AMD - DIF Record(s) USAP-1744550_1 Abstract This cvs dataset contains time series of sea ice concentrations from four remote sensing derived products – the Sea Ice Index (Sea Ice Index), AMSR2 and AMSR-E, and National Ice Center NIC Charts. The dataset consists of the daily (or weekly in the case of NIC) timeseries for the available period of record beginning in 1979 for the Sea Ice Index and extending until April 1, 2019. The sea ice concentrations were extracted from the nearest corresponding pixels from the fifteen study sites associated with visited by projects ANT-1744550, -1744570, -1744584, and -1744602 during ARSV Laurence M. Gould cruise LMG 19-04 in April and May 2019. In addition to the original time series, five-year annual means starting on April 1st are computed for the Sea Ice Index, AMSR2 and NIC datasets all of which covered the 2014-2019 period. These five-year means include both annual and summer (October-February).
