MASIE and NSIDC are two different sea ice indexes. The difference between the two methodologies is here.
Right now MASIE is running about 1,000,000 sq km lower than 2012. The Bering Sea region is running over 500,000 sq km lower than 2012.
2012 was the highest MASIE maximum (data only goes back to 2006) and also the lowest minimum in the summer.
