About
the Ice-out Study
Background
When the ice
cover melts from lakes, rivers, ponds and oceans it's a welcome sign of
spring. This event is known as "ice-out." Ice-out dates are one
way to measure the greening of springl, and dates can be compared from year to
year.
Watch
for ice-out of your local waters
- Adopt
a frozen body of water near you. You may choose a lake, pond, river,
stream, bay, estuary--or even an ocean.
- Watch
for the exact date that ice-out occurs. We define "ice-out"
as the time the body of water is 90% free of ice.
