Diamonds To Be An Open Water Swimmer's Best Friend

Science Magazine reported that artificial diamonds with elements of nickel can be used as a temperature probe with unparalleled precision over time and space.

Imagine the possibilities in the open water world - even if the utilization of these diamonds are at least a few (or several) generations off in the future.

It would be totally cool to precisely know - and be able to objectively and automatically record on a universal scale - the water temperature when swimming in the open water.

Tiny diamond probes can measure temperatures ranging from 120°K to 900°K (–153°C to 627°C) — far beyond any scale that open water swimmers need. The probes can also detect temperature changes across distances as small as 5 μm (or 5 thousandths of a millimetre, 0.005 mm) and on timescales as short as 800 picoseconds (0.0000000008 seconds).

The finding describes the artificial diamonds with nickel as being extremely sensitive to temperature fluctuations. They emit a luminescent glow when struck by a pulse of laser light that can be used to calculate temperature. Simply put, as the temperature drops, the diamond glows for longer periods of time.

Co-researcher and spectroscopist Christophe Dujardin of the University of Lyon explains, “There are many kinds of impurities in diamond, and this particular defect was the most interesting. It’s more universal.”

If you are going to do some ice swimming, it will be very good to be precise about the water (and air) temperature. With these diamonds, all the data can be objectively obtained and documented.

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...

The trends are very clear.
The tide is rising for open water swimming.
