CLEAN : Expert lays out challenges facing Malaysia plane searchers

The video discusses the challenges of mapping the ocean floor, particularly at great depths like 4500 meters. It explains how data interpolation is used due to widely spaced data points and the difficulty in identifying materials on the ocean floor using echo returns. The process of deep-sea exploration is slow, taking hours to deploy and retrieve vehicles. Weather conditions, such as tropical cyclones, can complicate searches by dispersing debris. The video compares the current search conditions to past events, suggesting that calmer weather may expedite the process.
