Would You Like To Listen To The Deep Ocean? Here is your chance.

The underwater environment of the world’s oceans is fill with a variety of sounds.  Most aquatic animals use sound for communications between members of their species.  The reason for all this cacophony is that sounds propagates well in water and covers longer distances.

The following image shows an overview of dolphin presence at the ANTARES observatory during May 2010. In this case the indicator measures the strength of whistle content found in the acoustic data.
The underwater environment of the world’s oceans is fill with a variety of sounds.  Most aquatic animals use sound for communications between members of their species.  The reason for all this cacophony is that sounds propagates well in water and covers longer distances. The advance of modern technology causes the increase in anthropogenic sources of sound that affects the marine life.  There are multiple cases of whales beaching themselves that were recorded in recent years.  On the occasions listed below testing of mid-frequency to low-frequency active sonar was conducted in the area.
  • 1996: 12 Cuvier’s beaked whales beached in Greece
  • 1999: 4 beaked whales beached in the US Virgin Islands
  • 2000: 3 beaked whales beached in Madeira
  • 2002: 14 different whales beached in the Canary Islands
  At best, the whales hear the “clicks” and change their hunting grounds not returning to the same spot for a few years.  There is also evidence that they change their “song” and make it louder. This causes a lot of concern to the marine biologists around the world.  A new project called LIDO or “Listening to the Deep Ocean environment” has emerged recently.  It proposes to establish a first nucleus of a regional network of multidisciplinary seafloor observatories contributing to the coordination of high quality research in the ESONET NoE by allowing the long-term monitoring of Geohazards and Marine Ambient Noise in the Mediterranean Sea and the adjacent Atlantic waters.     You can listen to the marine sounds around the world on their site.  Please click on the link below.  This is quite a unique experience to be able to hear underwater sounds across the globe. http://www.listentothedeep.com/acoustics/index2.php?web=lidoearth&lang=en If you  wish to enhance your understanding of the underlying principles of underwater and engineering acoustics needed to evaluate the impact of anthropogenic noise on marine life, please attend ATI’s Underwater Acoustics for Biologists and Conservation Managers course that will be presented on October 17-20, 2011 in Seattle, WA.

  2. Wow! Thanks for sharing the link and this wonderful article post. By going to your website it was like i was the GOD. I could rotate the earth just using the mouse and drag it. Cool website anyways.

  3. Thanks for the link with the marine sounds and the great information provided, it’s a shame that we still are hunting whales instead of keeping the environment in normal conditions.

  6. Thanks for this useful information. I agree, animals under the ocean are using sounds as a medium of communications. Thus, they too understand from each other with out talking 😉

  8. Another successful deed of technology! It’s a very exciting to hear of a dangerous mammal’s echo of deep ocean! Thanks a lot for posting about this fantastic invention.

  11. Yes, I interested to read and want to learn about Deep Ocean. By reading this article I’d found some of my asking question about deep ocean. Carry on your nice information for us. Thanks 🙂

  14. The other day, while I was at work, my sister stole my apple ipad and tested to see if
    it can survive a forty foot drop, just so she can be a youtube sensation.

    My iPad is now destroyed and she has 83 views. I know this is completely
    off topic but I had to share it with someone!

  15. I blog often and I seriously appreciate your content.
    The article has truly peaked my interest. I am going to bookmark your site and keep checking for new information
    about once a week. I opted in for your RSS feed too.

  16. I enjoy what you guys are up too. This sort of clever work and
    exposure! Keep up the excellent works guys I’ve you guys to my personal blogroll.
