Atmospheric flask O2/N2 and CO2 datasets – Scripps Institution of Oceanography data from Alert, Canada (1989-present), Barrow Alaska (2010-present) and Cold Bay, Alaska (1995-present)
This dataset consists of time-series measurements of oxygen-to-nitrogen (O2/N2) ratio and carbon dioxide (CO2) from flasks collected at (1) Utqiaġvik (Barrow), Alaska (2) Alert, Nunavut, on the north-eastern tip of Ellesmere Island, and (3) Cold Bay Alaska. The flasks are collected by staff from the...
