Antarctica is emerging as the natural laboratory with the greatest potential for research and recording of environmental parameters to study global climate change, a phenomenon that directly threatens humanity. To address this, a significant amount of information and scientific evidence is needed, which still remains underdeveloped.

​

This reality obliges Antarctic programs to undertake strategic actions to improve the monitoring of environmental variables, presenting an opportunity to achieve this collaboratively for the benefit of Antarctic sciences.Therefore, Chile, through its Antarctic Institute, is carrying out the Latitudinal Sensors Program (PSL).

​

This project establishes the southernmost permanent sensor network in the country, representing a powerful tool for better understanding the dynamics of Antarctic ecosystems and, in turn, confronting global climate change through information and scientific evidence.

​

It is known that Antarctica climatically interacts with other regions of the planet and is seen as a "sentinel" of the impact of these changes. Carbon flux, greenhouse gas levels, rates of atmospheric and oceanic temperature increase, and the ablation of the cryosphere are some of the phenomena that can be studied through this type of monitoring network.Portraits made with data from the sensors project located on the Antarctic Peninsula.
