"Fiber Optic Cable Unveils Secrets of Arctic Seafloor Permafrost"

Scientists from Sandia National Laboratories are using a fiber optic cable off the coast of Alaska to study the conditions of the Arctic seafloor and improve understanding of global climate change. By analyzing temperature and acoustic data collected from the cable, they have identified areas with significant amounts of ice and determined the bottom of the seafloor permafrost. The research aims to monitor temperature changes, detect seafloor seeps, and provide insights into the impact of thawing permafrost on greenhouse gas emissions.
