Organic compounds in a sub-Antarctic ice core: A potential suite of sea-ice markers
Investigation of organic compounds in ice cores can potentially unlock a wealth of new information in these climate archives. We present results from the first ever ice core drilled on sub‐Antarctic island Bouvet, representing a climatologically important but understudied region. We analyse a suite...
