Greenland Ice Sheet Discharge Explorer

Data

This widget visualises the 'living dataset' of Greenland's ice discharge data made available by GEUS.

The dataset updates monthly with new discharge data, which is pulled through to this widget automatically.

How to Use

There are three options for the 'Dataset' drop-down menu:

• Greenland Ice Sheet: Visualise total discharge, in Gt/yr, for the entire ice sheet.
• Regions: Visualise total discharge for seven regions of the ice sheet (Central East, Central West, North East, North, North West, South East, South West) according to Mouginot and Rignot, (2019).
• Sectors (Glaciers): Visualise total discharge for 260 basins (i.e. outlet glaciers), following the Mouginot and Rignot (2019) classification.

The 'Show Error Bounds' box toggles error bars on and off. 'Download CSV' will download the datasets shown on-screen, including discharge (in Gt/yr), error (in Gt/yr), and coverage (in the range 0-1) columns for every selected dataset.
