Novel monitoring of Antarctic ice shelf basal melting using a fiber‐optic distributed temperature sensing mooring
Measuring basal melting of ice shelves is challenging and represents a critical component toward understanding ocean‐ice interactions and climate change. In November 2011, moorings containing fiber‐optic cables for distributed temperature sensing (DTS) were installed through the McMurdo Ice Shelf, A...

Measuring basal melting of ice shelves is challenging and represents a critical component toward understanding ocean‐ice interactions and climate change.
