Marine biologists are flying a bespoke mini-submarine under the sea ice to explore environments around Davis research station that have never been seen before.
As shipping traffic increases in the Arctic, fish are racing to get out of the way
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 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.
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.
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.
For the first time, indigenous communities living around the Bering Sea were invited to share their perspectives of the changing Arctic for the 2019 edition of NOAA’s annual Arctic Report Card.
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.
