Iceland’s electricity is produced almost entirely from renewable energy sources: hydroelectric (70%) and geothermal (30%). Less than 0.2% of electricity generated came from fossil fuels (in this case, fuel oil). In 2012 there was no wind power installed in Iceland. Electricity production increased by 24 MWh/person from 2005 to 2008, an increase of 83%.
According to Statistics Iceland the total electricity consumption was 7,958 GWh in 2002, 11,480 GWh in 2007, and 17,068 GWh in 2012. The aluminum industry in Iceland used 71% of produced electricity in 2011.
The electricity supply and consumption were equal in 2008: 53.1 MWh per inhabitant when the European union (EU15) average was 7.4 MWh. Iceland’s consumption of electricity was seven times higher than EU 15 average in 2008. The domestic electricity supply promotes use of electricity.
The Icelandic electricity market is geographically isolated. The market was closed for competition prior to 1 July 2003. Almost all electricity was supplied by Landsvirkjun and sold through regional distribution companies. Landsvirkjun had a monopoly position on investment in generation. Full market opening began in 2006 e.g. with the opportunity to switch supplier. Contracts for large scale energy users were in general long term, up to 30 years with options for extension.
Landsvirkjun, the largest electricity producer, had 76% annual production in 2007.The majority of the electricity is used in industry, mainly aluminium smelters and producers of ferroalloy. Landsvirkjun does not participate directly in the retail market for households and smaller businesses. In the retail market the main companies are RARIK, Orkuveita Reykjavíkur and Hitaveita Suðurnesja.The last two have also entered into the market for energy intensive users. The households heated with electricity, not many, receive subsidies to make their heating costs comparable to hot water heating. (Wikipedia) .
The following recording was recorded at Skóey island in Hornarfjörður fjord under a powerline “Byggðalína”. It is a 132kV powerline which connects all the regional and local electrical grids together and stabilizes the whole electrical grid in Iceland. The structure is in most parts over thirty years old and for the last several years it has been quite overloaded.
The recording was in 24bit/48Khz. Behind the aggressive electrical sound is a typical calm, quiet wetland soundscape with rumbling background noise from the ocean shore not far away and traffic.
When the recording is inspected in specrogram it shows the sparks fill the whole frequency spectrum of noise, or up to 24Khz (see picture). It would have been interesting to record this sparking sound at 192kHz because the whole microphone frequency range is up to 50Khz. That is not all, because the air is massively loaded with EMF/radiowaves, from 50Hz up to several hundred kHz. The strong radio signals travel long distances and make it almost impossible to record clean spaceweather signals with VLF receiver without human electrical noise pollution.

World Oceans Day takes place every 8 June. It has been celebrated unofficially since its original proposal in 1992 by Canada’s International Centre for Ocean Development (ICOD) and the Ocean Institute of Canada (OIC) at the Earth Summit – UN Conference on Environment and Development (UNCED) in Rio de Janeiro, Brazil.[1] The Brundtland Commission, i.e. the World Commission on Environment and Development, provided the inspiration for a global oceans day. The 1987 Brundtland Report noted that the ocean sector lacked a strong voice compared to other sectors. At the first World Oceans Day in 1992, the objectives were to move the oceans from the sidelines to the center of the intergovernmental and NGO discussions and policy and to strengthen the voice of ocean and coastal constituencies world wide.
The Ocean Project, working in partnership with leading organizations from all sectors, including the World Ocean Network, Association of Zoos and Aquariums, and many others in its network of 2,000 organizations, has been promoting World Oceans Day since 2002 and together with World Ocean Network led a three-year global petition movement to secure official UN recognition. World Oceans Day was officially recognized by the United Nations in late 2008.[2]
World Oceans Day events are celebrated on 8 June, the closest weekend, the week, and the month of June. The day is marked in a variety of ways, including launching new campaigns and initiatives, special events at aquariums and zoos, outdoor explorations, aquatic and beach cleanups, educational and conservation action programs, art contests, film festivals, and sustainable seafood events. Youth have been playing an increasingly important role since 2015, including the development in 2016 of a World Oceans Day Youth Advisory Council (Wikipedia).
The following recording was recorded at midnight 29th of May in a wonderful weather nearby Hraunhafnartanga peninsula, close by the arctic circle.
Quality open headphones are recommended while listening at low to mid level, or in speakers at medium level.

For me nothing is as pleasant as laying in the grass on a warm summer day in good distance from human activity, looking at the sky and listen to the wind wipe the grass until I fall a sleep.
This is something I did the 30th of July 2017 when I decided to visit places I remembered as a child, almost 50 years ago. It was at my grandparents´ farmland, Efri-Brú, which they owned most of the last century.
About 2 km northeast of the farm is a place named Hvítingshæðir. There is an old ruin of sheep shield, surrounded in grass field and remnants of old fence. This sheep shield in Hvítingshæðir was one of three or four sheep houses in distance from the main farm buildings. These sheep shields were usually built in places where it was easy to mow and keep hey for sheep during the winter months.
There is not much going on in this recording. Many decades have passed since farming was in the area and most birds are quiet this time of the day. So gust is playing the main role in the recording.
This was one the first recording I did with my parallel MKH8020/8040 AB setup in Rycote windshield. It was recorded on four channels with 50dB gain and HPF at 80Hz.
Quality open headphones are recommended while listening at low to mid level, or in speakers at low level.

Á örfáum árum hefur ójöfnuður aukist gríðarlega á Íslandi, einkum frá aldamótum, þó upphafið megi rekja lengra aftur í tímann.
Eignir og auðlindir þjóðarinnar hafa sópast til örfárra einstaklinga. Nú er svo komið að aðeins 5% þjóðarinnar á jafn mikið og hin 95%. Ef nánar er farið út í þetta þá eiga 20% landsmanna 90% allra eigna og þar með eiga 80% landsmanna aðeins 10%.
Þessum ójöfnuði hefur verið stjórnað af orfáum ættarklíkum, eins konar Oligarch, sem hafa alla tíð komið sínu fólki til valda á Alþingi í „frjálsum“ kosningum. Það sem verra er, þeir hafa svo í gegnum tíðina komið sínu velvildarfólki í allar mikilvægar stöður í ráðuneytum og stofnunum ríkisins. Þessu fólki er svo ómögulegt að skipta út þó almenningur kjósi annað.
Þessar valdaklíkur eiga líka flesta fjölmilðana sem eru verulega litaðir af áróðri og heilaþvotti oligarkanna.
Eftir bankahrunið í október 2008 hefur spillingin í samfélaginu sífellt orðið augljósari þrátt fyrir að öllum fréttum og upplýsingum um slíkt sé haldið í lágmarki á fréttamiðlum oligarkanna. Fréttamönnum sem fara út í slikt, er sagt upp störfum eða þeir lögsóttir. Vísað er til alls kyns óljósra laga, kerfisvillna, þagnarskyldu eða málum einfaldlega ekki svarað.
En hægt og sígandi hefur spillingin samt sem áður verið dregin fram í dagsljósið. Þökk sé fólki sem hefur þor og þolinmæði til að berjast fyrir réttlæti, og vinnusömum fréttamönnum sem hafa þorað að leita sannleikanns. Samfélagsmiðlar hafa stöðugt minnt á einstök mál sem litlu óháðu fjölmiðlarnir kryfja til mergjar.
Ekki verður farið nánar út í einstök spillingarmál hér, en meðfylgjandi upptaka var tekin upp 4. apríl 2016 á mótmælum á Austurvelli þegar upp komst að þáverandi forsætisráðherra, Sigmundur Davíð Gunnlaugsson og spúsa hans, höfðu tengst aflandseyjareikningum. Hann sagði svo af sér daginn eftir þessi mótmæli. Þáverandi fjármálaráðherra Bjarni Benediksson, var lika flæktur í ýmiss konar brask en að vanda slapp með ótrúlegum hætti.
Nú þegar 9 ár eru liðin frá bankahruninu þá eru valdaklíkurnar sem ollu hruninu enn við stjórn á Íslandi. Þjóðin er tvíklofin. Annars vegareru það þeir sem vilja breytingar og bætt samfélag og svo hinir, sem láta stjórnast af áróðri, yfirgangi og græðgi oligarkanna.
Upptakan er góð áminning um að íslenska þjóðin þarf nauðsynlega að takast á við breytingar. Þjóðin verður að fara að tileinka sér jafnrétti, samkennd, jöfnuð og bræðralag.

First weekend of August I traveled to Ísafjörður in the northwest of Iceland. From Isafjörður I took a daytrip with a boat over to Hesteyri which is located in a nature reserve named Jökulfirðir.
The weather was splendid so it was ideal to bring the recording gear with me and record the atmosphere at Hesteyri. This time I brought with me my newest mic setup I built inside Rycote stereo AG windshield. It is a 40cm spaced AB rig (AB40), a two stereo channels with parallel MKH8020/8040, which is slightly angled outward (around °5).
In Hesteyri I record in several places in a small area. Two of them was on the beach where the waves gently plays the music on the coastline during the rising tide. One of this recording is posted here below.
The wind was about 3-6 m/sec, blowing parallel among the coastline so the wind hit only the other side of the windshield, not front of it.
I used MixPre6. The gain was at 50dB, High pass filter on MKH8020 was 120Hz and on MKH8040 80Hz.
The microphones were placed on tripod 60cm above the ground. During the recording the tide rise so in the end the waves went under the rig.
Background noise is mostly the sea waves further outside the fjord and rivers behind and allaround the fjord. Sometimes the boat is knocking on the pier, 200 m away on the left side.
In post I lower the gain -5dB on MKH8020 and rise the gain +5dB on MKH8040 to keep the audible gain between the mics close to be equal. Use again Hi-Pass filter at 100Hz to minimize wind rumbling noise. and then normalized all three audio clips to 0dB. No low pass filter or noise reduction was used.
Both MKH8020 and MKH8040 sounds pretty similar in this recording, so I guess someone will ask:“ Why use four mics when two seems to be fine?“ “ Why making this four channel rig with this expensive mics?“ The short answer is this. The 8020´s are detecting sound from all 360° while 8040´s is only detecting 180° front of the rig. So if there was something behind the rig, like traffic noise it would been clearly audible with 8020´s, but far less with 8040´s. At this time (in Hesteyri) it was only a silence behind the rig so this is not a ideal recording for omni – cardioid comparison.
Field recording is mostly „once in a time – moment capturing“. So having a two different stereo recording of the same event, it is more likely either recording is OK. Two different recordings also give several opportunities in post.

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.

The day after the Panama papers were published, people gathered together all over Iceland to protest against the government. At last, thee ministers in the parliament and two members in the Reykjavik city council was involved in the disclosure. All this folks were members in the two right wings, republican parties that have ruled the Icelandic Parliament since spring 2013.
The following recording is recorded at the „first day in protest“ when around 20 thousand citizens gathered together downtown Reykjavik in the front of the Parliament house.

Mótmæli gegn pólitískri spillingu og siðleysi

Það hafði legið í loftinu í heilan sólahring að kvöld hins 3. apríl 2016 yrði viðburðarríkt.
Þjóðin sat því límd við sjónvarpsskjáinn þegar Alþjóðasamtök rannsóknarblaðamanna sendu frá sér fréttaþátt um aðkomu íslenskra stjórmálamanna að skattaskjólum.
Þetta kvöld var stór hluti þjóðarinnar beinlínis tekinn í þurrt rassgatið. Fram til þessa hafði fjöldi fólks fylgt gömlu hægri hrunflokkunum í blindni en þetta kvöld upplifðu margir algert siðrof gagnvart þessum flokkum.
Það fór því svo að met var slegið í þátttöku í mótmælum daginn eftir þegar á milli 20 – 25 þúsund manns mættu á Austurvöll og kröfðust afsagnar Sigmundar forsætisráðherra og allra þeirra sem höfðu verið nafngreindir við að fela fé í aflandsfélögum. Þá var einnig krafist þingrofs og að boðað yrði til þingkosninga hið bráðasta.
Hljóðupptakan sem hér fylgir var tekin upp á fyrsta degi mótmæla framan við Alþingishúsið.
