The sound is opening up again.

Going back a year on the link shows that it was further advanced in 2016. The limit of daytime images is Feb 9th - https://worldview.earthdata.nasa.gov/?p=arctic&l=VIIRS_SNPP_CorrectedReflectance_TrueColor(hidden),MODIS_Aqua_CorrectedReflectance_TrueColor,MODIS_Terra_CorrectedReflectance_TrueColor(hidden),Reference_Labels(hidden),Reference_Features(hidden),Coastlines&t=2016-02-09&z=3&v=346070.42926684907,-2241817.7462289836,1329110.429266849,-1737497.7462289834&ab=off&as=2017-02-27&ae=2017-03-04&av=2&al=true (https://worldview.earthdata.nasa.gov/?p=arctic&l=VIIRS_SNPP_CorrectedReflectance_TrueColor(hidden),MODIS_Aqua_CorrectedReflectance_TrueColor,MODIS_Terra_CorrectedReflectance_TrueColor(hidden),Reference_Labels(hidden),Reference_Features(hidden),Coastlines&t=2016-02-09&z=3&v=346070.42926684907,-2241817.7462289836,1329110.429266849,-1737497.7462289834&ab=off&as=2017-02-27&ae=2017-03-04&av=2&al=true) . Nighttime infrared shows action back into Janurary but there are many images with clouds.

2015 was slightly later - March 4th.

2014 was much further advanced at this stage (as per the first posting)

2013 was about the same as 2017 on March 18. The images appear to be out of registration - see https://worldview.earthdata.nasa.gov/?p=arctic&l=VIIRS_SNPP_CorrectedReflectance_TrueColor(hidden),MODIS_Aqua_CorrectedReflectance_TrueColor(hidden),MODIS_Terra_CorrectedReflectance_TrueColor,Coastlines(hidden)&t=2013-03-18&z=3&v=-1119366.8878650272,-2233228.8104030616,-573502.925571783,-1740318.8778946784&r=-36.0000&ab=off&as=2017-02-27&ae=2017-03-04&av=2&al=true (https://worldview.earthdata.nasa.gov/?p=arctic&l=VIIRS_SNPP_CorrectedReflectance_TrueColor(hidden),MODIS_Aqua_CorrectedReflectance_TrueColor(hidden),MODIS_Terra_CorrectedReflectance_TrueColor,Coastlines(hidden)&t=2013-03-18&z=3&v=-1119366.8878650272,-2233228.8104030616,-573502.925571783,-1740318.8778946784&r=-36.0000&ab=off&as=2017-02-27&ae=2017-03-04&av=2&al=true)

In 2012 the images start on 9th May and show an area melted out, but strong ice holding in the sound - https://worldview.earthdata.nasa.gov/?p=arctic&l=VIIRS_SNPP_CorrectedReflectance_TrueColor,MODIS_Aqua_CorrectedReflectance_TrueColor,MODIS_Terra_CorrectedReflectance_TrueColor,Coastlines(hidden)&t=2012-05-09&z=3&v=-1119366.8878650272,-2233228.8104030616,-573502.925571783,-1740318.8778946784&r=-36.0000&ab=off&as=2017-02-27&ae=2017-03-04&av=2&al=true (https://worldview.earthdata.nasa.gov/?p=arctic&l=VIIRS_SNPP_CorrectedReflectance_TrueColor,MODIS_Aqua_CorrectedReflectance_TrueColor,MODIS_Terra_CorrectedReflectance_TrueColor,Coastlines(hidden)&t=2012-05-09&z=3&v=-1119366.8878650272,-2233228.8104030616,-573502.925571783,-1740318.8778946784&r=-36.0000&ab=off&as=2017-02-27&ae=2017-03-04&av=2&al=true)
