One of the highlights (so far) of this winter on the ice has been, without doubt, the opportunity to observe the effects of having open water in front of Scott Base. Usually a year-round frozen ice shelf, the open water has brought some spectacular sea mists and not just the usual populations of Weddell seals and Adelie penguins, but large numbers of killer whales and Emperor penguins (and even the occasional cruise ship!) … to literally right outside our windows. Beats television!

Each day we have had the pleasure of watching a group of about 50 Emperors (all adolescent males, I'm told) huddle, fish, play, squawk, dive and scoot around (belly down) on the ice edge. And occasionally they'll take a long walk across the ice to what seems like nowhere in particular, usually in single file and in a very determined fashion, only to huddle for a while before returning again by foot or from beneath the ice through an open pool or crack. But, alas, as we head into our last fortnight of daylight before the austral winter darkness sets in, the sea now looks to have frozen over and, sadly for us (and perhaps also for them, as they may have been equally fascinated by the behaviours of Scott Base residents) the last of the Emperors have walked off … to somewhere else.

Oh the frustration of losing things. It's a bit late for the owner now but it's nice to have found his second sock. Of course it couldn't have been in the washing machine, and it wasn't under the bed. It was in fact under the floorboards of Discovery hut. Why and how did it get there is anyone's guess. The magical mystery of missing things may never be understood. Interestingly though, the sock was also under the floorboards with other objects including empty ration bags, twine and cordage, a dust-brush, sardine can and safety pin.

The objects were recovered from under the floor by the outgoing AHT summer team who were undertaking structural stabilisation work on the hut which involved lifting some of the floorboards. So how did these objects manage to find their way there? Of course we can only speculate but it's likely they were simply swept into a hole in the floor which had been created by the Ross Sea Party.

The empty ration bags are unmarked and so we can't ever know what meal they contributed to. One of the bags is still tied at the top and ripped open down the side. One appears to be covered in cocoa and white crystalline grains, perhaps sugar. Taste testing is not advised for obvious reasons. Others contain a soft waxy substance also of unknown identity. I'm curious as to what they actually contained and what the men were up to on the day they emptied those bags. The image below shows the ration bags drying after being washed to remove damaging acids and salts. All stains, soot and contents are retained as important historic information.

Another interesting part of the underfloor assemblage of objects is a beautifully retained length of twined rope with a particularly strong smell. The smell isn't altogether unpleasant but it's distinctive as you open the door to the workspace each morning. The smell is very similar to pine tar which was used to saturate hemp fibres for pre-prepared wooden ship caulking, which is likely the purpose of this rope.

It's been an interesting week contemplating the discarded or lost objects under the hut and I wonder if the loss of that sock was ever of torment to its owner.

A paper conservator back in Spain, I arrived in the Antarctic knowing that the artefacts I would be working on for the Antarctic Heritage Trust would be very different to the European manuscripts I am used to.

Last week I had a very good example of the challenge that represents the conservation of a paper artefact here. Two wads of paper arrived on my bench in such bad condition that all the fragments of pages were stuck together.

Before treatment artefacts

 

The challenge that I was presented with was multiple; being able to understand its structure, identity, history and devise a conservation plan appropriate to the context of Scott's Discovery Hut, where the items were found. The paper was very fragile and the shape it arrived in was the result of degradation. Moreover, I had to make the correct decision about the presentation of the artefact after treatment, for its return to Discovery Hut.

Sharing opinions and knowledge with my colleagues was very beneficial as well and together we made a decision. I discovered that the fragments were from two different newspapers, one unidentifiable and the other one from a British newspaper called 'The Review of Reviews' published in July 1893. Thanks to this information and the known history of Discovery Hut (built by Scott and his party in 1902 but where various expeditions also spent time), we decided to keep the artefact folded so as to not intervene with the shape in which it was found, but rather to access as much information contained within the pages themselves through the conservation treatment.

In Discovery Hut there is a bed (or sleeping platform) that is composed of a section of tongue and groove, originally from the ceiling of the hut itself and positioned on supply boxes beside the stove area. The area surrounding the stove became a cozy den for several desperate explorers seeking security from the harsh Antarctic environment. In the words of Dick Richards of Shackleton's Ross Sea Party (Imperial Trans-Antarctic Expedition 1914-1917): The hut may have been a dark cheerless place but to us it represented security. We lived the life of troglodytes. We slept in our clothes in old sleeping bags which rested on planks raised above the floor by wooden provision cases.

Before returning to Scott Base this week, Meg and I completed the conservation of the supply boxes that raised the bed. After many hours working in the soot and seal blubber drenched dark room, we learned how to overcome the difficulties working in the cold and dark of the hut. We wore leather padded gloves as opposed to nitrile gloves, which freeze immediately in cold environments. We wore Extreme Cold Weather gear and head lamps as opposed to our white lab coats and magnifying bench lights. We also defrosted ice to wash our tools and hands on the stove that we light every morning in our working container nearby.

We devised a method to systematically map each piece of the bed platform so that upon their return after conservation our interference left minimal mark. As well as leaving minimum traces of our presence in the hut, by taking back all of our equipment and waste to Scott Base every night we also left no trace in the environment.

The world has changed exponentially since I began my professional life as an archaeologist… back in the olden days when hardcopy books and journals were our main sources of information. One of the more remarkable changes is without doubt the access we now have to information on pretty much everything, via the internet. A good example occurred this week as I was treating artefacts from Robert Falcon Scott's Discovery hut, down here at Scott Base. The hut was constructed in 1902 by Scott's 1901–04 expedition, was used a number of times by Shackleton's 1907–09 expedition, used for periods by Scott's 1910–13 expedition, and again by Shackleton's depot-laying Ross Sea Party in 1915–16. The US Navy was next to visit in the late 1940s, a US research base grew alongside it from the 1950s, and a group of NZ volunteers carried out some restoration work in the early '60s, and fitted a lock to the building for the first time. So there is a long history of activity in and around the hut, which was found filled with snow and ice on several occasions, and emptied. Artefacts that remain there today could date from any of the 'heroic-era' periods of use or subsequent visits, so it's interesting to ponder how and when an artefact came to be there … and particularly satisfying to discover some evidence of its age. An object I was working on this week revealed just such information, with more than a little help from Google. It was a Primus stove made by a Swedish company, and now covered with a thick layer of black soot from Discovery hut's seal-blubber stove, suggesting it dated from one of the early expeditions. Whilst stabilising the corrosion, I discovered a small letter 'D' stamped in the base beneath the soot layer, and a quick search revealed that, from 1911, Primus stoves made by this company were stamped with a letter to indicate their year of manufacture! How convenient is that?!

 

AHT11032_1!_Side2_AT.JPG

 

So this one was made in 1914 … after Scott but in the same year that Shackleton's Ross Sea Party was stocking the refitted SY Aurora in Australia in preparation for laying supply depots for Shackleton's unsuccessful Imperial Trans-Antarctic Expedition in Endurance. Aurora took on supplies in Sydney and then more in Hobart before heading south in late December of 1914. So this Primus, brand spanking new at that time, almost certainly made its way from Sweden to Australia to be procured by the expedition in either Sydney or Hobart, travelled to Antarctica on Aurora, and was used in the hut by the Ross Sea Party. Cool! And that was revealed in just a few short minutes from the comfort of Scott Base, on the ice, via satellite. Whatever did we do before Google … or modern technology, for that matter?

Dog biscuits

I’ve been very fortunate since arriving on the Ice to be working in the on-site conservation laboratory at Hut Point, which is situated directly behind Scott’s Discovery Hut (1901-04). Stefanie and I have been conserving food boxes from an internal wall made from stacked supply boxes. This wall was built during Shackleton’s British Antarctic Expedition (1907-09) when they used Discovery Hut as a staging point for depot laying. The Hut is described by various expeditioners as a dark and cold place to spend time and Shackleton’s men wished to enclose a cosy space around the stove to make the quarters more habitable. The supply boxes used were predominately Special Cabin Biscuits and Special Dog Biscuits made by Spratts Patent Limited of London, who also supplied the army and navy.

Every time we walk into the Hut we get the chance to imagine the many stories and desperate situations the men who passed through Discovery Hut experienced.  It’s incredibly exciting conserving the boxes that make up the internal wall in the Hut as we discover new and different details every day.

Dogs are also part of the amazing history of the Hut, with Scott taking 23 dogs for hauling sledges on his National Antarctic Expedition. In 1908, during Shackleton’s Expedition, three puppies ended up at Hut Point. It was decided to leave the puppies in the Hut for nearly a month while depots were laid for Shackleton’s push to the Pole. Dr Eric Marshal recorded that 24lbs of mutton was chopped up for the puppies as well as dog biscuits and snow left for their survival. The men returned to find the puppies had eaten all the mutton but not the biscuits.

The highlight of my week was discovering two puppy paw prints inside one of the boxes. The prints were made from seal blubber which was throughout the Hut at the time as it was used as fuel for cooking and warmth. Dogs are no longer allowed in Antarctica but we’d still love to have one to play with.

This is my first time in Antarctica, and since I have been here, each day is more surprising than the day before. After two weeks of getting to know the new lifestyle and the objectives of the paper conservation work, I went last week for an evening walk. Two friends from Scott Base working for Antarctica New Zealand came with me. We were enjoying the sun and the weather, still warm at the end of the summer (already -15 ⁰C). Walking here means being well covered especially because of the wind and the temperature, but the landscape and the silence around are very special.

The cross at the top of Observation Hill last Friday

 

We went up Observation Hill, between Scott Base and McMurdo Station, where a cross was erected in 1913 in memory of Captain Robert Falcon Scott and his party who died on their return from the South Pole the previous year. Because of the difficulty of the path to the top, and the surrounding landscape, reaching the top and arriving at the cross was a very moving experience for me … I realised the danger and the exceptional lives of these men, who came to Antarctica more than a century ago.

After having spent my first week on the conservation of artefacts that represent their quotidian life in the Antarctic in Scott's Discovery Hut—their food, their tools, their clothes, etc.—and getting to the cross, I had a completely different feeling about these artefacts and realised in a very concrete manner the exceptional qualities of these men. Top view, top memories …

The stories of an artefact

Returning to visit Scott's Terra Nova hut at Cape Evans was an incredibly rewarding experience. The sun was especially bright that day making our view from the helicopter ride from Scott Base sensational.  Upon arriving we found Adelie penguins and seals playing in the shore break. Entering the hut is a magical experience where one steps back into the time of the historic explorers.  As we walked around the hut I noticed several objects that our previous winter team (which I was part of) conserved and had been returned to their place in the hut by the recent summer team.

 

The stories associated with artefacts play a major role in their interpretation, historical significance, value and conservation treatment and upon seeing the artefacts we conserved, I felt a personal connection and a new story that I associate with those artefacts. I was reminded of all the conversations, the deliberations, the analyses and the treatments that we carried out last year. I remember the excitement in the lab, when Stefan conserved Clissold's cooking pot, which now takes prime place in the kitchen area of the hut.

The Finnesko boots, which I spent so many hours reshaping and rediscovering now hang at the Hut's entrance.

Not only did Marie conserve an enamel dish uncovering the residue of caramelized sugar on its edges, but also convinced our chef to recreate a Scott style rhubarb pie in a similar dish at Scott Base, which we all thoroughly enjoyed. That enamel dish now sits on the wardroom table in the officer's area in the hut.

I look forward to the stories that I may associate to the artefacts I conserve this year!

With environmental awareness, survival skills and effective team processes topping the agenda, the incoming AHT winter team got stuck straight into Antarctic Field Skills training following our arrival on the ice last week. This included a couple of days out on the ice shelf (in spectacular weather, thankfully), forming teams to carry out a variety of tasks and learning or refreshing some vital skills.

 

Image 1 (Small).JPG

Getting started and discussing the design

 

After selecting appropriate layers of clothing for the minus 12-degree temperature, preparing our individual sleep kits and pitching our polar tents, we set about designing and building our kitchen in which to shelter from the breeze, light our stoves and boil water to prepare our dehydrated dinners-in-a-bag. Using saws and shovels to cut and lift ice blocks, we simultaneously created a pit and constructed walls, not forgetting some seating and a bench for cooking. Being somewhat easier than it sounds, before long our far-from-perfect but nonetheless perfectly adequate little ice-kitchen took shape.

Looking good - the team relaxes in the ice-kitchen

 

In we piled, and some reasonable curries and pasta dishes (and considerably better camaraderie) were enjoyed late into the bright sunlit night.

 

Good training … good fun!

What an exciting week it's been for AHT on the ice! A shift change has brought four fresh conservators to Scott Base for the winter-over season and a much anticipated home-coming for the summer conservators and carpenters. For a short time we’ve been a group of nine AHT staff at Scott Base.

The 2014 winter-over team consists of Lead Conservator Sue Bassett (AUS), Stefanie White (IRE), Aline Leclercq (FRA) and Meg Absolon (AUS). Following a whirlwind of introductions, inductions and field skills training we're all excited and ready to unpack artefacts from Scott's Discovery Hut for conservation treatment. And just to top off a fabulous first week in Antarctica, a pod of Orcas swam past the dining room at dinner time. Thanks for the welcome!

This summer I spent several days conserving the Fleuss vacuum pump found on the bench in the science corner of the Cape Evans hut. This is a hand powered single cylinder vacuum pump made of cast iron and cast brass.
Pump before treatment (Small).JPG

The pump would most likely have been used for drawing a vacuum in a bell jar in order to run chemical experiments at 0 pressure, or to draw chemicals through a filter system for experiments. It was made by the Pulsometer Engineering Co. of Reading, England, from a design patented by Henri Fleuss who was famous for inventing self contained diving apparatus in the late 19th century. He called this model the Geryk after the German scientist who invented the general style of vacuum pump in the 17th century.

The pump was heavily corroded, having been exposed to over a century of high humidity and regular freeze/thaw cycles. Most of the ironwork had been painted black at one time and part of the vacuum bulb and the pump cylinder had been painted red, however, only flaking traces of the paint remained.
Pump after treatment (Small).JPG

Remnants of mercury in the bottom of the bulb and the valve chamber of the pump has resulted in chemical degradation amalgamation leaving some of the metal porous and crumbly. We are unsure of the purpose of the mercury, and would be interested in any knowledge our readers can give us as to its purpose within the pump.


One unfortunate side effect of contact with mercury is that the solder and brass of the vacuum bulb has become very fragile and has cracked around the base.
Cracked bulb (Small).JPG

To conserve the item, the rust was reduced with hand tools and abrasive pads then the remaining rust was converted with a tannic acid solution. The resulting dark surface was coated first with acrylic lacquer and then with microcrystalline wax. A brass rod splint was fashioned to hold the cracked bulb in place.


The treated pump will resume its place on the end of the science bench, now stable and protected for many more years.

It’s hard to believe that in early November Sy, Lizzie and I made the trip from Scott Base to our new home which is just a short walk along the beach from Scott’s Terra Nova hut at Cape Evans (built for the 1910-13 British Antarctic Expedition). Travelling in a tracked vehicle known as a Hagglund we headed out across the sea ice following the route frequently taken by members of both Scott and Shackletons expeditions around the shoreline below Mount Erebus. Behind us we pulled sledges of supplies to sustain us for 3 months, and the historic artefacts that we are returning to the hut after conservation treatment.

Our camp is basic but comfortable and we soon settled in and now feel quite at home. Whilst we each have our own tent for sleeping other areas are made up of converted freight containers towed over the ice and left on site from year-to-year. Two adjoining containers are used for cooking, eating and warming-up and the kitchen area has a diesel fired stove on which two pans are constantly melting snow for our water supply.  The views from the windows over the sea ice are spectacular.

 

Tents at Cape Evans.jpg

We have all the basic staple foods for cooking and Sy has constructed an ice block freezer outside for our meat, cheese and vegetables that need to stay frozen when the temperatures edge above zero during the summer. The kitchen has a gas stove and oven, a breadmaker which I love using, and a yoghurt maker. We carefully sort and label our rubbish and the poo from the bucket in the little toilet block before sending it back to Scott Base and NZ for disposal.

 

We can communicate with the outside world by radio to Scott Base and by a satellite phone to the rest of the world.  The electricity for computers and charging batteries is provided by solar panels.

Working in Scotts hut we find ourselves asking questions about the daily lives of the men that lived there, and these often echo questions asked by friends and family as they try to imagine our camp set up. If you have any questions about how we live – just ask.

I love sunsets. The setting of the sun can be serenely pretty or transcendently beautiful. I spent many years fighting forest fires and saw some truly spectacular sunsets coloured by the smoky air. Here in Antarctica the sunsets have been especially wonderful.

Each sunset down here is a treasure because there aren’t very many of them. The day that I arrived in Antarctica, 1st Sept, was the first day that the sun had peeked above the horizon in about 4 months and it quickly dipped to the first sunset of the spring.

From 1st Sept to 22nd Oct we had a series of wonderful sunsets. They can last for hours here as the sun gradually slopes down toward the horizon turning the sky from pale blues to rich oranges, yellows, and fuchsias, then gradually through pastel purples and rust hues and finally into deep indigo.

Each sunset becomes shallower and longer as the days lengthen until eventually the sun just barely dips behind the horizon.

And then it sets no more. We had our last sunset of this year on 22nd Oct. Unfortunately we had 2 days of clouds and snow on the 21st and 22nd so the technical last sunset wasn’t visible, but I did manage to get some good pictures of the sunset on the 20th.

Now, although the sun no longer sets, it does sink low and traverses the Southern horizon throughout the night. For several more days, or maybe weeks, this will give us wonderful long, almost sunset shows of golden orange skies throughout the night.

Eventually the sun will be high enough that there will be essentially no difference between night and day. Some time in February the process will reverse and the sun will gradually work its way back down to the next sunset on 20th Feb. Here at Scott Base we celebrated the final sunset of this year in grand style with the traditional Hawaiian Luau themed party.

When we arrived at Scott Base, Josiah and I joined a small team of 10 people who had just spent the winter on the ice. Whilst it was busy, it was also relaxed and quiet, but suddenly it’s all change. The summer season has begun and the base population has swollen to over 50 excited people, many of whom have not been to the ice before.

Last weekend we got to know some of the new crew as we joined them to learn Antarctic Field Skills from the specialist trainers – how to survive in the Antarctic environment, while working, having fun or in an emergency. 

 

We put together sleep kits of layers of thick sleeping bags, collected food supplies, learnt how to light camp stoves in sub-zero temperatures and discussed how to protect ourselves from frost bite. We then headed out to spend the night camping in tents similar to those used by the early Antarctic explorers.

That evening, after digging a kitchen area protected by snow blocks, we heated water and dined on packets of dehydrated food. When we turned in at 11pm it was still light and the weather perfectly calm. But this is Antarctica! Overnight the winds increased and in the morning we emerged from our flapping tents into near blizzard conditions. Although I’ve done field training on my two previous trips to the Ice it was always in fine conditions, so I really enjoyed experiencing some ‘real Antarctic weather’.

Preparing to de-camp

    

Thanks to the training Josiah and I now feel confident as we make plans to head out to spend three months camping at the historic hut sites.  We are definitely looking forward to the experience.

It's about science

Posted by Conservators Oct 3, 2013

Life in Antarctica is and has always revolved around scientific study and discovery. When Captain Scott proposed his expedition to the South Pole in 1910 he felt that the primary purpose of the expedition was scientific study. He commented in his journals that if they reached the pole then people would pay attention to their scientific research. If they failed to reach the pole then their expedition, with all of its discoveries, would be largely ignored.

Today science is still the driving reason for work in Antarctica. The American McMurdo station is run by the National Science Foundation and New Zealand’s Scott Base, run by Antarctica New Zealand, is used primarily as a staging area and support base for a variety of scientific projects each year. Now, as then, much of the research done on this continent is environmental study. Researchers here study the movement of the Polar ice sheets, particulate concentrations in the upper atmosphere, air and water temperatures, weather patterns over the polar region, biology of the marine life, and any number of other subjects that may have subtle but wide reaching implications for the world in general.

As a part of that research, the staff here at Scott Base periodically measure the thickness and temperature of the sea ice in this arm of the Ross Sea. A couple of days ago I had the opportunity to join Scott Base staffers Mike and Tim for an evening trip to check on one of the sea ice probes in the bay. We travelled about 25 kilometres by Hagglund to reach a small instrument table anchored far out in the middle of the ice. Without a GPS it would be difficult indeed to find this one speck in the middle of the vast white flat. They downloaded the recording from the array of thermometers buried through the depth of the ice, changed the batteries in the device, then drilled a new hole to check the current thickness of the ice and of  the layer of soft ice crystals forming on the underside of the sheet.

As we left the remote site we had a beautiful view of sunlight piercing through the clouds onto one of the glaciers that feed ice into this sea.
