These datasets contain the ice sheet model simulation from the ABUMIP (Antarctic BUttressing Model Intercomparison Project) effort. ABUMIP aims at comparing model responses to complete loss of buttressing by investigating the end-member of ice-shelf buttressing, i.e., the total loss of ice shelves. This enables gauging the sensitivity of different ice sheet models with respect to grounding-line retreat, as a function of basal sliding, isostasy, and other model parameters.

The experiments are kept simple and build on existing InitMIP-Antarctica experiments (Seroussi et al. 2019) within the framework of ISMIP6 (Nowicki et al., 2016, 2020). See here for the protocol, participating models and requested model output data.  Results of ABUMIP have been published in Sun et al. (2020). Key characteristics of participating models are found in the table below (Table 1 of Sun et al. (2020)).

The experimental protocol and datasets for the ISMIP6-ABUMIP standalone ice sheet simulations would not have been possible without the effort of many scientists that have given their time and expertise. ISMIP6 would like to thank the ABUMIP leadership: Frank Pattyn, Nick Golledge and Sainan Sun. Finally, we thank the ISMIP6 ice sheet modelers for their feedback on the design of the protocol and their willingness to participate in ISMIP6.
