While exploring at a site informally called 'Te Kawhiti' on the northern edge of the Manihiki Plateau, scientists encountered a deep-sea coral forest. The hard seafloor at the site provided an ideal surface on which corals can grow and provide habitat for a range of animals, much like trees do in a forest on land.

Dive Summary
On May 6, we conducted a series of midwater transects from 1,400 to 300 meters. The dive took place in the Jarvis Unit of the Pacific Remote Islands Marine National Monument, which is one of the few units of the monument where the water column is protected in addition to the seafloor.

Dive Summary
A highlight of the dive at Jarvis Island was observing a group of brittlestars (ophiuroids) capture and eat a squid (Abralia sp.) that was swimming by. Our science team was shocked to see this behavior from a brittlestar.

Dive Summary
Scientists observed several snails on crinoids. As this behavior had not been previously seen, it was unclear as to whether the snails were eating on waste from the crinoids, eating the crinoids themselves, or engaged in mating behavior.

Dive Summary
This hatchetfish was imaged within Pacific Remote Islands Marine National Monument. In order to be nearly invisible in the water column, hatchetfish are highly reflective, have slim profile to limit their shadows, and have photophores on their bellies to mimic downwelling light.
