Coastal exposure index of sea ice in Antarctica
This is a simple index which looks at the 360x1-degree longitudinal wedges around the Antarctic continent to see if there is any sea ice (where sea ice concentration is greater than 15%) to the north of the continent in each of these wedges.
The index goes from 0 (sea ice to the north off the continent in every longitude wedge) to 360 (no sea ice around the continent at all.
Notes about the spreadsheet:
"-" means no data. Satellite data was not available for those years.
Otherwise the index goes from 0 through to 360.
- Zero means that there is no longitude around the continent where there is coastal exposure.
- 18 (for example) means that there are 18 longitudinal wedges around the continent with coastal exposure.
This project used the following NASA data to develop the coastal exposure index:
