The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Shallow shelf approximation as a “sliding law” in a thermomechanically coupled ice sheet model (2008, methodology): “The underlying physical model is supported by recent observations [Joughin et al., 2004b; Tulaczyk et al., 2000] and theory [Schoof , 2006a] for ice streams.”
Basal mechanics of ice streams: Insights from the stick‐slip motion of Whillans Ice Stream, West Antarctica (2009, background): “…the mass balance of water near the bed of the ice stream [e.g, Tulaczyk et al., 2000b], our results show that the bed of an ice stream is capable of relatively large variations, >0.35 kPa, relative to the strength of the bed, likely 5 kPa [Joughin et al., 2004a], during the course of a single day.”
A variational approach to ice stream flow (2006, background): “For a present day ice sheet, this question does not arise as we can observe where streaming flow is taking place (as is done for instance in Joughin et al. 2004).”
