Ice sheet melting: it’s not just about sea level rise

You've probably heard that climate change is melting the polar ice caps - but what does this actually mean? It refers to the Greenland and Antarctic Ice Sheets, which are large systems of interconnected glaciers, kilometres thick. They are formed by snow falling on land,... click to read more

Warm waters hide in the unlikeliest of places – under the Arctic sea ice

The Polar Regions are a central control and indicator of the Earth's climate. Ice and snow at the poles reflect solar radiation back into space, which helps to keep the Earth cool. However, in recent decades, air temperatures in the Arctic have been rising at... click to read more

Seal poo unravels the microplastic journey through marine food webs

Plastic pollution is now one of the most widespread and significant threats facing our oceans. Microplastics (pieces less than 5 mm in size), in particular, have been in the spotlight for a number of reasons. Firstly, there's so many of them! Microplastics come from a... click to read more

The shape of the ocean: deep waters and their movement

Oceanographers know how the deepest reaches of the ocean are filled: by very cold and dense waters formed in contact with the polar air and ice of Antarctica. These dense Antarctic waters plunge under their own weight and snake along the global seafloor at depths... click to read more
