Oceans absorb more carbon with weaker ocean circulation

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.

Antarctica’s bottom waters freshen up

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.

Earth’s strongest current even stronger than previously thought

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.

Pole wars: Episode 1 – The Phantom Sea Ice

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.

Positive real estate outlook for Antarctic krill

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.

Tide records could have underestimated global sea level rise

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.

Why the Southern Ocean is getting less salty

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.

Ocean circulation keeping it cool in Antarctica

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.

Ocean robots record California’s latest hot year

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.

Antarctic ice dams at risk

Source: Fürst et al. (2016), The Safety band of Antarctic ice shelves. 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 […]
