Today is World Ocean Day, something I fully support* [Ocean Conservancy]. "If you are lucky enough to be an orarian (coastal dweller) I hope you appreciate your circumstances; if you are lucky or rich enough to ever get into outer-space and you look down at The Earth, most of what you see will be the blue of water: over 70% of the planet's surface is covered by ocean and it is because of this that the Earth is sometimes called "the water planet" - less than three-tenths (maths was always a strong point) of our globe is covered with land." just looked at that from my Our Ocean obligation...post in 2006. Hope it's still true ;-)
Another interesting stat: How much water is there on the planet? Less than 3% of that is freshwater. Of that, nearly 70% is in ice caps, glaciers, and permanent snow, and 30% sits in ground water.
* unlike many other 'name Days' and despite the fact that the climate change hysteria has affected ALL such institutions and charities. Also World Water Day, World Toilet Day and World Water Monitoring Day are up there and worth a mention.
Of course the Oceans aren't just water: there is the very bad, and the good: Obambulating
"95% to 98% of the biomass in the ocean is in microbes, which produce about half of the oxygen on the planet."There are more than 1030 viruses on Earth and the oceans are...er, An Ocean of Viruses. "The sheer number of viruses and their intimate relationship with microbial life suggest that viruses play a critical role in the planet’s biosphere."
"Ocean viruses may turn over as much as 150 gigatons of carbon per year... "
Good info from NASA: "The story of oceans is the story of life. Oceans define our home planet, covering the majority of Earth’s surface and driving the water cycle that dominates our land and atmosphere. But more profound still, the story of our oceans envelops our home in a far larger context that reaches deep into the universe and places us in a rich family of ocean worlds that span our solar system and beyond." (well, it is NASA!)
