Clearing snow in Tromsø Jan 11 2025

This evening I was out in the snow. I walked 1.6 km and this was the route:

What happened? Was I disorientated? Drunk? Drugged? No, none of that. The snowfall was the reason. It has been snowed more or less the whole day and in the last 24 hours (22:00 – 22:00) we got 26 cm of new snow resulting in a snow depth of 103 cm.

I am lucky. The front yard beside the parking place lies about a metre deeper and I don’t have to pile up snow but push it more or less straight into the front yard. The garden gets fuller under the winter and so the way gets longer. Today’s snow clearing covered a distance of 1.6 km according to my tracking app. The last metre is the hardest, because there the snow is still soft and if you made a careless step there you might land in hip deep snow. Or in my case after moving my legs up and down a few times even deeper:

Since it hasn’t stopped snowing yet I will have to shovel again tomorrow. To be honest, I like it. I am outside and get some exercise, I can do it in the dark and the front door of my apartment is never more than 20 metres away. But I want to use my skies tomorrow as well. Last chance before the heavy rain arrives.

Advent season home in Obbola Dec 16 2024

It was four days ago that I arrived in my “home home”, Annika’s and my house in Obbola. And we got some winter weather. First we got twenty centimetres of snow. We took a Saturday promenade to our favourite beach Vitskärsudden which looked like this:

It continued snowing and blowing the whole Saturday but then it cleared up in the night and Sunday morning the sky was clear at temperatures round -12 °C. I waited until 9:20 to watch the sun rise over the sea.

Later that day Annika and I took the very same promenade to Vitskärsudden again but it looked so differently in the sun.

In the night it became stormy. We have experienced some storms here before, but this was the very first time that I couldn’t open the front door at all. It was completely blocked by snow. I had to climb out of the snow-plastered kitchen window and shovel away the compact snow drift that blocked the door.

And this is how our house looked like some hours ago. Now it is clear and calm weather and -14 °C.

November thaw Nov 10 2024

It took only four days to melt away 47 cm of snow.

Last Sunday I used skis to glide over the snow in the forest. However, the forecast at yr showed already that this pleasure would be temporary. And yr was right. It became much warmer and rained a lot. My way home on Wednesday was wet and so was the jogging on Thursday.

On Monday the snow depth had been 47 cm. On Friday it was zero. Thaw and the amount of rain led to flooding and several roads and bridges were closed. In the forest and on the bogs it looked like autumn was back.

Today I took another promenade through the near forest and felt like being back in October regarding the weather. With a clear difference: Having this cloudy weather it is not longer bright outside anymore.

Sixteen more days and the polar night in Tromsø starts with the absence of the sun for the following seven weeks. The darker it gets the more I’m longing for snow. It makes everything brighter.

Ski premiere 2024/25 Nov 3 2024

After the snowfall in the first half of the week …

… snowfall continued in the weekend.

Saturday, 2 November – walking

When I woke up yesterday morning another 10–15 cm of snow have fallen over night and it is still snowing. I get myself dressed, grab my camera backpack and go out. At the kindergarten I follow the way to the ski jumps. The light is still dim and I am quite alone. A strong wind gust blows snow from all trees and for some seconds snow is everywhere in the air.

I turn left and head to the small pond. The pair of Red-throated loons has left long ago and now the pond is frozen and covered in snow.

From there I cross the small grassy bog and follow some of the many forest paths.

I walked here quite a lot last summer but now that everything is covered in 25–30 cm of snow I miss some of the paths. That circumstance gave me wet feet quite soon. While trudging through the snow I suddenly felt my rubber boots sinking in something else. Seconds later I stood knee deep in a patch of mud. Brownish water eagerly filled my boots and the mud was so sticky, that it took me a minute to get free again. The rest of my walk I had wet and pretty cold feet. Back home I praised the inventor of the hot shower. (And that of the shoe dryer.)

Saturday, 2 November – jogging

Two hours later I go out again, this time to jog. I just have started again three weeks ago and I want to continue in wintertime as long it is possible. This time I stick to the “official” ways – some of them are already packed and groomed for cross-country skiers. Luckily you are allowed to bike or walk on the side of these tracks. It is fun to jog while it is snowing again. And my feet remained almost dry (just a bit of snow came into the Icebug winter running shoes).

Sunday, 3 November – skiing

This morning even more snow has fallen and I decide to take a ski tour. Not elsewhere but directly from home. I fetch my “fjellski” and poles from the shack and start my ski tour right from the entrance of my apartment. As the day before I pass the kindergarten and the small pond. The snow depth has grown to 45–50 cm and the skis sink in 20 cm with each step. Mostly I take those forest paths that are not too steep, but sometimes I follow the ski tracks where even I am as twice as fast.

Some more snow showers pass while I’m skiing cross-country. But then the sun comes out and colourises both sea and clouds deep orange. While I try to find a good spot to take a photo (I have my DSLR with me) the sun has begun to hide again. Photographer’s bad luck!

I pass the lake Rundvannet, while another snow shower approaches. No bathers today.

While I am heading back the sun comes out again, this time for longer. It is pretty low and soon disappears behind the mountains. In 3½ weeks polar night will start in Tromsø.

The huge ski jump of the Grønnåsen Ski Jump Center is a good landmark. Since it is on top of a hill it is visible from many places. Today I will climb up and finally ski down the ski jump to see how far I … well, just kidding.

From the ski jump it is only 800 metres back home. I ski the whole distance although I always feel uncomfortable skiing on the roads. The snow is so slippery there. After 7.5 kilometres – sometimes on tracks but mostly cross-country I am back home again.

Some hours later – 16:12. It is dark and another snow shower has approached. More snow! Anyhow it is only a temporary pleasure. Next week it will get much warmer and from Tuesday 78 mm of rain are expected for the next seen days. I guess the road conditions can be pretty ugly then. I am glad that I was outside in the “preview” of winter 2024/25. Let’s see when the next snow will arrive.

October snow in Tromsø Oct 31 2024

After a period of warmer weather it got colder the weekend and on Monday, 28 October it started to snow. After work I took the bus to the lake Prestvannet and walked home. Some snow showers passed through making the landscape brighter. Most small paths are still wet and some are pretty muddy but apart from that it looked so nice with the first cm of snow.

The next day more snow came at temperatures round zero. After work I walked back pretty the same route (there are zillions of small paths leading through the hilly forests and over some overgrown bogs.) New snow depth: 6–7 cm. That makes a difference, at least visually.

Yesterday I took the bus home, today I walked again. It is 31 October, the last day of the month. The temperature is slightly below freezing and the now snow is fluffy. New snow depth: 15 cm. As the days before I pass the lake Prestvannet that starts freezing over at the edges. It is fun to plunge through the snow but as long as I leave the main tracks – and I do – I’m still glad about my rubber boots because under the clean white blanket of snow there are the same mud puddles as three days before. On the broader gravel paths however the first people have started using their skis.

Fun fact: the photos #2, #7, and #15 show the same motive. From open swampy water to frozen and snowed over in three days.

Autumn forest, snowy mountains Sep 21 2024

When the temperature have dropped to 2–5 °C and the wind blows and it rains, rains, rains in Tromsø, then the season is a matter of altitude. In the lowlands it is autumn yet the mountains are covered with fresh, white snow.

Back in Tromsø – an autumnal walk Sep 19 2024

After five weeks of travelling with just two intermediate days I have come back to my work home Tromsø two days ago. Now I’ll stay here for a while.

Yesterday I have started working in the office again and today I walked home from the lake Prestvannet to my apartment after work. That’s five kilometres. Weather and nature have been showing, that summer says farewell and the wind is strong enough to tear out some of the tree’s green leaves, too. From today on I’ll try to take a one-hour walk every day. Let’s see, how long I’ll keep up that habit.

Some photos from today. Just the iPhone and some editing in Lightroom.

Ice station two and icebergs Aug 26 2024

This article is part of the series “2024-08: Fram Strait cruise KPH”.

When I woke up in the morning of the 20th of August my first thought was: will there be another ice station? I peeked through the port hole and – yes – we were at least in the ice. From the helicopter deck it looked like this:

Round nine o’clock the ice station is started. Eleven people are involved – four scientists and students actually doing science, a polar bear guard on the ice and two times three bridge watches taking turns to observe everything from above. I take the morning shifts, the weather is not good for drone flying anyhow. Yesterday we had a lot of polar bears on the ice, today it is quiet. It is more the fog that could lead to problems, but even the visibility is ok. Good luck.

In the afternoon it has become too windy to fly the drone. I get onto the ice anyhow to take photos for outreach. Time to show people doing research on the ice. It is a lot of manual work. Carrying things down the gangway, pulling sledges, using drills with coring equipment, a saw to slice the ice cores, a digital thermometer and for a lot of data – paper and pencil. This may sound antiquated but writing down notes works often works better in harsh environments than using electronics.

Ice work I: pulling equipment (Lia Herrmannsdorfer, NTNU in the front)

Ice work II: taking cores (Henrik Fisser, UiT and Dmitry Divine, NPI)

Ice work III – measuring (Henrik Fisser, UiT and Dmitry Divine, NPI)

Ice work IV – writing down data (Henrik Fisser, UiT)

Ice work V: measuring an ice core (Alexandra Pliss, NTNU)

Later, just before dinner people who never have stood on the sea ice before become an opportunity to do that. I was on the sea ice three times since yesterday, so I volunteer for bridge watch again. The weather has become more and more nasty. It is raining and wind is blowing with temperatures round +1 °C. So it looks from the bridge:

At 17:30 (dinner time) the second ice station is finished. Now we will head back more or less the same way we came from. I take some photos from the helicopter deck, especially from the turquoise coloured melt ponds that I have never seen before like that.

Melt ponds on the sea ice in the Fram Strait I

Melt ponds on the sea ice in the Fram Strait II

Melt ponds on the sea ice in the Fram Strait III

At 9 o’clock we reach the ice edge and sail through the open sea again. Time to say farewell. I do not know when I’ll may see my beloved sea ice again.

Anyhow one thing was different than on our way there some days ago: icebergs are drifting on the sea. We see a lot of them on this and the following day. Some of them are small or medium sized …

… one of them was huge. I am able to take a drone photo from above. I estimate that the cliff to the right has a height of 10-15 metres.

There was one difference between the two ice stations. It is visible on the map:

While the 2nd ice station started and ended at the same place, the 1st ice station didn’t. This is because the 1st station was on drift ice while the 2nd station was on fast ice. Fast ice is either grounded or it is connected to land, in this case Greenland.

Although Greenland with islands was more than 50 km away it was visible on the 19th of August. I was really surprised and also happy – I have never seen Greenland before. And I managed to take some blurred photos (cropped image, 600 mm focal length).

Feels like I should visit that place sometimes …

Mooring recovery and deployment Aug 24 2024

This article is part of the series “2024-08: Fram Strait cruise KPH”.

For science it is important to get measurements, preferably a lot of measurements. That’s not so easy if you have to take the icebreaker, you have only one and very limited ship time. One thing to go round this is to have sets of instruments that are moored at different locations in the sea. A weight and a buoy keep the communication cable with the instruments vertically and make the mooring stationary

On this cruise we had to recover seven moorings between 78° und 79° N and between 2° and 10° W. To communicate with the mooring a so-called hydrophone is used which can transmit and receive acoustical signals. The hydrophone is used to find the mooring and also to release it. Then the mooring will detach from the weight at the bottom and the upper buoys will slowly drift to the surface.

Then you have to find the mooring . Visually. That’s not an easy task because you will release the mooring in a certain distance to the ship to avoid crashing it into the hull. Beside of that it was pretty foggy this day when a team of NPI engineers and the ship’s crew tried to recover the first mooring with the id F10-19.

But look: There it is! It was found a while ago and our ship Kronprins Haakon is already in position for the recovery.

Now it takes a while to get everything on board without to destroy the scientific instruments. A lot of winch work is involved in the process.

This recovery at 2° W took approximately took one and a half hours. I think that’s quite fast if you consider, that the depth of the sea is round 2650 m at this place. That’s a lot of cable to pull up.

In the afternoon the second mooring recovery took place, this time at 3° W. I’ll show some more photos because this was one of the rare occasions when we actually had sun.

When the mooring was on board the collected data had to be fetched from the instruments and checked while other research was going on in parallel. And so the work continued until the last mooring was recovered three days later.

Of course you want to proceed with the continuous measurements. So on our way back the same amount of moorings had been deployed at the same places. Sometimes a mooring could be re-used, sometimes instruments had to be calibrated on mainland and a replacement was deployed. Each deployment started with the heaviest part, the iron weight that moors the cable to the ground following by the cable, the instruments and some buoys. And then again – a lot of winch work, setting carbines and so on.

Today we got the message: “All moorings are deployed! 🎈” – Great news!

P.S.: One instrument was lost but already in November. The data anyhow is saved elsewhere in the mooring and could be recovered.

Wind and weather, water and ice Aug 21 2024

This article is part of the series “2024-08: Fram Strait cruise KPH”.

Wednesday, 21 August 10:36. It’s Annika’s and my fourth wedding anniversary, but I’m far away from her. I’m on the icebreaker Kronprins Haakon in the Fram Strait at 78° 50′ N, 12° 16′ W, that’s between Greenland and Svalbard. Air temperature is +0.2 °C, water temperature -0.1 °C. It is day 9 of the scientific cruise FS2024 of the Norwegian Polar Institute. Today I have found some time to write a blog article and also to publish it thanks to the fast satellite internet on board.

This article is about the journey, about the elements, not about research. I’ll come to this later in other articles.

13 August

Today the 2024 expedition to the Fram Strait begins. Short name: FS2024. 19 participants and 20 crew members are on board. Round 18:00 we leave the port, sail along the Adventfjorden and turn into the 107 km long Isfjorden. When we reach the open sea the sea gets rough and our ship starts to pitch and roll in the waves and not all people feel well. I have a cabin in the bow of deck 3 and the larger waves splash sea water against the port hole.

Sailing along Svalbard, soon we will leave it behind

14 August

In the night the wind has calmed down. We are heading west and it is quite foggy. This year there is much less sea ice in the Fram Strait then usual at this time. Less ice coverage means increased air humidity and that results in fog.

15 August

It continues to be foggy, no need to take any photos of the sea. But in the afternoon the sun manages to fight its way through the fog. This results in two hours with blue sky and also in a phenomenon I never experienced before. A fog bow. As with usual rainbows the sun is in the back so it is not a halo. The water droplets of the fog are so small, that the colours are very weak and so the fog bow looks almost white.

16 August

Research as usual: Two mooring recoveries and several CTD casts, MSS casts, optical casts. The weather: also as usual. It is foggy again and it will stay like this the whole day.

It is not clear whether we will have any ice station on this cruise. The ice stations planned for yesterday and today have already been canceled due to the lack of sea ice and tomorrow it doesn’t look better. At lunch time at least the first chunks of ice have appeared. That’s a nice change in the uniformness of the foggy weather.

17 August

For days we have been checking the wind speed on windy that forecasted winds up to 40 knots for today. That’s 20 m/s. And the gale has already reached us. The waves have started to get larger with spray on the top. They splash against the few ice floes drifting around us.

In the afternoon all research has been cancelled because of the increasing wind and growing waves. After dinner I go down to deck 3 and into my room. We have average wind speeds of 22-23 m/s now. The ship pitches a lot and in combination with the high waves (I think, 3–4 metres) the port hole of my cabin is occasionally under water. These are some screenshots of a short movie I made with my mobile:

Now the ice floes are not gently drifting anymore but are at the mercy of the waves. Is the storm our friend and blows that one nice looking ice floe in the north towards us? Or will the swell break the ice into smithereens?

18 August

Half past seven – breakfast time. Wind has calmed down to 15 m/s. We are at 78°50′ N und 9°30′ W. I work a lot this day on my computer, hardly looking out of the window. We want to reach 14° W tonight. That’s not so so far away as it sounds, since one degree west means a distance of just 21.5 km at these latitudes.

At 18:30 all people involved in sea ice work meet up. That’s also the people doing “bridge watch” looking for polar bears from the bridge at deck 8. We get a safety briefing for being on the ice and then we see a presentation created by ice expert Henrik that shows the ice situation. There are two possibilities for an ice station for the next day.

Planning for the ice station (slide by Henrik Fisser, UiT)

It’s hardly believable – we are still in open water with less than 1% ice. But we have a fresh satellite image and people who know ice so I’m optimistic. If only the ice is stable enough.

At least there are some flat ice bergs around.

19 August

At 4 o’clock in the night I wake up. I know this noise, the vibrations, these movements. Kronprins Haakon breaks though the ice! I look through the porthole – we are in the ice! Despite the early hour I get up to take photos on the helicopter deck. It looks so different from the previous days.

Shortly after nine o’clock I take my mobile phone to make this photo:

And this means – after a year and two month I finally stand on the arctic sea ice again. I missed it, I just love this environment! Today’s mission: Flying a drone to produce images for a so-called orthophoto. But that is another story to be told a bit later.
