Ice Shelf Melt Observations

The NECKLACE Initiative: NEtwork for the Collection of Knowledge on meLt of Antarctic iCe shElves

NECKLACE is a SOOS-endorsed, international initiative led by the British Antarctic Survey to coordinate the collection of ice-shelf melt observations from around Antarctica using newly developed cheap, easily deployed Auto-phase-sensitive Radio Echo Sounding instruments. The time series of melt rates from point locations will complement the satellite-derived maps of spatially-smoothed time-averaged melt rates that are now becoming available, and will be a valuable source of data for assimilation into, or validation of, models of the interaction between the Southern Ocean and the Antarctic Ice Sheet.

SOOS is currently working with the NECKLACE community to provide NECKLACE data. Please contact the SOOS data officer for information on data availability. For information on the instrument or how to contribute to this initiative, please contact NECKLACE leader Keith Nicholls. If you have an ApRES location to add to this map, please contact the SOOS data officer.
