Mapping the Lili’uokalani Underwater Mountain Chain (PMNM) | Nautilus Live

Описание: When exploring little-known regions of the ocean, we often need to create our own maps to plan efficient and safe operations. This video features Mapping Coordinator Erin Heffron flying through the data of the over 32,980 km2 mapped during the 20-day long expedition NA133: Luʻuaeaahikiikalipolipo (October 24 - November 13, 2021). That’s almost twice the size of the state of Massachusetts! Using E/V Nautilus’ multibeam echosounder and sub-bottom profiler, we mapped the Lili’uokalani underwater mountain chain inside the Papahānaumokuākea Marine National Monument.
