In marine environments, TriOS sensors provide essential real-time monitoring of critical water quality parameters such as turbidity, nutrient concentrations, chlorophyll a and dissolved organic matter (CDOM). These measurements are vital for understanding the health and dynamics of marine ecosystems, supporting a wide range of research activities including the study of oceanographic processes, marine biology and the effects of climate change. By providing continuous, high-precision data, TriOS sensors help to detect changes in water composition, such as pollution levels, algale blooms and shifts in nutrient cycles, which can have a significant impact on marine life. In addition, TriOS sensors are designed to withstand harsh marine environments, ensuring reliable long-term performance in open oceans, coastal zones and other aquatic environments.
