The Plocan-maintained ocean observatory off the Canary Islands continues to reveal a long-term process of ocean acidification in 2025 [3, 22]. This occurs as the ocean absorbs excessive carbon dioxide from the atmosphere, leading to lower pH levels [5, 6]. The data is being collected as part of Plocan's ongoing efforts to maintain and renew the European Station for Time Series in the Ocean (ESTOC) [5, 6, 20].
Researchers are actively involved in maintaining the observatory, recovering it to install new sensors that ensure continuous monitoring of key meteorological and oceanic parameters [3, 20]. These parameters are crucial for understanding the changes occurring in the ocean [5, 6, 21].
Experts, such as Cianca, note that continued ocean acidification poses a threat to marine flora and fauna [5, 6]. Predictions indicate that temperature patterns will remain above the records of the last 30 years if current trends persist [5, 6]. The ongoing maintenance and renewal campaign are vital for the continuous study of these critical environmental changes [7, 19].
