Researchers investigated how acidic oceans affect plankton in Prydz Bay, East Antarctica.

Acidic oceans are disrupting a major part of the carbon cycle, slowing how seas absorb carbon from the atmosphere. This could massively speed up the effects of climate change.v

If the Amazon rainforest functions as our planet's lungs, what do raging wildfires threaten? An atmospheric scientist explains why the fires, though devastating, won't suffocate life on Earth.

Plankton in the world's oldest and deepest lake are being disrupted by exceptionally warm waters.
From the largest whales to the smallest plankton and microscopic life, we’re all tightly connected to planet Earth.
Although often separated as two unique subjects in science, geology and biology have been intricately intertwined since life on Earth first evolved billions of years ago.
Sustained ocean warming could greatly reduce catches of fish like these herring photographed off Norway.
Fish are a key food source for millions of people worldwide. But a recent study finds long-term warming over the next 200 years could starve tiny plankton, with impacts that would ripple up food chains.

Plankton has a chemical fingerprint that reveals where it came from. Scientists have now used this to track sharks at the opposite end of the food web.

A recent study shows plankton that have adapted to road salt have disrupted circadian rhythms. This finding suggests that environmental pollutants could also affect human circadian clocks.

The world's oceans are home to innumerable life forms, from sponges to sea lions, and scientists have many creative ways of studying them.
Furious winds keep the McMurdo Dry Valleys in Anarctica free of snow and ice. Calcites found in the valleys have revealed the secrets of ancient subglacial volcanoes.
Melting ice from Antartica could feed vast plankton blooms, trapping carbon in the ocean. To understand this complex mechanism, researchers looked at volcanoes deep under glaciers.
Watch out, there’s a mixotroph about.
They 'engulf living prey, suck out their innards, poison them, harpoon them, make them explode, and steal and reuse body parts'. And we ignore them at our peril.
The Balleny Islands off East Antarctica - one of the many stops along the way.
Why spend three months completing a lap of Antarctica (and probably getting seasick along the way)? It's the only way to get vital clues about the remote Southern Ocean and its influence on the planet.

Most ocean species start out as larvae drifting with currents. Using underwater robots, scientists have found that larvae use swimming motions to affect their course and reach suitable places to grow.

Tiny organisms change ocean acidity to benefit themselves.

The dust storm that turned Sydney red in 2009 triggered plankton blooms in the Tasman Sea, demonstrating how we might fertilise the ocean to take up more carbon dioxide.
The Southern Ocean is remote, cloudy – and full of plankton.
These tiny organisms play a big role in regulating the Earth's climate.
Phytoplankton are responsible for half the world’s productivity. Here, a phytoplankton bloom in the northern Pacific.

You may not have heard of them or given them much thought, but phytoplankton — the microscopic plants that grow throughout the world’s oceans — are the foundation of oceanic food webs. Although tiny, they…
Vomiting since 500-470 BC.
As I was growing up, any time my mother suggested buying mussels or cockles for dinner, my gran would pipe up with the old adage that “you should only be eating shellfish when there’s an ‘R’ in the month…
Hudson Bay Lowlands are staying greener for longer as temperatures rise.
Lakes of the Hudson Bay Lowlands, in northeast Canada, are showing evidence of abrupt change in one of the last Arctic regions of the world to have experienced global warming, according to Canadian research…
In them, lies climate data.
Climate change in the past can tell us much about what is happening today. New research shows how plankton shells dredged from sea floors hold the information we seek. For climate data dating back as far…
