Oceans cover approximately 71% of Earth's surface yet remain difficult to explore and monitor remotely. Communication challenges, including lengthy propagation delays, Doppler effects due to vehicle and water movement, and the highly dynamic multipath nature of the undersea environment, can result in significant errors and outliers in transmissions, received data measurements, and image analysis.
