We may be working in the tropics, but it may come as a real surprise to some that down on the deep-sea floor, the bottom waters we are exploring are near freezing temperatures. As an example, on our dive on Hutchinson Seamount, the surface water temperature was 29.6°C (85.6°F) when we deployed the Deep Discoverer remotely operated vehicle (ROV). When we arrived on bottom at 1,700 meters, the in situ temperature had decreased to a near-freezing 2.6°C (36.7°F).

Hermit crabs are unusual in having a soft posterior region, the abdomen, hidden within a snail shell or other covering. A hermit crab must change shells throughout its life as it grows: that is, unless it is a deepwater hermit crab, family Parapaguridae.

Telepresence is both a blessing and a curse. Ninety-five percent of the time it is an amazing tool that allows NOAA Ship Okeanos Explorer to tap into the intellectual capital of a science team bigger than what even the largest research vessel could accommodate.

Ahh...the feeling I get when the ship starts to move away from the pier for the first time at the start of a cruise is so nice. I can just feel the tension leaving my body and the farther away we get from land, the better I feel. Watching the land drop below the horizon is just a wonderful feeling.

During the expedition’s remotely operated vehicle dive on August 17, we saw a very unusual eel with a long, fleshy extension from its nose. Swimming a mile below the sea surface at a terrace near Gardner Pinnacles in the Papahānaumokuākea National Marine Monument, this eel was both a discovery and a mystery.
