"Even though it (the Southern Ocean) spans only 6% of the global ocean surface, it has been estimated to account for 40% of the anthropogenic carbon absorbed by the oceans, thereby considerably slowing climate change." 🌍 A global network of BGC-Argo floats is helping fill critical gaps by profiling the ocean down to 2,000 meters. Equipped with optical and biogeochemical sensors, these autonomous systems measure dissolved oxygen, nitrate, chlorophyll, and light, providing a continuous view of nutrient cycling and carbon transport. Combined with hyperspectral satellite data from missions such as NASA’s PACE, these measurements are providing researchers with a more complete picture of how marine ecosystems function and respond to change. 🛰️ Read more in #PhotonicsFocus: https://lnkd.in/gbT9n3uN
