Drift ice is a type of sea ice that has been carried by winds and ocean currents. It is formed from frozen seawater and is often seen in the ocean along the coasts of northern countries such as Canada, Norway, and Russia. In some areas, drift ice can accumulate to form large ice fields.

Drift ice is commonly used as a form of transportation by some Arctic cultures, who use modified boats to traverse the ice. Commercial fishing is also commonly done in drift ice, due to the large number of fish that the ice can attract.

Drift ice is also an important part of the ocean's ecosystem. The ice provides habitats for a variety of aquatic animals, such as seals, walruses, and penguins. The ice also acts as a barrier between cold waters and warm waters, which helps regulate ocean temperatures.

Drift ice can also be hazardous to navigation, as the ice can pile up in large amounts, blocking channels and restricting movement. Icebreakers are often used to break up the ice and allow ships to pass safely.

In some areas, drift ice can also be a source of freshwater. When the ice melts, it can be collected and used for a variety of purposes.

Overall, drift ice is an important part of the ocean's ecosystem, and is an important resource for many communities in the Arctic.
