A groundbreaking initiative has recently been launched to monitor the health of the Southern Ocean around Antarctica. A state-of-the-art underwater observatory, approximately the size of an SUV, has been installed near a Spanish research station on Livingston Island in the South Shetlands archipelago. Developed by Ocean Networks Canada in partnership with the Spanish National Research Council, this observatory aims to gather critical data to understand the impact of climate change on the region.
Unlike previous data collection methods, which primarily relied on surface satellites, floating research equipment, and occasional human observations, the underwater observatory provides continuous and real-time measurements of various oceanic variables. These include temperature, oxygen concentration, chlorophyll levels, conductivity, depth, and water clarity. The observatory sends regular updates to Ocean Networks Canada’s online dashboard, ensuring that scientists and researchers can access the information they need to gain valuable insights into the changing conditions of the Southern Ocean.
Kohen Bauer, a senior staff scientist at Ocean Networks Canada, highlights the significance of this continuous time series, rare in the field of oceanography. The observatory’s long-term data collection will enable researchers to detect and analyze changes in ocean circulation, sea ice, glacier formation, ice retreat, and other crucial indicators. Furthermore, this data will contribute to a broader context, connecting local observations to global questions surrounding climate change.
Understanding the Southern Ocean’s role in absorbing carbon dioxide is another critical aspect of the observatory’s mission. Colder oceans, such as the Southern Ocean, have the ability to absorb more CO2 than other regions. Monitoring this process will enhance predictions and forecasts related to climate change and its future implications.
The establishment of this underwater observatory is a response to the call for better observation and monitoring of the Southern Ocean made by hundreds of scientists from around the world. Their statement emphasized the need for a sustained and coordinated observing system to comprehensively understand the current conditions, predict future states, and inform policies and regulations.
By providing invaluable real-time data, this innovative underwater observatory in Antarctica is revolutionizing the study of climate change and its impact on the Southern Ocean. With continuous monitoring and a comprehensive dataset, researchers and scientists can gain vital insights to tackle the challenges presented by our changing planet.
