Snow depth and ground frost depth at a boreal fen (Oulanka National Park, NE Finland) 1980-2023
Snow and ground frost depths were measured at a boreal fen close to Oulanka research station, northeastern Finland (66°22'N, 29°19'E) in years 1980 to 2023, as part of ongoing long-term surveys conducted by the research station staff. Data were collected manually by reading snow depths on...
