Low flows in the Murray River in recent years have harmed tiny marine plants called phytoplankton, with consequences for local marine species and management.
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.
Young African penguins are following the usual cues to feeding grounds only to find that the sources of food in these places is no longer available. This is devastating for their numbers.
Japan’s fleet is on its way to the Southern Ocean for more “scientific” whaling. But a new resolution pointing out the importance of whale poo could help remove Japan’s rationale for lethal research.
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.
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.
They give us part of the air we breathe but microscopic phytoplankton can also be toxic. They are also on the move thanks to climate change so a new Australian database hopes to monitor any changes.
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.
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…
The Saharan dust that clogged air and dirtied cars recently may seem like a nuisance, but in fact contains some essential nutrients – if, that is, you’re phytoplankton. The dust and sand blown from Africa…
Phytoplankton are the microscopic plant-like cells that float in the sea’s sunlit surface. They underpin the marine food chain and controversy over their stocks means it’s necessary to better understand…
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…
Global warming is having a significant impact on marine life, as many marine organisms are adapted to live only within the average temperature range of their habitats. This applies to larger fish and sea…
A British Columbian fishing community has drawn almost universal condemnation after dumping 100 tonnes of iron rich dust into the ocean to stimulate a plankton bloom, in an effort to restore salmon numbers…
