yedoma
Yedoma refers to a specific type of permafrost found in Siberia and Alaska. It is characterized by its ice-rich nature, often containing high concentrations of ground ice, and its fine-grained sediment composition, typically silt and clay. This permafrost is ancient, with radiocarbon dating suggesting that many yedoma deposits formed during the Pleistocene epoch, some dating back over 50,000 years.
The organic content within yedoma is often significant, with preserved plant and animal remains contributing to
Scientific research into yedoma is crucial for understanding past climate conditions and predicting future environmental changes.
