Amundsen-Ross sea ice reconstruction based on data from the Ferrigno ice core (F10), Bryan Coast, West Antarctica
GB/NERC/BAS/PDC/00941

Summary

Abstract:
This dataset provides a 308 year record of methansulphonic acid (MSA) from coastal West Antarctica, representing sea ice conditions in the Amundsen-Ross Sea. Annual average MSA has been calculated from the 136 m Ferrigno ice core (F10), drilled on the Bryan Coast in Ellsworth Land, West Antarctica during the austral summer 2010/11. The sea ice extent is based on geometric mean regression of MSA flux with satellite sea ice extent from 146 degrees west. The record was measured using a Dionex ICS2500 anion system at 5 cm resolution, corresponding to approximately 14 samples a year.

Funding was provided by the NERC grant NE/J020710/1.
