Weddell seals by Scott Base

Weddell seals near Scott Base. In the background, you can see some of the pressure ridges the seals use for safety and feeding during pupping season. In the middle of the image is a hole left by a seal. A seal can lie about for 5–6 hours and their body heat melts the snow underneath it, which then refreezes, leaving a frozen outline of the seal on the ground.
