Plastic pollution on a beach on Bali, Indonesia.
Asian countries have become a dumping ground for the plastic waste from wealthy countries.

When you study volcanoes at mid-ocean ridges, doing fieldwork means becoming an aquanaut – diving thousands of feet to the ocean floor in the submersible Alvin, trading tight quarters for amazing views.
Data from hydrophones in the Indian ocean has raised new questions about what happened to MH370.
Hokusai’s great wave, woodcut, c.1829-33.
Recreating freak waves can tell us a lot about the nature of the sea.
Seahorse in aquariums and the wild can be photographed safely.
Contrary to dozens of aquariums' warning signs, flash photography does not affect seahorses.
Teenager Alex Weber and friends collected nearly 40,000 golf balls hit into the ocean from a handful of California golf courses.
Snorkeling off the California coast, a high school student found heaps of golf balls on the ocean floor. With a marine scientist, she showed that golf courses were producing tons of plastic pollution.
When the sea level rises to its highest point, we call that high tide. When it falls to its lowest point, that’s called low tide.
The Moon has gravity of its own, which pulls the oceans (and us) towards it.
Deep sea corals off Florida.
A massive new discovery this summer of miles of corals in deep waters off South Carolina shows how much we have yet to learn about life on the ocean floor.
The Giant Sea Bass at the California Academy of Sciences. Fishes'sense of smell is highly affected by high level of carbon dioxide in the ocean.
Increase of carbon dioxide in the ocean affects the way fish detect predators, mates or food and could threaten not only individual fish but entire populations.
The Antarctic Circumpolar Current keeps Antarctica cold.
The Antarctic Circumpolar Current provides a barrier to heat that keeps warm subtropical waters away from Antarctica. Yet, there are a few places where the heat gets through.
Surgeonfish on a reef in the Maldives.
Drastic oxygen losses in the world's oceans millions of years ago coincided with mass extinctions. Scientists see this as a warning about how climate change could affect oceans today.
Globalised fishing can leave workers vulnerable to exploitation.
A lack of sustainability, profitability and transparency in the global fishing industry is exacerbating the problem of slave-like working conditions for crew. Here are the warning signs to look out for.
The ocean absorbs about 90 percent of the excess heat produced as climate change warms the earth.
According to a new study, the oceans have absorbed more heat from climate change than previously thought. This could mean the Earth will warm even faster in the future than scientists have predicted.
A member of a rare group of 410-million-year-old jawless fishes from Australia meets a mate.

New research shows shallow, near-land seas similar to Bass Strait were critical in the early days of fish evolution. These are the waters we need to protect now to ensure ongoing biodiversity.
An effort to increase such areas can pose a particular threat to island overseas territories.
Building an artificial reef.
Coral reefs are in crisis around the world, and may disappear entirely. 3D printing is a new idea to help them – but it won't be a cure all.
A three-banded clownfish (
Amphiprion ocellaris) navigates the anemones of the Andaman Coral Reef, India.
Our children all know the little clownfish Nemo, star of the Pixar film. But why does he have three stripes, rather than one or two? Developmental and evolutionary biology are revealing the answer.
Swordfish only – no bycatch, please.

A new tool called EcoCast helps fishermen in the West Coast figure out where it's best to fish that day.
The scientific drilling ship JOIDES Resolution arrives in Honolulu after successful sea trials and testing of scientific and drilling equipment.
The ocean floor holds unique information about Earth's history. Scientific ocean drilling, which started 50 years ago, has yielded insights into climate change, geohazards and the key conditions for life.
The warming of the oceans means that the plants and organisms used as warning systems for pollution are being rendered ineffective.
