The SeaRISE experiments seek to quantify the sensitivity of ice sheets to external environmental forcings. At the initial stage of the effort, three broad model type were considered. Experiments, along with descriptions of set-up, initialization, and control run can be found in these links: Category 1: Whole Ice Sheet, Category 2: Ice-Stream/Ice-Shelf,Category 3: Ice-Shelf/Ocean.

As the project evolved, category 2 and 3 were put aside, and the effort focussed on experiments for whole ice sheet models. These experiments were agreed by the SeaRISE community as representing the most effective approach to meeting the SeaRISE goal of informing the IPCC AR5 report. The sensitivity experiment are summarized in the figure below, and are organized as sets of experiments that perturb the ice sheet at a single boundary (upper surface, lower surface, or ocean perimeter), combination of single forcing experiments, and the R8 experiment. The later was designed to approximate the RCP8.5 scenario considered by the IPCC. The experimental set up for these SeaRISE experiments is described in Category 1: Whole Ice Sheet, and also explained in Bindschadler et al. (2013). These SeaRISE experiments were also carried out by a flowband model (see Parizek et al., 2013).
