Arctic Ocean 2023 I – starting the cruise Jun 2 2023

This article is part of the series “2023-06: Arctic Ocean cruise KPH”.

1. June – day one

Yesterday I had arrived in Longyearbyen on the Svalbard archipelago, today the cruise Arctic Ocean 2023 I will start. Our ship is the research ice breaker Kronprins Haakon, that I know from last year. It has anchored outside the quay so we are fetched by boat.

On the way to the ship we sit outside. When we arrive at Kronprins Haakon we go into the small boat cabin because the whole boat is winched up by crane until we are on level of deck 4. Time to check in. I get the very same cabin as last year and will share it with a student from India.

Time to say hello to the “Heli deck”, where I spent many hours last winter.

Shortly later I have the opportunity to get a single cabin. According to the cabin list I am a sailor now. Didn’t know that! It’s cabin 468 if you want drop by.

We take lunch at 11:30 and get a safety briefing at 13:00.

Two hours later the anchors are raised and we start our cruise. In the huge Isfjorden mountain chains are everywhere. It’s very impressive. Less the photos of the mountains but the feeling standing there on deck in the sun and have this gorgeous view in all directions while the seagull circle the ship.

2. June – day two

The original plan was to reach station 01 at 84.5° N 18.8° E but the ice situation makes it quite unlikely that we will reach this station. The previous cruise wanted to reach 82.5° N and gave up at 81° N. We’ll try to reach station 05 that is still at almost 84° N. We’ll see, what happens. Travelling in the Arctic is still unpredictable.

While the main research work will take place at the stations that we reach in a couple of days, Ingeborg who amongst others works with microplastics wants to deploy a “neuston-catamaran” that contains two nets collecting microplastic (and other stuff that is large enough). This catamaran will be pulled at the ship’s starboard before brought back on deck again. And since it takes some time, Ingeborg can deploy a buoy for a Finnish colleague by just throwing it into the sea. Then the catamaran is pulled up and the nets look quite dirty.

It’s algae that has been caught together with the plastic and it is so much, that it would take ages to dissolve it without changing the plastics to measure. So this sampling was unfortunately in vain. But there are other scientists on boards. One of them is Malin who works with zooplankton. She takes the samples and looks for species. And finds a lot of Calanus finmarchicus, a common copepod in the north. We can observe it through the microscope.

Checking the sample – does not look promising

While we are standing in the “wet lab” I see, that we soon will reach the ice edge and enter the ice. I leave the lab, grab my camera and my down parka (it’s -5 °C) and take pictures from the observation deck while we leave the open water behind.

While the ship tries to find the best way through the ice to save time and fuel now ice is mostly present. And then, after the evening meeting there comes a loudspeaker announcement: Polar bear at the port side. We see it on the starboard side but it’s quite far away. Anyhow, a photo for the records (600 mm, no crop):

Where we are? Halfway between Svalbard and Greenland. After heading mostly west since yesterday now we changed course and head north. Way up north.

Arctic Ocean 2023 – prelude May 31 2023

This article is part of the series “2023-06: Arctic Ocean cruise KPH”.

When it looks like this on my table …

… then I’m going to travel. I love packing lists and I need them so that I do not forget too much.

At 9 o’clock everything is packed (ca. 50 kilos!). At 10 o’clock the taxi fetches me and takes me to the airport in Tromsø. Two and a half hours we are in the air heading north.

It’s very cloudy but shortly before landing I finally can see something different than sky and clouds: Svalbard’s main island Spitsbergen.

Soon we will land in Longyearbyen, where I landed three month before. But there are some differences.

Last time I travelled with Annika and we went on vacation before I worked in Longyearbyen for a week. Now I’m travelling with some colleagues from the Norwegian Polar Institute. Shortly before we land on the airport I take a snapshot:

Kronprins Haakon in Longyearbyen from above

There it is: the vessel Kronprins Haakon which is more or less the reason why some colleagues of mine and I travelled north: Tomorrow we will go on board on this ice breaker and start an expedition way up north into the sea ice. For three weeks we will live and work on Kronprins Haakon and I’m so excited that I may be part of this.

Today I had some hours in Longyearbyen. I was quite curious how it would look like in late spring. According to a researcher there is a lot of snow for the season this year. But on sea level the snow has melted away and everything looks soaking wet and muddy. While Svalbard reindeer are probably happy I definitely prefer winter.

If everything goes according plan we will leave Longyearbyen tomorrow at lunch time. I guess it won’t be long until we do not have any regular internet. So probably I will not blog anything about this scientific cruise before I’m back in civilisation.

Bye bye – ha det bra!

P.S.: On Facebook a friend wrote to me: “You must have the best job in the world!”. My answer – short but genuine: “Yes!”

Taking orthophotos on Kvaløya May 15 2023

That’s me, nine days ago, near a parking place by the lake Finnvikvatnet on the island Kvaløya.

I just got a drone from the Norwegian Polar Institute, a DJI Mavic Pro 2. Since it is forbidden to fly a drone in Tromsø (too near to the airport) I chose a place on Kvaløya to check out the drone and practise a bit.

What you may expect from drone flying is photos like this:

What I actually did that day was taking a bunch of photos like these:

Back at home let the computer do some heavy work. That’s the result:

What I wanted to achieve is creating a so-called orthophoto. That is a stitched image that also contains geographical information. You need quite a lot of photos to get good results. In the map above it is only 9 photos and 11 photos in two distinct groups.

I used two softwares: First OpenDroneMap to create the orthophoto and then QGIS, an open source Geographic Information System, to present the orthophoto in a geographical context.

This afternoon I took a trip to Kvaløya again, this time to the way to Sommarøya and stopped by the lake Kattfjordvatnet. Here I pulled up the drone to an altitude of 80 metres and tried to navigate a rectangular zig-zag pattern with a lot of overlapping between the images. Beside of the fact, that the images are underexposed (and I was too lazy to correct them) I’m quite content with the result. The first image is an oblique shot, the second image is an orthophoto calculated from about 80 images and then placed into QGIS.

Today’s orthophoto from the eastern part of Kattfjordvatnet

Plan for the next two weeks: getting more practise!

Kronprins Haakon in between May 11 2023

Yesterday

Yesterday I took the car to the northern tipp of Tromsøya to get my tyres changes. When I drove back I had my studded “Nokian Hakkapeliitta 9” tyres in the car’s back and brand new summer tyres on the rims. On my way back I passed the port and there lay the ice breaker Kronprins Haakon.

I continued to the shopping mall Jekta to fetch a photo collage printed on a hard foam board. The photo show scenes from the expedition I joined last year with the very same icebreaker Kronprins Haakon (KPH or even KH for the lazy ones). At time it stands on my dresser. With 75×50 cm it’s larger than expected.

Today

Today I took the car to the port, parked it outside, went to kai 25 and went on board of Kronprins Haakon. Not to join a cruise but to meet my colleague M. on the bridge. Nice to be there anyhow. M. already had installed some GIS software plugins on a computer there. I configured another plugin on my computers that can show the ship’s position in realtime together with other map layers.

In three weeks

The ship’s position in realtime however works only when my computer is connected to KPH’s network. No use to have it home. But in three weeks I’ll enter the vessel again, then in Longyearbyen. Then I’ll join my second arctic cruise with the Norwegian Polar Institute that will lead us to the Arctic Ocean north of Svalbard. There’s a lot to do and I’m nervous because I have some tasks there that I never did before but I’m looking forward to it very much.

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!

Farewell, Longyearbyen Mar 20 2023

This article is part of the series “2023-03: Svalbard”.

I am sitting in the waiting hall of Longyear Airport, waiting for my plane to Tromsø.

More than two weeks I’ve been here, first on vacation with Annika, then working for the Norwegian Polar Institute at UNIS, the University Centre in Svalbard.

I worked with Luke, data manager for the Nansen Legacy and had a guest office on the other side of his office in the biology section.

While my office may look totally normal, the view definitely wasn’t.

Some days at 9 o’clock I went to other side of the building to the Longyearbyen section of the Norwegian Polar Institute to have coffee break with my colleagues there.

Coffee corner, Norwegian Polar Institute, Longyearbyen

In Longyearbyen you put out your outdoor shoes before you enter a building (with some exceptions as the local COOP grocery shop). And so it is at UNIS. You can clearly see by the shelfs whether people are at home or at UNIS.

Soon I will travel back to Tromsø and I’m looking forward being back. It was a fantastic experience to spend much time in Longyearbyen. Anyhow as a visitor you also realise the limitations as for example not being able to leave the town without valid rifle permit because of the polar bears.

Continental Europe – here I come.

After work snowmobile tour Mar 14 2023

This article is part of the series “2023-03: Svalbard”.

This week I’m working at UNIS, the university centre in Svalbard together with friend and colleague Luke Mardsen. He is data manager for The Nansen Legacy. This week we collaborate on some of the software he wrote for this research project. Interesting stuff, but maybe not for this blog.

Today Luke invited me to an after work snowmobile trip up the glacier Longyearbreen. I borrowed a helmet, ski goggles and warm mittens from the Norwegian Polar Institute whose colleagues I had coffee break with today. Then I dressed like being in the high Arctic, but hey, I am in the high Arctic. Luke picked me up from the UNIS Guesthouse and then we started the tour. Luke was driving the snowmobile, I was sitting behind him. First through town, under the water pipes – duck! – and past Huset, where Annika and I had food ten days ago. Then we ascended the valley and then the glacier. Today we have had the finest whether thinkable: crisp, clear, blue sky and so we got to see the beauty of the sunset colours on the snowy mountains around as well as on the other side of the Adventdalen.

But beside of marvelling the beauty of nature there were other attractions waiting. Another ice cave, probably larger than that Annika and I visited a week ago and a bit more need of climbing. We got a tip of a colleague of Luke to visit a side room and it was astonishing. A large and high, beautiful room with a roof covered with large feather-like ice plates. I never saw something like this before. Without torches it was pitch black in the cave and so photographing took more time and efforts. I managed to take some snapshots anyhow.

After some exploring we returned and climbed up the ladders to the cave entrance. Now the blue hour had started and the light was less colourful but equally beautiful.

On the Longyearbreen in the blue hour of the evening

Back we went on Luke’s snowmobile. He in the front, I in the back. It was only two hours later when we arrived at the guesthouse again, but I had completely fallen out of time, especially in the ice cave.

I lack the words to thank you for this wonderful after work trip, Luke. See you tomorrow in the office.

Summer travel plans Feb 10 2023

This article is part of the series “2023-06: Arctic Ocean cruise KPH”.

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!

Anticipation is the greatest joy Jan 18 2023

This article is part of the series “2023-03: Svalbard”.

In Germany this means “Vorfreude ist die schönste Freude”. I never liked this proverb. I’m too impatient! Or is it true? Even for impatient people like me? Perhaps.

Yesterday I asked the map section of the Norwegian Polar Institute if I may have a map of Svalbard. And I got one. Since my part of our shared office does not have any walls I decided to put in on the wall in my Hybel – my small apartment in Tromsø. Here it hangs, just between the two windows.

Last week I got to know, that I may collaborate with L. for a week. He does not work at the Polar Institute, but at UNIS, the university centre in Svalbard.

Today my boss told me – he knows me well – that I may work there. So, If L. and I really find a common time to work together and there is accommodation and payable flights, I’ll be in Longyearbyen within the next months for a week. Plus some extra days when possible.

I have been in Longyearbyen before, but only a couple of hours after last years expedition. It would be so great to travel there again with much more time.

Of course it’s not carved in stone yet, but I’m looking forward to it already very much.

Anticipation is the greatest joy.

From Tromsø to Obbola Nov 21 2022

Friday, 18 November – walking back from work

It’s weekend. Today I stopped working already at 14:15. Sunset was 40 minutes ago and the light is beautiful while I’m walking home.

In Tromsø there’s hardly any snow, but a lot of rime. In the evening there’s polar light, but I only take a smartphone snapshot – tomorrow is a long day.

Saturday, 19 November – taking the bus to Narvik

Today is travel day. Round 16–17 hours it will take me from home to home.

Yes, I have two homes. One “work home” in Tromsø where I work and one “Home home” in Obbola where my wife Annika and I have a house by the Baltic Sea.

The weather is gorgeous and I take many photos through the window of the bus. Therefore some of the motives are blurred. The last one – the large bridge Hålogalandsbron is jittery because it has become dusky.

Saturday, 19 November – taking the train to Umeå

It’s a long ride from Narvik to Umeå. Departure 15:10, arrival 1:40 in the night. But it is a though train. I don’t have anything more to do but being awake on the arrival in Umeå. While I eat my take-away sushi outside of the train station it gets dark and so there is not much to see from the landscape in the train unless it stops.

Bastuträsk station (from the inside of the train)

In the frosty inland where it is quite cold I witness a special phenomenon. The whole forest we are passing is lit in green light. Another aurora? No, it’s cloudy. There are passages where the power lines for the train are coated with rime ice. The layer is so thick, that the current collector of the train looses contact and the electricity jumps over emitting bright green light that illuminates the dark forest.

Green light from the train’s current collector

The train arrives in Umeå in time and Annika already waits at the station. Another half an hour and I’m home home. Bed is waiting!

Sunday, 20 November – winter feelings

Oh, what a blessing it is to be home home. Normally we are supposed to work at the offices of the Norwegian Polar Institute but my boss knows about our long-distance relationship (or is it called long-distance marriage?) and allowed me to do home office until Christmas. Tusen takk! And it is even wintry and a bit sunny and a bit snowy.

From now on I can enjoy the view from my home office.

The terrace and the window of my home office

Monday, 21 November – the first home office day

Enjoying the view from my home office is a pleasure but when all of the sudden the morning sun peeks through the clouds I just have to go outside and make some photos!

And what do I do at lunchtime? This:
