Marine life hitching a ride on ocean-crossing ships poses a threat to Antarctica’s pristine ecosystems, with the potential for invasive species to arrive from almost anywhere across the globe, say the authors of a new study.
Chilean scientists studying organisms in one of the most remote places on Earth are urging regional leaders to step up efforts to tackle climate change.
The massive Thwaites glacier in West Antarctica contains enough ice to raise global sea levels by 65cm if it were to completely collapse. And, worryingly, recent research suggests that its long-term stability is doubtful as the glacier hemorrhages more and more ice.
The Antarctic Circumpolar Current (ACC), the only ocean current that circumnavigates the planet, is speeding up. For the first time, scientists are able to tell that this is happening by taking advantage of a decades-long set of observational records.
The Arctic Ocean has been getting warmer since the beginning of the 20th century—decades earlier than records suggest—due to warmer water flowing into the delicate polar ecosystem from the Atlantic Ocean.
The sources and impact of sea-based marine litter form the focus of a new report by the Group of Experts on the Scientific Aspects of Marine Environmental Protection (GESAMP*), an advisory body to the United Nations.
NOAA has announced it is initiating the process to consider designating the marine portions of Papahānaumokuākea Marine National Monument as a national marine sanctuary.
