For a long time, researchers have been debating what it looked like in the cold times of Earth's history around the North Pole: Kilometer-dick ice, or partly open water full of life? Now, researchers want to have found an answer in sediments.
Frozen, but not sealed: Arctic Ocean remained open to life during ice ages, study suggests
For years, scientists have debated whether a giant thick ice shelf once covered the entire Arctic Ocean during the coldest ice ages. Now, a new study published in Science Advances challenges this idea as the research team found no evidence for the presence of a massive ~1km ice shelf. Instead, the Arctic Ocean appears to have been covered by seasonal sea ice—leaving open water and life-sustaining conditions even during the harshest periods of co…
In the past, the Arctic was covered by a seasonal sea ice cap that allowed life even in the coldest periods of the last 750.00 years. The finding will help to understand how this ocean responded to climate change in the past and how it could do so in the future.The entrance The Arctic Ocean remained open to life during the glaciations was first published in Digital Process.
For years, scientists have debated whether a giant thick ice shelf once covered the entire Arctic Ocean at the time of the coldest ice. Now, a new study published in Scientific Advances contests this idea while the research team has found no evidence of the presence of [...]
