Polar Science

About Dan


  • I'm not a polar explorer or adventurer! I'm a scientist, a geologist, who is very lucky to be able to work in Antarctica. When I was 11 years old, I saw a short film about scientists working there, and decided that I wanted to do it too.

Svalbard

June 21 was the winter solstice in the southern hemisphere - midwinter, the shortest day of the year. At Antarctic stations, people celebrated the middle of their polar night: halfway to the welcome return of the Sun. In Canberra, it was a cold sunny winter day, and I was busy preparing to travel. Two days later, I was standing in the midnight sun in the high arctic: the islands of Svalbard far to the north of Norway. Here, the Sun won't set below the horizon until September.

I've come to the arctic for two reasons: in August, I'll be doing some geology field work in southern Greenland, a joint project between Swedish and Australian scientists. But before that, I've taken some time away from university work. What does a polar scientist do with his holidays? You won't find me lying on a tropical beach! I'll spend five weeks leading small tourist groups around these arctic islands, working on an old sailing ship, the Noorderlicht.

Like writing this blog, taking tourists into the arctic is a way of sharing my enthusiasm for science and nature. And at the same time, I enjoy travelling in the wilderness on an old-fashioned sailing ship.

Svalbard is a fascinating archipelago; a group of islands about 300 km long, only 1000 km from the North Pole. Half of the land area is covered by glaciers, and in winter the islands are completely surrounded by frozen ocean. In summer, vast numbers of birds come to breed here, joining the polar bears, reindeer and arctic foxes which stay all winter. The plants and animals are wonderfully adapted for life in a cold climate.

There is also an interesting human history: after the islands were discovered in 1596, they were the site of the first commercial whaling. Between 1620 and 1800, almost all the whales in the north Atlantic were killed, for the oil in their their blubber. After the whales, people hunted the Arctic Fox and Polar Bears for their beautiful fur. And in the 20th century, there were attempts to mine gold, iron, marble, coal, and other minerals, almost all of which failed. It was also visited by many arctic explorers, including several attempts to reach the north pole.

Today, there is still some coal mining, but most people come to Svalbard to see wilderness and nature, relatively untouched by civilisation. We have just finished one ten-day sailing voyage, and leave tomorrow for another. In the next posting, I'll describe some of the things we see and do along the way.

From the far north,

"Cool" Classroom Chat

Wow! Dan was just here with us at Questacon, involved in an online chat with a whole class of Year 6 students from a State School in Brisbane, Queensland.

Dan Chat

The class was the same one that was asking questions via comments on the blog, and Monica, their teacher arranged the chat for now, while Dan is back in Canberra.

We're really keen to hear back from the school about what the kids thought of the opportunity, and what they talked about after the chat. Dan had sent Monica some photos to help move along the discussion. One of them is very funny!

We captured the chat - here it is!

Dan> Good morning.

Monica> Hi Dan, Sorry we're late. The kids were a vit late getting back from sport

Dan> We're all ready at this end now too.

Veronica> Hi Dan

Emma> Hi Dan

Dan> 'morning class. How was sport?

Brendon> hey dan

Veronica> It was fun!

Emma> Fun! We did highjump!

Kirsty> fun

Courtney> it was fun

Dan> wow, there's a lot of you in the room now. Who's got the first question?

Veronica> What did you study over in Antarctica?

Emma> How many year did you have to study until you could go to Antartica

Dan> I did my first trip to Antarctica after three years at university.

Dan> I did a project there, and wrote a report about it to finish the last year of my science degree.

Erin> how many trips have u done

Justin> hi Dan

Dan> I've studied a lot of different things on my trips to Antarctica, but always some sort of geology.

Dan> I've done nine summers as a scientist, and I've also been a few times working on tourist ships.

Brendon> Have you discovered any new species of anything?

Ellie> has it been a great experience

Dan> I don't think I've seen any new species. In Antarctica, there are lots and lots of animals, but not many different species.

Dan> It's always been a great experience. Even though I've been a lot of times, it's always exciting.

Courtney> what is the lowest temperiture youve had so far?

Justin> Have you seen whales

Monica-> Survival Suit

Dan> I think the coldest was about -30°C. But the wind was also blowing then, so it felt a lot colder. We didn't work outside much; mostly we stayed in the tent.

Natalie> have you been to the Arctic before?

Shane> Have you had any frost bites

Dan> Yes, we usually see whales from the ship, on the way to and from Antarctica. Mostly Humpback and Minke whales, but sometimes also Fin whales, which are really big ones.

Dan> Yes, I also work in the arctic sometimes. I'll be going there in July and August this year.

Justin> wow

Dan> I'll go to Svalbard to work on a sailing ship, and to Greenland to do some science work. I'll be in a place called Narsarsuaq. Maybe you can find it on the map.

Shane> Is that really fashion over there

Tayla> hi

Dan> That picture is on the icebreaker, Aurora Australis, before we left Hobart.

Justin> what did you do when you were stuck in a tent.

Ellie> wow and hi dan

Dan> We had to practice using the lifeboats and survival suits, in case there was an accident.

Monica-> King Neptune

Dan> Luckily, that was the only time we had to do it!

Monica> More spectacular Dan fashion

Courtney> has there been an accident so far?

Damian> That it looks funny.

Erin> what has been the longest time you have spent in a tent?

Dan> This one is of King Neptune. On a ship, when you cross the equator, or the Antarctic Circle, he comes on board to initiate people who've never done it before.

Dan> Usually that means getting a bit dirty... kissing a fish, and having vegemite smeared on your face!

Dan> Luckily I have been before, so I didn't have to do it this time.

Tayla> how long did it take to travel from antarctica to australia ?

Taryn> hi

Damian> Did the fish turn into a prince

Sean> are you looking fored to the artic

Dan> This time, it took 12 days to get there. But it took more than three weeks to get back, because we visited two other stations on the way.

Dan> The fish didn't turn in to a prince... maybe because we didn't have a princess on board to kiss it!

Dan> Am I looking forward to the arctic? YES! I love travelling to wild places. And I've never been to Greenland before, so that will be all new and exciting.

Vanessa> i would just love to go to the places that you go to

Sean> iwould love to go to antartica

Dan> Well, there are a lot of ways to get there. You can work there, as a scientist or a mechanic, or a chef, or almost anything.

Damian> have you seen a polar bear in the wild before

Dan> If you decide that you want to go, I'm sure you will think of a way to do it.

Vanessa> my mum would just love to here about all of this i will tell her straight after scholl

Monica-> GPS site

Dan> Yes, in the arctic we often see bears. It's best to see them from the ship, because that's safer. But I carry a gun when we go walking on land, just in case. I've never had to use it yet.

Matthew> do u like goin to cold laces or warm places?

Taryn> i would love to go to antarctic and see the animals

Cody> hi dan how it gowing

Gemma> What birds do you see in the Antarctic.

Michael> hi Dan

Sean> i like playing in the snow

Dan> I like wild places, hot and cold. Ihave also worked in Papua New Guinea... also wonderful!

Monica> I've just shown them the photos of the camp toilet Dan.
Camp Toilet
(is that an Antarctic long-drop? Geoff)

Sean> was png a great place?

Dan> Where did you play in the snow, Sean? I wasn't sure how many of you Queensland kids would have seen it before.

Emily> is it cold to sit on the toilet

Christen> when you are going to the toilet has anyone ever seen you?

Sean> in new zealand and tasmania

Vanessa> it must be weird, how did it fell going in that thing or did you get the hang of it

Tayla>

Dan> Yes, it's cold to go to the toilet! So you don't waste any time there.

Dan> There's usually not any people to see you, but once I had ten penguins standing watching me!

Christen> I saw the snow in new zealand

Monica-> Christmas

Vanessa> how funny

Gemma> Hey Dan, have you ever been to Alaska? It's awsome!

Maddisyn> Hey Dan

Tayla> what do you do in ur own time

Emily R.> I been to the snow in NZ and I went skiing

Matthew> :}whats with the mr potatohead?

Michael> how was xmas

Dan> This was our Christmas tree. There were just five of us in a little hut, 500 km from the nearest people.

Emily> how long do you stay in antartica

Aaron> what did you get for christmans

Josh N> what equiptment did you use?

Sean> wow

Vanessa> it doesn't look like a big one

Dan> I got some books, and some chocolate.

Cody> cool

Aaron> what where the books about

Maddisyn> COOL

Dan> This time I was away for about four months, with about three months in Antarctica.

Vanessa> i will read about antartica and maybe it will convince me to go

Dan> My longest trip was four and a half months, and my shortest just one month.

Cody> the news paper muster been good there

Aaron> do you like travelling in big ships?

Dan> We did get a newspaper every day from Australia, by email.

Dan> Only when we were at the base, of course! Not in the tent.

Gemma> How long do you plan to stay in the Arctic for?

Bronte> what do you plan on studying in the artic

Emily> whats the difference between the artic and antartic

Monica-> Questacon Flag

Dan> Small ships are better than big ships! I like working on sailing ships best - I'll put some pictures on the blog when I'm in the arctic.

Aaron> what do you do for fun up there?

Dan> I'll be working in Greenland for about three weeks. We'll be measuring sea-level change, which tells us how the glaciers on Greenland are changing.

Sean> bye dan got to go

Dan> Differences between artcic and antarctic: Antarctica is colder, and has penguins. The arctic has less land (more sea), and bears but no penguins. There are whales and seals at both poles.

Monica> Is that something to do with global warming?

Tayla> thanks for ur time, bye

Monica> Lunch bell has gone dan. We have to lunch

Gemma> Thanks for going online and chatting to us Dan.

Cody> thanks or your time bye

Emma> Thanks for your time is been great to have a chat!! Lunch Time gotta go!

Emily R.> thanks for coming and chatting to us, bye

Aaron> bye dan and thanks

Emily> thankyou for your time. bye!

Maddisyn> Thanks heeps Dan 4 all the information about your stay in antarctica

Dan> Well, it is related. But because I'm a geologist, I usually study changes that happened thousands of years ago. But that all helps us understand what the glaciers will do as the earth gets warmer.

Christen> thanks for all the time you've spent answering questions Dan,bye

Josh N> thanks for the time typeing to us all

Dan> It was fun talking to you!

Michael> thanks a lot dan it was cool.

James> thanks dan for your time

Dan> If you have more questions, you can still send them to the blog. I'll be writing more in the next few days.

Bronte> thak you dan for you time

Monica> Thanks so much Dan. They've all gone to lunch.

Dan> I'll try to also write the blog from the arctic, so keep watching it!

Dan> What a rush! that went very fast.

Monica> It's quite a task managing 30 kids on a chat at the same time. But they did enjoy it. The room was very noisy. Good noisy.
