Ocean water is saturated with salt, and undrinkable. Most of the freshwater is locked away in glaciers or deep underground. Less than one percent of it is available to us. So why can’t we just take all that seawater, filter out the salt, and have a nearly unlimited supply of clean, drinkable water?
For more than a year, the team trying to reach the deepest point in every ocean faced challenges as timeless as bad weather and as novel as the equipment they invented. This is the story of the explorers who set one of the last meaningful records on earth.
Thwaites Glacier has long been the subject of dark speculation. If this mysterious glacier were to break down into icebergs and eventually collapse into the ocean—it might be more than a scientific curiosity. It might be the kind of event that changes the course of civilization.
By 2050 there could be more plastic in the ocean by weight, than fish. Plastic pollution is definitely one of the largest threats our oceans face today. Meet the engineers who are using rubbish-guzzling boats to stem the flow at its source.
Octopus-hunting freedivers, mounds of shark fins, and a close encounter with a leopard seal are among the judges’ selections for Oceanographic Magazine’s ocean photography awards.
Offshore oil rigs are inherently a higher-cost, higher-risk method of oil extraction, but the oceans are, of course, home to a huge proportion of the world’s oil reserves so, if there are no more low-cost oilfields on land, that’s where the companies go.
Ninety percent of the large fish that were here in the 1950s are now gone. One metric ton of plastic enters the ocean every four seconds. But the biggest problem, thanks largely to our insatiable appetite for fossil fuels, is that the ocean is heating up fast.
Science fiction obsessed Victor Vescovo wanted to be the first person to reach the deepest points of all five oceans – but first he had to build a submarine that was up to it.
The MV Alta drifted without a soul on board in the Atlantic ocean for 18 months, before crashing into the coast of Ireland. Tracking and current data give us intriguing clues about its final, fateful voyage.
Only three people have ever reached the bottom of the deepest part of the ocean. The deep is a world without sunlight, of freezing temperatures, and immense pressure. It’s remained largely unexplored until now. Cutting-edge technology is enabling a new generation of aquanauts to go deeper than ever before.
Every third week, a British Royal Mail ship begins its journey from Cape Town to Saint Helena, the remote island in the Atlantic where Napoleon was once in exile. Five days, with a northwesterly course, and only then do the sheer black cliffs appear in front of RMS St. Helena.
