The source of a rhythmic sound coming from the southern ocean has been a mystery since the 1960's, when it was first heard by a submarine personnel.  It has taken 54 years, but the sound has been identified as an Arctic Minke Whale.  An international team of researchers deployed acoustic tags on these Arctic Minke Whales; this was the first time it had been successful.  No one had previously known that whales were there because of their unorganized movement throughout the high and low latitudes.  Because of this successful deployment of the tags, scientists will be able to interpret new acoustic readings better, and also understand more about the behavior of the Arctic Minke Whale.

I thought this article was very interesting because it had taken scientists so many years to find out where the noise had been coming from.  Not much is known about this particular species of whale, but now that they have been identified as the noise makers, scientists have been able to study their behavior more.  The technology that the scientists used is also very cool.  More and more is being learned about the earth and it's inhabitants every day, and this is just another piece to the puzzle of our world.
