Ice station one and polar bears Aug 25 2024

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

For days we wondered, will we ever have an ice station on this Fram Strait cruise in open water? But then at 14° 21′ W, 79° 02′ N we found a large ice floe to work on. Shortly after nine o’clock I finally was on the ice again!

But I wasn’t here to take snapshots but to fly drone and to take a lot of photos from above.

I had issues with the drone from the Polar Institute, so I fetched my private one. First I had to calibrate some sensors, especially the compass and then I put the drone into the air and made some photos to check the image exposure. Ok, looks pretty good.

Test photo II – Kronprins Haakon in the ice

Now I flew the drone in a rectangular zig-zag pattern. That’s a bit tricky, because the drone is positioned by GPS while the ice flow is drifting. Since I wasn’t sure if I covered every part of the ice station I flew a second round. The single photos look like these:

Before going on board I took a couple of photos on the ice.

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

On board I uploaded the photos first into my laptop and then into the program OpenDroneMap that would stitch the photos together and add geographical information. And then it was 11:30, lunch time!

After lunch I went up on the bridge on deck 8. Together with two others I was observing my segment checking for polar bears, cracks in the ice and weather. There were several polar bears around but all were further away. I also had a VHF to keep track on the people on the ice. I had two shifts, 12:30–13:15 and 14:00–14:45.

After my second shift I got to know that we had a polar bear in front of the ship. So one of the bears that we had observed for hours had finally decided to pay us a visit. That meant of course that all people had to leave the ice. On the helicopter deck many people were around to watch the bear.

And there it was – a surprisingly white curious fellow that examined our ship. Did it smell the cake?

In the meanwhile OpenDroneMap finally created a properly rendered orthophoto. I was relieved because I was not sure if my drone photos were sufficient. This is an excerpt:

In the afternoon I had fixed the issue with the other drone. At 19:00 I would have another opportunity to go onto the ice to re-calibrate and test it. Our ice visit was however postponed because another polar bear was paying a visit. It looked much thinner than the other one, but on the other side the fur was wet. So photo shooting again. It surrounded the ship and then stopped, laid down onto its stomach, pushed itself forward with its furry feet and then rolled in the snow before it continued its walk.

We had to wait some time but then the ice was clear and I had time to test the drone on the ice. It worked. Hopefully I would be able to use it on the second ice station on the next day but the forecast does not look promising. Too much wind.

I shot a drone selfie and then I was ready to go on board. I just had to put my hand into one of the polar bear paw prints for size comparison.

The bear won!

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!

A short ski tour to the cabin Trollvassbu Feb 11 2023

Prelude

What do you need to go skiing? (A) snow? Or (B) a shopping cart?

This week started warm, rainy and very windy. On the Norwegian sea a full storm was raging. Boat traffic was cancelled, bridges and schools closed. Here’s a Norwegian article: Uværet stopper fergetrafikk og skoler stengt – NRK Nordland.

Tromsø however is quite protected by the surrounding mountains. I saw this shopping card was thrown on the empty parking lot, nothing more. The ice was probably more dangerous but I have good spikes for my boots.

Two days ago the temperatures had dropped and snow was falling gently when I went to work. Yesterday it was still snowing, but less gently as you can see on the second image.

Skiing

Since then round 30 cm of snow had fallen. I packed ski and other stuff into my car and drove to a parking place on the mainland. It took a while to go there. First it’s 40 km and then there were some heavy snow showers. Sometimes it was hard to follow the road and I almost went through a red traffic light because it was snowed in.

Then I reached the parking place. Is it cleared? Well, I don’t know, I only see white. Let’s try …

I tried to back but it was obvious, that the car got stuck in a snow drift. The problem was not only the packed snow under the car, but also a layer of ice under the snow. The tyres just were spinning. So I had to dig out my car and decided to do it before skiing. 15 minutes warm-up with my snow spade, then the car was free.

There was another car, otherwise I was alone. I dressed for the tour and started. Plan for today: the cabin Trollvassbo, just 4 km away. It started snowing and wind increased. Mountains and other features were invisible. The snow was loose and my skis sank 15 cm with each step. But I was lucky. The pale spot in the distance turned out to be three women, that had stayed overnight in Trollvassbu. Following their ski track was of course not much less exhausting and I hadn’t to care much about navigation. Nice!

After two kilometres the track was lost in nothing. Snow and wind had filled the track. Sometimes it cleared up a bit and I could see the mountains, sometimes a new snow shower approached.

But then, after 3½ km I spotted it – the cabin. Somewhere behind the drifting snow.

Another 800 metres and I arrived. The cabins of the Norwegian tourist association DNT are locked, but luckily all with the same key – which I had with me today. So I could take a rest inside.

Oh, lovely! The cabin was cosy and still warm. I took a frugal lunch – water and crisp bread. I regretted, that I didn’t took some real lunch with me, here where I could use the gas stove. Anyhow I stayed there for almost an hour.

I took a photo of the snow drift behind the cabin and then started my way back to the car. Just while I took out the camera to take a picture of a mountain a snow cloud approached. Half a minute later the mountains was gone. Another half a minute later I skied through a heavy snow shower.

I put off my backpack to firmly tie up my snow spade and continued. Anyhow this was last stormy shower. Then it cleared up a bit and I could see the mountains again. I was more easterly than on the way there. Here the terrain was more sheltered from the wind. This means less wind but also deeper snow. Since there was no track left I skied through 20 cm of loose snow. So although I skied down a bit I was hardly any faster than on the way there. But that doesn’t matter, it’s not a competition.

The whole ski tour took less than 3½ hours including the break. Plus 15 minutes of shovelling. Plus 1½ hours of car driving. It’s near to impossible to reach all these great places round Tromsø by public transport, especially on weekends.

Warmly recommended if you have a car and want to have an easy tour without steep slopes. Perhaps you’ll get more friendly weather.

Jämtland tour 22 – the glacier of Helagsfjället Sep 10 2022

This article is part of the series “2022-08: Jämtland and Trøndelag”.

It is 23 August, day 9 of our hiking tour through the mountains of Jämtland. Today we take another day off and I decide to try to reach the glacier of the mountain Helagsfjället. I don’t know how near I can get but I’ll see.

This glacier is the Sweden’s southernmost and parts of it are visible from the Helags fjällstation. You can even see the mark of the top (1797 m) which is round 750 metres higher than the cabins.

On my way up I meet three men heading for the top. I hear that it is easy to climb, even for children. Other hikers will confirm that later. Well, perhaps I’ll do that another time but today I want to touch the glacier.

I walk first up on across county, reach the main trail and follow it for a while. Then I turn right to follow a smaller path heading to the glacier. I reach a field with large rocks and boulders. Carefully I follow the cairns that mark a path until I stand in front of the first glacier tongue.

Time for a selfie!

I spot another glacier tongue. For coming there I have to climb over a rock outcrop. Mountaineers will laugh that I call it climbing but I’m more a hiker than a climber and as soon as I have to use both hands I call it climbing. The effort was rewarded. What an impressive view on the glacier!

I stand still for a while. First of all it is beautiful weather and then it is fascinating just to see the colours of the glacier changing while shady clouds pass by. And then I move again to take more pictures. And I drink some water and eat a bit of chocolate.

How long I stand there? I cannot say. I start my way back. My first view is on the radio station on the mountain Jalkedsåajja. This is where my sister and brother-in-law are today. But it is too far to spot if they are there right now.

While walking back I come to the small glacial lake that I already passed on my way up. Some people had written their names using stones. Wait – some people!? Only now I do realise that the whole area is covered with messages arranged by stones. An ancient social media stream – though without cat videos.

The whole tour took only three hours, with a lot of photographing and taking rests. If you plan to visit Helags you definitely should consider to give the glacier a visit. I keep my fingers crossed that you get nice weather, too.

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.

April weather – kayaking through the snow Apr 12 2021

Yesterday the whole day was sunny. The sun was warm enough that we could take breakfast on the terrace. At lunch time we took a bath at Vitskärtsudden. Of course the water temperature is hardly above zero, but it felt springlike to go barefoot over the sand of the beach. Yes – sand, no more ice or snow!

Today however:

In the morning it has started snowing and since then it has been constantly snowing at temperatures round 0.3 °C. A good opportunity for …

… kayaking! Although wind had become stronger the Baltic Sea still was calm. Maybe it was the snow, that created a wet blanket of slush and made parts of the surface slow and doughy, but that I don’t know.

I just took a tour round Lillskär, but took some photos with my Nikon. That took time, because each time I took photos the wind blew me back 50 to 100 metres again. But as I said, the water was calm and it didn’t took long to round the island, cross a field of floating slush, disturb some geese and return home.

Short experiences can be great and memorable experiences!

A photo from the afternoon – still snowing. The original photo looked almost black-and-white and so I made this composition completely black-and-white with a slide blueish tone.

The background: a line of trees, dimmed by the intense snow fall. The middle layer: A line of rocks in the sea, covered with snow. The foreground: The sea, covered with a layer of slush.

Kayak – crisp morning – roe deer – crushed ice Mar 20 2021

The week in five chapters – including photographers comments

Tuesday, 16. March, 7:45 – a short kayak tour

The blue sky invited to interrupt work and take a short kayak tour. It hardly needs preparation: Putting on the waterproof coverall, put the iPhone in a waterproof bag and drag the kayak over the ice to the islet Lillskär. Then it gets a bit harder to find a good place to set the kayak into the water. I found a place and some minutes later I paddled to the island Bredskär. The tour however turned out to be shorter than planned because between the islands Bredskär and Bredskärsten the Baltic Sea had frozen over in the night. I wasn’t eager to hack myself through the ice, so I turned and realised, that – as so often – the wind came from land and was fresher than expected. At time I do not have a real drysuit for paddling and moving in the thick neoprene survival suit is exhausting. But it’s great to be outdoors, even when the tour is only a tiny one.

Ice floes had frozen together over night

On the outside of the islet Lillskär the sea is open

Photographers comment:

It’s always like spinning a wheel of fortune, when you try to photo with an iPhone in a waterproof bag and your fingers are in rubber gloves. Sometimes nothing happens, sometimes you have waterdrops on the bag, sometimes the camera triggers too late and sometimes you’re taking pictures of your own gloves as in image #3.

Photoing like this is about visual storytelling, not about high quality photos you want to put on the wall of your living room. But on the other side, why actually not?

Yesterday, 6:30 –a crisp morning

-10 °C, could be the last cold morning before the warm air will arrive. I walked to the coast quite early and took some photos. One from the packed ice, that has frozen together, one of a funny ice sculpture that I discovered a bit further out.

Photographers comment:

Alas – a DSLR camera. Not waterproof and much heavier but much more fun to handle. The quality of the photos is of course superior but something is missing a bit: The beautiful warm light of the sunrise. The sun rises however already at 5:43, so I was almost an hour too late.

You have to decide: Do you want to sleep or to take better photos? It’s up to you.

Today, 8:30 – cautious visitors

When I went to the living room this morning I saw a movement outside. Right under the kitchen window two roe deer were eating leftovers of the bird food that was lying in the snow. Annika and I hold distance to the window and even though they were extremely cautious they didn’t seem to be able to see us through the glass. They continued eating for a short while and then went on. I slowly opened the kitchen window to give them carrots, but as expected they didn’t dare to come back. Now the carrots stuck in the snow and we’re curious if they’ll find them there the next days.

Photographers comment:

Luckily the roe deer stood on a metre of solid snow, so they could peek in and we could peek out and see them. The first photo gives a good impression of how near they were, even though it is taken with a focal length of 200mm.

Today, 12:00 – no winter bath

The whole day it has been above zero and at 11 o’clock it started to rain. In the need of fresh air Annika and I walked to Vitskärsudden. We weren’t prepared for a winter bath and it would have been quite useless since the whole bay was filled with ice floes and crushed ice and slush that lazily followed the slow waves of the sea.

Photographers comment:

Well, while the motive is quite ok, the grey overcast weather made the light so dull and poor in contrast, that the photo looks pale and boring. Should you photograph under such conditions? Well, of course! But don’t expect the best results.

Today, 15:45 – crushed ice

Where I started my Tuesday morning paddle tour now a large area of the sea was covered with the very same mixture of ice floes, smaller pieces of ice and slush. I went to Lillskär again – equally prepared as for paddling – and watched the ice floes. It’s mostly the trees of the neighbouring islands that prevent the scenery looking completely arctic, but it’s still impressive.

Finally I took my ice bath but since I didn’t get wet in my coverall it probably doesn’t count.

Photographers comment:

The conditions: bad. Again iPhone in a bag and rubber gloves plus the grey sky. Taking the selfie however was fun.

That makes me realise that I’m quite result-orientated when I make photos. Sometimes I just forget, that the process of photographing itself can be fun, last not least because it gives you reasons to do silly thinks like standing outside the whole night, wade through a mud bog or like today – just jump into the ice pool.

What was your last “crazy” photo action?

The last cold morning? Mar 10 2021

A clear blue sky, -20 °C – this may be the last cold morning here in Obbola. I was up early and went to the coast to catch the sunrise. The sea, where I paddled yesterday afternoon was completely frozen over again. Patches of ice fog drifted by – a clear sign that other parts of the sea are open (and that it’s cold). The fog partly hid the island Bredskärssten.

Ice fog in the morning hides the island Bredskärssten

When did you watch your last sunrise? Do it again! It’s always fascinating to see the sky and the clouds change colours– from soft pink to deep purple, from crimson red to bright orange. The sunrise position has moved more and more westwards. Now it’s behind the larger island Bredskär. The sun illuminated the drifting fog in spots of orange.

Now in mid-March the sun rises much faster than in midwinter and soon the colours went pale. Time to go back and to warm up. The parka and mittens kept me warm, but the ski pants were a bit too thin when sitting on the ice.

Outdoor exhibition Feb 7 2021

A Covid-19 compatible art exhibition visit.

What’s that? That’s the Baltic Sea off Obbola. When you stand on the ice, you see the frozen surface reaching to the horizon.

Today I take the skis to explore our coast the first time from the frozen sea. I head south and ski along the coast until I reach our beach Vitskärsudden.

From there I can see an apparently higher wall of ice at the southern tip of the island Tarv, 1.3 km away in the southwest. I do not know this part of the Baltic Sea in wintertime. Is it safe? Can I dare to cross the ice? Well, let’s check for tracks or prints.

OK. There is roe deer prints, footprints, ski tracks, ice skating cuts and a snowmobile trail. And I can see skiers on the ice. Doesn’t look too dangerous. Of course I have my ice picks round my neck as a rescue tool in case of breaking into the ice. Spoiler: the ice sings but nothing happens.

I ski across the ski and there it is. This year’s ice art exhibition:

How large are the exhibits? Here, where I took the photos mostly between 150 and 200 cm.

A selfie in front of Tarv’s southern tip

Most impressive is the ice wall along the coast. But some of the ice formations on the solitaire rocks look interesting, too. If you lay down they look like mountains.

I follow the coastal line of Tarv and finally find a place where the ice wall is so low, that I can enter the island. On the sea there was hardly half a cm of snow, here it’s more half a metre. And a lot of forest.

Parts of the forest are quite dense but after a while of squeezing between the trees I find a snowmobile trail that leads back to the coast. Although it is one and a half hours before sunset the light starts to become a bit orange.

Now I ski back quite the same way.

When our House comes into view I see that the front chimney is smoking. Has Annika warmed up the uninsulated winter garden? Yes, she has! A fire is burning in the stove and I even get a hot chocolate. A warm welcome! And a cool tour!

From dawn till dusk Jan 29 2021

After some cloudy days the sky cleared yesterday afternoon so that Annika and I could do cross-country skiing under the full moon. Beautiful!

This morning was crisp (-17 °C) and sunny. I took a short break from work and skied a bit along the icy coast, just in time to see the sun rise behind the layer of clouds at the horizon.

I stopped working already at 14:30 and directly put on the skis again. I managed to follow more or less the icy edge to the bay Vitskärsudden, our favourite bathing place. The sun was going down already and lit the ice in warm sunset colours. The scenery looked really arctic. And it felt arctic, too. I felt quite cold and was glad, that I had a down jacket with me to put over the touring jacket.

Ice covered rock in the frozen Baltic Sea

It was mostly the forests that revealed the fact, that it’s not the Arctic Ocean but the Baltic Sea that I ski along. And of course the houses, hardly 200 meter away from the icy shore.

When I arrived at Vitskärsudden I realised that – unless another storm would break all the ice – bathing season is finally over. I posted a picture on Facebook in the Umeå winter bathing group and then returned home, still on skis but mostly following the roads.

Even with taking the photos the tour took less than two hours. But it felt like having holiday. It’s really a privilege to be able to live here!
