The Benefits of Better Ocean Weather Forecasting
Improvements in our ability to forecast oceanic conditions weeks to months in advance will help communities, industries, and other groups prepare amid a changing climate.
Could AI Be Useful for Arctic Communities Facing Sea Ice Loss?
The forecasting tool IceNet promises to be a useful tool for evaluating sea ice loss in the Arctic. But ethical and logistic considerations have to be taken before scientific and Indigenous communities start working together.
Melting Arctic Sea Ice Strengthens Tides
If climate change throws off the seasonal freeze-thaw cycle of Arctic sea ice, it could trigger a reinforcing cycle of sea ice melt in parts of the Canadian Arctic.
西伯利亚科雷马河的多年冻土碳元素含量极小
新的研究发现,北极河流目前运输的多年冻土来源的溶解有机碳有限,这对理解该地区变化的碳循环及其加速气候变化的潜力具有启示意义。
New Insights into Polar Stratospheric Clouds
New satellite observations of polar stratospheric clouds have advanced our understanding of how, when, and where they form, their composition, and their role in ozone depletion.
When Wild Weather Blew Old Sea Ice South
Last winter, an unprecedented high-pressure system over the Arctic drove nearly a quarter of old sea ice into warmer waters, putting it at greater risk of melting.
Ice Lenses May Cause Many Arctic Landslides
When permafrost thaw reaches concentrations of ice underneath the surface, it may trigger local soil instability.
An Iceberg May Have Initiated a Submarine Landslide
A new study shows that icebergs may initiate submarine landslides when they collide with the seafloor.
Studying Arctic Fjords with Crowdsourced Science and Sailboats
A new study demonstrates the benefits of crowdsourcing science using sailboats to better understand the impact of melting sea ice in the Arctic.
