Hidden Beneath the Ocean’s Surface, Nearly 16 Million Tons of Microplastic

Our plastic bags seem to end up floating like waterlogged jellyfish in the sea.

Discarded bottles spoil pristine beaches around the world.

Now, scientists have a glimpse of what happens when tiny fragments of plastic break off and end up on the ocean floor.

In what researchers called the first such global estimate, Australia’s national science agency says that 9.25 million to 15.87 million tons of microplastics — fragments measuring between five millimeters and one micrometer — are embedded on the sea floor.

That is far more than on the ocean’s surface.

It is the equivalent of 18 to 24 shopping bags full of small plastic fragments for every foot of coastline on every continent except for Antarctica.

It is an issue that activists have long warned about even as the fight to clean up the ocean has focused largely on the eradication of single-use plastic products like shopping bags.

Study Shows O. Megalodon Was The Largest Shark To Ever Swim In Our Planet’s Oceans

According to a new study, the megatooth shark Otodus megalodon was the largest shark to ever swim in our planet’s oceans. O. megalodon is an extinct species of shark that lived approximately 23 to 3.6 million years ago. The exact cause of its extinction is still debated, likely a combination of environmental change and competition with smaller shark species played a role.

Despite its fame in pop-culture, surprisingly little is known about the life-appearance of the megalodon. Sharks have a cartilaginous skeleton that will quickly decay after death. Only their hard teeth survive the fossilization process. A recent study published in the journal Scientific Reports discussing the body size of O. megalodon, concluded

The Oceans Are Stratifying Into a Layer Cake

The oceans are facing a host of maladies, from acidification to sea level rise. Turning them into a ginormous liquid layer cake may sound comparatively benign (and delicious). But while Earther is decidedly pro-cake, this is in fact a bad situation.

New research published in Nature Climate Change on Monday shows that oceans are stratifying faster than previous research indicated. It’s due largely to rising temperatures, and the layer cake-ification of the oceans imperils carbon storage and could upend ecology around the world.

By now, it’s blindingly obvious that the planet is trapping more heat, thanks to a blanket of human-driven greenhouse gas emissions. But the ocean stratification impact is not one of the easily seen consequences, unlike *gestures wildly at the world right now.* To get a grasp on how climate change is splitting

Satellite Science Is Helping The Environment, From Farms To Oceans

The same technology used for satellites can monitor both lands and seafloors, helping adaptation and mitigation practices against climate change.

Vultus and PlanBlue are two of the nine climate ventures selected by the European Institute of Innovation and Technology (EIT) Climate KIC to receive €4 million, as part of the EIT Crisis Response Initiative, with the aim to help start-ups recover from the impacts of the COVID-19 crisis. To choose who deserved the grant, EIT Climate-KIC took into consideration the potential reduction of greenhouse gases emissions made possible by each innovation.

“Our entrepreneurship community has been severely affected by the COVID-19 crisis, be it through  last-minute investment cancellations, losing customers, global supply chains being interrupted or  even just distraction
