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.

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.

Nothing is closer to a perfect experience as being alone in the wilderness, as far from any machines or human activity as you can. And when it is in cold or high altitude with no, or very quiet animal spices, your sense of organ, automatically starts to detect many things you may have never noticed before.
This is one of the things that make field recording in quiet environment so exciting. When you ignore the noise in your head and start to use all your senses, you suddenly noticed another level of sonic world. As a former touring cyclist I spent many weeks every year on the Icelandic highland. I was mostly alone so I got a great opportunity to listen deeply to this quiet soundscape.
Most of this soundscape is just a sound of wind and water and sometimes birds, sheep and gnats in distance.
Following recording contains this typical Icelandic highland soundscape as I remember it. It is so quiet that even the best modern recording equipment can barely capture it and lot of people would not hear anything in such places.
This recording sounds really nice in full quality, but as in mp3 format I am not sure if it interest online listener. Most PC soundcards and headphones do not have the sufficient quality to make it interesting. But anyway it is now online. This is, by the way, my favorite recording material.
The recording was captured between 8 and 9 am 26th of June 2014 in Vesturöræfi moorland, a huge open landscape east of Iceland in 600-800m above sea level. It was “early spring” so there was still a huge of snow.
The beat, or ticking sound, is a drops falling of strew down about 1cm in a small puddle (the picture above).
Some of the pink noise in the background is coming from the waves on the lake “Hálslón” (behind the microphones) and other flowing water in the area, so it is not only amplified noise or mic noise.
Audible birds are mostly Dunlin and in distance Golden Plover, Whimbrel and Northern Wheatear.
Thanks to the Friends of Vatnajokull who made this recording trip possible.
Quality headphones are recommended while listening at low level.

Droparnir falla á Vesturöræfum

Hér er á ferðinni upptaka frá Vesturöræfum vestan Snæfells. Þögnin var alger en þó mátti heyra í einstaka fugli. Það var tilvijun ein sem réði því að af þessari upptöku varð. Ég rölti um volteldissvæði nærri Klapparlæk rétt ofan við flóðlínu Hálslóns. Ég rak þá augun í vatnsdropa sem láku af strái í gríð og erg í lítinn poll þar sem þeir flutu og köstuðust til á vatnsfletinum í skamma stund.
Við að leggjast á fjórar fætur þá mátti greina taktfast ,,tikk” hljóð sem ég hlóðritaði í um klukkutíma.
Afraksturinn var að hluta til upptakan sem hér má heyra.
Fuglin sem helst heyrist í er lóuþræll, en í bakgrunni má heyra í lóu, spóa og steindepli.
Bakgrunnssuð er að hluta til frá öldugangi í Hálslóni og seitlandi leysingavatni í nágrenninu því enn var mikill snjór var á svæðinu þó kominn væri 26. júní.
Ekki er víst að allir geti notið þessarar upptöku þar sem hún þarf helst að hljóma í fullum upptökugæðum og góðum tækjum. En hér þó á ferðinni það upptökuefni sem heillar mig mest, það er það sem flestir mundu kalla ,,þögn”.
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.

It is shocking how hard it is to find quiet places. Our planet is completely rumbling of humans machines. It does not matter where it is, in the ocean on land or in the sky. The situation just goes worse every year.
But „quiet nature“ is not „nothing“. It can be a glorious soundscape with lot of details that can be really wonderful to listen. That is one of the reasons why „quiet nature“ is my favorite recording material. It is hard to find and always difficult to record.
It is a luck to get a nice recording of ¨quiet nature“ It must be all in one, right place, correct time and specific calm weather.
Most of Iceland is without trees or forest. It is mostly bare open landscape so sound can travel in long distances. Sometimes is it possible to hear traffic up to 30 km away. So just one car can cover a huge area with noise pollution for a long time.
In October 2013 I was recording over night in Stafholtsunga, west Iceland. I located the microphones in a ditch to avoid traffic noise as much as possible. But traffic noise all over the county and air conditioner at nearby farm infected this recording most of the time.
The recording starts between 6 and 7am.
If you have quality headphones and sound card you will hear many other things than noise. You will hear in several bird species like raven, starling and swans and birds activity near the microphones. Also barking dog, sheep and horses in distance. You will hear some dripping sound from the groundwater in the ditch. Gust will also gently weep grass and nearby bush.
Quality headphones are recommended while listening at low level in relaxed position.

Dögun í Stafholtstungu, fyrsti hluti

Það er orðið skelfilegt hversu erfitt er að komast í „náttúrulega þögn“ án vélrænna hljóða frá manninum. Það skiptir engu hvar maður er og á hvaða tíma dags, hávaðinn er alls staðar frá vélum mannsins, í sjónum, á landi og í lofti.
En stundum kemst maður í ágætis færi við „þögula náttúru“ svo langt sem það nær. Auðvitað mætti komast í þessa þögn fjarri mannabyggð en áskorunin er mest að ná þeim í byggð, enda er þar mjög margt áhugavert sem spennandi er að hlusta á án vélahljóða.
Þann 20. október 2013 var ég í Stafholtstungum í Borgarfirði. Setti ég hljóðnema í skurð svo að umferðin í sveitinni kæmi sem minnst inn á upptökuna.
Þarna má heyra ýmsilegt svo sem í húsdýrum, fuglum sem og ýmsu sem fer fram hjá flestum í dagsins önn.
Mælt er með því að hlusta á þessa upptöku í góðum heyrnartólum og á lágum hljóðstyrk um leið og slakað er á í þægilegum stól eða rúmi.
