IB Biology Topic D4.3.4 Melting of Landfast Ice and Sea Ice as Examples of Polar Habitat Change Revision Notes (SL/HL) | RevisionDojo

Written by official IB examiners

Melting polar ice destroys the platforms species depend on to breed and hunt

Polar regions are warming rapidly, and the loss of landfast ice and sea ice threatens the species that live on it.
These icy habitats are critical breeding and hunting grounds, so their loss disrupts entire food chains.
Loss of landfast ice in Antarctica threatens the breeding grounds of the emperor penguin (Aptenodytes forsteri).
Loss of Arctic sea ice endangers walruses, which rely on ice floes for resting and foraging.

Landfast ice is anchored and stable, while sea ice drifts with the ocean

Definition

Landfast Ice

Ice that is attached to the coastline or the sea floor, remaining stationary.

Definition

Sea Ice

Ice that floats on the ocean surface and is not anchored to the land.

Landfast ice is frozen to the coastline and provides stable platforms for breeding.
Sea ice moves with ocean currents and serves as hunting and resting grounds for walruses, polar bears, and seals.
