"Scientists say Earth’s oceans are slowly getting darker, according to new
findings that reveal a concerning trend affecting the largest bodies of water
that cover our planet.
According to the new findings, nearly one-fifth of the global ocean has
darkened within the past two decades. This phenomenon is being driven by
changes in the optical properties of ocean water, which spans more than 75
million square miles of the Earth’s surface.
This progressive darkening results in less light reaching beneath the waves
into areas known as photic zones, where nearly 90% of all ocean life currently
resides. The new findings have aroused concern among scientists over how ocean
darkening may affect organisms that normally rely on light from the sun and
moon.
The research, carried out by scientists from the University of Plymouth and
Plymouth Marine Laboratory, comprises more than a decade of studies on the
impact of light on Earth’s oceans.
The new research, published in
Global Change Biology, combines satellite data
and advanced numerical models to study changes in the depth of photic zones
around the world. It revealed that large portions of open ocean and shallower
coastal waters—an estimated 21% of all global ocean water—had darkened between
2003 and 2022."
