In the chart below MASIE shows 2016 Mid-July Arctic ice extent has slipped below average and 2015. SII is back on line and was reporting similar extents during June (as it has in the past). But in July SII is showing ~400k km2 less ice most days. (SII and MASIE comparison is here.)
Looking into the details, some marginal seas are melting earlier than last year, while the central, enduring ice pack is relatively unaffected. Despite greater losses in Okhotsk, 2016 ice extent in June is fairly ordinary with slight differences across the regions.
