BigelowLab/iceout: Freeze/Thaw Phenology Data of Global Lake and River Ice

#' The term phenology in the data set title refers to the seasonal phenomenon of the freezing and thawing of lake and river ice (also known as 'ice-in'/'ice-out' and 'ice-on'/'ice-off' data. Ice-out dates, or the dates of ice break-up, are the annual dates in spring when winter ice cover leaves an inland body of water. Methods are provides to enable convenient access to New England iceout data from the 'USGS' (<https://me.water.usgs.gov/iceout_data>) and Minnesota iceout data from the 'MDNR' (<https://www.dnr.state.mn.us/ice_out/index.html?year=1843>) along with extra Maine state data from 'MDACF' (<https://www.maine.gov/dacf/parks/water_activities/boating/ice_out06.shtml>) and a comprehensive global dataset (to 2014) from the 'NSIDC' (<http://nsidc.org/data/lake_river_ice/>).
