    An Analysis of the sea ice concentration (SIC) in research blocks 2,3,4, and 5 of subarea 48.6, with sea surface temperature(SST) and statistical models is presented. 

    For research block 4, the SIC in 2019 was the highest for the last 4 years (2016-2019). For research block 5, the SIC in 2019 was also as high as in 2016 but around the west of block 5 the SIC in 2019 was much lower than in 2016. The lower SST anomalies corresponds to the higher SICs in 2019 both in research blocks 4 and 5 and vice versa. The chart of the SIC as per HYCOM corresponds well to the SIC derived from data by the University of Bremen(AMSR2). Repeated Accessibility(RA) in research blocks 4 and 5 with statistical models, where the limit of navigability for fishing vessels is set at 20 % SIC, was calculated. It should become possible to predict the accessibility to research blocks 4 and 5 with the model in cooperation with HYCOM.
