Scientists have known for some time that large swathes of the earth's oceans harbor extremely low densities of phytoplankton.
Globally just 0.6% of the world's oceans have been protected, compared to almost 13% of our planet's land area.
All of the SETI searching over the past 50 years is equivalent to examining one 8-ounce glass of water from the Earth's oceans -- a lot of human effort, but not a lot of exploration.

She urged for these sites, which represent 0.3% of the world's oceans, to expand over into the 99% of the oceans that are not protected.
The Unep assessment said the concentration of mercury in the top 100m of the world's oceans had doubled over the past century, and estimated that 260 tonnes of the toxic metal had made their way from soil into rivers and lakes.

It is the UN system's authoritative voice on the state and behaviour of the Earth's atmosphere, its interaction with the oceans, the climate it produces and the resulting distribution of water resources.
The exact value of these resources is impossible to calculate reliably, but a leading UN official described the scale of mineral deposits in the world's oceans as "staggering" with "several hundred years' worth of cobalt and nickel".

The most apparent and shocking of which is the plastic waste that can now be found scattered across the surfaces and the depths of our planet's oceans.
Because of the distance that low-frequency sound waves can travel under water, a set of four ships emitting sound at 235 decibels could monitor 80% of the world's oceans for submarines.

The massive over-fishing of the oceans has already led to the near-disappearance of some of the world's fish.
Since oceans cover two-thirds of the Earth's surface, it's more likely debris will hit water than land.
To understand the nutrient composition of the ancient oceans, it's important to know which iron minerals were around at the time.
Scientists are enlisting sailors and fishermen to help with what they hope will be the world's biggest study of plankton in the oceans.

With even the faintest hopes of victory faintly banished, survival was the watchword for India and the two right-handers with oceans of experience behind them kept Australia's bowlers at bay.
The chopper breathalyser is featured in the BBC's new Oceans series, which records a series of underwater scientific expeditions aimed at building up a global picture of the state of our seas.

The world's oceans have already absorbed a third to a half of the CO2 produced by humans, principally by the burning of fossil fuels, over the past 200 years.
Inhabitat recently reported on Boyan Slat, a 19-year-old student who designed an ocean cleanup array that he estimates could remove 7.25 million tons of plastic from the world's oceans.
In the ancient oceans, green rust's ability to pull nickel out of the water would have been critical for some life forms, since nickel is an important nutrient for microbes that produce methane.
Scientists fear that the population of phytoplankton in the world's oceans is being affected by rising sea temperatures, with a paper published in the journal Nature in 2010 controversially suggesting that it had declined by as much as 40% since the 1950s due to climate change.
