Is Antarctica gaining ice?

What’s behind this story and why this publication is highly questionable.

By Bianca K.

Last week a newly published paper ( stated that the Antarctic Ice Sheet is actually gaining and not loosing ice. A statement that is quite the opposite to pretty much every other scientific study on this topic.

No need to mention that this sparked a new debate and released a media storm.

It’s a plastic world

By Biance

Following previous blog posts about plastic in our world, this is a new video everyone should see and share.

We are living in a world where everything is wrapped in plastic, quite often unnecessarily in tons of plastic.

I remember when we bought some cutlery and discovered at home that every single fork, every single spoon and every single knife was packed into it’s own private plastic bag just to be wrapped once more into a larger bag to bundle all forks, all spoons and all knifes to pack them once again in a plastic bag. It was not just a total waste of plastic it was also very annoying to unpack.

Maybe I shouldn’t have unpacked it, maybe I should’ve just give it back and try a different company but hey, who knows how often I would’ve need to return the new cutlery until I find a company that doesn’t use that much plastic?

A lot of plastic

Unfortunately, these days, because we have it and we can do it, companies just use it, everywhere and for everything. They don’t care about the environment as long customers buy their products. And that is where we can change things. It might seem like nothing, it might seem like there won’t be any change if we, as an individual person, act ecologically but if we all start thinking about the way we live and start to take care of our environment it is not just one single person but many of us and that can make a difference!

And yes, I should have given the cutlery back and try a different company! But at least I kept the plastic wrap somewhere at home in a corner so I can reuse it should I ever need some wrapping paper, whether it’s for cutlery or something else but this way I’ll not have to buy any more plastic for quite a while!

The Amazon rainforest tipping point

By Biance

Last night I watched an interesting documentary on the Amazon rainforest dealing with the consequences of a changing climate. The documentary is part of the 6-prt TV climate series ‘Tipping points’ and investigates how the rainforest manages to deal with our shifting climate.


Parts of the forest show first signs of changes, with big trees dying and fewer growing as these trees need a lot of water to stay healthy. While the death of such huge trees causes a fair bit of destruction, new trees emerge in the gaps. However, these are smaller trees that need less water and grow less high. Together with deforestation, fires and more frequent draughts it is a first step towards an ecological tipping point where our rainforests could turn into savannahs.

Often rainforests are described as our lungs, as they remove carbon dioxide from the atmosphere and produce oxygen and keep our atmosphere in balance by doing so. Recently NASA found that the Amazon inhales more CO2 than it emits and the forest therefore reduces global warming. However, when dying the forests releases CO2 into the atmosphere, which is estimated to be 1.9 billion tons each year.

Deforestation and fires to clear forest for farmland has already changed the regional climate drastically in terms of rainfall patterns and distribution.
Furthermore, the climatic phenomenon of the El Nino Southern Oscillation is associated with dry conditions in Brazil and the northern Amazon and its frequency increased in the past years and is expected to further increase in the future.

This is a drastic change for nature and for humans as we rely on these forests to somehow keep our atmosphere in balance.
The rainforest stores an equivalent of about 15 years of human-caused emissions in its soil and biomass and a massive die-back could greatly accelerate climate change. About 2 billion tons of CO2 are taken out of the air each year by the rainforests photosynthesis, however, during draughts in 2005 and 2010 this process reversed with 3 billion tons of CO2 emitted by the Amazon. This caused a net 5 billion ton increase in CO2 to the atmosphere.
Our changing climate, fires and more frequent draughts in change with sudden floods are pushing the Amazon to a tipping point and we are closer than you would think, with large areas dying or being already dead. If we loose the rainforest, the climate will change drastically and nature will never be the same, as we know it now.

The A-factor

I just stumbled over a detailed media report about the Russian Akademik Shokalskiy that recently had to be rescued out of Antarctica’s sea ice, and have been reminded about our excursion to the continent.

Although I do agree that a lot went wrong on their expedition, and human failures played an important role, it has also be admitted that you simply can’t change the A-factor and you need to adapt to it as much as possible.

The A-factor simply stands for the Antarctic-factor and is a common saying under Antarctic expeditioners as the climate is so unpredictable and weather conditions can change quickly. Continue reading “The A-factor”

First days on the Antarctic continent

By Bianca,

After our arrival near Davis station we got flown out by a helicopter to catch our plane to Mawson. The Aurora can only park in the sea ice, around 3-4 km away from Davis station and usually people just walk over the sea ice. However, due to the delay we already had, people who weren’t staying at Davis got rushed out,

to fly 2,5 hours to Mawson. One of the reasons was the fantastic weather we have had these days, with a blue, sunny sky and almost no wind. Arrived at the station we got loaded with work, which was a sudden change to the lazy and relaxed life on the Aurora. After some more information and briefings we got our equipment and started our overnight field and survival training on the next day. We mainly got trained on how to survive in case of a sudden weather change and the risk of getting lost. Under really bad conditions you can miss your team colleague or the hut even when it’s just 20m beside you and finding shelter, without falling into a crevasse would be your main concern. We walked over the sea ice in Mawson bay, did some mapping and GPS reading exercises, drilled into the sea ice to check the thickness, exercised whiteout conditions by finding an object walking with a pillow case on our heads and carved our bed for the night into the snow. This night was an exercise to survive in an emergency just with your survival gear (warm clothes, map, compass and GPS, ice axe, sleeping bag and bivvy) by

quickly setting up a shallow hole where you can place your bivvy. The night was rather cold (ice formed inside the bivvy) and we were all happy when we went back to the station early on the next morning.

After arriving back at the station we had some breakfast, a shower and some more sleep before we started our day. We began to organise the food for our camping trip and the field equipment that will be required (a bit more luxury than the survival night). In the evening we were lucky to get a ride in one of the Hägglund (Hagg) with the chief of the station up to one of the mountain huts. That means going up the big Antarctic plateau, all just pure ice. We got an incredible view over the plateau, mountain ranges and the sea with its icebergs, and the thought about the fact that you were standing on

almost a kilometre of pure ice was, and still is, just unbelievable. After a couple of hours and a tea in the hut, we went back to the Hagg to go somewhere else…and learned why you have to be prepared for everything here in Antarctica. The Hagg didn’t start for any obvious reason and could not be fixed. Meanwhile the katabatic winds started to blow and within five minutes conditions changed from beautifully calm and mild to windy and freezing. Considering weather conditions and time (by then it was 9.30pm) the decision was made to stay in the hut.

Fortunately, it was a surprisingly comfortable night, with a real bed, a little kitchen and plenty of food (all kinds of food, as everything survives in the cold). On the next morning, after the loss of one of the Hagg doors due to the very strong katabatic wind and some more hours of trying to fix the Hagg we were successfully on our way back to the station.

On the following day we decided not to go anywhere, with the hope to finally sleep in our bed at the station. The weather has been really good again, although we had strong winds. Tomorrow we are likely to start our field work, if the weather doesn’t change we will fly out to set camp at Richardson Lake in Enderby Land and to set up our GPS stations (previous blog post).

Icebreaker versus sea ice

More than a week after the estimated arrival time we are still fighting our way through Antarctica’s very thick sea ice.

With ice conditions as tough as it can get (10 out of 10) our progress was more than slow and the outlook of arrival had been uncertain for a long time. New rumours started to spread daily, including that we would have to turn around and go back. Fortunately, that didn’t happen and by now we are close to Davis and actually just got told that we are likely to arrive tonight. Continue reading “Icebreaker versus sea ice”

Life on the Southern Ocean

We are now somewhere around 60 degrees South, heading along Antarctica’s sea ice coastline until we will start breaking through the ice somewhere near Davis station.

We started our journey on the Aurora Australis last Tuesday, already with a two hour delay, due to cargo, and a further delay has occurred due to strong westerly winds. As soon as we left the protecting shores of Tasmania we quickly learned what’s lying in front of us: the forties and fifties of the Southern Ocean, famous for their roughness. Out on the open ocean we immediately hit a stormy sea with swells up to 6 meters. Good thing we all went to bed and our bodies could get used to it during a night sleep. The next day things didn’t seem too bad.

That however only lasted for a day until we hit another stormy weather front with waves up to 12 meters. That afternoon many of us didn’t feel too good and I think I figured out why. If the ship rolls left to right, which is quite normal, everything is fine. As soon as it starts rolling in all directions, i.e. forwards and backwards and up and down, that’s where you find most people in bed… Continue reading “Life on the Southern Ocean”

By the time you read this post I will be already in Hobart to start my days early at 8.30am with some special training. Training to prepare us for life in one of the roughest places on Earth – Antarctica.

Despite spring slowly coming upon us, temperature will be well below freezing and weather conditions can change quickly from a blue sky to wipe-out conditions. All that and more is what we will be trained for at the Australian Antarctic Division in Kingston, Tasmania. Continue reading “And so the adventure begins…”

Chasing Ice

chasingBy Bianca

If you don’t believe in climate change, that’s okay. If you don’t believe scientists that climate change is real, that is okay too. But surely you will trust your own eyes…or will you?

That is how it begun for James Balog, an environmental photographer who started an assignment for National Geographic. Despite the fact that he has been sceptic about climate change, Balog committed to the task of capture images of our retreating glaciers and realised that the ice is disappearing at a breathtaking rate.

Chasing ice captures images you wouldn’t believe, if you hadn’t just seen it with your own eyes. The observations that have been made are a fact, simply observed by cameras, and reveal that the changes in our glaciers are tremendous. Continue reading “Chasing Ice”
