A Philippine Coral Reef Survives
One of the greatest coral reef ecosystems in the world, the Tubbataha Reef in the Philippines, continues to prosper. Undersea coral walls that plunge more than 300 feet deep are home to some 600 species of fish and 360 kinds of coral, about half of all known species. According to experts, the ocean wilderness of Tubbataha Reef is about the closest thing to a true natural state for any reef in the world.
Floating Cities
A familiar theme in science fiction is the idea of floating cities – independent, self-sustaining nation-states at sea where start-up societies work to redesign society and government and don’t have to fight over who owns the land. The concept even has a name: seasteading.
Is Sustainable Seafood Really Sustainable?
Tuna is perhaps the most popular seafood. We eat it out of a can, we splurge on high-end sushi, and we prepare it in many other ways. Some species of tuna are over-fished and some fishing methods are unsustainable. As concerned consumers, we would like to know what sort of tuna we are eating.

Can We Stop A Hurricane?
This has been a particularly terrible hurricane season. Harvey, Irma, Jose, Maria, and Nate all formed in the Atlantic and headed for North America. People in Houston, Florida, all over the Caribbean, and especially Puerto Rico are trying to recover from the effects of these powerful storms.
Corals Like Plastic
Microplastics, which are tiny pieces of weathered plastic less than 5 millimeters in diameter, have been accumulating in the oceans for the past 40 years and are now ubiquitous in the marine environment. They are a major threat to many kinds of marine life, including numerous species of birds, turtles, fish, marine mammals and invertebrates who ingest the stuff causing a variety of problems.
Tsunami And Invasive Species
According to a new study published in the journal Science, scientists have discovered that hundreds of Japanese marine species have been swept across the Pacific Ocean to the United States following the deadly Tsunami in 2011.
Looking For “Super Coral”
Coral reefs are essential for much of marine life and are the basis of many commercial fisheries. In places from Florida to Australia, they are major tourist attractions. Estimates are that the economic impact of coral reefs is more than $375 billion a year. And apart from all of that, they are some of the most beautiful places on the planet.
More Power From The Sea
The Okinawa Institute of Science and Technology or OIST has been working on ways to generate electricity from the ocean for five years. Their initial project, known as “Sea Horse” uses submerged turbines anchored to the sea floor that convert the kinetic energy of sustained natural currents into useful electricity, which is then delivered by cables to the land. The project has been successful and OIST is now planning the next phase.
A Ton Of Plastic Per Person
A study by the American Association for the Advancement of Science has produced an estimate of the total amount of plastic manufactured worldwide since the 1950s. The researchers then measured that data against statistics on recycling, incineration and discard rates. The results are sobering.
Mass Production Of Biodegradable Plastic
Plastic pollution is a major problem for the world’s oceans and non-biodegradable plastics continue to fill the planet’s landfills and litter the landscape. There are many approaches to making plant-derived, biodegradable plastics but most of these materials do not offer the resistance to heat and moisture that is characteristic of petroleum-based plastics.
Another Unconventional Fossil Fuel Source
It has only been about 10 years that fracking has been a big deal in the energy world. With it, a largely inaccessible source of fossil fuel became relatively easy pickings. And both the economic benefits and the attendant environmental problems have been grabbing headlines ever since.
