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!”

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.

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!

Tussilago in Tromsø 2023 Apr 24 2023

Yesterday I wrote I would write about Tussilago in Tromsø as soon as i see it. This morning I saw the typical yellow blossoms on my way to work. First a dozen, then a hundred, then a thousand. As early bloomers they apparently don’t have a problem with snow.

Addendum

Even some steps away from my doorstep almost hidden by the snow I found Tussilago.
