The Law Dome MSA sea ice proxy record: analysis of modern satellite data and re-examination of archival satellite imagery
Understanding the long term trends in sea ice coverage is important, particularly in thecontext of recent reports of increases in Antarctic sea ice extent. Prior to the satellite era, icecore records have been used as a proxy for past sea ice extent in Antarctica, allowinginvestigations of the natur...
