Arctic preparations Apr 29 2023

Have a look at these two images. They have something in common.

Both are related to my participation in the Arctic Ocean cruise in June. After the Nansen legacy cruise last year this will be my second scientific cruise to the Arctic with the Norwegian Polar Institute. And this time I’ve got extra tasks.

1. Drone flying

A scientist asked if I could fly a drone to map the ice stations. I didn’t have any experience in drone flying so I bought a private one to practise some weeks ago. In addition to that I made the Norwegian online course in drones (class A1 and A3) and the exam. Now I’m registered as a drone pilot in Norway, both in private and for the Norwegian Polar Institute. That was the easy part.

The interesting part starts when I shall take photos with latitude and longitude information from a drifting ice floe. But I’m not there yet (and quite happy that I have another month of preparation).

The drone photo above was taken in Norway. In Sweden it is a lot of paperwork to get permission for the publication of photos, especially when they show the sea as well. In Norway this is not the case, as long as you know the legal rules and restrictions.

2. Ice chart and weather info

To help both the cruise leader and the crew with planning it will be my job to provide them with current information. That’s ice charts coming from a SAR satellite and weather forecasts for e.g. wind, temperature and pressure. The data will be presented using the Open Source Geographic Information System QGIS. The screenshot above is just from a small learning session where I loaded in quite unrelated data as a topographical map of Svalbard, an ice chart from two days ago and current wind information.

The interesting thing will begin when we head north, leaving Svalbard behind. Then we do not have internet access anymore except sending and receiving emails through the slow and expensive Iridium network. So I cannot use all the cool QGIS plugins to gather data directly but I’ll have to send data requests per email and then receive the data later. This will be both interesting and challenging. I’m somewhere in the middle of being quite excited and pretty nervous.

Anyhow I wanted to have jobs and tasks and I’m glad I get the opportunity in a more active role than last year, were I was more like an observer. I guess, I’ll learn a lot.

Arctic Ocean, soon I’ll come!

A day cruise to Finland Apr 7 2023

A day cruise from Sweden to Finland and back.

Holmsund—Vaasa: 11:15–16:00. Vaasa—Holmsund: 16:30—19:00. The ferry is not faster on the way back but the Finnish time is one hour ahead.

Just some photos:

What a wonderful vårvinter kayak tour! Apr 5 2023

Yesterday the weather was calm and sunny. A perfect day for kayaking! Perhaps to Vitskärsudden, our favourite beach?

Chapter one – Bredskär

Kayaking needs a bit of preparation, especially in winter. After we have fixed a problem with Annika’s rudder, dressed ourself and went over the ice to the northern tip of the islet Lillskär we are ready to start our tour.

Olaf ready for departure (Photo: Annika Kramer)

Annika goes first, I follow. We turn left and paddle along the edge of the ice.

Sometimes we cross fields with crushed ice. Many of the ice slices are thin and in the waves they sound like tuned bells.

We paddle along the island Bredskär. The waves are shallow and there is hardly and wind. I have to make a short stop to take a picture of the “ice monster”, then I follow Annika to the sandy bay in the northeast of the island.

Paddling over clear water and sandy ground

We continue following the coastal line until we come to Bredskärssund, the sound between Bredskär and Obbola. As expected the sound is covered with ice and we have to return.

Time for …

Chapter two – Vitskärsudden

Slowly we paddle back enjoying the exceptionally beautiful weather and the ease of movement. Leaving Bredskär behind we cross the water heading for the rock that marks the entry to Vitskärsudden.

Arriving there more ice fields wait for us. Here are many layers of thin ice and it is not easy to find gaps to put the paddle in. Often it just glides and slides away.

It is not possible to paddle into the bay. It is covered with ice floes, many of them thick and large. But we do not want return home – too beautiful the day – and decide to paddle to the islands Obbolstenarna where we shortly have been two days ago.

Chapter three – Obbolstenarna

The way there is easy. No mentionable wind, just open water. In front of the islands there is another ice field, but it is small and easy to cross.

The next ice field is thicker. We try to break through but decide to go round. We just follow the coastal line.

In the south we go round an ice cap. According to the nautical map there is no island, just a shallow with some rocks.

Again I take a small detour to take a photo. This time to a large ice block.

Then we paddle north. First along the islands …

… then …

Chapter four – Home

we are leaving Obbolstenarna behind and head home. We enjoy the effortlessness of our today’s kayaking but we got a bit hungry. 10–15 minutes later we stand on the ice near our house.

We take a tour selfie then we drag our kayaks back home. First over the ice, then through the snow.

Thanks for the fabulously beautiful tour, Annika!

Annika tracked the tour with her smart watch. Here’s a small map. I added some names.

Summer travel plans Feb 10 2023

Today I got the final commitment of my boss, that I will participate the “Arctic Ocean Cruise 1” this year. It will be my second polar expedition with the Norwegian Polar Institute on the research icebreaker Kronprins Haakon. This time not in winter but in June when the sun never sets.

Planning has just begun, so there is not much more to tell. At least there is a first plan about where the expedition will head, if the ice conditions allow.

I’m both happy and very grateful to get such an extraordinary opportunity this year again. What a great job I have!

ℹ︎ This is an updated version of the original post, since I realised that I got more information by email.

Polar expedition AeN JC3 – day 17 and 18: An incredibly beautiful day on the ice Mar 23 2022

This article is part of the series “2022-02: Winter cruise KPH”.

Day 17 and a bit of 18 · 7 and 8 March 2022

7 March

We have arrived at a place somewhere between Svalbard’s second largest island Nordaustlandet (14.443 km²) and the easternmost island Kvitøya (682 km²). No one lives permanently on these islands.

The ice experts have found an ice flow and examined it. The ice near the ship has some holes so the dress code is survival suits for the first time. In opposite to the formerly used Regatta suits they have attached boots and neoprene arm and neck cuffs. They shall keep you warm and dry in case you fall into cold water – or in our case break through the ice.

I am very interested to join and observe ice coring, a missing link on this expedition. I wasamhowever quite doubtful whether I will be allowed to enter the unreliable ice on this station. But I am lucky again, I may follow M. and L. onto the ice.

Earlier I was told that I may join the scientists taking ice cores but won’t get the opportunity to take ice cores by myself. That’s understandable. To my huge surprise – and delight! – plans were changed: L. shows me how to do it once and then it’s up to me to take five more ice cores. Give me snow or ice and something to play with and I’m happy ;-).

No, I’m no experiences ice corer after five cores. But at least I get an idea and a bit of a routine. In measuring snow depths, ice depths, the freeboard and writing down the values with a pencil. In mounting the large ice core attachment onto the electric drill and removing it after coring. In putting the ice core onto the gutter-shaped cutting board without flooding the electric drill or touching the snow (happened once – sorry!). While M. is cutting the core into slices and putting them into wide-necked plastic bottles I continue with my work. And I have to continue, because I’m still slow and M. shall not wait too long. I think, I could do that for weeks. Standing on the ice and drill cores out of the sea ice.

I have asked Pernille to take some photos from me while coring. These are probably the only photos that prove that I actually did something on the expedition beside of taking photos.

Photo credit: Pernille Amdahl, Nansen Legacy –tusen takk!

And the afternoon? I am allowed just to go onto the ice once more as long as I find some team lead to join. I find one and so get my 7th opportunity on this cruise. Two and a half more hours on the ice. I overhear a radio message. No polar bear warning but the information that our ice flow drifts with more than 2 km/h and the water depth is decreasing. This could damage instruments when they are too deep in the water.

Just some more photos:

A tent, a ship, the sun and Arctic sea ice

And later, when we are on the ship again another polar bear approaches. This time it is a curious one that is very interested in the scientist’s equipment. And since it could harm the bear when it eats cables or plastic it is shooed away with a flare gun. **BANG**. It gallops some metres and then walks away. No polar bears were harmed and as far as I know no cables.

By the way – it was a good decision to use the survival suits. One of the scientists went through the ice today. All of a sudden and quite near the ship. It did not take long to pull the scientist out of the water but without the survival suit this would have been a very wet, cold and unpleasant experience.

8 March

The next day some additional measurements are done on the ice and then we leave last ice station of Arven etter Nansen JC3.

Ha det bra, Arctic sea ice. Farewell! It was a great pleasure to meet you and I definitely will miss you!

Polar expedition AeN JC3 – day 14 – 17: Travelling south Mar 23 2022

This article is part of the series “2022-02: Winter cruise KPH”.

Day 14 – 17 · 4 – 7 March 2022

4 March: after our second polar bear encounter we leave the ice station P7 at the 82th degree of latitude behind and slowly head south.

This journey will take more than two days although its only 250 km to sail. That’s because many scientific activities go on. Not from the ice but from the ship. Just an excerpt from the activity log:

CTD with water sample (19×)
Box core (4×)
Håv-trekk stasjon (2×)
Multinet (2×)

I help the benthos people in the lab and learn a lot, I discuss data matters with scientists, I edit photos. At the same time the character of this polar expedition has started to become a bit more leisure-like. A “no-talent show” is organised as well as a table tennis tournament. A quiz evening takes place and J. shows some of his favourite movies. And from time to time I stand on the helicopter deck and take new photos.

7 March: In the morning we arrive at a place between Svalbard’s second largest island Nordaustlandet and the island Kvitøya, that we already passed a week ago. Here we will have a last 24-hour ice station with the adhoc name SIce Kvitøyrenna.

Polar expedition AeN JC3 – day 13 and 14: Polar bear ahead! Mar 22 2022

This article is part of the series “2022-02: Winter cruise KPH”.

Day 13 and 14 · 3 and 4 March 2022

3. March 2022, the second ice day at P7. I have polar bear watch on the bridge at 9:30 +2h so there is some time to relax after breakfast. While I am writing my diary there is a loudspeaker announcement, the first one on this journey:

Polar bear at the front of the ship.

I grab my camera equipment including the large telephoto lens and slip into my Canada Goose clothes. The best deck at the front of the ship is the helicopter deck and there I go.

I am not alone. Ice station was about to begin so some scientists were already clad in Regatta suits. Now they stand at the rail watching. But where’s the polar bear? I cannot see it. Until I go to the rail as well and look straight down. Whoa!

It is hard to believe, but this is my very first photo of a polar bear taken in the wild. Not some blurry spot far in the distance but a polar bear less than 10 metres away – vertically. It is quite interested in the icebreaker with all these funny colourful beings that has appeared in his world.

We are only guests in the Arctic world of the Polar Bears. We are not allowed to chase them off just to do our work. We are not allowed to chase them off to prevent them from destroying scientific equipments. We humans do not matter. Only the polar bears do. But we are allowed to chase them off for two reasons:

The polar bear should not eat plastic, rubber or other materials that could harm it.
The polar bear should not learn, that it is a nice experience to visit humans and teach this to its cubs. This could result into dangerous encounters in the future.

The polar bear realises that the ship’s bow is boring and continues to Z’s tent, sniffing and licking around ther…

**BANG** – a loud noise alarms me. **BANG** again. K. has used a flare gun to shoo the polar bear away before it starts eating the equipment. The flare gun is not used to hit a target but to make a loud noise. The noise however does not frighten the bear at all and K. gives some more shots. The bear decides that this sucks and slowly continues its way over the sea ice. Even when I have started my polar bear watch on the bridge I can see it in the far distance.

When I am on the sea ice again the afternoon to help K. with the Blueye ROV I see the armed polar bear guards with other eyes. It comforts me even more, that a whole team protects us – three watches on the bridge and several guards on the ice. Polar research works only in a team.

By the way: I am allowed to steer and control the underwater vehicle. It is not easy because the ROV lags a lot and the tension in the cable doesn’t make things easier. But in the end I manage to navigate it back to the ice hole again and we get it out of the water. It has some technical issues, probably because of the cold.

In the evening I stand on the deck and look over the ice. It was become slightly colder, -26 °C and the air is crisp. Snow and ice look as if carved from marble in the sharp spotlights of the ship.

Later this night a female polar bear with a cub is spotted. And another single bear. I miss them, exactly as I missed the walrus encounters and that of the rare bowhead whale. What this ship misses is some kind of messaging system that informs you in these cases. You cannot be everywhere and you have to sleep sometimes.

The next day I help A. and B. in the benthos lab again. When I go to the locker room to get rid of my boots for lunch I meet E., who is putting on the Regatta suit. Why that? E. tells my another polar bear has been spotted, a kilometre away.

Shortly later we stand on the helicopter deck again and watch the other polar bear approaching. This time I see it when it is still pretty far away, but it discovers our ship and comes nearer and nearer and nearer.

This bear however is less interested in us and just passes by. Good for him and less noisy for us, no flare gun involved this time.

Polar expedition AeN JC3 – day 12: ice station on the Arctic Ocean Mar 21 2022

This article is part of the series “2022-02: Winter cruise KPH”.

Day 12 · 2 March 2022

Yesterday we arrived at P7, the northernmost transect station on this cruise. Here, a bit north of the 82th degree of latitude and round about 3400 metres above the seabed of the Arctic Ocean we will start our second ice station today.

The morning I start with two polar bear watches. It snows and the visibility is not the best but still good enough to watch out for polar bears.

This is my workplace for 2×1 hour this morning:

And this is the workspace for some of the scientists:

After lunch I get another opportunity to join researchers on the sea ice.

The snowmobile is used to transport people and equipment

I join Z. again and help her erecting the tent over the already existing ice hole. Then A. uses the hole – now in the tent – to test his ROV (short for remotely operated underwater vehicle). After that Z. continues with MMS measurements. I want to help her but J. who joined our team as well will do that. Z. says that I shall take photos, she never has time for that. Well, when I get a carte blanche to take pictures I use it!

Taking photos in the tent however is not easy. It is quite dark and there is a lot of moisture that my Nikon does not like at all. But here it’s not the technical quality but the motives that matter. (Says Olaf, the perfectionist who is still angry with himself that he did not made bigger efforts to get better photos.)

The tent is erected, the equipment lies still outside.

The ROV is in the water recording videos.

K., our polar bear guide looks quite impressive standing upright on the nearby ice ridge in front of a purple sky. And the sky is purple. In the Arctic winter it is the sun that colorises the landscape and blends purple and orange of clouds and sky with blue and turquoise of the ice to always new colour palettes.

K. gives my clearance to walk around a bit. To the ice ridge and 30 metres on the snowmobile track to the ship. I enjoy my gained freedom and take some photos of the ship, the sun, the ice, of K. driving snowmobile. And it is such a beautiful day!

More than two hours I am on the ice before we return to the ship. But before that I have to bore you with another selfie ;-)

This selfie is for you, my friend Chris. It was Chris that surprised Annika and me with a generous gift a few years ago: A balaclava for each of us knitted by her. One of these balaclavas now has been in the high Arctic. It is one of the garments I definitely will pick again when I should have another opportunity to travel way up north! Thank you, Chris!

Will I be on the sea ice the next day again? Yes, but first there’s another story to tell. Bear that in mind ;-)

Polar expedition AeN JC3 – day 11 · transit to P7 Mar 20 2022

This article is part of the series “2022-02: Winter cruise KPH”.

Day 11 · 1 March 2022

Today is travel day. Our destination is station P7 (82° N, 30 °E), further north than Svalbard and even Franz Josef Land.

From the documentation of Nansen Legacy (Arven etter Nansen):

P7 – Located in the deeper Arctic Ocean. P7 is suitable for comparing the shallow Barents Sea with the deeper Arctic Ocean. P7 will have extensive sea ice coverage during winter, and varying sea ice cover during summer. P7 might be suitable for geological coring.

When we arrive there the sea ice is a bit thin. Therefore we continue a bit further north where we find a suitable ice floe. So, tomorrow: the second ice station of this cruise.

Some ice photos from this day:
