NEWS RELEASE

Antarctica has today become home to a new subsea observatory providing near real-time ocean data, year-round, thanks to a [new partnership](https://www.uvic.ca/news/topics/2024+onc-antarctic+media-release) between Canada and Spain scientists.

Ocean Networks Canada (ONC) has expanded its ocean monitoring infrastructure in the Southern Ocean with the deployment of two deep-sea Argo floats this month which are now transmitting open access ocean data. The scientific instruments were released on February 3, 2024 (GMT) by ONC's partner, the Spanish National Research Council (CSIC), into Drake Passage, the body of water between the southernmost point of South America and the South Shetland Islands of Antarctica (*61 48.27255' S, 64 00.78831' W and 61 48.32472' S, 64 00.788836' W*).

Staff with the 37th Spanish Antarctic Campaign have been hard at work preparing the Ocean Networks Canada (ONC) Antarctic Ocean subsea observatory for the impending harsh polar winter in the southern hemisphere. The observatory - which is a partnership between ONC and the Spanish National Research Council (CSIC) - has been successfully transmitting ocean data since its [January 2024 deployment](https://www.oceannetworks.ca/news-and-stories/stories/data-now-flowing-from-new-antarctic-ocean-observatory/), 25 metres below the surface, in a bay near the Spanish Antarctic Station ([BAE](http://www.utm.csic.es/es/instalaciones/jci)), Juan Carlos I, located on Livingston Island. The research station is staffed during the warmer summer months but inaccessible during the polar winter, so staff have been prepping the observatory to (hopefully) withstand the dramatic seasonal changes ahead. At the height of winter, approximately 15 million square kilometres of sea ice can form at the surface of the Antarctic Ocean (aka the Southern Ocean), that will move with the currents and winds, and collide with each other and the coastline. Watch this video showing how CSIC has armoured and secured the observatory cables to the shore to minimize potential damage by sea ice impact and rough tides.
