Terra Nova Bay is a prominent bay along the Scott Coast of Victoria Land, Antarctica, stretching about 74 kilometers in length and lying between Cape Washington to the north and the Drygalski Ice Tongue to the south. The bay opens into the Ross Sea and is characterized by its frequent polynya-a recurring area of open water that persists even in the harsh Antarctic winter. This phenomenon is caused by powerful katabatic winds sweeping down from the Trans-Antarctic Mountains, which push sea ice out of the bay and prevent its reformation. The Drygalski Ice Tongue acts as a barrier, further maintaining the polynya and making Terra Nova Bay one of the few regions along the Antarctic coast that is often ice-free during winter.
Discovered during the British National Antarctic Expedition (Discovery Expedition) led by Robert Falcon Scott from 1901 to 1904, the bay was named after the relief ship Terra Nova. The region is notable for its complex geography, with features such as Oscar Point, Markham Island, Inexpressible Island, and prominent glaciers like Campbell, Priestley, and Larsen, all contributing to the dynamic landscape. The bay is also home to raised Holocene beaches and glacial deposits, offering evidence of past ice sheet fluctuations and geological history.
Terra Nova Bay is a hub for international scientific research. It hosts the Italian Mario Zucchelli Station, the South Korean Jang Bogo Station, and, since 2024, the Chinese Qinling Station on Inexpressible Island. The bay’s coastal marine environment stands out for its high productivity and rich benthic communities, with a remarkable diversity of sponges, anthozoans, and zooplankton. Part of the bay is designated as Antarctic Specially Protected Area (ASPA 161) due to its unique ecological characteristics and the presence of vulnerable species, including a colony of Adélie penguins at Adélie Cove.
The climate of Terra Nova Bay is dominated by strong, cold katabatic winds and low humidity, with temperatures ranging from +2°C in summer to as low as −30°C in winter. These conditions, combined with the bay’s open water and productive ecosystem, make it a key site for studying Antarctic marine and atmospheric processes, glacial history, and the impacts of climate change.
