Nautilus Sets Sail to Explore Uncharted Hawaiian Deep

The Ocean Exploration Trust’s E/V Nautilus has set sail on a 20-day expedition to explore some of the least-known deep-sea habitats around the Hawaiian Islands.

Running from 22 September to 12 October, the expedition will investigate previously unsurveyed areas of seafloor, including unexplored ridges and seamounts in the eastern part of Papahānaumokuākea National Marine Sanctuary and abyssal habitats southwest of the Main Hawaiian Islands.

Although Hawaiʻi’s nearshore waters have been relatively well studied, many areas farther offshore have never been surveyed using modern technology. Scientists aboard Nautilus will use seafloor mapping equipment and remotely operated vehicles to investigate habitats at depths of up to 6,000 metres.

The team will collect high-resolution imagery and environmental data to learn more about deep-sea biodiversity, geology and habitats. A new environmental DNA sampler will also collect traces of DNA from seawater, while a low-light camera system will help researchers study deep-sea corals.

And we can follow along from home. Live footage from the ROV dives and mapping operations will be streamed throughout the expedition, giving viewers the chance to watch discoveries from the deep as they happen.
