The researchers estimated that 4-8 feet of meltwater is stored between 15 and 148 feet below the surface during summer and that the water then refreezes
or is released during winter.
They added "ice is likely to form where untreated roads, pavements and cycle paths are left wet after snow melts during the day, or partly melted snow refreezes
, and where wintry showers occur overnight".
Damage could also occur if water seeps into the system, refreezes
and breaks parts when it expands during the refreeze
At the same time, as the snow melts and refreezes
, the grains of snow get larger.
Apparently water beneath the ice sheets refreezes
and warps the surrounding ice upwards.
When the meltwater refreezes
, the scientists said the freezing water gives off heat, which softens the surrounding ice and causes the layers of ice to warp to create what Bell calls "tortured ice."
When it refreezes
, it exudes the heat, again at constant temperature.
Rain or snowmelt that refreezes
may collect on the soil surface and injure the plant.
Then the team will have one day to send down a robot to collect samples before the hole refreezes
oAs far as I know, it is a health hazard to sell frozen prawns in this manner, especially since the customer often refreezes
what he has bought for consumption at a later date,o he explained.
Some Arctic sea ice always melts in summer, generally reaching its lowest level in September before it refreezes
with the coming of winter.
