Australia is intensifying bird flu surveillance along its southern coast, focusing on two migratory seabird species, the giant petrel and brown skua, that have tested positive for the H5N1 virus. These birds travel from subantarctic islands, raising concerns about potential spread to other wildlife and domestic birds.

The world's largest iceberg A23a, which broke off from Antarctica's Filchner-Ronne ice shelf in 1986, has completely broken apart while drifting in the Southern Ocean. The frozen giant, originally covering 4,170 square kilometers, has lost 99% of its original area over four decades of tracking by Russian scientists.
