Abstract:
This data set represents the model results plotted in the figures in Bett et al. (2020). Data portrays Amundsen Sea freshwater fluxes and freshwater passive tracer results, along with the results on the effect of grounded icebergs and iceberg melt on sea ice and oceanic heat content. These results are derived from Amundsen Sea regional model simulations over the period 1979-2018, with the first 10 years regarded as model spin up. For full descriptions of the results plotted in each figure see Bett et al. (2020).

| Quality: | A centred 2 year running average is applied to the Hovmoller diagram result files leading these files to have N/A values for the first and last years (see Bett et al. (2020) for more details). | |
| Lineage: | Data was produced using revision c62r of the Massachusetts Institute of Technology General Circulation Model (MITgcm; http://mitgcm.org). The Amundsen Sea model setup used to produce these results is described in detail in Bett et al. (2020). A longitudinal resolution of 0.1o is used, producing a latitudinal spacing ranging from ~2.8 km in the southern part of the domain to ~ 5.2 km at the northern end of the domain. In the vertical, a z-level coordinate system of 50 levels is used, ranging from 10 m resolution near the top to 200 m near the bottom (reaching 5600 m here). |
