Massive global greenhouse gas pollution is changing the chemistry of the world's oceans so much that scientists now predict it could severely damage shellfish populations and the nations that depend on the harvests if significant action isn't taken.
Human activity and climate change have left about 75% of the world's coral reefs threatened, putting the livelihoods of many countries that depend on the ocean ecosystems at risk, according to a report released this week.
Four weeks after the catastrophic blowout that killed 11 workers and gushed millions of barrels of toxic crude oil into the Gulf of Mexico last spring, President Obama set up an independent commission to determine what went wrong and what we must do to make sure nothing like this ever happens again.
The chemistry of the world's oceans is changing at a rate not seen for 65 million years, with far-reaching implications for marine biodiversity and food security, according to a new United Nations study released Thursday.
The oceans have become so depleted by over-fishing, pollution and climate change that they can only be saved by a large global network of reserves, according to a growing consensus among marine scientists.
I grew up on the shores of Sydney Harbor and I fondly remember exploring the crystal clear pools, observing the unique and bountiful marine life. Shells and driftwood, cuttlefish bones and dried seaweed littered the sand. That was the only debris from the ocean beyond that I saw.
Twenty years ago when I had the opportunity to dive to 18,000 feet in the Japanese research submersible "Shinkai 6500" in the Sea of Japan. I fantasized about the amazing animals our team might see deep on the ocean floor: rat-tails, deep sea sharks, and octopi.
For polar explorer Ann Daniels, the worst part of this year's expedition to the Arctic won't be enduring bitterly cold temperatures or pulling a 100-kilogram (220-pound) sledge over steep jagged ridges.
It is a problem of massive plastic proportions -- a giant floating debris field, composed mostly of bits and pieces of plastic, in the northwest Pacific Ocean, about a thousand miles off the coast of California.
Today, Monday, June 8, we recognize the first U.N.-sanctioned World Oceans Day. The event comes after years of pressure from conservation groups and thousands of activists who clamored for everyone to know and understand what's happening in our oceans.
Advances in the study of coral in the last few years has led a group of scientists to conclude that corals almost rival humans in their genetic complexity and their relationship to algae is key to their survival.
