I was shocked last summer. Then I realized it was becoming increasingly difficult to get interesting recordings of glaciers. I was missing out on unique opportunities if I would not change my traditional methods of recording glacier sounds.
Glaciers that have so far been accessible with all kind of sound seems much quieter than before. Finding good places seems to be more difficult each year and to reach them with all of my equipment are getting even more difficult. Many glacier toes in Iceland seem to be turning into „dead ice“ at the toe end so they will not be crawling under its own weight anymore just lay where they are until they melt down.
One of this glacier which has gotten thinner, smaller and quieter each year is Svínafellsjökull glacier.
I spent three nights recording there last summer without recording anything „interesting“
The temperature varies between 2°C over the night, to 18°C during the day. During the night it melted little but it started to melt intensely at dawn and became very intense during the day, especially when the sun was shining on the glacier.
The following recording was made in a small „Ice cave“ in the glacier toe, 27th of May 2019. The time was around 8 AM, about an hour after the heat started to rice and the melting began. In this 27 minutes long recording  you will clearly hear the melting of the ice increase until I became afraid about the microphone and I stop the recording.
You can hear several times a deep rumble sound, probably because the glacier is crawling high in the mountain. Many other strange sounds are in this recording, some are known, while other unexplainable. I was never close by so it is not sound from me.  Some of them are loud, so be careful, do not listen to the recording on high level.
Other sound in distance are tourists, almost constant motorist traffic. But fossil fuel machines and humans mobility are sadly one of the reason for rapidly shrinking glaciers now a days.
Quality open headphones are recommended while listening at low to mid level, or in speakers at low-mid level.

Natural silence is my favorite recording material, mainly because now a days it is so difficult to find it and it gets more difficult every year. I have been interested for salience in many years, or since I discovered it in my cycling trip all over Icelandic’s highlands about three decades ago. It was before the tourist boom and before Icelanders started to travel in their own country. So I was sometimes alone for many days in the desert. This moments in deep silence have inspired me so much it has shaped my life for lifetime.
One of this quiet places in Iceland was north of Vatnajökull glacier.
Shortly after the millennium, the traffic in this area increased a lot, especially because the Icelandic government had planed to build the biggest dam in Europe (Kárahnjúkastífla dam)  to make electricity for one ALCOA aluminum smelter in Reyðarfjörður, east of Iceland.
All that project ended as a huge natural disaster, which also split the people´s community in Iceland into two groups with and against this project. More information about this disaster can be found on Saving Iceland´s website.
Last time I visited this area was early summer 2018, I spent a night in Vesturöræfi on a place named Kofaalda.
I remembered my first thought when I sat up the recording gear. I was going to waste gigabytes for nothing because I heard nothing. Totally nothing. Well, there were some birds in distance …and yes, on the left side, behind hill about 2 km away there was the river Sauðá and on the right side a waterfall in Kringislá river about 4-5 km away.
I started recording.
It was not until last summer when I got opportunity to make a noise reduction on this recording, I noticed, after about 90dB gain this silence was rich of sound.
Most of this night I was struggling with rumble by gust. But between 5 and 6 o´clock the wind went down and something unexpected happened above end near the microphone.
Several bird species are in this recording: Dunlin, Golden plover, Pink-footed goose, Purple sandpiper, Common ringed plover, Snow bunting and Arctic skua.
Quality open headphones are recommended while listening at low to mid level, or in speakers at low level.

Storm petrel (Hydrobates pelagicus) is a seabird in the northern storm petrel family, Hydrobatidae. It is the only member of the genus Hydrobates. The small, square-tailed bird is entirely black except for a broad, white rump and a white band on the under wings, and it has a fluttering, bat-like flight. The large majority of the population breeds on islands off the coasts of Europe, with the greatest numbers in the Faroe Islands, United Kingdom, Ireland, and Iceland. The Mediterranean population is a separate subspecies, but is inseparable at sea from its Atlantic relatives; its strongholds are Filfla Island (Malta), Sicily, and the Balearic Islands.
The storm petrel nests in crevices and burrows, sometimes shared with other seabirds or rabbits, and lays a single white egg, usually on bare soil. The adults share the lengthy incubation and both feed the chick, which is not normally brooded after the first week. This bird is strongly migratory, spending the Northern Hemisphere winter mainly off the coasts of South Africa and Namibia, with some birds stopping in the seas adjoining West Africa, and a few remaining near their Mediterranean breeding islands. This petrel is strictly oceanic outside the breeding season. It feeds on small fish, squid, and zooplankton, while pattering on the sea’s surface, and can find oily edible items by smell. The food is converted in the bird’s stomach to an oily orange liquid, which is regurgitated when the chick is fed. Although usually silent at sea, the storm petrel has a chattering call given by both members of a pair in their courtship flight, and the male has a purring song given from the breeding chamber.
The Storm petrel cannot survive on islands where land mammals such as rats and cats have been introduced, and it suffers natural predation from gulls, skuas, owls, and falcons. Although the population may be declining slightly, this petrel is classified by the International Union for Conservation of Nature as being of least concern due to its high total numbers. Its presence in rough weather at sea has led to various mariners’ superstitions, and by analogy, to its use as a symbol by revolutionary and anarchist groups.
See more information at Wikipedia, eBird and Fuglavefurinn.
Largest colony of Storm Petrel in Iceland can be found in Elliðaey Island, near Vestmannaeyjar island, south of Iceland, but they can also be found in small numbers in two other places in south and east Iceland.
When I and Bob McGuire and Marino Sigursteinsson arrived in Elliðaey the 5th of June 2018, we were not sure if the Storm Petrel had arrived. It was almost too early for their breeding season.
So it was a big success when suddenly at midnight the air was filled with flying Storm petrels. I never saw this tiny bird, even though they were all around my head. They flew extremely fast like bats and disappeared in holes in the ground, and in the load wall of the old shelter.
I started recording inside the shelter because it was like hundreds of birds were heavily busy in conversation inside the wall, but outside and behind the shelter was a low lava cliff, named Skápar also with interesting soundscape. So I started to recording with other recorder there too.
Sadly I spent to much time talking in too short distance behind the rig, so most of the recording is spoiled with human talking. It is sad because this fabulous Storm petrel soundscape did not last more than two or three hours before they all flew to the sea again.
The following recording is what is left of the recording without the human chat. So the best part of Storm Petrel is sadly missing. Instead other bird, very similar is common in this recording. It is Leach’s Storm Petrel which is audible throughout all the recording. More info in Wikipedia, eBird and Fuglavefurinn
Background noise is a rumble noise from a trawler. It was almost constant noise all the time we stayed on the island. Even though I did not see any ship around the island, the air was vibrating with this deep rumble engine noise.
It seems like I need to spent much more time in this remote island and record its biological soundscape. It change over the day, every months, spring, summer, autumn and winter. So just 24 hours is not enough. Same as with other nearby islands, which host different bird species and different soundscape.

It is rear now a days to discover new places without traffic or engine nose. I found one in June 2019. It was at Fellströnd, in the northwest of Iceland. That means I have natural silence for more than a one hour. It is a south part of a peninsula which only have gravel roads and no shopping service so motorist are normally not driving there for pleasure.
Less human traffic means more biodiversity. It thrives better in places with less farming and fast driving cars. One roadkill can as well mean a death of the whole family. Car covered with smashed bugs means less food for birds… and so on. This is clearly visible and audible in those areas which have „industry“ farming and lots of fast driving traffic.
No traffic, or engine noise, means more natural silence and more transparent soundscape. Therefor it is very interesting to listen to this recordings. It is even possible to hear sheep footsteps far away and detect what bird species are in the area, even far away. In fact it is possible to analyze the situation of the biodiversity.
This is a high gain recording, recorded at +50dB. Gain was then increased in post about +25dB, normalized at -8dB and gently NR.
This is a part of 10 hour recording. This part was recorded between 7 and 8 in the morning at 21st of June.
Many bird species are audible in this recording. Black tailed Godwit, Common Redsank, Whimprel, Red necked Phalarope, Eurasian Oystercatcher, Common Ringed Plover, European Golden Plover, Dunlin, Raven, Redwing, Purple Sandpiper, Meadow Pipit, Geylag Goose, Whooper Swan, Red Throated Diver and Common Eider. I am almost sure I have not counted them all.
You can hear sheep footsteps which was though far away, also birds wing flaps as a low rumble noise.

Svartárkot means “Black River Croft” and is a working sheep farm at the southernmost part of Bárðardalur valley in northern Iceland. It lies on the western bank of Svartárvatn lake, at the southernmost point of Fljótsheiði heath, around 400 meters above sea level, at the foot of the Ódáðahraun lava, the wildest uninhabited lava interior of Iceland. To the south, a wilderness extends all the way to Vatnajökull glacier, the largest ice-cap in Europe. To the south and east lie the rugged uninhabitable areas o the highlands, the domains of glaciers and lavafields. A colourful cultural history is to be found further down the valley towards the lowlands. Svartárkot has been inhabited through most of Iceland’s history and can be seen as a symbol for the interplay between humans and nature, human habitation and wilderness. In addition to sheep, the farmers at Svartárkot maintain a trout fishing business by selling fishing licenses and home-smoked trout and arctic char. They are also experienced guides with a vast knowledge of the interior preserved through generations, and lead both hiking tours and mountain jeep excursions(source).
I was at Svarárkot farm in late May 2018, with Bob Mcguire who was collecting bird sounds in associate with the Cornell Lab of Ornithology, Macaulay Library of Natural Sounds. Farmers were busy in lambing and birds in mating, especially Barrow´s Goldeneye. This duck is not common in Iceland. They are mainly found in NE Iceland, around lake Mývatn and at Svartárkot farm, probably because farmers make nesting boxes inside the barn´s walls.
I and Bob spent maybe two or three hours at Svartárkot recording birds, sheep and soundscapes. Just before we were leaving the place, I put up my rig between the lake and the sheep sheds and started recording. The outcome was the following recording.
It starts peacefully in calm weather. Behind the microphones is the sheep sheds and in front is the lake with most of the birds that make sounds in this recording. Nosiest are the Barrow´s Goldeneye with its strange male´s „ticking“ attracting sound. There are also other birds like Raven, White Wagtail, Dunlin, Arctic tern, Common Ringed Plover and Whimbrel. The farmer is driving on four wheeler between the buildings on the farm and suddenly the wind gets stronger until it was almost impossible to continue the recording.

Remote islands are interesting places. Almost every island has it’s own ecosystem which can be interesting to record. One of those islands is Elliðaey, which is a part of Vestmannaeyjar islands, south of Iceland.
I got an opportunity to go there on a 24 hours trip with Bob McGuire, which is recording birds in association with the Cornell Lab of Ornithology, Macaulay Library of Natural Sounds.
I am not a specialist in the ecosystem in Elliðaey so I will not say much about it here. It is slightly different between each island in the region and the bird species can be different from cliff to cliff
Our main target in Elliðaey was European storm petrel and Leach’s storm petrel. Bob was collecting individual calls and songs but I was going to record hours of ambiances. The bird colony gives a strong smell as usual, but this island also has a strong smell of sheep. For decades there have been several landowners and farmers from Heimaey island who keep there several dozens of sheep during the summertime.
Puffins have been in a very difficult situation for many years, especially south Iceland and Vestmannaeyjar islands. Mainly because some annually rhythm changes in the ocean biosphere. That situation was visible in Elliðaey. Probably more than 50% of the Puffins burrows were empty and abandoned and dead chicks were also visible around.
Not all birds have difficulties and many other bird species also live and breed in the island; Atlantic Puffin, Manx Shearwater, Leach’s Storm-petrel, European (British) Storm-petrel, Great Black-backed Gull, Lesser Black-backed Gull, Herring Gull, Black-legged Kittiwake, Northern Fulmar, Common Eider, Common Murre, Black Guillemot, Common Raven, European Starling, White Wagtail
As soon as we arrived I quickly found locations for the recorders and then we walked around in the bumpy landscape for other locations. We were early in the breeding season, 4th of June, so we were even not sure if birds we were going to record, like European storm petrel, had already arrived. What surprised me most was the silence in the interior island. No sound from the ocean waves or cliff birds, only wing flaps from busy birds above our heads, mostly puffins. But there was also a low rumbling noise, which filled the air and was difficult to locate. It took me time to figure out what it was, but it was from ships somewhere far away on the ocean, so far I could not even see them in the horizon. This noise never stopped when I was awake. It was just differently loud during day and the night, and of course louder when ship passed close to the island.
The following recording was made just before midnight on a hill south of the hut in the island, located almost in the middle of a puffin colony.
It is mostly puffins wing flaps, when they fly over, landed close by the microphones and sometimes a „spray & splash sound“ when they poop
Later that night both Leach’s Storm-petrel, European Storm-petrel surprisingly arrived to the island. But that will be for another blog.

Ásbyrgi has a fantastic soundscape. It is one of the wonders of nature, a forested horse-shoe shaped canyon in Oxarfjordur. Asbyrgi is a part of Jökulsárgljúfur, within the Vatnajökull National Park.
I was there recording over night for ten hours 1st. of June 2018 . I don´t know if it was the time of the year, or something else, but the cliffs were very quiet this night. Usually I have been there later in June and July and the Fulmar in the cliffs have been noisier.
It was around 8 o´clock in the morning, just before the tourist traffic arrived that the soundscape in the canyon changed. It was like the whole biosphere woke up with lots of birds and insects activity. The following recording is the last 30 minutes that day before the soundscape was ruined by traffic noise and yelling tourists. Several bird species are in this recording. Northern Fulmar, Common Snipe, Eurasia Woodcock, Whimbrel, Red-Necked Phalarope, European golden Plover,  Pink footed Goose, Eurasian Wigeon, Eurasian Teal, Redwing, Common Redpoll, and Snow Bunting.
Here you can also listen to older posts from Ásbyrgi: Fairy in Ásbyrgi and Botnstjörn pond in Ásbyrgi.
