Transient marine ice sheet response to temporally varying forcing

The data set was produced for the work detailed in ''The response of ice sheets to climate variability'' by K Snow et al (2017, Geophys Research Letters). A coupled ice sheet-ocean model is configured in an idealised setting with an inland-deepening bedrock, forced by far-field hydrographic profiles representative of the Amundsen Sea continental shelf. Similar to observed variability, the thermocline depth in the far-field is moved up and down on various times scales as detailed in the publication, with periods ranging from 2 to ~50 years. Bedrock elevation is provided, and annual melt rate and ice thickness (or sub-annual for short time scales) is provided as well for each forcing period. In addition, similar experiments were carried out with an ice-only model with parameterised forcing. These outputs are provided too.

Pass: No

Statement: No "cleaning" was involved. The accuracy is subject to the ability of the model to approximate the differential equations solved, and the ability of the differential equations solved to represent reality, both of which issues have been discussed extensively in the literature (e.g. Durran et al (1999), Numerical Methods for Fluid Dynamics:with Applications in Geophysics, Springer).
