Last month I published hydrophone recording „Crawling glacier“ from the lagoon beneath Svínafellsjökul icefall.
The original recording contains two other channels with the sound above the lagoon.
It is not as clear in this short mp3 file as it is with headphones in the field, but during the recording it seems to be possible to hear the flow of the icefall though the valley. Its is a slow event. It usually starts high above in the mountain with rumbling sound and then slowly moves in a shock wave as a silk smooth „white noise“ though the valley all the way to the toe of the icefall. Regularly the ice moves faster in some places when the pressure get high. Then it cracks, some parts brake off and other just crawl faster which is usually audible for everyone.
This behavior of the glaciers is not often audible during the day because of traffic, wind or the clear sun which can easily disturb the sound waves in the air. Then it is also too slow for impatient listeners. Nights are usually the best time to hear this sound of the „flowing mass“. Changeable nature or different types of glaciers will also play a big rule how it acts and sounds.
Quality open headphones are recommended while listening at low to mid level, or in speakers at medium level.

It is a special feeling to stay close to a glacier. It’s like standing near a wast monster that is constantly moving, but very slowly. Everywhere around this flexible ice the gravity of the ice is visible. Glaciers usually have strong smell of fresh oxygen that glaciers have captured in ice and compressed in to locked bubbles for hundreds and thousands of years. This smell from the past is like from another world, probably because today has much more carbon dioxide in the atmosphere than it has been for 800 thousand years at least. Glaciers also make sounds, sometimes quite loud, from falling drops of water to earthquakes, but most of these sounds are not audible to human ears. Glaciers make constant sound in water which needs hydrophones to capture, as can be heard on the following recording. I can not say I have been lucky in recording glacier sounds in years past. I’ve always been at the wrong place at the wrong time when glaciers produce “big sounds”, but after many hours, and several days on the same spot, I got something interesting which is worth listening to.
One of those days was 5th of June 2015 when I was at the glacier lagoon neneath of Skaftafellsjökull glacier’s icefall. This lagoon is not big, probably around 500m squared, but the depth is around 80 meters so the soundscape beneath the surface can be pretty exhilarating when the glacier is crawling at the bottom of the lagoon.
I put two hydrophones in the lagoon and two microphones on a nearby hill and recorded there for almost fourteen hours. The gain on the recorder was almost equal on all channels, or around 48dB, and during these 14 hour session the soundscape was different mostly because the glacier surface melts differently during the day then during the night with different water flows into the lagoon. All the time the glacier was grinding the bottom of the lagoon so under the lagoon’s surface the soundscape was much nosier than above.
Then just before midnight the glacier did a “big move” (starts 25:00) which lasted for several minutes, crawling with cracking and scratching sound. The soundscape down in the lagoon sounds really strange and surreal, but the listener must keep in mind that sound travels much faster in water than in the air. The soundscape above the lagoon was different. It was possible to ‘feel’ or ‘see’ through the audio the movement of the whole Svínafellsjökull glacier icefall through the valley. But that recording will be for another soundblog.

Vatnajökull is the largest ice cap in Europe by volume (3,100 km³). Vatnajökull has around 30 outlet glaciers (icefall) flowing from the ice cap. Svíafellsjökull is one of them.
Glaciers are not a playground for everyone. They have its own weather system and the gravity force will destroy everything that get lost in the ice.
Two British students lost their lives 1953 in a storm which lasted for 10 days on the glacier. It was not until 2003 that some of their equipment was found, carried forward with the movement of the outlet glacier. No human remains were found.
Two German tourist have been missing since 1st of August 2007 when they were on a hiking trip on Svínafellsjökull. Nobody knows what really happened but it is most likely that they fell in a swallow somewhere on the glacier, but their equipment was found in a small valley, high in the nearby mountains.
All glaciers have been shrinking fast last decade. That can be easily seen at the end of Svínafellsjökull witch now has a big glacier lagoon that did not exist few years ago.
As glaciers the glacier lagoons can be also dangerous. Icebergs can suddenly fall off the icefall and make huge waves in the lagoon, also when icebergs turns around or brake down in a parts.
I got in touch of these forces when I was recording the lagoon under Svínafellsjökull, 23rd of May 2014. I hid the equipment from other tourist in a landslide nearby and about two meters above the lagoon surface. Two Aquarian hydrophones where placed in the lagoon and a pair of MKH20 was used to pick up the sounds above the lagoon. The idea was to record in two or three hours.
I was in another place with my second recorder to record a sound close by the glacier.
After one and half hour I suddenly hear a big „bang“ with a long powerful echo from nearby mountains. All the icebergs on the lagoon suddenly moved around as a beans in a boiling pot.
I ran to the recorder´s place on the other side of the lagoon. The bag with the recorder was floating between the Icebergs so it was no problem to locate it in the muddy water. I disconnect the battery and took it inside to dry it as fast as I could. But nevertheless, it had several malfunctions since this drowning.
I am not sure what really happened. The flood line does´t goes all the away to the recorder´s place. I think it is most likely that some icebergs pulled the recorder by the hydrophones into the lagoon.
Thanks to Sound Devices in US and the reseller in Iceland (Pfaff-Borgarljós and Bragi Kort) I got a new recorder for a very nice price. Most of the loss was then covered by the insurances.

Flóðbylgjan við Svínafellsjökul

Jöklar og umhverfi þeirra getur verið hættulegt þeim sem það ekki þekkjir. Jöklarnir eru síbreytilegir og hafa sitt eigið veðrakerfi. Því ber að umgangast þá með varúð. Skemmst er að minnast hvarf tveggja þjóðverja á Svínafellsjökli þann 1. ágúst 2007 .
Mér var það svo sem lika ljóst að jökullón geta verið hættuleg þann 23. maí 2014 þegar ég staðsetti upptökutæki við jökullónið neðan við Svínafellsjökul. Tveir Aquarian vatnahljóðnemar voru staðsettir ofan í lóninu og aðrir tveir MKH20 hljóðnemar ofan við lónið. Sjálfur fór ég með annað upptökutæki til að hljóðrita upp við jökulinn sjálfan.
En líklega er aldrei of varlega farið. Eftir u.þ.b. eina og hálfa klukkustund kvað við mikill hvellur frá jökulsporðinum sem bargmálaði í fjöllunum ofan við jökulinn. Stuttu síðar fór allt jökullónið á hreyfingu eins og iðandi suðupottur. Mér varð því ljóst að upptökutækið við lónið gæti verið í hættu. Hljóp ég því sem fætur toguðu að staðnum, en allt kom fyrir ekki. Tækið var komið út í lónið og flaut þar í tösku milli ísjaka. Eftir að hafa þrifið það og þurrkað kom í ljós að tækið hafði bilað varanlega eftir þessa sundferð.
Allt bendir til þess að ísjaki hafi dregið tækið í lónið á vatnahljóðnemunum því flóðlínan hafði ekki náð upp að staðnum þar sem tækið hafði staðið. En skaðinn var skeður sem leytist þó á endanum þokkalega farsællega þó tjónið hafi verið eitthvert. Með óútskýranlegum hætti vistaði upptökutækið upptökuna áður en það drukknaði. Það sem hér má heyra eru síðustu andartök tækisins.

Jökulsárgljúfur canyon in Vatnajökull National Park is situated in the north of Iceland near the river Jökulsá á Fjöllum. In the middle of Jökulsárgljúfur, between Dettifoss waterfall and Ásbyrgi canyon, is Vesturdalur valley.
Vesturdalur is mostly surrounded with steep cliffs with luxuriant flat bottom. Through the valley flows a small creek, Vesturdalsá, on its way to the river Jökulsá á Fjöllum.
The first week in June 2014 I arrived there on a foggy night and placed the microphones close beside the creek. The soundscape in the fog was particular. The rumble sound from Jökulsá River about 3 km away, filled the air with extreme murky mysterious power. But all around me was a beautiful bird song that followed me in to the sleep.
This recording is several hours long so it is most likely that more of this recording will be available online someday.
Thanks to the Friends of Vatnajokull who made this recording trip possible.

Vestudalur við Jökulsá á fjöllum

Þann 8. júní 2014 eftir miðnætti kom ég í Vesturdal við Jökulsárgljúfur. Talsverð þoka var á svæðinu svo skyggni var fremur lélegt. Mikil frðsæld var í dalnum enda mjög fáir á svæðinu. Fjölskrúðugur fuglasöngur kom úr öllum áttum, en loftið var þrungið drungalegum drunum frá Jökulsá á Fjöllum í austri. Áður en ég lagðist til svefns fann ég stað fyrir hljóðnemana við bakka Vesturdalsár sem liðaðiðst hljóðlega um dalinn.
Um leið og tækið var komið í gang leið ekki á löngu þar til ég var kominn í draumheima með notalegan fuglasöng í eyrunum næstu klukkustundir fram undir morgun.
Þessa upptöku má þakka samtökunum Vinum Vatnajökuls sem gerðu það kleift að af þessari upptökuferð gat orðið.
Mælt er með því að hlusta á upptökuna í góðum heyrnartólum og á lágum hljóðstyrk.

It was early morning 20th of May 2014, when I and my friend arrive in to the campsite in Skaftafell national park, after almost five hours drive from Reykjavik.
There was just several tents on the campsite so we could easily find a quiet place in distance from other tents. I placed the microphones 30 meters from the tent, started recording and fell asleep.
The following 25 minutes long recording is what happened next. It is nice soundscape of early spring in Iceland without noise from human activity.
Many bird species are audible in this recording. Common snipe, Whimbrell, Red-tailed Godwit, Common Redshank, European Golden Plover, European, Oystercatcher, Whooper Swan, Redwing, Meadow Pipit and Rock Ptarmigan. There are probably many other bird species audible in this recording which I have not a clue the names on.
The recording this morning was about 6 hours long so I will probably continue to publish more of it later one.
Thanks to the Friends of Vatnajokull who made this rercording trip possible.

Vor í Skaftafelli 2014

Það voru nokkuð þreyttir menn sem mættu á tjaldsvæðið í Skaftafelli rétt fyrir kl 4 að nóttu þann 20. maí 2014.
Fáir voru á svæðinu svo það var auðvelt að finna stað fyrir tjaldið. Áður en gengið var til náða voru hljóðnemar settir upp 30 metrum frá tjaldinu og upptaka látin ganga langt fram undir morgun.
Sú 25 mínútu langa upptaka sem hér fylgir hefst u.þ.b. 20 mínútum eftir að við vorum sofnaðir.
Á upptökunni má heyra í mörgum fuglategundum, þar á meðal í hrossagauk, spóa, skógarþresti, rjúpu, og álft sem og mörgum öðrum sem ég ætla að leyfa hlustendum um að þekkja og skrifa nöfnin á í ummælum hér fyrir neðan.
Þessari upptöku má þakka samtökunum Vinum Vatnajökuls sem gerðu það kleift að af þessari upptökuferð gat orðið.
Mælt er með því að hlusta á þessa upptöku í góðum heyrnartólum og á lágum hljóðstyrk.

I got a grant to record nature sounds in the Vatnajökull national park from the association “Friends of Vatnajökull”. It was not a trouble free trip, but anyway it was very instructive and I recorded many hours of very interesting and lovely sounds. Most of the recordings are long and unbroken. Some of them are up to 6 to 10 hours long so they contains many things I have never heard until now when I am registering the collection and searching for material to publish.
In 22nd of May I spent most of the day near Jökulsárlón glacier lagoon. I recorded around three hours in the lagoon with hydrophones. I was located close to the ejection because there it was most likely to catch some wild life activity.
When I started following recording the current was flowing out of the lagoon. Three or five seals were diving nearby between the icebergs which slowly were moving towards the ejection.
It was stunning when I put the hydrophones in the lagoon.
What a sound! It was much louder than I thought and was both stunning and frighten.
The several thousand years old ice was melting with cracks, screeches and scratching the bottom of the lake. Sometimes I could detect a deep rumble sound in a distance, probably when icebergs were scratching the bottom of the 200 meters deep lake. Comparing to all those loud sounds, everything was peaceful above the surface.

Hljóðin í Jökulsárlóni. 1. hluti

Ég fékk styrk s.l. vetur til að hljóðrita hljóðvist Vatnajökulsþjóðgarðs frá samtökunum  Vinum Vatnajökuls. Það gekk á ýmsu á meðan á því stóð en á endanum var ég komin með mikið af áhugaverðu og skemmtilegu efni. Mikið af þessum upptökum eru langar og ósltitnar eða 6-10 klst langar svo ég hef ekkert hlustað á fyrr en nú þegar ég stend í því að skrásetja upptökurnar.
Þann 22. maí var ég staddur við útfallið við Jökulsárlón og hljóðritaði undir yfirborði lónsins með vatnahljóðnemum. Bæði hljóð og hljóðstyrkur kom verulega á óvart. Þarna var aldagamall ísinn að bráðna með hvellum og ískri um leið og hann skrapaði botninn á leið sinni að útfallinu. Öðru hverju mátti heyra drunur einhvers staðar utan úr djúpi lónsins og stöku sinnum mátti heyra hljóð sem hugsanlega komu frá 3-5 selum sem syntu ekki langt frá upptökustaðnum.
Það var óneitanlega mun háværara niðri lóninu en á yfirborði þess.
