Description:In August of 2016, NOAA Ship Okeanos Explorer conducted the first-ever deepwater exploration of the Wake Atoll Unit of the Pacific Remote Islands Marine National Monument. (PRIMNM). In total, the ship conducted 14 ROV dives ranging from 350 to 3,136 meters depth. All explored seamounts are flat-topped guyots with mainly pillow lavas coated in ferromanganese crust exposed on their lower flanks. Their tops have increased amounts of carbonate sediment, and some have post-erosional cones. High-density biological communities were documented at four of the 13 surveyed dive sites. Hundreds of different animal species were observed. Of those, a total of 61 specimens were collected, including 20 geological samples and 41 biological samples—19 of which were commensal—that represent either new species or new records for the region. The expedition located and identified the wreck of the Amakasu Maru No. 1, a Japanese World War II-era water tanker. In addition to the science and exploration successes, the ship’s personnel also participated in numerous education and outreach events.
