Deep Sixed

In the deep sea, low oxygen levels, scarce sunlight, and freezing water limit the rate at which items decompose: Something that might survive a few years on land could exist for decades underwater. - ROVs photograph trash on the ocean floor.

Total jelly domination - “like cockroaches”

"The world’s oceans have been experiencing enormous blooms of jellyfish, apparently caused by overfishing, declining water quality, and rising sea temperatures. Now, scientists are trying to determine if these outbreaks could represent a “new normal” in which jellyfish increasingly supplant fish.. Total jelly domination would be like turning back the clock to the Precambrian world, more than 550 million years ago."

Whales heavy with metal

"I don't see any future for whale species except extinction." A report (pdf) released Thursday by Ocean Alliance noted high levels of cadmium, aluminum, chromium, lead, silver, mercury and titanium in tissue samples taken by dart gun from nearly 1,000 whales over five years. Concentrations of chromium found in some whales was several times higher than the level required to kill healthy cells in a Petri dish. Mercury in some whales was 16 times higher than a typical shark or swordfish, both known for their high mercury levels. Beyond whales, "You could make a fairly tight argument to say that it is the single greatest health threat that has ever faced the human species."

The Rise of Slime

Altered Oceans: A Primeval Tide of Toxins The fireweed began each spring as tufts of hairy growth and spread across the seafloor fast enough to cover a football field in an hour. When fishermen touched it, their skin broke out in searing welts. Their lips blistered and peeled. Their eyes burned and swelled shut. Water that splashed from their nets spread the inflammation to their legs and torsos.

Canada's forgotten weapons of mass destruction.

Canada's forgotten weapons of mass destruction. Shortly after the end of World War II, the Canadian navy began to dispose of its surplus chemical weapons by dumping them off the shore of Atlantic Canada. Large quantities of chemical agents, including mustard gas, were loaded onto barges and scuttled at undisclosed locations. Over 50 years later, some of these military dumpsites have become lost due to poor record keeping. With increasing offshore oil exploration and a commercially successful shellfish industry, there's a possibility that these forgotten chemical agents could return to the coasts of "Canada's Ocean Playground".
