Int'l - World's biggest iceberg FOUR TIMES the size of Greater London is steaming towards the open ocean and could pose a risk to shipping vessels

The 2,239-square-mile A68 iceberg is speeding up in its trajectory north towards the open Southern Ocean. The massive berg that's roughly the size of Delaware broke off from the Antarctic Peninsula back in 2017. A68 broke away due to iceberg calving – the breaking away of masses of ice from the edge of a glacier. Scientists are hopeful that the berg breaks apart once it reaches the ocean so it doesn't cause havoc for ships.

Antarctic - Invasive marine species discovered on non–native kelp rafts in the warmest Antarctic island

Antarctic shallow coastal marine communities were long thought to be isolated from their nearest neighbours by hundreds of kilometres of deep ocean and the Antarctic Circumpolar Current. The discovery of non–native kelp washed up on Antarctic beaches led us to question the permeability of these barriers to species dispersal.

Scientists find far higher than expected rate of underwater glacial melting - Robotic kayaks were used to track meltwater.

Tidewater glaciers, the massive rivers of ice that end in the ocean, may be melting underwater much faster than previously thought, according to a new study that used robotic kayaks. The findings, which challenge current frameworks for analyzing ocean-glacier interactions, have implications for the rest of the world's tidewater glaciers, whose rapid retreat is contributing to sea-level rise.

Deep Antarctic drilling will reveal climate secrets trapped in 1.5 million-year-old ice

An ambitious mission to drill into the Antarctic ice sheet to extract some of the oldest ice on the planet will provide vital clues about a mysterious shift in the behaviour of our planet's climate.

Alien Species Invasions in Antarctica Predicted

A new study identifies the non-native species most likely to invade the Antarctic Peninsula region over the next decade. It provides a baseline for all operators in the region to look at mitigation measures. The study is published in the journal Global Change Biology today, January 13, 2020.
