Where is Arctic sea ice NOW?

To give you the best available Arctic-wide answer to the above question, the MASIE (may-zee) product is produced in cooperation with the U.S. National Ice Center (NIC).
MASIE lets you view and download:

• Northern Hemisphere-wide sea ice coverage since 01 Jan. 2006.
• GeoTIFF and shapfile sea ice coverage by region.
• CSV file of sea ice extent  for the entire Northern Hemisphere and by region.

MASIE uses the most recent full day of data from NIC, obtained nightly. As is the rule with operational centers, gaps in production can occur without warning.
