Polarstern in Tromsø Jul 31 2023

Last month I joined a scientific cruise on the Norwegian icebreaker Kronprins Haakon. Our plan was to reach station 01 at 84.55° N, 18.78° E north of Svalbard. But the exceptionally thick sea ice of 2 metres and more prevented this. We tried to get north but in vain, we only reached 80° N and a bit.

We were not alone. The Swedish icebreaker Oden and the German icebreaker Polarstern had the same issues. In the night from the 11 to 12 June we were quite near to the Polarstern – less than 10 nm if I remember correctly. The vessel was visible on the “OLEX” navigation screen.

After another five week expedition to the Gakkel Ridge, the Greenland Shelf and the Nansen Basin the Polarstern arrived in Tromsø today. Not at the port on the island (I guess, too many cruise ships) but in Tønsvik by the mainland. Some weeks ago I asked the Alfred Wegener Institut (AWI) if it was possible to visit the ship but it couldn’t be done this time. Anyhow I took the car after work and drove there to get at least some photos.

Hopefully I’ll get a opportunity for a visit another time. And yes – I long deeply for the Arctic when I see the Polarstern lying there or check the track in the internet.

But hiking in the Norwegian Nature always helps. Two photos from a short hiking trip after the icebreaker photos:

#escapism – midnight sun at Lyngstuva Jul 24 2023

Sunday, half past five in the afternoon. I just arrived in Breivikeidet by car, waiting for the ferry.

It was a quite spontaneous decision to take the car to the northern tipp of the Lyngen Peninsula to watch the midnight sun before the polar days are over in Northern Norway. Without the ferry I would have to drive 200 km one way, using the ferry it is less than half the distance. And there the ferry arrives.

Eight a clock. I have parked by car on a camping ground and the backpack is packed. Camera equipment, something to eat and drink, an extra jacket as well as sleeping bag and camping mat. Hopefully I can sleep in the tiny hut that is near the lighthouse I want to hike to. If not, I’ll sleep outside and get eaten by mosquitoes …

The way there is only 3 km. First I follow the broad gravel road then I turn right and hike along a path that meanders through the mountain landscape. The forecast of the Norwegian weather service yr was right: the weather is nice and mostly sunny. Hopefully it will be clear this night.

And there it is: Lyngstuva Lighthouse. The hut is tiny but it’s open and no one else is there. Nice!

Behind the lighthouse lies the open sea with the prominent shape of the island Nord-Fugløya (Northern bird island) in the north. On the sea there are surprisingly many ships, some of them large. The largest (and ugliest) is the touristic cruise ship Viking Mars with place for 930 passengers. Then there are two Hurtigruten ships. From the left comes Kong Harald on its way to Skjervøy, from the other side Richard With with destination Tromsø. Both have a capacity of 590 passengers.

As usual the ships greet each other with the ship’s horn. Again and again they toot, apparently checking who will have the last word. Finally some minutes after she ships have passed, Richard With toots a last time for half a second and Kong Harald answers the same way. Then it gets silent.

I enter the tiny hut and take some pictures before I make myself at home. It’s cosy!

I soon realise, that I may have the hut for myself this night but definitely not the place. The french couple has gone but in the next hours many other people will appear “on stage”.

Dramatis personae: A couple from Amsterdam. Two people from Lithuania (he’s here for the 7th time) with friends. A group of Finnish scouts. Some more random people. M. and F. from Bavaria.

With the latter two I spend the evening and night. They are the perfect outdoor hosts. They already have collected wood for a campfire, that is soon is burning. We sit round the fire and chat about all sorts of things. I’m even invited to a glass of red wine if I have a glass. No, I don’t have any glass or cup but I have a pot of yoghurt. I only have to eat the yoghurt and clean the pot and – voilà – I have a high standard quality wine glass. Later this evening F. surprises me once more: He brought a travel guitar and so we have live music while we watch the sun slowly lowering but mostly wandering to the right.

At 0:28 the sun has vanished behind the island Nord-Fugløya in the north.

Will it be visible in the mountain gap at 0:44, the time when I think it’s lowest? Yes, at 0:42 it shows up and at 0:44 it is mostly visible again. It’s not my very first midnight sun I see, but a very beautiful one. I’m glad, that I have come here.

I take some more pictures – from the lighthouse and hut and from the mountains behind whose red rocks now seem to gleam by themselves.

Then I say goodbye to my “outdoor hosts” and enter the hut to sleep.

I decide not to take the tiny room under the roof but to roll out my camping mat in the main room. The camping mat and I have some disagreements on the topic of sleep comfort but anyhow I sleep quite ok. Just much too short. Because the next day is today and today is Monday and Monday is a working day. A quite tired working day but it was worth it. I never regret being in nature.

In Tromsø the first sunset will be in three days, at the Lyngstuva Lighthouse it will take another day, because it’s a bit more north. Now I’m looking forward to spot the first star. The last one I think I saw in the end of April.

Travelling from ice to summer Jun 22 2023

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

This photo was taken three days ago:

These photos were taken three hours ago:

Quite a contrast, isn’t it?

18 June (four days ago)

I stand on the sea ice for the last time as part of the polar research expedition with the ice breaker Kronprins Haakon. It has become quite foggy and we will close the ice station earlier due to bad visibility. If you cannot spot the polar bears it is not safe and we had quite a few of them the last two weeks.

19 June (three days ago)

Today we stop the ship several times for the usual CTD casts to get the salinity and temperature of the sea water in different depths. For science it is always interesting to get comparable measurements. One way is to do a transect, a series of the same type of measurements in different locations, mostly in a line. Today we do CTD casts at 2° W, 1° W, 0°, 1° E, and 2 °E. So today we have crossed the Prime Meridian.

For doing CTD casts the ship must stand still. At 1° E I use this to fly my private drone from the helicopter deck for the first picture above. (Memo to myself: do not fly a drone in fog, it is hard to land.)

20 June (two days ago)

After four days of fog it finally clears up in the evening. And for the first time in 18 days we can see land again, the long and narrow island Prins Karls Forland.

We can get a lot of information about what’s going on on the TV. On channel 9 there is OLEX, a navigation system. I see, that Helmer Hanssen, another research vessel owned by the University of Tromsø is nearby. The ships are getting closer and closer and I go up to the helicopter deck to take some photos. There’s a reason for the ships to meet. Malin, a researcher in the field of arctic and marine biology is transferred from our ship to Helmer Hanssen by boat. She will join another cruise.

21 June (yesterday)

In the morning we have approached Adventfjorden, where the main city Longyearbyen is located. Due to the touristic cruise ships occupying all dock places we will stop in the open water. From there we are transferred to land by boat as well. I’m in the first boat because I want to meet people in Longyearbyen at Forskningsparken. There UNIS, the university of Svalbard is located and a department of the Norwegian Polar Institute, too.

We get a car transport there and I meet Vegard, that helped me with drone flying and Luke, that I have worked with quite a bit. Luke and I have even time to get some outdoor lunch in the summery town. It’s sunny and more than 10 °C. (Too warm for me.) He mentions that it got quite green in Longyearbyen. And I spot the first flowers.

At the airport there are long queues everywhere. It is not build for large groups of slightly disorientated tourists. But we arrived early. Shortly after half past two we lift off. I glue myself to the window to see the fjords, the mountain chains and the glaciers of Svalbard passing by.

Spitsbergen in June — from the plane III

Amidst between Svalbard and Tromsø I manage to spot the arctic island Bjørnøya in the haze. For the first time in my life! The photo is heavily processed to make Bjørnøya visible.

And then we land in Tromsø where the vegetation just has exploded in my three weeks of absence. Everything is green and there are flowers everywhere. I am lucky and get a lift home. (Thank you, Tore!)

22 June (today)

I drop by in the office to meet my colleagues. Good to see them in real life. We talk about the cruise and many other things. But after work I take a bath in the sea. So refreshing when it is summer and 25 °C! That’s more than twenty degrees warmer than four days ago when I navigated my small drone to take a photo of Kronprins Haakon in the sea ice somewhere between Greenland and Svalbard.

23 June (tomorrow)

Tromsø is my work home, but Obbola in Sweden is my home home. Tomorrow I will travel there. If everything goes well it “only” takes 18 hours. And then I finally will be united with my wife Annika again in our cosy house by the Baltic Sea.

Snowy intermezzo May 27 2023

Last week it felt like spring is finally coming. Flowers were blooming in the forest, the snow had melted away rapidly and even the birch trees finally had become green.

Since then it had been raining a lot. Yesterday it got quite cold and the rain turned into wet snow.

There were snow showers the whole night and this morning, too with temperatures round 0–1 °C. Is this what spring looks like? And we’re talking about the end of May.

Alas it was only a short intermezzo and while the mountains still look whiter than before snow has melted away throughout the day.

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.

My first Thursday paddling 2023 May 4 2023

Today I was joining the “Thursday paddling” of the Tromsø Sea Kayakers Club. They started the season two weeks ago, I joined today for the first time this year.

At 18:00 a group of 13 kayakers left the shore by the boat houses and headed to Telegrafbukta, the small bay near my apartment. In the dull weather the kayaks and the paddlers in their drysuits always look quite colourful.

Although I’ve already been paddling in Sweden several times this winter it took me some time to find a rhythm. When I’m alone, I use to paddle slower.

At Telegrafbukta we decided to continue to Sydspissen, the southern tip of the island Tromsøya. There we turned back, paddling through snow showers.

We already saw it on the way there – there was very low water at Telegrafbukta, or just “Bukta” as the locals say. We took a break there but only a short one. The weather was too chilly to be comfortable.

We talked about the weather and came to the conclusion, that summer probably already was on first of May and now summer season is over. I’m not completely sure, if this theory will prove true, but on the way back spring or summer seemed to be far away.

It reminded me at last years first Thursday paddling. It was on 28 April and the weather was as snowy as today. Let’s see how the weather is next week.

A sunny car trip to Jøvik May 3 2023

As in many other countries 1. May is a rød dag, a red day which is an official holiday. The weather is beautiful and I decide to do something I haven’t done for a long time: a car trip.

I take the car to Jøvik, a village in Tromsø municipality located on the peninsula Lyngenhalvøya, home of the impressive mountain range “Lyngen Alps”. As soon as I leave the E8 travelling is slow. On the one hand there’s a lot to see, on the other side the roads are in a pretty bad shape.

Just some photos I took on this wonderful day trip:

Tar du vårbilder? May 2 2023

What is the difference between these two photos?

Half an hour and round about 60 metres in altitude. The first photo shows – quite visible – a bunch of tussilago flowers, the second one – pretty hidden – a tombstone on the Elverhøy graveyard.

I cannot answer why the differences are so immense on the island Tromsøya. I only can observe that while it looks like spring is coming to the coastal parts the ridge of the island is still wintry. There are old ski tracks and the lake Prestvannet (96 m) is still covered with ice and snow.

I walk round the lake. Some parts of the way are free of snow, most aren’t.

I take a photo from a bench. A woman passes by and asks me: “Tar du vårbilder?” – do you take spring pictures? Well, kind of … .

I have an appointment at 18:00 so I leave the “mountains” of Tromsø and descend into town. While the small slide near Prestvannet is still snowed in the playground lower in town is completely free of snow. And I don’t think, they have underfloor heating. (Not impossible in Tromsø.)

Later, at 22:45 I walk to the bus that brings be home. It’s still quite light outside. No wonder, it’s only 20 days left to the period of the midnight sun.

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!
