Sentences with phrase «ice retreat later»

Ice retreat depends strongly on the amount of solar heating of the surface ice and ocean; clear sky conditions early in the melt season can go a long ways towards helping ice retreat later in the season, so this is one of the variables that will be monitored closely (e.g., in the Barrow coastal sea ice break - up forecast, see below).
