Phytoplankton under a microscope.
Phytoplankton are tiny, but they do important work.
The sea is blue because of the way water absorbs light, the way particles in the water scatter light, and also because some of the blue light from the sky is reflected.
Photons stream from the sun and interact with all matter on Earth. Depending on what the light touches, some of the photons will get absorbed or soaked up. And some will bounce back.
Project Oceanology class retrieves a bottom trawl at the mouth of the Thames River.
For decades, New England students took field trips out into the Long Island Sound. Their data show how quickly the sound is warming, leading to fewer American lobster, rock crab and winter flounder.
Marine parks are good for fish - especially if they’re in the right areas.
With strategic planning, the marine protected area network could be a third smaller, cost half as much, and still meet the international target of protecting 10% of every ecosystem.
Watch out, currents about.
It's good to know how currents are formed in the ocean, as they can be quite dangerous!
Trapping carbon dioxide in minerals happens naturally over thousands of years. Can humans speed it up – safely?
Adding industrial chemicals and natural alkaline minerals could slow climate change, but like other geoengineering proposals, it comes with many complex technical and legal challenges.
Angler fish haunt the deep seas.
The pressure in the deepest part of the ocean can be 1,000 times greater than the pressure we experience at sea level – but creatures that live and visit there have some very special features.
When temperatures rise and ice melts, more water flows to the seas and ocean water warms and expands in volume.
Plastic is not as much of a threat to oceans as climate change or over-fishing.
Nurdles are a raw feedstock used to make most of the plastic products we use everyday, but they're flooding the ocean as "mermaid tears".
Zambezi river delta, snapped by Landsat 8 in March 2018.
Satellites hundreds of miles overheard are helping scientists to predict drought, track floods and see how climate change is changing access to water resources.
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.
