Svínafellsjökull icefall lay in a valley between Svínafellsheiði and Hafrafell. It is an icefall from Öræfajökull which is the highest mountain/glacier in Iceland around 2109 meters high.
I spent several nights beneath Svínafellsjökull icefall in May, both 2015 and 2016, recording 8-10 hours overnight recording. I was always trying to capture iceberg breakdown into the glacier lagoon, because last time I record it in 2014 it was disturbed with huge tsunami.
But most of the breakdown was probably somewhere between 1300-1700 meters, high in the mountain.
Anyway, during the night when traffic goes down and the weather was calm, it was always interesting to listen to the glacier in the „silence“. It starts like a thunder with low frequency rumble, high in the mountains. Then a strange „white noise“ falls slowly down the the wally, all the way to the end of the icefall toe. I am still not sure if it was an echo from the mountain or some crawling sound from the glacier. But it was so slow that I am almost sure that it is was not an echo from surrounding mountains.
But this is not what you will hear in the following recording. After one of this overnight recording in 15th of May 2016 I decided to record near to a frozen pond close to the glacier’s toe. The time was around eight o´clock in the morning so the tourist traffic had not began to disturb the soundscape. The temperature was just below zero, but the morning sun was already melting the ice in the area. The soundscape was amazing. With closed eyes it sounds like a busy place with bunch of small elves. Small trickle, ticks and cracks makes the soundscape worth to listen and to record.
At 17th minute the glacier start to crawl and then again one minute later with low frequency rumble.
Quality open headphones are recommended while listening at low to mid level.

An outwash plain, also called a sandur is a plain formed of glacial sediments deposited by meltwater outwash at the terminus of a glacier. As it flows, the glacier grinds the underlying rock surface and carries the debris along. The meltwater at the snout of the glacier deposits its load of sediment over the outwash plain, with larger boulders being deposited near the terminal morraine, and smaller particles travelling further before being deposited. Sandurs are common in Iceland where geothermal activity accelerates the melting of ice flows and the deposition of sediment by meltwater.
The original sandur from which the general name is derived is Skeiðarársandur, a broad sandy wasteland along Iceland’s south-eastern coast, between the Vatnajökull icecap and the sea. Skeiðarársandur is the largest sandur in the world, covering an area of 1,300 km2 (500 sq mi). Volcanic eruptions under the icecap have given rise to many large glacial bursts (jökulhlaups in Icelandic), most recently in 1996, when the Ring Road was washed away (minor floods have also occurred since then). This road, which encircles Iceland and was completed in 1974, has since been repaired. The 1996 jökulhlaup was caused by the eruption of the Grímsvötn volcano, with peak flow estimated to be 50,000 m3/s (1,800,000 cu ft/s) compared to the normal summer peak flow of 200 to 400 m3/s (7,100–14,100 cu ft/s). Net deposition of sediment was estimated to be 12,800,000 m3 (450,000,000 cu ft).
The main braided channels of Skeiðarársandur are the Gígjukvísl and Skeiðará rivers, which incurred net gains of 29 and 24 cm (11.4 and 9.4 in) respectively during the 1996 jökulhlaup. In the Gígjukvísl there was massive sediment deposition of up to 12 m (39 ft), which occurred closest to the terminus of the glacier. The erosional patterns of Skeiðarársandur can be seen by looking at the centimeter-scale elevation differences measured with repeat-pass laser altimetry (LIDAR) flown in 1996 (pre-flood), 1997, and 2001. Of the overall deposition during the 1996 jökulhlaup, nearly half of the net gain had been eroded 4 years after the flood. These two rivers on the sandur display drastically different erosional patterns. The difference in sediment erosion can be attributed to the 2 km (1.2 mi) wide trench near the terminus where the Gígjukvísl flows, in contrast with the Skeiðará, which has braided flows directly onto the outwash plain. The Gígjukvísl river is where some of the highest level of sediment deposit occurred and also where the largest erosion happened afterward. This indicates that these massive jökulhlaup deposits may have a large geomorphic impact in the short term, but the net change on the surface relief could be minimal after a couple years to a decade. (*Wikipedia)
This recording is just 23 minutes of 1o hours long overnight recording. It is very quiet and highly amplified. The microphones are unexpected located near to Northern Wheatear´s nest which is between stones in old ruins in the middle of Skeiðarársandur. You can hear wing flaps and some kind of a conversation between the birds and the youngsters. The birds sounds a little bit out of phase but that could be either because the bird is mostly behind the microphones, or the stone wall, or because the fury windshield was still soaking wet after heavy rain one hour earlier.
At 1:35 min a thunderous boom sounds from glacier in distance. During the recording the weather changed from calm to be windy.
Quality open headphones are recommended while listening at low to mid level, or in speakers at low level.

Sögur af Skeiðarársandi 1. hluti

Hér er á ferðinni rúmlega 20 mínútna löng upptaka sem er partur af 10 klst langri næturupptöku frá því 29. maí 2016 á Skeiðarársandi. Á sandinum svo til miðjum er hlaðin rúst sem líklega hefur gengt því hlutverki að vera fjárrétt áður en árnar á sandinum voru brúaðar. Í upptökunni má heyra að í vegghleðsluni er hreiður Steindepils. Hann pirrar sig eitthvað á óboðnum gesti þessa nótt, hljóðnemunum, en virðist svo líka eiga einhver samskipti við unga sína með lágværu tísti eða muldri. Heyra má að á þessum rúmu 20 mínútum að veðrið breytist frá því að vera logn yfir í rok.
Mælt er með því að hlusta á upptökuna í góðum opnum heyrnartólum og á miðlungs- lágum hljóðstyrk.

I think I don‘t need to present the nature reserve in Flói in many words. It is a wetland / moors in south of Iceland. I have already published in this blog several hours of „Flói recordings“.
Last spring was cold, wet and windy so I did not spend much time there. But in June, I stayed there for two nights while I recorded several hours of recordings during the nights.
As usual I fell in to sleep in the field during that time, so I did not know what I was recording. Last week when I was searching trough the recordings, I noticed some interesting moments.
At 14th of June the overnight weather forecast was nice and I started to record at midnight. Between 2 and 5 in the morning the wind went down so the field got „quieter“ for far distance sound waves.
I put up Rode NT1 in NOS in the same place as usual and pointed them to north. The soundscape is always spectacular in this place.
This soundscape is probably not what everyone would hear by bear ears. The recording is highly amplified. In this circumstances and Rode NT1, I normally adjust the gain on the recorder between 54-58dB. In this particular recording the gain is increased again in post about +24 dB so the peak level in one moment (at 13:16) reach 0dBf.
Many bird species are audible in this recording like Red throat Diver, Common Snipe, Golden Plover, Dunlin, Whimbrel, Gull, Arctic Tern, Northern Wheatear, Greylag Goose, Whooper Svan, Meadow Pipit and other bird species I have forgotten, or can’t name. Other audible animals like horses and sheep’s are there too.
Background noise is mostly from the Atlantic ocean’s waves along the south coast behind the mics. Then as usual, traffic noise and sometimes a party music somewhere in the county.
Quality open headphones are recommended while listening at low to mid level, or in speakers at low level.

Flói 2015. 1. Hluti

Hér er á ferðinni upptaka úr friðlandinu í Flóa frá því á laugardagskvöldi og sunnudagsmorgni 14. júní 2015. Eins og fyrri upptökur úr Flóa sem finna má hér á síðunni eru hljóðnemarnir ávallt staðsettir á sama stað við sömu tjörn norðan við fuglaskoðunarhúsið.
Í upptökunni má heyra í ýmsum fuglategundum. Má þar nefna lóm, hrossagauk, heiðlóu, lóuþræl, spóa, máfa, kríu, steindepli, grágæs, álft og þúfutitling. Þá heyrist lika í hestum og kindum.
Bakgrunnssuð er einkum brim meðfram Suðurströndinni og einkum við Ölfusárósa. Svo berst hávaði frá bílum og partítónlist einhvers staðar í sveitinni.
Mælt er með því að hlusta á upptökuna í góðum opnum heyrnartólum og á miðlungs- lágum hljóðstyrk.

Whatever the mainstream media says, the Paris talk COP21 was a fraud. The outcome was almost nothing, just promises. For me and many others is it too late. The chain reaction has already started so radical actions was needed at last sixteen years ago.
Paris talk was tailor made for investors, corporations and politicians with different needs, probably to make different outcome from previous conferences.
I have wait for political actions all times since beginning of this century so I was really hoping for radical actions after COP21.
The only thing that Icelandic politics brought from COP21 was mostly a nonsense. Icelanders were already doing most of the “solutions” for other reasons. Icelanders will just plant trees and fill up drainage ditches to restore swampland. When investors are ready somewhere in the future, Icelanders will change fossil fuel cars into electric cars.
At the same time Icelanders will increase tourism, even though extreme growth in tourism last decade has already damaged the nature with following pollution and intrusion. Icelanders will also keep on making cheap power for antitrust corporations by building more polluting power stations. They are even going to search for oil well in the North Atlantic ocean.
So as so many earthlings Icelanders intend to continue their greedy and polluting lifestyle.
We are in War against Mother nature like we are all brainwashed by Sauron . We are not only polluting the earth´s atmosphere with poison gasses. We are also polluting the ground, the oceans and fresh waters with dangerous materials and gasses. Irritating audible noise is now everywhere, from the sky, on the surface and in the ocean.
Unpolluted space on our planet is now rarer than gold, in fact more valuable too.
I want to dedicate the accompanying recording to our foolish lifestyle. It was recorded on Mosfellsheiði, east of Reykjavik 25th of July 2013. It should be a quiet place, far away from busy roads in beautiful open landscape. But instead a rumbling noise filled the air from all directions. The recording contains “fossil fuel cars and air traffic”. But the loudest steady noise comes from Hellisheiðarvirkjun, a geothermal power station in more than 10 km distance. It normally blows huge amount of gases into the atmosphere. It is mostly hot steam but is mixed with toxic gases like carbon dioxide (CO2), hydrogen sulphide (HS) and also substantial quantities of hydrogen (H2). Other gases such as nitrogen (N2), methane (CH4) and argon (Ar) are in the gas mixture, but in lesser extent.

Erum við heilaþvegin af Souron?

Loftslagsráðstefnan í París COP21 var mér mikil vonbrigði. Ég hafði vonast eftir mjög rótækum aðgerðum STRAX, en niðustaða ráðstefnunnar varð aðeins í grófum dráttum sú, að fyrirtæki og fjárfestar þurfa að huga að í lotslagsmálum á næstu árum. Það er einfaldlega of seint.
Enginn þorir að takast á við vandann. Menn ætla bara að bíða og sjá hvort það sé nauðsynlegt að gera eitthvað og vonast svo til að tæknin bjargi öllu. Flest okkar hafa séð hversu skelfilegt ástandið þarf að verða svo menn taki nýja stefnu. Nægir þar að nefna mengun í iðnaðarborgum Kína. Fátt bendir til annars en að ástandið verði eins á heimsvísu. Það er því eins og mannkynið sé heilaþvegið af “Sauron
Framtíðn er því ekki beinlínis til að gleðjast yfir. Því vill ég tileinka upptöku hér fyrir neðan viðfangsefninu. Meðfylgjandi mynd er tekin á upptökustað. Allt virðist þar í fljótu bragði óspillt og ómengað. En það er ekki allt sem sýnist. Í loftinu er óvenju mikið af óheppilegum ósýnilegum gastegundum af mannavöldum eins og frá Hellisheiðarvirkjun.
Hljóðritið gefur aðeins til kynna hljóðmengun á stað þar sem ríkja ætti “þögn” ef mannfólkið hefði haft vit og rænu á því að þróast í sátt og samlyndi við Móður náttúru.

My favorite recordings are those who are many hours long. Even in places where I hear „nothing“, I will more often end up with expressively moments. Here is one of these moments when curious sheeps are sniffing, licking and biting the microphones. Not very interesting, but anyway the loudest part of seven hours long recording. It was recorded in Álftaver, in the south east south of Iceland, around midnight, 4th of June 2015.

Forvitnar kindur

Mitt skemmtilegasta viðfangsefni eru langar upptökur úti í náttúrunni. Jafnvel þó fátt makrvert heyrist, þá er oftar en ekki eitthvað áheyrilegt í þessum upptökum. Hér er ein slík uppákoma þegar rolla og lambrútur snuðra við hljóðnemasettið. Þetta er ekki merkileg upptaka en engu að síður háværasti parturinn úr sjö klukkustunda langri upptöku. Þessi hljóðpartur var tekinn upp um miðnætti í Álftaveri þann 4. júní 2015.

The 10th of July 2015 I visited Ásbyrgi national park, in the north east Iceland.
I arrived around 9 pm. The weather was rather cold, with light drizzle rain. However there was a sport game on the old camp side held by the local community. Calls, yell and sheers from audience sounded fantastic in the echo from the surrounding cliffs. Mixed with the birdsong from the forest and the cliffs above it sounded like I was in another world.
I found a good place to record this amazing soundscape.
Soon I noticed a boring noise in the background from petrol power generator so the recording was shorter than I hoped .
When I came back to the car park the sport game was finished and the people were leaving the place. I heard someone in the crowd playing on Mbira thump piano. It came from female in traditional dress. Her instrument sounded nice in this place, so I enjoyed listening while I was packing my gear in the car.
Some Icelandic male in the crowd called after her: ‘Where are you from?“
„I am from everywhere“ she repleted.
Funny answer, I thought and started to listen to the conversations. Why not record her while she was playing?
She gave me a permission, so we took a walk to Botnstjörn pound in the bottom of Ásbyrgi.
Her name is Jessica Rose, with nickname Fairy.
I did not dare to ask her about her nationality, but her English was from the west, maybe from Canada, or north east USA. She was traveling in Iceland with her sister and two friends.

Fairy in Ásbyrgi

Um miðjan júlí 2015 kom ég við í Ásbyrgi. Ég hafði gefið mér nægan tíma þar árið áður svo ég ætlaði ekki að að eyða þar miklum tíma heldur fara á aðra staði í þjóðgarðinum sem ég hafði „hljóðstað“ á.
Ég kom á bílastæðið í botni Ásbyrgis um kl. 21. Á gamla tjaldsvæðinu stóð yfir íþróttamót. Það var því óvenju mikið af bílum og fólki á svæðinu. Hvattningarköll áhorfenda bergmáluðu sérkennilega milli klettanna í bland við fuglasöng úr skóginum og fýlahjal ofan úr klettunum. Ég rauk því til og fann mér upptökkustað. En það leið ekki á löngu að suð frá bensínrafstöð á keppnissvæðinu fór að pirra mig. Upptakan var því styttri en til stóð.
Þegar á bílastæðið var komið var fólk að streyma af mótssvæðinu. Heyri ég þá að einhver spilar á þumalpiano sem hljómaði skemmtilega á þessum stað. Var þar á ferð dama að nafni Jessica Rose sem vildi láta kalla sig Fairy. Var hún þarna í félagsskap með systur sinni og tveimur öðrum vinum á ferð um landið.
Ég stóst ekki mátið. Ég fékk leyfi hjá henni til að taka tónlist hennar upp og var það gert á pallinum við Botnstjörn.

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.
