Version of Record online: 7 FEB 2014 | DOI: 10.1002/2013JF002958

Key Points

  • Whillans ice Stream deceleration is variable including a recent doubling
  • Deceleration is attributable to a 10 to 40 Pa/yr increase in basal drag
  • Subglacial hydrology and thermodynamic feedbacks can explain deceleration
