Description: Interview with Dr Simon Linke on ABC Radio National about our research on acoustic monitoring of the Mary River turtle hatching in Queensland, Australia. This project is supported by the Mohamed bin Zayed Species Conservation Fund and based at Griffith University (The Australian Rivers Institute and the Queensland Conservatorium Research Centre).

Absolutely captivating story and sounds -- many thanks, much appreciated!

The FKISM Podcast - Episode 1: Lady Bay Reef

Three Butcher Birds throw melodies back and forth on a windy morning between storms. An Eastern Koel joins in midway along with the rest of the dawn chorus and frogs can be heard in the waterway nearby.
These field recordings are part of my time in the role of 'The Keeper'. The observer, the explorer, the maker. The Keeper is a live public art project featuring artists from Coolum Beach, Australia. Find out more at: www.keeperproject.com.au

Listening to Mary River Turtles Hatching

The South Asian river dolphin or, more commonly known as the Ganges river dolphin (Platanista gangetica) is an extremely elusive animal. Because they live in sediment-rich Himalayan rivers like the Ganges, they have limited sense of sight and therefore, rely almost exclusively on sound for navigation, foraging and communication.

Acoustic methods are therefore, one of the best ways to make sense of their ecology. It is however, very hard for us to hear their high frequency echolocation clicks but with a little adjustment, we can hear and appreciate an incredibly rare and vocal animal.

Enjoy!

Sounds of the Ganges: The Ganges river dolphin

The Ganges floodplain is truly a place of contradictions. It is known to have the highest density of people in the world, yet, one can still find enigmatic animals like the Gharial, Ganges river dolphin and the smolth-coated otters. 
The region is also infamous for loud and deafening sounds produced by honking vehicles and explosive music, whereas the same place can calm you down with its soothing and tranquil ambient sound and in some cases, absolute silence.

This soundtrack attempts to capture this truly odd place. The river, its dwindling wildlife and its people are inseparable in most ways. One needs to go through the incessant noise in the cities around the river to actually experience the calm that follows.

Put your headphones on as you travel from the heart of a noisy city and into the soul of the Ganges river.

Riverine Symphonies: Sounds from the Ganges

3 minute audio sample from the 190 minute nature soundscape recording; “Adirondack Lake”. Listen to the complete recording:
http://www.listeningearth.com/play/album/99AdirondackLake.php

The still waters of a small lake in the Adirondack mountains of northeastern United States reflect the first glimmers of the approaching dawn. The treeline and low hills beyond stand out against the paling sky.

In the dark, Bullfrogs and Peepers have been calling almost continually throughout the night. Now this amphibian chorus subsides as the light grows. As we listen from the lake edge, the air begins to shimmer with the delicate sounds of passerine birdsong. It emanates from nearby forest and drifts across from the far shores - White-throated Sparrows, Warblers, Olive-sided Flycatcher and Wrens. Hermit Thrushes give querulous calls, between bouts of sublime song. A coyote calls distantly, and later deer barks echo across the lake.

This is landscape recording - you can hear the scale of the place, as birdsong drifts over the lake and echoes off the treeline. This album takes us into a still morning of listening, as sunlight slants through drifts of steam rising from the waters.

first light - recorded as a part of the REVIEL 2020 Event for 'International Dawn Chorus Day': streams.soundtent.org/2020/streams/utc-8_mt-shasta

Reveil is a collective production by streamers at listening points around the planet. Starting on the morning of Saturday 2 May in South London near the Greenwich Meridian, the broadcast will pick up feeds one by one, tracking the sunrise west from microphone to microphone, following the wave of intensified sound that loops the earth every 24 hours at first light.

In 2020 Reveil featurea new streams from places where humans and non humans meet, in soundscapes often radically altered by the Covid-19 pandemic. Many of these these streams come from from homes and gardens as people make connections between the the domestic spaces where they find themselves.

Themes of connection and collective practices addressing changes in public space inform the program of extended radio projects that accompanies the Reveil broadacast. Supported by Arts Council England originally as a series of site specific commissions, these have become virtual projects that respond directly or oblquely to the current situation. They help to recollect kinds of sociability that have been lost and point to others on the way. This is imagined sonically as an acoustic commons in the making.

first light - REVIEL 2020

Revisiting some under-explored experiments in "self-directed" sonic systems from Design After Nature project in 2008.  An experiment in maximal minimal generative systems (most variety, from simplest system).

What if sound determined the conditions of it's unfolding? 

In this example a tap dripping controls its own playback.

Pseudocode: 

Play sample
Listen for onsets
If above threshold (probabilistically) 
- change direction and speed (as an inverse function of the frequency of strongest partial -- to create a simple homeostasis) 
- resynthesise N partials according to the original energy distribution at the point of onset detection.

This simple routine draws out and explores the latent rhythmic and spectral content of everyday sounds. Endlessly. 

Best listened late at night on headphones.

It has a of life of it's own that I find quite pleasing. But I have been living on my own for nearly 3 months now : )

Listen to an ecoacoustic story walk, designed to be heard as you imagine walking (or actually walk) along the foreshore in Geelong. The sound walk starts at Steam Packet Gardens and navigates Cunningham Pier and back, ending down Alexander Thompson Pier in front of the carousel. 
Listen to gain some fresh perspectives on Geelong, particularly from a watery point of view.
This is a half hour walk. If you do walk and listen on your phone- the Geelong foreshore is very accessible for all abilities. Be aware that you may be passed by a miniature tourist train on your amble.

Pelican Time Machine - Sounding The Bay

這幾個禮拜因為大潭藻礁的公投聯署，各方人士吵來吵去，但是除了網路筆戰，互相爭執之外，大家有聆聽過大潭藻礁水下的聲音嗎?
這個聲音檔，就是在大潭G2位置收錄的水下聲音，裡面的每一個"啪"聲，都是棲息在藻礁生態系中的動物發出來的，聽到這不知道如何計算的啪聲，大概也可以想像的到水下有多少發聲的動物。一般來說，我們只會在珊瑚礁生態系聽到這麼吵雜的寬頻啪聲，因為珊瑚礁有很多槍蝦，槍蝦就是這種寬頻啪聲的主要聲源。
在我還沒聽過桃園藻礁的水下聲音時，我也曾經認為那不就跟台灣西岸其他的海域生態差不多，受到混濁海水高度影響，應該很難說是個生物多樣性熱點吧。但經過這幾年，在中研院生多中心、東海大學、成功大學、特有生物研究中心的眾多前輩努力之下，發現到桃園藻礁生態系真的是非常的特殊，是全世界在淺灘上最大的一個藻礁生態系統，其育幼地的功能不只支撐著竹圍漁港與永安漁業等近海漁業，特殊的生態環境也造就了7600年的藻礁景觀。
更難想像的是，我過去在執行白海豚生態調查時，一直不相信白海豚會到桃園海域活動，但是透過漁民的通報以及陳昭倫老師的陸上觀察，確實證明白海豚的活動範圍延伸到桃園海域。後來，我們和民間單位合作，在桃園藻礁外海收集水下錄音時，也聽到鯨豚運用回聲定位聲音覓食、導航，顯示這個地方豐富的生態功能。
中油第三天然氣接收站，不只是其開發範圍可能會直接破壞藻礁，因為港口而必須興建的堤坊、棧橋，也可能會導致當地藻礁生態受到淤沙或海岸線侵蝕而影響。其實，在開發與營運過程，因為船隻航運、機具運轉而產生的高強度、或是持續性水下噪音，也都可能會衝擊藻礁生態系中許多魚類、無脊椎動物的生理與行為。雖然沒有人曾經做過水下噪音對藻礁生態系的衝擊，但從珊瑚礁和牡蠣礁的過去研究成果來看，珊瑚和牡蠣幼生會透過聆聽水下聲音來尋找適合棲息的環境，珊瑚礁魚類也會被健康的珊瑚礁聲音而吸引。
從珊瑚礁和牡蠣礁的例子來看，健康的生態系有良好的聲音景觀，海洋動物在播遷過程中，透過聆聽聲音訊息便能提高播遷之成功率，這是一種基於水下聲音的感知而達到生態恢復的過程。但如果藻礁附近有大量的水下噪音，改變了當地的聲景，會不會就算環境品質還在，但仍然間接降低的生態恢復力?
在聯署的最後階段，希望大家都可以從不同政黨的政治立場先退開，拿起耳機，好好地聆聽一下這一段大潭藻礁的水下聲音。對你來說，大潭藻礁在傳遞甚麼訊息? 你，又要如何回應?
