    Here's the new sea ice poll for May.

    In March, from 11 votes the average was 4.1 million km2 with a standard deviation of 0.5 million km2.
    In April, from 49 votes the average was also 4.1 million km2 with a standard deviation of 1.0 million km2.

    Extent has varied between 12th and 5th lowest over the last 4 weeks.
    Volume is at 7th lowest on the latest update from PIOMAS (mid May), while the combined SMOS and CryoSat dataset was lowest on record at the end of it's reliable seasonal measurements at the end of April.

    As a reminder, the extent minima since 2010 in millions of km2 from the daily NSIDC data are:

    2020:    3.7
    2019:    4.1
    2018:    4.6
    2017:    4.6
