A team of researchers investigate why the ocean has been absorbing more carbon from the atmosphere in recent decades, and find ocean circulation could be responsible.
A team of researchers went back to the same part of Antarctic after a decade to see how the deep ocean had changed, and were surprised to find the deep ocean was fresher than they expected.
The Antarctic Circumpolar current, which wraps around Antarctica and connects the Atlantic, Indian and Pacific Oceans, is notoriously difficult to measure. Recently a group of researchers tackled the wild current, and found it was 30% stronger than scientists previously thought.
In the sea ice battle between the North Pole and the South Pole, there is no winner in 2016, as sea ice cover is plummeting at both poles.
An Australian research team predict future sea-ice habitats for Antarctic krill larvae, and are surprised to find more suitable ice habitats in the future, despite shrinking sea-ice cover.
New analysis of 100 years of sea level measurements from tide gauges show that we might be underestimating the global rate of sea level rise.
The Southern Ocean has been getting less salty for decades, and scientists have finally proved that sea-ice is responsible for the extra fresh water in the ocean.
Scientists confirm an surprising explanation for Antarctica’s expanding sea ice in the tropical Pacific Ocean.
Scientists investigate warm water that drives melting in Antarctica with the help of some seals with high-tech hats.
A group of scientists have delved deeper to solve the puzzle of why the ocean around Antarctica has been cooling, while the rest of the ocean is rapidly warming.
A pair of scientists have figured out how to track deep ocean currents using gravity measurements from space.

Antarctic coasts Despite the dark winters and freezing cold conditions, the coastline of Antarctica is a hotspot for growth of phytoplankton, the tiny, photosynthesizing organisms that […]
Using underwater gliders, researchers explain what caused the extremely warm ocean along the coast of California in 2014-2015 and what this might mean for local ecosystems.

Nature Climate Change The shrinking Antarctic As our planet warms, the melting of glaciers and polar ice caps is causing sea level rise, threatening the future of coastal cities and low lying areas around the world. This melting includes Antarctica’s ice shelves, which add […]
Things heat up as scientists investigate deeper to find out how much heat the ocean can take.
Hear about my adventures living on an icebreaker on the Southern Ocean, deploying ocean robots to understand the chemistry and biology of the Southern Ocean.
Rapid acidification of the Southern Ocean could occur in the next 30 years with potentially huge impacts to local ecosystems.
Scientists use ocean color from satellites to show that tiny ocean plankton may be responsible for making clouds brighter around Antarctica.
