Participants are invited to register online, take an ice-cold dip, and post a public photo or video of their personal Penguin Swim on social media using #OCPenguinSwim.

Penguins also stabilize on the sea ice before they dive to find food. If temperatures rise at the current rate, sea ice will be gone from the Arctic by the 2030s. This leaves the species with ...

Now a new study in Marine Ecology Progress Series is investigating links between penguins’ diving efficiency, oxygen storage and aerobic capacities, pre-breeding foraging, and breeding statuses.
