which category the surgery should probably also fall). The Base Commander's office, Comms (communications) office and Field store are also all here.

Drewry- though the Laws can accommodate up to 40 people, this is exceeded substantially in the summer, for which the Drewry provides further accommodation along with a mess room and kitchen (complete with cook). In a few days it will be closed down and its generator switched off, though it provides a back-up should a catastrophe wreck the Laws.

Flying Over Crevasses


Garage- life at Halley would be difficult without the large vehicle fleet, which are maintained all year round from the garage. Like the Drewry, it is a large building on skis and is annually dug out from the large windtail it accumulates and moved to a new site.

Container Line- given the reasonable but limited space on the platforms a long chain of containers provide alternate storage year round, which extends at the northern end to the winter dump line, where vehicles and large objects not needed for the winter are placed on large mounds of snow so that when the summer returns, they should be level with the snow again.

Skiway- the airstrip for Halley (see Planes, Cranes and Ski-doos)

Fuel Stores- the various fuels, the large majority of which is Avtur, is stored in large bulk fuel tanks or in its original 45 gallon drums, well away from the main area of base for obvious reasons.

There are plenty of other smaller buildings and features around the base, which fail to appear in the photo above.

The Piggott Platform
At around 20 knots snow blows across the ground like a sheet


The three platforms are built up on stilts to allow them to be raised frequently to keep them away from the snow surface, which would result them in being buried. The previous Halley bases, were abandoned as they sunk deeper under the ice surface and were crushed by the accumulated weight. The raising of the Laws platform usually provides a labour intensive and painful focus to the summer, given the imminent re-location of the base in probably three years, this happened for the last time last summer.

However, all still the platforms need some tweaking given the different snow accumulation around each leg and the resulting strain on the buildings, which the steel erectors (steelies) have spent at least a week rectifying.

A large proportion of my time in the last few couple of weeks, has been spent planning the base Major Incident Plan (MIP) exercise. Given that the base during the summer has only a single doctor, an accident involving two or more seriously injured people would stretch the capabilities of the base; this is in stark contrast to the much larger scales of disaster required to trigger a MIP for a hospital in the UK.

The purpose of the exercise was to test the logistics that should support the response should such a disaster occur here. The scenario revolved around a welding accident resulting in a loose gas cylinder acting as a missile- a not unforeseeable though unlikely disaster wherever welding occurs. Given that only myself, the casualties and observers were aware of the nature of the scenario- though the rest knew the exercise was going to take place- it was important to make both the incident site and the casualties as realistic as possible, while ensuring the risks of a real accident were minimised. Hence- beware pictures of fake blood below!

Alongside myself the medical response is provided by a handful of advanced first aiders, who in addition to the extensive Antarctic first aid course that everybody who goes South attends in Cambridge, they spent some extra days in Plymouth covering a variety of advanced skills, including cannulation and suturing prior to coming South. Doc School, which all the Docs run at the various bases through the winter, will give everybody a chance to learn more as well as stopping me getting too bored!

The exercise had four simulated casualties, though not all at the site of the initial incident, all of whom were made-up and acted out their injuries- they all did a great job and the exercise would not be as realistic without them. As the photo below hopefully shows, a lot can be achieved with golden syrup and red food dye.

The whole thing lasted a couple of hours and then took almost as long to tidy away. The most noticeable problem here is hypothermia, even in the UK MIP exercises frequently note that hypothermia is a significant problem, a feature exacerbated in the Antarctic, even when one is aware before hand that it is a problem and try to keep the casualties as warm as possible and is despite the weather being not inclement on the day of the exercise.

The whole exercise was certainly useful not only for myself but also the first aiders and refining the base Major Incident Plan, should the worst happen. As the summer draws to a close, there is frantic activity preparing for second call and the long winter that lies beyond it.
