Who doesn’t love a #DumboOctopus? This one was spotted during a 2019 dive on Kingman Ridges. Dumbos are known for having prominent ear-like fins that extend from the mantle above each eye. Did you know dumbo octopus refers to not one, but a whole genus of umbrella-armed species.

#SampleSpotlight! Pictured is a fragmented lava suspended in lithified sediment. When exposed to UV light, the sediment phosphoresces, glowing green for several seconds. This brief "glow in the dark" effect tells us that the sediment is made out of calcite and/or a phosphate mineral.

During NA174, co-lead scientist Dr. Annette Govindarajan from #WHOI is sampling for #environmentalDNA (#eDNA) to explore the #deepsea #biodiversity in the #MarshallIslands region using the Multipuffer eDNA sampler built by Aquatic Labs integrated onto the #ROVHercules.

For the next few days, we'll be diving with Orpheus Ocean's Orpheus AUV on the abyssal plain habitat east of the #MarianaTrench. Although they are one of the most significant habitats on Earth, abyssal plains remain some of the least explored parts of the planet.

Ocean Exploration Trust @nautiluslive.org · 08/05/2025

Sailing onboard #EVNautilus for the first time this expedition is the Orpheus AUV, from #OrpheusOcean. The Orpheus #AUV will allow the team to explore the abyssal #seafloor at depths up to 6,000 meters, performing high-resolution camera surveys and water and seafloor sampling.

0113

Ocean Exploration Trust @nautiluslive.org · 08/05/2025

The Orpheus AUV is in the water for its first dive of the expedition!

Ocean Exploration Trust @nautiluslive.org · 07/05/2025

The #MarianaIslands region is largely shaped by #platetectonics, with some of the oldest #seafloor on the planet driven into the #MarianaTrench and remelted to bubble up as #magma, forming a chain of volcanic islands and more than 60 subsea #volcanoes.

Ocean Exploration Trust @nautiluslive.org · 05/05/2025

Soon we'll be exploring active underwater #volcanoes in the #Pacific and can't wait to see what cool animals we find! In 2013, #ROVHercules saw this shovel-nosed #chimaera while exploring the collapsed #underwatervolcano #KickemJenny debris field in the #CaribbeanSea.

In the #deepsea, rocky outcrops like these make perfect homes for #corals, #sponges, #crinoids, and the associates that live on them. By growing on a rock or hard substrate, corals and sponges can catch flowing material in the water column for food. 📸: Papahānaumokuākea, 2021

At OET, we explore the deep-sea with our collaborators across the #OECI to understand the #biodiversity of the #deepsea, and one of the best new technologies for investigating this is the study of #environmentalDNA (#eDNA). Watch the video: www.youtube.com/watch?v=OIia...

The solitary #hydroid is a stunning vision in the #deepsea. #Corymorphidae is a family of hydroids that grow on stalks and resemble flowers. Polyps are connected by an epidermal layer that secretes a chitinous skeleton to support the ‘flower’ tentacles on top.
