What's In A Whistle? Name-calling In The Ocean

Anyone who has swum with dolphins including the members of the Open Water Swim Club know the friendly whistles of the dolphins. "As you swim parallel to shore in Huntington Beach and Bolsa Chica [in Southern California], and many other places, their unmistakable whistles and clicks can be heard much sooner than when you can see them," says Steven Munatones who has been swimming the waters for 40 years. "They just make the ocean swims so much more fun and enjoyable. But the dolphins can get big and it is out in the ocean so when they come close, I keep my distance and never try to pet them. They are so fast and can maneuver so quickly, just watching them watch us with their big eyes is a great treat every time they swim by us."

Science Now reported that every dolphin has its own high-pitched whistle and an analysis of whistles recorded from hundreds of wild bottlenose dolphins confirms that the dolphins have names (whistles) for each other.

Even infant dolphins learn their individual whistles from their mothers and males friendly with each other copy each others's signature whistles.

"It's a wonderful study, really solid," says Peter Tyack, a marine mammal biologist at the University of St. Andrews. "Having the ability to learn another individual's name is … not what most animals do."

The Other Shore

The Other Shore follows world record holder and legendary swimmer Diana Nyad as she comes out of a thirty-year retirement to re-attempt an elusive dream: swimming 103 miles non-stop from Cuba to Florida without the use of a shark cage. Her past and present collide in her obsession with a feat that nobody has ever accomplished. At the edge of The Devil’s Triangle, tropical storms, sharks, venomous jellyfish, and one of the strongest ocean currents in the world, all prove to be life-threatening realities. Timothy Wheeler’s documentary brings Diana Nyad’s extraordinary adventure to life as Diana sets out to prove that will and determination are all you need to make the unimaginable possible.

2014 Open Water Swimming Almanac

An Almanac for Open Water Swimming

An almanac is essentially a body of knowledge which is so complete that it enables people in different fields to make predictions about the future of their respective industries.

This, for example, was the purpose of the traditional farmers almanacs. It enabled farmers to determine as accurately as possible which crops to plant for the greatest harvests in a given year.

But the farmers almanac was just one example among many.
There are, of course, many different kinds of almanacs.

In fact, there is even one for open water swimming...
