Simulated changes in East Antarctic mass balance and grounded area in response to a shift to circumpolar deep water forced melting from the present-day oceanic regime
The dataset contains processed model output of future simulations of the East Antarctic Ice Sheet using the Ua ice dynamics model (https://github.com/GHilmarG/UaSource). Simulations were run for 200 years comparing the impact of both an intermediate (RCP4.5 emissions scenario) and extreme (RCP8.5 emissions scenario) as well as maintaining the current oceanic regime or switching to one dominated by circumpolar deep water intrusions. A reference run with constant present-day forcing is also included to assess the relative impacts of the various forcing scenarios.

- Statement
- To account for model bias a baseline run with constant forcing was performed. To account for errors in the ocean and atmospheric forcing applied two further runs were performed for each emission scenario, a "positive bias" mass balance (high precipitation, low ocean melting) and "negative bias" mass balance (low precipitation, high ocean melting) to capture the envelope of expected results.
