In this video from Reuters, Maurizio Porfiri, an Assistant Professor of Engineering at the Polytechnic Institute of NYU, is working on a robotic fish designed to lead schools of real fish away from dangers, such as oil spills or turbines.

The hardest part for Porfiri and his team has been discovering exactly what traits fish look for in a leader, so that their robot can successfully mimic these to gain the followers. Experimenting with small schools of fish, Porfiri has been fine tuning his robot to swim with the fast and erratic behaviors that fish would perceive a leader, or mate, to have.

Eventually, Porfiri would like to program his robotic fish to autonomously lead schools without any human control necessary, and to one day also be equipped with sophisticated sensors that can collect data on fish and their interactions with their environment and other species.

In this clip from CNN, underwater photographer Gavin Newman heads out to sea with Greenpeace aboard their vessel, Esperanza.

Known for his cave and cave diving photography, on this adventure Newman takes to the Arctic, exploring the mysterious sea bed--now accessible below melting ice--with robotic underwater cameras that he has built. Newman discusses the wonder and excitement of exploring this new frontier, "Nobody has any idea what's below us."

Expecting sights little more exciting than sand and mud, everyone was shocked to find a stunningly colorful ecosystem of living creatures on the Arctic seabed. Newman describes it as "one of the most colorful places I've dived," going on to say, "It really is very unexpected."

Newman also talks about the horrors of bottom trawling, a destructive fishing method now making its way to this untouched location due to the melting ice. "It's like somebody's just plowed a field," Newman says, describing the areas where rich coral systems and seabed life are ripped entirely off the ocean floor.

Scientists recently spent six weeks in the Atlantic and have now returned with more than 10 samples of possible new species.

One group of creatures found on their deep sea exploration could be a missing piece in the evolutionary puzzle between invertebrates and back-boned animals.

Check out this clip from CBS, which has incredible images of these exciting, new discoveries.

While we may like to think that the world's most beautiful beaches are always the cleanest, this is simply untrue. In reality, many of the world's cleanest beaches are located in the most unlikely of places. From New Zealand to Croatia, Iceland to South Africa and Spain, check out HuffPost Green's slideshow of the world's cleanest beaches.

In the aftermath of the gulf oil spill, we at HuffPost Green wanted to scope out some of the world's cleanest beaches for a refreshing outlook. Don't forget to vote on your favorite!


Evaluate your local beach:
Check the water quality at your favorite beach from the NRDC's "Testing the Waters" program in your state. There are 3,500 beaches in the United States and the Clean Beaches Council estimates that Americans take over 2 billion trips to the beach each year.

For international ratings of beaches, the Blue Flag program, composed of a committee of specialists from the United Nations World Tourism Organization and the European Union for Coastal Conservation, checks the water quality and lack of hazardous waste of sites from around the world. Currently, 3,450 beaches have been awarded blue flags.

The Environmental Protection Agency offers tips on how to preserve the nation's beaches.

While the BP oil spill has been labeled the worst environmental catastrophe in recent U.S. history, a biofuel is contributing to a Gulf of Mexico "dead zone" the size of New Jersey that scientists say could be every bit as harmful to the gulf.

In this video from Reuters, Iceland's 100 day whaling season has begun amidst international condemnation and the outcry of environmental conservationists. The controversial practice is considered a birthright by the only two nations that openly pursue it, Iceland and Norway, but is regarded by critics as one of the primary contributions to declining whale numbers, which have only recently begun to recover due to the international whaling moratorium instituted 24 years ago. Japan also practices whaling, but only for what it deems to be "scientific research", often an exploited loophole.

The commencement of Iceland's whaling season comes immediately after nations failed to reach an agreement set forth by the International Whaling Commission to continue the moratorium but permit limited amounts of whales to be hunted by the three countries that continue to do so despite the ban.

Much of the global ocean remains uncharted in terms of pollution, but unfortunately the more we look, the more we find. And now even the most remote, pristine waters on the planet -- the coastal seas of Antarctica -- are being invaded by plastic debris.
