Polar expedition AeN JC3 – day 4: let the science begin! Mar 15 2022

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

Day 4 · 22 February 2022 (part II)

18:14 on the bridge on deck 8. Some metres south of the 76th degree of latitude. People stand by the window, they are staring outside. Outside it’s dark. What are they looking for? What’s happening?

The activities for which we are doing this expedition have finally started. What activities do you realise on a scientific cruise? Collecting samples and data. For yourself and for others.

1 – Seaglider recovery

The very first activity is the recovery of a seaglider, an Autonomous Underwater Vehicle (AUV). It sends its position but still you have to locate it with your own eyes so that the icebreaker Kronprins Haakon can approach it. The recovery is much faster than excepted, already 15 minutes later the glider is on board. Anyhow it takes much more time to deactivate it, clean it thoroughly and most of all to dismantle it so that it fits into its huge plastic boxing that looks like an alien coffin.

To be honest, I don’t know for how long the glider drifted through the Barents Sea until we pulled it up. I don’t know neither what it measured and who will process this data. There is so much happening on this cruise that I do not manage to keep track of everything.

2 – CTD and water samples

There are a lot of abbreviations used on this cruise. One of them you hear frequently is “CTD”, which stands for conductivity, temperature, depth. A CTD is an electronic device that measures these three parameters constantly while it is winched down and up again. The conductivity is used to calculate the salinity, the relative amount of dissolved salt in the water. I will not go into details in this article because I’m not a scientist and I don’t want to write nonsense.

We have to talk about two more terms: “Moon pool” and “Niskin bottles”.

A moon pool is an opening in the floor of a ship deck to have access to water from inside the ship. Where this name comes from no one could explain.

When the moonpool is opened and the winch is ready the CTD is lowered into the water of the moon pool. And then it’s time for waiting – a quite common activity on the cruise. Time for discussions or just watching.

You see this “rosette” of dark, numbered cylinders? That’s Niskin bottles, used for sampling water. They can be opened and closed remotely so that it is possible to fetch water samples from different depths. These samples are used by chemists and marine biologists for different purposes. Since the chemists do the most delicate analysis they come first. The CTD rosette of Kronprins Haakon has 24 bottles. Today 22 of this bottles are filled, each one with water from a particular depth.

3 – plankton nets

It’s half past eight, when parts of the ship’s starboard hull is moved aside. Now it’s time for the first plankton nets. Marine biologists will work till long after midnight to bring down different nets for collecting zooplankton and phytoplankton. And there are many net types with different net sizes for different purposes. I have already worked with marine biological data so I know the names as bongonet or multinet. But now I see them first time in real life and learn about the different purposes and methods. Each net has not only its own construction but needs a distinct speed for being lowered and another one for being pulled up again.

Not all plankton nets are taken from the starboard. Some are so heavy, they need the more powerful winch at the stern of the ship. One of these is the multinet, a combination of five nets for collecting plankton from different depth intervals.

The activities continued the whole night. According to the data the last one was finished at 6:31, one hour before breakfast. I however decided to go to sleep at half past twelve. It was not relevant for my work to watch every activity and I was really tired. I’m a morning lark, not a night owl.

And since this blog article is already quite long I make it optically even longer by finishing it with another photo featuring the multinet.

Polar expedition AeN JC3 – day 3 and 4: transit to P1 Mar 14 2022

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

Day 3 and 4 · 21 – 22 February 2022

Monday, 21 February

Yesterday afternoon we left Tromsø behind for the transit to P1. The program Arven etter Nansen has seven so called process study stations called P1 to P7. P1 is the southernmost station with the approx. coordinates 76° N 31°13′ E. That’s almost five degree more north then I’ve ever been in my live. And it is planned to reach P7 at 82° N later on this cruise. Will we make it?

ETA (estimated time of arrival) is set to tomorrow 8:00. So today is travel day.

After I woke up I take a short lookout on the helicopter deck before breakfast. This starts to be a personal tradition on this cruise. With -11 °C it is colder than the days before but wind is calm and the temperature feels still very moderate.

I expected that we had left the mainland far behind and would cruise through open sea. To my surprise I can see mountains and lights. Where are we!?

Internet reveals that we are just passing the island Melkøya near Hammerfest. Melkøya is illuminated by the lights of the processing plant Hammerfest LNG. Interesting!

After a rich breakfast I stand on the same deck again. Today I feel more like a cruise tourist then a data manager on a work trip. Even the photos look like beautiful but quite random pictures taken from a Hurtigruten ship.

And indeed the icebreaker Kronprins Haakon follows the very same route as the Hurtigruten ships. Aside from that we do not call any ports. (Spoiler: next port is Longyearbyen on Svalbard 18 days from now.)

The route of Kronprins Håkon from Tromsø to Hammerfest and beyond

What do you do on a transit day on sea? Participating the mandatory sea ice training for example. It’s from 9:00 to 14:00 with a lunch break and we are told a lot about the different risks we might be confronted with on this cruise.

What I know is cold weather. Hypothermia, frost bite. I tented at -35 °C, I skied in blizzard-like conditions. I guess I have a bit of experience.

What I hardly know is arctic sea ice. I’ve been on the ice of the northern Baltic Sea countless times, but that water has only the tenth of the salinity compared to the water of the Barents Sea. The sea ice is softer and the conditions are quite different.

I definitely know nothing about polar bears and a lot of the training is learning the procedures to avoid contacts. I’ll talk more about this in another blog article.

At 13:30 we meet at the quarterdeck and train the handling of throw bags. Inside the bag there is a rope attached to a hip belt. When someone breaks through the ice the rescuer can throw this bag. The person to be rescued catches the rope and can be pulled back to safety. By having a long rope it is possible to keep distance. This minimises the risk that the rescuer breaks through as well. I know this from kayak courses but I’m glad to give it some tries again. Yes, it’s me on the next photo.

At 16:00 I go on deck 3 again. It has got dark and started snowing.

Later that day the arrival time for P1 has been postponed to 19:00, eleven hours later than the ETA before. So much to the letter E in ETA ;-) It is almost impossible to plan with conditions as unsure as in the Arctic.

Tuesday, 22 February

My sis has birthday today. Hooray! Will we still have internet that I can wish her a Happy Birthday? Don’t ask me why, but we have internet in this remote place and I can send her a message.

Again I am on the helicopter deck before breakfast. Three differences to the day before: The deck is covered with snow, it is slightly warmer and no land is in sight. Finally we have left mainland Norway behind. And more and more I’m able to realise that I am really on a scientific polar expedition!

Still it will take another 11½ hours until we reach P1. I use the time to finally start working. My goal on this cruise is to understand the flow of scientific data. Where do the unique IDs come from? Where location and time? How are physical samples tied to the digital data? And can I improve these processes? I ask many stupid question to scientists to get a basic understanding.

And since I cannot ask questions for 11½ hours – I don’t want to be thrown overboard by my “victims” – I use more time to stand outside and take pictures.

Dinner 17:30. I forgot what I ate but it was delicious! For sure, because every single meal has been delicious on Kronprins Haakon.

But after dinner it is time to recover a glider. This is the first scientific activity on this cruise. Finally!

Internet is back! Mar 9 2022

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

Hello, dear blog readers!

After twelve days without the internet came back today though slow. So I’m kind of online again.

I do not even try to summarise all the extraordinary experiences I was able to make the last two weeks. I just say it was a lot! And it was awesome!

So today I just say hei and that I feel excellent! More from this scientific polar cruise with Arven etter Nansen I will tell when I’m back in Tromsø in some days.

For the stats: 3319 photos taken, 3473 lines of diary written. It will take a bit of time to sort and recap.

Stay tuned.

Short sign of life Feb 23 2022

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

We are at 76°45′ N, 31°08′ E and still have internet. Today we entered the sea ice and the ship is jerking when it cuts through.

After days with open sea and moderate temperatures between -5 °C and -8 °C it got significantly colder today. At time we have -24.9 °C (falling) with a relative wind speed of 8.2 m/s. That makes a wind chill of round about -39° C.

So, why am I alone out at the helicopter deck?

Otherwise: too much interesting stuff going on. This arctic research cruise is definitely one of the most gorgeous things I’ve ever experienced in my life!

I hardly manage to be up to date with my notes and I don’t have time to write more. And it’s dinner time, too. See you …

Sea ice field work training on the Sørbotn Feb 10 2022

Peacefully I wake up this morning. It is already light outside. WHAT? LIGHT? WHY? AND WHEN?

I check my mobile phone – the clock shows 8:01. SH**!!! At 7:45 we were supposed to meet at the Norwegian Polar Institute, at 8:00 we were supposed to leave there for a field work training on the sea ice. But not me. I have overslept!

We – that’s 5 instructors and round 20 participants of the Sea ice field work training arranged by the Norwegian Polar Institute and the Arctic University of Norway in Tromsø. I realise that my colleague M. already tried to reach me and ring back. I tell her that I will take my own car and hopefully make it to our destination with only a small delay.

Our destination – that’s Sørbotn, the southern tipp of the fjord Ramfjorden where the training will take place on the sea ice of the frozen fjord.

I manage to dress, make tea and pack in 20 minutes thanks to previous day’s preparation and a fondness for packing lists. Although I take it easy while driving (safety first!) I arrive less than 10 minutes late while the preparations are still in progress.

We are split in two groups. Our group will do measurements of ice and snow depths first and take ice core samples after lunch break. I won’t go here into details too much, because I’m a newbie to all this and I do not want to write half-understood nonsense. I’ll have to look up some details of today’s stuff later.

Although I drill holes in the ice, help calibrating the GEM2 device, measure temperatures in a freshly taken ice core and use a MagnaProbe to measure a transect of snow depths I have a lot of time to take photos, too. So, let’s just start with this.

Explaining snow depth measuring with the MagnaProbe

Being on the ice with a bunch of nice people is not only a lot of fun but it will help me in doing my job at the polar institute. Part of it is to manage scientific data. The deeper my understanding on collecting data the better I can do my work. The most interesting thing today was observing the coexistence of advanced sensor technology paired with GPS tracking and the usage of rulers, pencils and paper as in the early days of polar research.

There was one thing I wasn’t involved in: The usage of a remote-controlled underwater drone. We clearly could see some fishes and jellyfish (do you spot it on the 1st image below?) on the live display. I know that it’s used for research, but I would love to have it just as a toy.

Hopefully this was not the last time that I was involved in field work this year. And perhaps we’ll be lucky with the weather again next time. For while we had calm conditions and even sunshine, wind drove heavy snow squalls over Tromsø just some hours after we called it a day.

Four winter days in and round Obbola Jan 9 2022

OK guys, it’s Sunday afternoon and I’m too lazy to write long texts. I just show some photos of the last days where our German friend Medi joined Annika and me on various excursions with some notes.

Thursday, 6 January – skiing in Västermarks naturreservat

+++ Västermarks naturreservat, 50 km north from Umeå +++ a non-commercial forest made us climb over and under fallen trees that lay across the marked loop trail +++ by the trail a wooden cabin +++ time was too short to fire the oven but lighting candles is cozy, too +++

Friday, 7. January – lunch break skiing

+++ right next to our postbox (500 metres from our house) starts Spåret, a 3600 metre long forest trail +++ we use back-country skis to ski Spåret in my prolonged lunch break +++ we, that’s Dirk – guest for two nights – Medi and I +++ -12 °C, but my Anorak is too warm +++ I tie it round my hip +++ on the photo it looks like a skirt +++

Sun salutation Dec 31 2021

While the polar night in Tromsø started in the end of November and continues for two more weeks there is no polar light home in Obbola which is 6 degrees south of Tromsø. So if there is clear sky, then there is sun.

After Christmas in Norway Annika and I arrived in Obbola some days ago. First the weather was cloudy and stormy but today sky was quite clear. Therefore I could witness the sun today for the first time in more than a month. I only had to go 200 metres to the edge of our little bay Grundviken where I waited for the sunrise.

Thick ice floes at the icy shore of the Baltic Sea

I love sunrises and sometimes I can stand up quite early to witness it. But today it was really special to watch the sun rise higher and higher up the sky while in Tromsø polar night still continues.

After breakfast we took the car to Byviken in Obbola to join the winter bath. Round 40 cars were parked there and a queue of winter bathers waited at the ice hole. Winter bathing has really become a popular sport within the last years. We decided to avoid the queue and continued to our favourite beach at Vitskärsudden where we had to climb over a wall of ice but then we were the only winter bathers. Air: -10 °C, no wind – perfect conditions. Great!

We may take another outdoor bath today, but then in the hot water of our friend’s hot tub. I guess this bath could take slightly longer than the previous one.

A cabin named Fredly Dec 24 2021

Let me take you to my favorite place
Just a five hour drive from the city
Just follow the road until it stops
And then keep walking for another forty minutes
Then – out of nowhere – there it is
My cabin!

(Ylvis, “My cabin”)

I was lucky to get the my employer’s cabin for the Christmas week this year. The cabin of the Norwegian Polar Institute lies on a mountain slope by the fjord Kattfjorden. Two days ago Annika and I packed my car with a a lot of food and winter equipment and drove to the cabin, which is 40 km away from where I live in Tromsø. It lies by the road to Sommarøya (the summer island) which is a funny name when you drive through intense snow fall.

We did not have an address, but a small map and a description and so we found the parking place where the cabin supposed to be. And there it was, up on the hill in seemingly pathless terrain.

But under the snow there was a path up the hill and we found it. It took some efforts to bear everything up.

A Norwegian cabin can be everything from a wooden box to a luxury retreat. Our cabin has running water (cold and hot), electricity, underfloor heating, a kitchen, a bathroom with shower, a wood-burning stove, a sauna, internet and more.

We followed the manual and turned the underfloor heating to the maximum, but even after some hours the cabin was as chilly as before. We failed to fire the wood-burning stove because there were only large logs of wood and no axe.

At one o’clock in the night we woke up. Whether it was because of the gusty and stormy wind or of the cold I cannot say. 8 °C in the cabin, the same as hours before.

I put on clothes and went down the hill to look for an axe in the woodshed by the road. I didn’t find one but I found bags with smaller pieces of wood. I hefted one up (exhausting!) and finally was able to make a fire. We were awake for an hour, sitting by the oven, gladly watching the thermometer showing the rising temperature.

Right now it’s icy cold
But in sixteen hours, it’s gonna be hot!

(Ylvis, “My cabin”)

The next day I slept until 10 o’clock. It was still dark and Annika and I took breakfast. One hour later it was bright enough to see the falling snow. We put on our clothes and went to the fjord Kattfjorden, which is less than 100 metres away from the cabin – and 20 metres in altitude.

We looked at the rocky coast and the seaweed covered stones and decided not to winter bath here today. Soon we trudged uphills through the snow back to the cabin and took it easy for the rest of the day. I can say, that the short days in the time of the polar night can be really relaxing.

At 13:00 the sky started to clear up and the snowy mountain ranges glowed colourfully. Polar night does not mean that it is pitch black 24 hours a day.

How lucky we are, we who may be here and stay for Christmas. In the cabin named Fredly (peaceful shelter).

Tromsøya crossing in winter Dec 12 2021

An almost true story to be read out loud with a deep and rough voice.

I survived one of mankind’s largest expeditions of our times – the crossing of the arctic island Tromsøya from south to north! Probably I’m the first one, who dared to face this extraordinary challenge.

The arctic ice breaker could not approach the harsh coastal line of Tromsøya’s southern tip. Too mighty the storm, too sharp the rocky cliffs, too high the enormous waves! I was forced to row the last mile in a wooden dinghy. When I approached land I realised that despite of months of planning I was without food! Would I survive? Well, the tour must start, with or without provisions. One has to go on in live.

The land was wild and it was hard to find the entry point of my expedition. Where is Sydspissen, the Southern tipp? With my extraordinary orientation skills I finally managed to find this unexplored promontory which would be the starting point for my crossing.

I followed the coastal line through a field of invincible rocks. The storm howled and the surge of waves covered everything in spray. I decided to leave the exposed coast and seek shelter in the inland. To my surprise I found some ancient dwellings.

It seemed that this hostile island had been inhabited earlier. What a discovery! I continued my way and realised that I was not alone. People still seemed to live here. While most of the indigenes hid inside some dared to be outside, guarded by their dogs. The houses were shocking. While the people seemed to have some basic skills in woodcraft, they still lacked the knowledge of constructing right angles.

I continued my way through the forbidding terrain. After a while it opened and gave view to an extent of ice. Could it be a lake? Probably it had been frozen for centuries. Here I spotted more locals. As the others before they ignored me. Didn’t they dare to seek contact? I do not know. First I though they would hunt seal or walrus but they just seemed to wander around without any goal.

Soon I was alone again in the rough mountain scape of this arctic island. Orientation was extremely difficult. Without my compass and sextant I probably would have been lost forever in this pathless country. I was completely on my own.

The terrain descended and gave view to a strange installation. Scaffoldings pointing up to the sky were erected randomly on that slope. Was is temples or other places of worship? Who build them? When? And why? Probably one never will find out.

Since I lost my food I was forced to continue my expedition. Time was precious. The land was bleak and barren. No trees, no bushes, nothing. Maybe some moss seeking shelter between the stone could survive under the eternal snow. For other plants this place is too hostile.

The mountains became even higher and I got view on a small coastal village, probably abandoned ages ago. One wooden house lay nearby but it lacked a door and most of the walls.

I looked for walkable paths that would lead me further north. The more north I came the more glaciers covered the land.

It started to get dark but without food I did not dare to seek shelter. I was forced to go on and on without any rest. Amidst the mountains I spotted two indigenes. They sat on some kind of toboggan well clad in furs to keep them warm in the harsh sub-zero climate. I did not dare to disturb them and only managed to get a blurred photo as a proof of my observations.

According to my positional measurements the northern tipp of Tromsøya could not be far. I had survived until now. Would I make it to Nordspissen, the northern tip?

Alas – after more efforts and privations I managed to reach Nordspissen. I was grateful that fate allowed me to be the first human who reached this remote spot on foot. To my big surprise the legend was true: There is a mystic monument at Tromsøya’s northern tip and I can prove it:

But my efforts were in vain. I was too late! The last ship of the season just had passed by. Now I was forced to live here on this remote and solitary polar island for another year. But that’s daily routine for tough explorers like me.

Interval training in Vasstrand Dec 4 2021

Today I tried a tour on the mountain Stappen on the island Kvaløya, where I did most of my hiking tours the last months. In my book “På tur i Tromsø” it is marked as quite easy and that it would take 1½ hours up. Well, perhaps in summer …

Although sun does not rise anymore it’s already quite bright at 9 o’clock. I stop my car ride of 45 minutes to take this photo at 9:20 on the mountain passage.

At 9:50 I start my tour. No snow shoes, but spikes in case of icy patches. And a warm down jacket. And a tripod for making photos in twilight. Backpack is heavy.

First I walk along the road and then uphill through the snow. I use to manage to hike up mountains although it can take some efforts. I love to trudge through snow. The combination however is extremely exhausting since the snow today is often knee deep and especially the first part has some steep bits.

I have to rest many times and my heart is beating like a hummingbird’s. There are ski tracks but I’m wondering how to ski here where the forest is so dense. Well, while most Norwegians are excellent skiers, I’m not.

I arrive at the bog Vasstrandmyra which is described as being wet in the tour book. Now it is frozen and snowed over. It still goes up though more gently and I look for a route with as less snow as possible. Today’s destination has come into view, the mountain Stappen (570 m). It looks like having been painted by a toddler. A line up, a peak, a line down. I want to go up there but have the impression that I’ll probably not make it.

A second steeper passage through another wood lies ahead of me. I’m panting. Snow is mostly knee deep until I make a step that sends both legs completely into the white. The snow is hardly deeper but I found a mud hole well hidden under the snow. Thanks to the rubber boots I wear my feet stay dry.

With some more breaks I manage to hike up to a second plateau and start ascending the mountain.

On the photo it looks quite flat, but in reality it is steeper. That is not a problem. The problem is that there is no visible way and it is impossible to see, where there are holes between all the snowed over rocks. Quite cautious I hike up a bit but after 60 metres I realise that this kind of testing each step takes too much time.

I rest sitting in the snow with hood on, because it has become quite windy which makes the frost temperatures feel much colder. I even witness a larger snow devil – a mini-tornado sucking up snow – just some ten metres from me and can feel the snow dust in my face.

Although I do not have a 360° panoramic view I cannot complain. The mountainous landscape in the warm colours of polar night’s noon is just beautiful!

I do not rest long, then I start my descend. As soon as I reach the plateau hiking becomes easy. Trudging through snow downhills is much faster and even on the not-so-steep bog my step length is 50% larger than on the way up. A snow grouse flees, it does not want to be photographed. It’s windy and snowy and wintry and an exhausting but an awesome tour.

Round one o’clock I arrive at the car glad about the car’s heating and a warm sweater.

On my way back I stop at the supermarket and delicacy shop Eidehandel where I eat some warm lunch. At 14:30 I’m almost home but I have to stop for another photo because now it has become dark. Not pitch black, but dark enough to see the stars.
