The land throughout the United States is dotted with uncountable lakes and ponds, but is there a difference between the two, ...

Satellite data reveals 21% of oceans have darkened, affecting photic zones and marine life. Researchers warn of severe effects on global marine life and ecosystems.

More than one-fifth of the global ocean—an area spanning more than 75 million sq km—has been the subject of ocean darkening over the past two decades, according to new research.

Study site and sampling. Lake Erie was sampled on surveys aboard CCGS GRIFFON during February 2011–2012 and aboard R/V LAKE GUARDIAN during April 2010–2011. Sites in ice-covered western Lake ...

The vast, sunlit waters of the ocean’s surface, known as the photic zone, nurture 90% of marine life. Sunlight and moonlight in this crucial region guide marine creatures and maintain global ...

But the photic zone is shrinking, rendering that figure inaccurate in some parts of the ocean. A new study reveals that 21% of the ocean has gotten darker over the last two decades, ...

Between 2003 and 2022, roughly 30 million square miles of ocean saw photic zones darken. That’s the same size as Europe, Africa, China and North America’s land areas combined.

A world map showing changes in global photic zones between 2003 and 2022. Reds indicate regions where the oceans are getting darker, while blues indicate regions where oceans are getting lighter ...

Between 2003 and 2022, roughly 30 million square miles of ocean saw photic zones darken. That’s the same size as Europe, Africa, China and North America’s land areas combined.

The photic zone extends roughly 200 meters below the ocean's surface, forming the base for countless marine ecosystems. But a recent study published in Global Change Biology shows alarming changes.

Between 2003 and 2022, roughly 30 million square miles of ocean saw photic zones darken. That’s the same size as Europe, Africa, China and North America’s land areas combined.
